您的感受

桡骨茎突狭窄性腱鞘炎(De Quervain's tenosynovitis)是手腕拇指侧两条肌腱出现的问题。这两条肌腱所穿行的隧道变得肿胀、紧窄,因此肌腱在其中滑动时会引起疼痛。您会在手腕拇指侧、靠近拇指基底部的骨性隆起处感到酸痛和压痛。该部位常常还会出现肿胀。

某些动作会加重疼痛。将手腕向小指方向弯曲、在将手腕向拇指侧弯曲的同时用力抓握,或将拇指与食指捏合,都可能诱发疼痛。需要用到这些动作的日常事务会变得困难:提水壶、转动门把手、抱起小孩、拧干抹布或使用剪刀。有些人在按压疼痛部位时,会感到皮肤下有一种粗糙的摩擦感。

大多数人发现疼痛在使用手部时加剧,休息后缓解。在频繁使用手部的忙碌一天之后,疼痛可能更重。有些人在清晨刚起床时或夜间注意到疼痛。

少数人(约每 100 人中有 1 人)除了疼痛之外,还会发现拇指出现卡住或锁住的情况。这一点值得告诉医生,因为它可能会改变哪些治疗方法效果较好。

何时就医

如果疼痛没有缓解、在数周内逐渐加重、在夜间使您痛醒,或使您无法工作或使用手部,请去看全科医生或要求专科医生评估。

如果您的手或手臂变得发烫、发红、肿胀且疼痛,尤其是伴有发烧时,请当天前往急诊科。这可能是需要当天处理的感染,而且您无需全科医生转诊。如果您的手指或手变得苍白、冰冷、发白或发青,或者在受伤后突然失去感觉或活动能力,也请当天前往急诊科。

如果您无法联系到诊所,例如在非工作时间或周末,请前往离您最近的急诊科。

实际发生了什么

有两条肌腱负责将拇指从手掌旁移开并将其伸直。它们并排穿过手腕拇指侧的一条狭窄隧道。这条隧道有一个坚韧的顶盖,将肌腱固定在靠近骨骼的位置,就像一个导环把两根绳子固定在原位。

问题在于肌腱及其隧道发生了炎症。肿胀的内衬占据了原本就很紧窄的空间,因此肌腱在滑动时会发生摩擦。这种摩擦会引起更多的肿胀和更多的疼痛,隧道本身也可能随着时间推移而变窄。穿过这条狭窄通道的血液供应很差,这使得刺激更难自行平息。

有些人天生在隧道内多出一道壁,将其分隔成两条独立的通道。这一点很重要,因为两条肌腱都需要空间来滑动。如果其中一条肌腱位于自己单独封闭的通道内,那么即使主隧道得到了治疗,这条通道仍可能保持紧窄。

这就解释了您的感受。手腕拇指侧的疼痛部位就是这条隧道本身。抓握、捏取和提物时的疼痛,是肌腱在变窄的空间中被牵拉滑过所致。由于肌腱无法自由滑动,捏力和拇指力量可能会下降。有些人感到的粗糙摩擦感,是变得粗糙的肌腱表面在皮肤下移动所致。

当拇指除了疼痛还出现卡住或锁住时,说明狭窄已严重到足以使肌腱被短暂卡住。这是同一问题较为进展的形式,值得尽早告知医生,因为它会改变哪些治疗方法效果较好。

这里的疼痛也可能来自隧道周围的结构,而非隧道本身:拇指基底部的关节炎、前臂较高处受刺激的肌腱,或穿过手腕这一部位的一条浅表神经。这些情况需要不同的治疗,这就是为什么确定疼痛的确切来源很重要。

我们如何处理该问题

Mater Private Hospital Rockhampton 的上肢外科医生 Kieran Hirpara 医生会从适合您病情的最微创方案入手。我们通常从调整您使用手部的方式开始,并通过手部治疗来平息刺激、减轻肌腱的负荷。将拇指和手腕固定不动的夹板可以让肌腱得到休息,并减少引起疼痛的摩擦。在进入下一步之前,请先认真尝试这些方法;如果情况没有改善,请告诉我们。

针对这种病症证据最充分的治疗是皮质类固醇注射。皮质类固醇是一种抗炎药物,可减轻隧道内的肿胀。单次注射可使 82% 的患者症状得到缓解,其中超过半数患者在至少 12 个月内保持无症状状态。在超声引导下进行注射可以改善效果,也有助于我们确认所治疗的确切部位。注射联合将手腕固定不动的夹板,效果优于单独注射。如果症状复发,第二次注射仍是一个合理的选择,而不意味着注射治疗已经失败。如果您患有糖尿病,单次注射成功的可能性低于其他人,但之后的每一次注射仍会与前一次同样有效。

