Overview¶

Epidemiology and Natural History¶

• Pediatric ganglions are more commonly found on the volar surface of the hand and wrist compared to adults [7].
• Pediatric ganglions more commonly have a tendon sheath origin compared to adults [7].
• Approximately 40% of wrist ganglion lesions decrease over the first 6 years after evaluation by a hand surgeon [25].

Diagnosis¶

• Ultrasound is useful for assisting in the diagnosis of suspected flexor tendon sheath ganglions [1].
• Ultrasound is useful for determining whether patients with suspected flexor tendon sheath ganglions should undergo aspiration or surgical excision [1].
• Routine wrist radiography is not cost-effective in the evaluation and treatment decision-making process for patients with a wrist ganglion due to a low prevalence of therapeutically significant findings [21].

Non-Operative Management¶

• A nonsurgical approach to flexor tendon sheath ganglions is both cost-effective and successful [3].
• Most ganglions recur after aspiration [25].
• Percutaneous puncture is a practical option for managing flexor tendon sheath ganglions given its low cost, lack of downtime, and low recurrence rate [5].
• No recurrences were observed after a second puncture in the cohort assessed for percutaneous puncture of flexor sheath ganglions [5].

Operative Management¶

• Surgical excision is a simple, safe, and effective method for treating a painful ganglion of the digital flexor tendon sheath [2].
• Surgical intervention for wrist ganglions has about a 10% recurrence rate [25].
• Surgical intervention for wrist ganglions leaves scars and has some risk for adverse events [25].
• Ultrasound-guided excision of flexor tendon sheath ganglion using a 2-mm portal under local anaesthesia was reliable and efficient without specific morbidity [4].
• Endoscopic ganglionectomy via flexor carpi radialis tendoscopy is a minimally invasive approach that offers better cosmesis and less soft tissue trauma [9].
• Endoscopic ganglionectomy via flexor carpi radialis tendoscopy allows for the management of concomitant FCR tendon pathology [9].
• Endoscopic ganglionectomy via flexor carpi radialis tendoscopy carries risks of recurrence and nerve or vessel injury [9].
• Operation-related complications after arthroscopic volar wrist ganglionectomy are associated with the anatomical location of the ganglion being distal to the bifurcation of the radial artery and concurrently penetrated up to the superficial fascia layer [60].

Pediatric Management¶

• There is no consensus within the literature regarding the best management of pediatric wrist ganglia [22].
• No single treatment modality confers a particular advantage or disadvantage over another for pediatric wrist ganglia [22].

Anatomy & Pathophysiology¶

Flexor Tendon Sheath Anatomy¶

• The fibroosseous tunnel, or digital flexor sheath, extends distally from the metacarpal neck to the proximal aspect of the distal phalanx [75].
• The tendinous sheath consists of annular pulleys that provide mechanical stability and cruciate pulleys that provide flexibility [75].
• The A2 and A4 pulleys are situated over the middle portion of the proximal and middle phalanges, respectively [75].
• The A2 and A4 pulleys are the most essential in maintaining the mechanical advantage of the flexor tendons [75].
• The tenosynovium lining the fibroosseous tunnel supplies both nutrition and lubrication to the poorly vascularized flexor tendons [75].
• Within the sheath, tendon vascularity is supplied via the vincula system, specifically the vinculum longus and brevis [75].
• Anatomical studies have identified two annular and one oblique pulley in the thumb [91].
• A branch from the digital nerve enters the flexor tendon sheath at the same place as the transverse branch of the digital artery [8].
• The nerve branch entering the flexor tendon sheath supplies the nerve fibres found within the vinculum [8].
• The transverse branch of the digital artery enters the edge of the sheath to reach the area of the vinculum brevis [8].

Gliding Mechanisms and Biomechanics¶

• In narrow crowded areas, the gliding mechanism is assured by the synovial sheath, which allows a considerable amplitude of movement [76].
• Fibrous sheaths surrounding synovial sheaths keep the tendon close to the skeleton, particularly when the tendon crosses an articular angle [76].
• The fibrous sheath assumes the role of a pulley when the tendon changes direction [76].
• Each synovial sheath has a visceral and parietal component separated by a potential synovial cavity containing a very thin layer of synovial fluid [76].
• This synovial fluid constitutes the basic gliding and nutritional mechanism for the tendon [76].
• Diffusion is a significant nutrient pathway to the flexor tendon, supporting the importance of sheath closure at the time of tendon suture [36, 37].
• At half the total tendon excursion, the force required to flex the digit through half its range is always less than a third of the force required to flex the digit fully [46].
• The force required to fully flex the digit decreased with more extensive A1 pulley release, becoming significant when more than 50% of the pulley was released [97].

Pathophysiology of Triggering and Ganglions¶

• Triggering results from the loss of smooth gliding of a tendon within its tendon sheath [6].
• Inflammation of the synovium lining the tendon sheath interferes with the normal gliding mechanism [6].
• Interference with the gliding mechanism is especially troublesome at a point of change in direction of a tendon [6].
• Ganglions are defined as cystic swellings closely connected to joints or tendon sheaths which contain mucinous material [141].
• The etiology of ganglions is unknown [141].
• The articular (synovial) theory has gained worldwide acceptance as a scientifically proven explanation for the formation of intraneural ganglions [17].
• Triggering of the finger can occur secondary to a partial flexor tendon tear after closed direct injury [98].