大多数人不需要手术。当非手术治疗未能带来足够的改善,或拇指除了疼痛还出现卡住和锁住(这种情况往往不会自行缓解)时,我们会考虑手术。手术会松解隧道紧窄的顶盖,使肌腱能够再次自由滑动。这是一项小手术,另有专门页面介绍其具体内容。

预期情况

对大多数人来说,这种病症不会很快自行消失。大多数患上这种病症的人,如果不做任何处理,一年后仍有症状,而且疼痛往往会随着使用而反复发作,而不是逐渐稳定地消退。少数人(约三分之一)最终会在两年内需要手术,其中大多数需要手术的人在第一年内就到了这一步。

如实来说,接受治疗后的前景是良好的。单次皮质类固醇注射可使 70% 的患者症状完全缓解,第二次注射可再治愈 10% 的患者。综合来看,在两次注射之内,注射治疗的成功率为 73.4%。当需要手术时,手术效果良好:88% 的人术后完全满意,手术在 91% 的病例中治愈了这一问题。

恢复的感受取决于您选择哪种治疗途径。注射后,随着隧道内的肿胀消退,酸痛通常会在数天至数周内减轻。手术后,肌腱能够再次自由滑动;与开放手术相比,采用锁孔(内镜)手术时,改善通常来得更早。术后的手部治疗由 Extend Rehabilitation 的 Ruby Doolan 负责。Ruby 是一名手部治疗师:她会指导您的治疗,并为您制作所需的任何夹板。

有些事情值得事先了解。如果您患有糖尿病或代谢综合征(一组健康问题,包括高血压和腹部肥胖),注射对您成功的可能性低于其他人。您对该病症的认知也很重要:预期最坏结果的人往往报告更多的疼痛和更差的功能,因此对这种病症意味着什么抱有准确的预期,而不是心存恐惧,会有所帮助。

如果您的症状没有缓解、在数周内逐渐加重、在夜间使您痛醒,或使您无法工作或使用手部,请去看全科医生或要求专科医生评估。

何时就医

这种病症的大多数警示征象已在上文第一部分中介绍:疼痛没有缓解、在数周内逐渐加重、在夜间使您痛醒,或使您无法工作或使用手部。如果其中任何一项符合您的情况,请去看全科医生或要求专科医生评估。

有一个征象值得在这里再次提及。如果您的拇指除了疼痛还出现卡住或锁住,请告诉为您诊治的医生。这种形式的问题往往无法仅靠休息或夹板缓解,而且它会改变哪些治疗方法效果较好,因此值得尽早告知,而不是等着看它是否会自行消退。

如果疼痛的位置稍微偏离通常的部位,例如位于前臂较高处或拇指基底部上方,同样的建议也适用。其他几种病症可能与这种病症相似,而它们需要不同的治疗。仔细的检查可以确定您患的是哪一种。

如果您的手或手臂变得发烫、发红、肿胀且疼痛,尤其是伴有发烧时,或者您的手指变得苍白、冰冷、发白或发青,请当天前往急诊科。

深入探讨

Advanced reading: the deeper science (optional)

本节内容超出了您自身治疗决策所需的范围。De Quervain 腱鞘炎值得进一步阅读,原因在于存在一种小的解剖学变异,这种变异是导致该手术(尽管通常可靠)后患者满意度低的主要原因;此外,最佳的非手术治疗效果并非在两种疗法中二选一,而是将两种疗法联合使用。

联合疗法优于单一疗法

第一背侧骨筋膜室在腕部拇指侧的隧道内容纳两条肌腱。治疗旨在消除该隧道内的炎症,并减少通过该隧道的负荷。

一项针对 823 名患者的网状荟萃分析得出结论,皮质类固醇注射联合短期固定仍是主要且有效的治疗方法,体外冲击波疗法为次要选择 [1]。直接观察各组成部分,联合支具与皮质类固醇注射的方法比单独使用任一干预措施更有效 [2]。

这比“先尝试夹板,若无效再注射”的指令更为具体。证据支持两者联合使用,即在注射后佩戴夹板一段特定的短期时间。

第二次注射仍然值得进行

当症状复发时,本能的反应是认为注射治疗失败并转向手术。然而,针对大样本队列的数据表明情况并非如此:尽管多次注射的成功率会下降,但重复注射具有较高的成功率,且是一种可行的临床选择 [3]。

随着注射次数增加,成功率下降是预期之中的。但较低的成功率并不等同于无效,第二次注射仍然是一个合理的步骤,而非拖延战术。

解释大多数手术失望的最主要变异

第一背侧间隙松解术是有效的,若疗效未达预期,通常存在特定原因。不满意可能源于松解不完全、肌腱半脱位、神经损伤,或仅仅是恢复期的时长,且未被识别且未松解的拇短伸肌亚腱鞘是独立的不满意来源 [4]。

这一点值得深入剖析,因为它是本节中单一最有用的事实。在相当比例的人群中,该间隙并非单一隧道,而是两个,其中拇短伸肌腱在另一肌腱旁运行于其独立的腱鞘内。仅打开主间隙即停止的松解术会保留该第二腱鞘完好无损,其内部的肌腱仍处于受压状态。腕部被切开,手术按描述完成,但症状持续存在。

这也是为何上述另外两个列出的原因至关重要:松解过宽会导致肌腱在腕部活动时从骨沟中半脱位,产生疼痛性弹响;且桡神经浅支恰好横跨手术野上方。该间隙必须完全但不过度地打开,而神经又位于其间,这正是为何看似轻微的手术也需要与较大手术同等的谨慎对待。

桡侧腕部并非所有病变都是德奎尔万病

该区域的疼痛存在值得了解的鉴别诊断,因为治疗方法各不相同:拇指基底部关节炎、前臂近端数厘米处的交叉综合征以及桡神经刺激,均可能在重叠区域引起疼痛。在腱鞘正上方出现局限性压痛,且在拇指收于掌心时腕关节尺偏可复现疼痛,这些特征提示病变位于腱鞘而非其邻近结构。

Evidence & references

This is the clinical evidence summary written for health professionals. It is technical, and it lists the research this page was built from. You do not need to read it to understand your treatment or to make a decision about it.

Overview

Anatomy and Diagnosis

  • Anatomical variations in the first extensor compartment are clinically relevant to the pathophysiology and treatment of De Quervain's tenosynovitis [1].
  • Wrist radiography does not influence the management of patients presenting with de Quervain tendinopathy [6].
  • The tethered thumb sign is a clinical maneuver that supports the diagnosis of de Quervain tenosynovitis and assists in determining an effective treatment algorithm [12].
  • Ultrasound can be used as a diagnostic tool in the management of de Quervain’s disease [18].

Non-Operative Treatment

  • Corticosteroid injection is the only available nonsurgical treatment that can potentially modify the course of de Quervain's tenosynovitis and is the preferred initial treatment [2].
  • Corticosteroid injection with a short duration of immobilization remains the primary and effective treatment for de Quervain tenosynovitis [28].
  • Corticosteroid injections lead to treatment success 73.4% of the time within 2 injections [22].
  • Although the success rate for the treatment of De Quervain's tenosynovitis decreases with multiple injections, repeat injections have a high rate of success and are a viable clinical option [46].
  • Corticosteroid injection for De Quervain tenosynovitis is not as effective in patients with metabolic syndrome compared with age- and sex-matched controls in terms of functional outcomes and treatment failure [5].
  • Patients with diabetes mellitus have a decreased probability of success following a single corticosteroid injection for de Quervain tenosynovitis in comparison to nondiabetic patients [40].
  • The effectiveness of each additional corticosteroid injection does not appear to diminish in patients with diabetes mellitus [40].
  • Ultrasound-guided triamcinolone injection should be considered to improve the treatment outcome for de Quervain's disease [18].

Operative Treatment

  • Surgical release of De Quervain's tenosynovitis remains the gold standard treatment [10].
  • Surgical intervention is effective as definitive therapy for de Quervain's tenosynovitis, with a cure rate of 91% and 88% of patients indicating full satisfaction [11].
  • The release of the first extensor compartment for refractory de Quervain's disease results in good clinical outcomes with minimal morbidity [24].
  • Longitudinal incision offers the advantage of easy identification of the compartment, more complete releases of tendon sheath and peritendinous adhesions, and less risk of palmar subluxation of tendons [10].
  • The longitudinal incision for release of the first extensor compartment is a safe and effective technique that provides good exposure, protects vital structures, prevents possible tendon subluxation in the postoperative period, and is cosmetically acceptable [17].
  • Endoscopic release for de Quervain's tenosynovitis seems to provide earlier improvement after surgery, with fewer superficial radial nerve complications and greater scar satisfaction, when compared with open release [33].
  • One portal endoscopic assisted release of the extensor compartment is an effective and safe minimal invasive procedure with similar complication rates reported previously in open and endoscopic procedures [31].
  • Endoscopic release of the extensor compartment is an effective and safe procedure in patients with de Quervain's disease who are unresponsive to nonoperative treatments, despite a little increase in operation time [41].
  • Pulley reconstruction should be considered part of the surgical treatment for de Quervain tenosynovitis and gives satisfactory medium-term results [4].

Prognosis and Patient Factors

  • Patients presenting with de Quervain's tenosynovitis may favor initial nonsurgical management [7].
  • Patients who scored lower than 40 for physical function or higher than 60 for pain interference had significantly increased odds of eventually undergoing surgical release for de Quervain tenosynovitis [34].
  • The failure of an operation in De Quervain tenosynovitis is due to anatomical variations, the involvement of the radial superficial nerve, and the ignoring of another syndrome in the proximity [13].
  • Addressing misconceptions about de Quervain's tenosynovitis regarding consequences for patients and symptom duration allows patients to make informed decisions about treatment [9].

Anatomy & Pathophysiology

Anatomical Variations

  • The first dorsal compartment of the wrist exhibits immense anatomical variation, including commonly found supernumerary tendons or tendon slips [107].
  • Variation in tendon insertion is present in the population of the first dorsal compartment [107].
  • Septa or aberrant compartments are present in the first dorsal compartment [107].
  • Bilateral variations are present in the population regarding the anatomy of the first dorsal compartment [107].
  • The superficial branch of the radial nerve is expected to be encountered in more than 50% of patients undergoing surgery for De Quervain's tenosynovitis [94].

Pathophysiology

  • De Quervain's syndrome is defined as a condition where the abductor pollicis longus and extensor pollicis brevis tendons in the first dorsal compartment become inflamed through friction within a tight osteoligamentous tunnel [3].
  • Compromised blood flow and nutrition in the first dorsal compartment lead to the development of adhesions and tendon stenosis [3].
  • De Quervain's syndrome may involve myxoid degeneration, defined as a degenerative process where connective tissues are replaced by a gelatinous or mucoid substance [3].
  • The pathophysiology of De Quervain's disease does not involve inflammation, with histopathological examination showing predominant degenerative changes such as myxoid degeneration and fibrocartilagenous metaplasia [38].
  • De Quervain's tenosynovitis is caused by impaired gliding of the abductor pollicis longus and extensor pollicis brevis tendons [38].
  • Impaired gliding in De Quervain's tenosynovitis is most probably caused by thickening of the extensor retinaculum of the wrist [38].
  • De Quervain's syndrome may not be an isolated pathology and may be associated with trauma, extensor carpi ulnaris involvement, ligament instability, or repetitive strain [3].
  • Operative treatment for distal radius fractures confers a slightly greater risk of developing De Quervain tenosynovitis within 1 year of injury or surgery [105].

Clinical Presentation & Assessment

  • De Quervain's tenosynovitis is characterized by pain, tenderness, and swelling over the thumb side of the wrist at the radial styloid process [38].
  • The condition is especially associated with sideward movements of the wrist and often leads to impairment of thumb function [38].
  • The tethered thumb sign is a clinical maneuver that can support the diagnosis of De Quervain tenosynovitis and assist in determining an effective treatment algorithm [12].
  • Subjects with stenosing tenosynovitis demonstrate a significant decrease in maximum velocity in slow fist tasks [81].
  • In vivo extensor pollicis brevis tendon excursion measures have been quantified, and wrist position has been found to have an influence on excursion [73].
  • The proportion of wrists with a positive extensor pollicis brevis entrapment test was significantly higher among those with two compartments (18 of 22) than among those with one compartment (0 of 4) [97].

Etiology & Risk Factors

  • Women are more affected by De Quervain tenosynovitis than men, potentially due to manual work such as housekeeping activities and child rearing influencing first compartment dynamics [72].
  • Training intensity is a major factor in determining De Quervain disease in volleyball players, with patients in the higher intensity group showing a mean training time quotient of 155 compared to 74 in the lower intensity group [72].
  • The close association of work and repetitive trauma with De Quervain’s disease has been observed, although the exact relationship is controversial [21].
  • Recent studies have disputed the view that repetitive work is causative of De Quervain’s disease, with one review of 100 patients finding no increased incidence in the dominant hand [21].
  • A study of workers in a car plant reported 544 cases of tenosynovitis but only 2 cases of De Quervain’s disease [21].
  • Repetitive work is less contentious as a factor in aggravating symptoms, as tendon movement within a stenosed sheath during activity logically causes pain [21].
  • The process of tendon movement within a stenosed sheath may cause tendon damage through wear and tear, potentially leading to tendon rupture [21].

Complications & Associated Pathology

  • Rupture of the abductor pollicis longus tendon in association with De Quervain’s disease has never been reported in the literature prior to the 2006 case report [21].
  • Volar subluxation of the tendons of the first dorsal compartment can occur after surgery for De Quervain's stenosing tenosynovitis [48].
  • Volar tendon subluxation after De Quervain's release can be treated with a distally based flap of the brachioradialis tendon to prevent tendon prolapse [48].
  • Symptomatic palmar tendon subluxation after surgical release for De Quervain's disease can be avoided by leaving a palmarly based flap of extensor retinaculum [15].
  • Dorsal tendon dislocation after De Quervain's release can occur if the patient overstresses the wrist through forceful extension [80].
  • Repeat provocative testing for volar tendon subluxation following De Quervain’s release revealed volar tendon translation with wrist flexion, with no pain reported [85].
  • Osteoid osteoma of the radial styloid can mimic stenosing tenosynovitis, with correct diagnosis often requiring histological examination when clinical presentation and X-rays are not typical [45].

Classification

Anatomical Variations and Subcompartmentalization

  • The prevalence of a septated first dorsal compartment is considerably higher than previously reported, most notably in patients with De Quervain tenosynovitis [52].
  • In a prospective study of 87 wrists, 22 of 30 patients (73%) who failed non-operative treatment and underwent operative release were found to have a separate compartment for the extensor pollicis brevis [55].
  • The prevalence of a separate compartment for the extensor pollicis brevis in patients failing non-operative treatment is significantly higher than that in the general population, as shown in anatomical studies of cadavers [55].
  • The persistence of an intracompartmental septum between the abductor pollicis longus and extensor pollicis brevis tendons has been described in a mean 43% of wrists in cadaveric studies, with a wide variation ranging from 20 to 75% [39].
  • When the extensor pollicis brevis tendon resides in a subcompartment, it is likely to do so particularly in patients with de Quervain's disease [53].
  • Ultrasound is a useful imaging technique for diagnosing de Quervain's disease and provides important information about anatomic variations within the first extensor compartment [50].
  • The presence of an intracompartmental septum detected by ultrasound is associated with the failure of ultrasound-guided steroid injection in de Quervain’s syndrome [39].

Diagnostic Mimics and Associated Pathologies

  • Extensor pollicis longus tenosynovitis caused by the extensor pollicis longus's unusual course through the first extensor compartment is a very rare condition that mimics de Quervain’s disease [30].
  • An osteoid osteoma of the radial styloid can mimic stenosing tenosynovitis, with correct diagnosis often requiring histological examination when clinical presentation and X-rays are not typical [45].
  • A hemangioma of the extensor pollicis brevis in the first dorsal compartment is an unusual cause of bilateral de Quervain's disease [14].
  • De Quervain’s syndrome may not be an isolated pathology, with potential associations to trauma, extensor carpi ulnaris involvement, ligament instability, and repetitive strain [3].
  • Failure of surgical treatment in De Quervain tenosynovitis can be attributed to anatomical variations, the involvement of the radial superficial nerve, and the ignorance of another syndrome in the proximity [13].
  • The complexities of de Quervain's tendinitis and the diagnosis and treatment of associated diseases and complications are described to help prevent surgical failures and prolonged disabilities in working women [8].

Clinical Presentation and Physical Examination

  • Triggering or locking in extension is an uncommon symptom in de Quervain’s stenosing tenosynovitis, with a prevalence of 1.3% based on a review of 827 consecutive patients [20].
  • A new test for evaluating the first extensor compartment is a useful clinical tool in the diagnosis of De Quervain's tenosynovitis [36].
  • Ultrasound can be used as a diagnostic tool in the management of de Quervain’s disease, in addition to improving treatment outcomes [18].

Epidemiology and Risk Factors

  • In a young, active population, the unadjusted incidence rate of de Quervain’s tenosynovitis was 0.94 per 1000 person-years [54].
  • The adjusted incidence rate ratio for females compared to male patients was 4.45 (95% CI 4.28, 4.62) when controlling for race, age, service, and rank [54].
  • The highest incidence rate of de Quervain’s tenosynovitis was seen in the ≥40-year-old group, with an incidence rate of 1.37 per 1000 person-years [54].
  • The adjusted incidence rate ratio for the ≥40-year-old group compared to the <20-year-old group was 3.65 (95% CI 3.26, 4.09) [54].
  • Non-white race is a risk factor for de Quervain’s tenosynovitis, with an adjusted incidence rate ratio of 1.31 (95% CI 1.21, 1.42) for black race and 1.17 (95% CI 1.05, 1.25) for others compared to white race [54].
  • De Quervain’s syndrome affects around 1.3% of women and 0.5% of men in a population of adults of working age [39].

Pathophysiology

  • De Quervain’s syndrome is defined as a condition where the abductor pollicis longus and extensor pollicis brevis tendons in the first dorsal compartment become inflamed through friction, leading to compromised blood flow, nutrition, adhesions, and tendon stenosis [3].
  • De Quervain’s syndrome may represent a myxoid degeneration, defined as a degenerative process in which connective tissues are replaced by a gelatinous or mucoid substance [3].
  • The role of repetitive work in the causation of de Quervain’s disease is controversial, with some studies disputing it as a primary cause while acknowledging it may aggravate symptoms [21].
  • Rupture of the abductor pollicis longus tendon in association with De Quervain’s disease has never been reported in the literature prior to the 2006 report [21].

Clinical Presentation

Symptoms and Signs

  • Patients typically complain of soreness and tenderness on the radial side of the distal radius that is exacerbated by ulnar deviation of the thumb [59].
  • Symptoms are also exacerbated by a strong grasp combined with flexion and radial deviation of the wrist or by a firm pinching together of the index finger and thumb [59].
  • Physical examination reveals tenderness and swelling directly over the first dorsal compartment [59].

Diagnostic Testing

  • De Quervain disease is diagnosed clinically and no imaging studies are required [64].
  • Wrist radiography does not influence management of patients presenting with de Quervain tendinopathy [6].
  • In a study of 200 patients, no radiographic findings altered the course of treatment in patients with isolated de Quervain's tenosynovitis [62].
  • Wrist imaging is required only in the presence of associated processes that may need to be evaluated, such as previous distal radius or scaphoid fracture, arthritis of the thumb, and instability of the wrist [64].
  • Ultrasound can be useful as a diagnostic tool in the management of de Quervain’s disease [18].
  • Ultrasound is a worthwhile preoperative investigation in case of de Quervain's disease [51].
  • The wrist hyperflexion and abduction of the thumb (WHAT) test is a more specific and sensitive test to diagnose de Quervain tenosynovitis than the Eichhoff’s Test [59].
  • Finkelstein's test is superior to Eichhoff's test in the investigation of de Quervain's disease [63].
  • A new clinical maneuver, the tethered thumb sign, can support the diagnosis of de Quervain tenosynovitis and assist in determining an effective treatment algorithm [12].

Differential Diagnosis and Mimics

  • Extensor pollicis longus tenosynovitis caused by the EPL's unusual course through the first extensor compartment is a very rare condition that mimics de Quervain’s disease [30].
  • Congenital synostosis between the scaphoid and the trapezium can cause tenosynovitis simulating de Quervain's disease [43].
  • The failure of surgical treatment in De Quervain tenosynovitis can be due to anatomical variations, the involvement of the radial superficial nerve, and the ignoring of another syndrome in the proximity [13].
  • In cases with symptoms of de Quervain's syndrome where the constriction involves only the extensor pollicis brevis in a separate compartment, exploration of both compartments is advised [27].

Patient Factors and Perception

  • Providers should remain cognizant that patients presenting with de Quervain's tenosynovitis may favor initial nonsurgical management [7].
  • Most informed patients initially elect symptomatic treatment for de Quervain's disease, and most experience symptom resolution within one year [32].
  • More negative perceptions of the consequences of de Quervain's tenosynovitis and worse pain catastrophizing are associated with worse pain and reduced function at baseline in patients awaiting surgical decompression [25].
  • Addressing misconceptions about de Quervain's tenosynovitis in terms of the consequences for patients and how long their symptoms will last should allow patients to make informed decisions about the treatment that best matches their values [9].

Investigations

Clinical Examination

  • Finkelstein's test is described as a descriptive error that can produce a false positive [16].
  • A staged description of the Finkelstein test has been proposed to address diagnostic accuracy issues [16].
  • A new clinical test for evaluating the first extensor compartment is a useful tool in the diagnosis of De Quervain's tenosynovitis [36].
  • In cases where symptoms suggest de Quervain's syndrome but constriction involves only the extensor pollicis brevis in a separate compartment, exploration of both compartments is advised [27].

Imaging

  • Deferring routine wrist radiography does not affect the management of de Quervain tendinopathy patients [6].
  • Ultrasound is a useful imaging technique for diagnosing de Quervain's disease and provides information about anatomic variations within the first extensor compartment [50].
  • Ultrasound is a worthwhile preoperative investigation in cases of de Quervain's disease [51].
  • Radial styloid abnormalities do not affect the outcome of management for de Quervain's disease [19].
  • An osteoid osteoma of the radial styloid can mimic stenosing tenosynovitis, and correct diagnosis may require histological examination when clinical presentation and X-rays are atypical [45].
  • Congenital synostosis between the scaphoid and the trapezium can cause tenosynovitis that simulates de Quervain's disease [43].
  • Extensor pollicis longus tenosynovitis caused by an unusual course through the first extensor compartment is a rare condition that mimics de Quervain’s disease [30].

Anatomical Variations

  • Anatomical variations in the first extensor compartment are clinically relevant in the pathophysiology and treatment of De Quervain's tenosynovitis [1].
  • The presence of an intracompartmental septum does not significantly affect clinical outcomes or complications following endoscopic release for de Quervain's syndrome [42].
  • When the extensor pollicis brevis tendon is associated with thumb interphalangeal joint extension, it is likely to reside in a subcompartment of the first dorsal compartment, particularly in patients with de Quervain's disease [53].
  • De Quervain's disease may be secondary to extensor pollicis brevis entrapment [29].

Patient Factors and Perception

  • Addressing misconceptions about the consequences of de Quervain's tenosynovitis and symptom duration allows patients to make informed decisions about treatment [9].
  • Growth hormone abuse is associated with a more recalcitrant form of de Quervain tenosynovitis that does not respond well to nonsurgical treatment, increasing the likelihood of surgical decompression [79].

Treatment

Non-Operative Management

  • One or two local injections of 1 ml triamcinolone acetonide 10 mg/ml provided by general practitioners leads to short-term improvement in participants with de Quervain's tenosynovitis compared to placebo [26].
  • Corticosteroid injections are a useful treatment for de Quervain's tenosynovitis, leading to treatment success 73.4% of the time within 2 injections [22].
  • A single cortisone injection was effective in alleviating symptoms of de Quervain tendinopathy in 82% of patients, with over half remaining symptom-free for at least 12 months [67].
  • The combined technique of corticosteroid injection and thumb spica casting was better than injection alone in the treatment of de Quervain tenosynovitis in terms of treatment success and functional outcomes [68].
  • Patients with diabetes mellitus have a decreased probability of success following a single corticosteroid injection for de Quervain tenosynovitis in comparison to nondiabetic patients, but the effectiveness of each additional injection does not appear to diminish [40].
  • Ultrasound should be considered to improve the treatment outcome of corticosteroid injections and can also be useful as a diagnostic tool in the management of de Quervain’s disease [18].
  • Pain and clinical outcomes significantly improved after corticosteroid injection in de Quervain's disease [49].
  • Preliminary results indicate that betamethasone is a superior treatment for De Quervain's tenosynovitis compared to ketorolac injection [70].
  • Splinting has not been shown to provide long-lasting relief beyond allowing the joints to rest in an immobilized position [65].
  • Iontophoresis with dexamethasone may improve functional outcomes, while therapeutic pulsed ultrasound may be effective in decreasing pain in patients with de Quervain's tenosynovitis [69].

Operative Management

  • The release of the first extensor compartment for refractory de Quervain's disease resulted in good clinical outcomes with minimal morbidity [24].
  • An oblique incision coursing along the extensor brevis tendon is preferred for surgical release, though transverse, oblique, or longitudinal incisions are also satisfactory [35].
  • The longitudinal incision for release of the first extensor compartment offers the advantage of easy identification of the compartment, more complete releases of tendon sheath and peritendinous adhesions, and less risk of palmar subluxation of tendons [10].
  • The first dorsal compartment should be opened on its dorsoulnar side during surgical release [35].
  • A volarly based retinacular flap must remain over the released tendons to prevent volar tendon subluxation [35].
  • Symptomatic palmar tendon subluxation after surgical release can be avoided by leaving a palmarly based flap of extensor retinaculum to prevent palmar subluxation of the tendons with wrist flexion [15].
  • Volar subluxation of the tendons of the first dorsal compartment after surgery can be treated with a distally based flap of the brachioradialis tendon [48].
  • One portal endoscopic assisted release of the extensor compartment is an effective and safe minimal invasive procedure with similar complication rates reported previously in open and endoscopic procedures in patients with de Quervain's disease who are unresponsive to non-operative treatments [31].
  • Endoscopic release of the extensor compartment seems to be an effective and safe procedure in patients with de Quervain's disease who are unresponsive to nonoperative treatments, despite a little increase in operation time [41].
  • Pulley reconstruction should be considered part of the surgical treatment for de Quervain tenosynovitis as it gives satisfactory medium-term results [4].
  • The failure of an operation in De Quervain tenosynovitis is due to anatomical variations, the involvement of the radial superficial nerve, and the ignorance of another syndrome in the proximity [13].
  • Anatomical variations are clinically relevant in the pathophysiology and treatment of De Quervain's tenosynovitis [1].
  • Anatomic variations are frequently encountered in recalcitrant cases of de Quervain tenosynovitis, including multiple slips of APL and EPB in its own separate compartment [83].
  • First dorsal compartment release during volar approach for distal radius fracture fixation reduces symptoms in patients with pre-existing De Quervain disease compared with no release [75].

Complications

Surgical Complications

  • Surgical failure in De Quervain tenosynovitis is attributed to anatomical variations, involvement of the radial superficial nerve, and the failure to diagnose another syndrome in the proximity [13].
  • Symptomatic palmar tendon subluxation is a complication of surgical release that can be avoided by leaving a palmarly based flap of extensor retinaculum [15].
  • The longitudinal incision for release of the first extensor compartment prevents possible tendon subluxation in the postoperative period [17].
  • Endoscopic release for de Quervain's tenosynovitis is associated with fewer superficial radial nerve complications compared with open release [33].
  • The longitudinal incision offers a less risk of palmar subluxation of tendons compared to other approaches [10].

Tendon and Structural Complications

  • Rupture of the abductor pollicis longus tendon in association with De Quervain’s disease has been reported, with pathogenesis potentially linked to ongoing tendon damage from wear and tear within the stenosed sheath [21].
  • Longitudinal split tears of the extensor pollicis brevis tendon have been reported in cases of de Quervain's tenosynovitis [16].

Diagnostic and Associated Pathology

  • De Quervain's syndrome may be associated with trauma, extensor carpi ulnaris involvement, ligament instability, or repetitive strain, indicating it may not be an isolated pathology [3].
  • Extensor pollicis longus tenosynovitis caused by the EPL's unusual course through the first extensor compartment is a rare condition that mimics de Quervain’s disease [30].
  • In cases where constriction involves only the extensor pollicis brevis in a separate compartment, exploration of both compartments is advised to avoid diagnostic error [27].
  • The complexities of de Quervain's tendinitis and associated diseases and complications are described to help prevent surgical failures and prolonged disabilities in working women [8].

Recovery

Non-Operative Management

  • A single injection of steroid gives complete and lasting relief in 70% of patients with de Quervain's disease, and a further 10% will be cured by a second injection [91].

Operative Management

  • Only 34.9% of patients with new stenosing tenosynovitis required surgery within a 2-year follow-up period, with most progressing to surgery within 1 year of presentation [93].

Surgical Technique and Complications

  • Pulley reconstruction as part of the surgical treatment for de Quervain tenosynovitis gives satisfactory medium-term results and should be considered part of the surgical treatment [4].

Patient Factors and Prognosis

  • More negative perceptions of the consequences of de Quervain's tenosynovitis and worse pain catastrophizing are associated with worse pain and reduced function at baseline in patients awaiting surgical decompression of de Quervain's tenosynovitis [25].

The Licensor authorizes You to exercise the Licensed Rights in all media and formats whether now known or hereafter created, and to make technical modifications necessary to do so. The Licensor waives and/or agrees not to assert any right or authority to forbid You from making technical modifications necessary to exercise the Licensed Rights, including technical modifications necessary to circumvent Effective Technological Measures. For purposes of this Public License, simply making modifications authorized by this Section 2(a) (4) never produces Adapted Material.

5. Downstream recipients.

a. Offer from the Licensor -- Licensed Material. Every recipient of the Licensed Material automatically receives an offer from the Licensor to exercise the Licensed Rights under the terms and conditions of this Public License.

b. No downstream restrictions. You may not offer or impose any additional or different terms or conditions on, or apply any Effective Technological Measures to, the Licensed Material if doing so restricts exercise of the Licensed Rights by any recipient of the Licensed Material.

Nothing in this Public License constitutes or may be construed as permission to assert or imply that You are, or that Your use of the Licensed Material is, connected with, or sponsored, endorsed, or granted official status by, the Licensor or others designated to receive attribution as provided in Section 3(a)(1)(A)(i).

b. Other rights.

Section 4 -- Sui Generis Database Rights.

Where the Licensed Rights include Sui Generis Database Rights that apply to Your use of the Licensed Material:

a. for the avoidance of doubt, Section 2(a)(1) grants You the right to extract, reuse, reproduce, and Share all or a substantial portion of the contents of the database for NonCommercial purposes only;

b. if You include all or a substantial portion of the database contents in a database in which You have Sui Generis Database Rights, then the database in which You have Sui Generis Database Rights (but not its individual contents) is Adapted Material; and

c. You must comply with the conditions in Section 3(a) if You Share all or a substantial portion of the contents of the database.

For the avoidance of doubt, this Section 4 supplements and does not replace Your obligations under this Public License where the Licensed Rights include other Copyright and Similar Rights.

a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION, WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT KNOWN OR DISCOVERABLE.

WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.

c. The disclaimer of warranties and limitation of liability provided above shall be interpreted in a manner that, to the extent possible, most closely approximates an absolute disclaimer and waiver of all liability.

Section 6 -- Term and Termination.

a. This Public License applies for the term of the Copyright and Similar Rights licensed here. However, if You fail to comply with this Public License, then Your rights under this Public License terminate automatically.

b. Where Your right to use the Licensed Material has terminated under Section 6(a), it reinstates:

1. automatically as of the date the violation is cured, provided it is cured within 30 days of Your discovery of the violation; or

2. upon express reinstatement by the Licensor.

For the avoidance of doubt, this Section 6(b) does not affect any right the Licensor may have to seek remedies for Your violations of this Public License.

c. For the avoidance of doubt, the Licensor may also offer the Licensed Material under separate terms or conditions or stop distributing the Licensed Material at any time; however, doing so will not terminate this Public License.

d. Sections 1, 5, 6, 7, and 8 survive termination of this Public License.

b. To the extent possible, if any provision of this Public License is deemed unenforceable, it shall be automatically reformed to the minimum extent necessary to make it enforceable.

c. No term or condition of this Public License will be waived and no failure to comply consented to unless expressly agreed to by the Licensor.