Classification¶

• Volar wrist ganglions may arise from a variety of locations, unlike dorsal wrist ganglions which typically arise from a specific location at the dorsal margin of the scapholunate interosseous membrane [16].
• Approximately two thirds of anterior wrist ganglions reportedly arise from the radiocarpal joint [16].
• One third of anterior wrist ganglions reportedly arise from the scaphotrapezial joint [16].
• Ganglion cysts that arise from the flexor carpi radialis (FCR) sheath are often in a slightly more medial location, either just radial or palmar to the sheath [16].
• Ganglions arising from the FCR sheath are typically less mobile than ganglions arising from the wrist joint [16].
• Ganglions arising from the first extensor compartment tend to adhere to the sheath (extensor retinaculum) [16].
• Ganglions arising from the first extensor compartment tend to be quite firm and are less mobile [16].
• In children aged <10 years, ganglion cysts present on the volar aspect of the wrist [13].
• In patients aged >10 years, ganglions resemble those in the adult population and present on the dorsal aspect of the wrist [13].

Clinical Presentation¶

General Characteristics¶

• Ganglions are the most common cause of focal masses in the hand and foot [50].
• Ganglions commonly arise from the synovium of joints, tendon sheaths, or the epineurium of nerves [50].
• Ganglions are filled with synovial fluid that may become jelly-like over time [50].
• Most patients with intraneural ganglions present with a painless mass [17].
• Some patients with intraneural ganglions present with symptoms of nerve irritation or entrapment neuropathy [17].
• In many patients with intraneural ganglions, definitive diagnosis is made only at the time of surgery [17].

Volar Wrist and Hand¶

• Volar wrist ganglia tend to arise in the interval between the first extensor compartment and flexor carpi radialis (FCR) tendon sheath, just proximal to the wrist flexion crease [16].
• Volar wrist ganglia typically appear to be 1 to 2 cm in size but may be significantly larger at the time of surgical dissection [16].
• Patients with volar wrist ganglions often present with complaints of a mass that has been present for a number of months or years and is typically asymptomatic [16].
• Patients with volar wrist ganglions often note discomfort when the mass is "bumped" [16].
• Volar wrist ganglia are clinically compressible, slightly mobile, nontender, and visible when transilluminated [16].
• Volar wrist ganglia are nonpulsatile but are often intimate with the radial artery, which is palpable alongside the lesion [16].
• Approximately one third of anterior wrist ganglions reportedly arise from the scaphotrapezial joint [16].
• Ganglion cysts that arise from the FCR sheath are often in a slightly more medial location, either just radial or palmar to the sheath [16].
• Ganglion cysts arising from the FCR sheath are typically less mobile than ganglions arising from the wrist joint [16].

Pediatric Population¶

• In children aged <10 years, ganglion cysts are generally amenable to observation with spontaneous regression [13].
• Ganglions in pediatric populations most commonly affect the dorsal wrist [47].
• Ganglions in pediatric populations demonstrate a female predilection [47].
• Pediatric ganglions of the hand have a greater rate of resolution than ganglions of the wrist [52].

Diagnostic Imaging¶

• Ultrasound is useful for assisting in diagnosis and determining whether patients should undergo aspiration or surgical excision for suspected flexor tendon sheath ganglions [1].
• MRI scans provide relatively good reliability in establishing the diagnosis of an occult dorsal wrist ganglion, with a sensitivity of 83% when using intra-operative findings as the standard [48].
• MRI is an excellent diagnostic modality to evaluate rapidly growing upper extremity masses and distinguish ganglions from malignant processes [33].
• The use of the 3-dimensional FSE extended echo train MRI sequence, called cube, has revolutionized the visualization of intraneural ganglions and articular branches that connect them to the joint [17].

Investigations¶

Imaging Modalities¶

• The architecture and relationship of the FDS to FDP within the flexor sheath is accurately defined using a non-invasive imaging technique and the pulley system can be clearly imaged in cross-section [58].
• Sonography-guided wrist arthroscopy provides visualization of the ganglions and ganglion stalk, as well as of the arthroscopic shaver and adjacent structures such as nerves, vessels, and tendons to perform surgery safely [124].
• Sonography-assisted arthroscopy allows clear visualization of ganglia, vessels, nerves, and tendons, enabling safe guidance of the arthroscopic shaver to the lesion without blind resection [126].

Diagnostic Limitations and Utility¶

• The study concludes that routinely performing wrist radiography is not cost-effective in the evaluation and treatment decision-making process for patients with a wrist ganglion due to a low prevalence of therapeutically significant findings [21].
• Radiologists are less likely to identify occult dorsal ganglion cysts on MRI if the cyst is smaller or if the requisition form does not mention a cyst [138].

Pathology and Histology¶

• In patients with the clinical diagnosis of wrist ganglion cyst, quality of care would not be compromised by abandoning the practice of routinely submitting surgical specimens for pathological examination after excision of the ganglion cyst [27, 31].

Treatment¶

Non-Operative Management¶

• Ultrasound imaging assists in determining whether patients with suspected flexor tendon sheath ganglions should undergo aspiration or surgical excision [1].
• Percutaneous puncture is a practical option for managing flexor tendon sheath ganglions due to its low cost, lack of downtime, and low recurrence rate [5].
• No recurrences were observed after a second percutaneous puncture in the cohort assessed for recurrence [5].
• Ganglion aspiration should be considered as a first-line intervention [55].
• Nonsurgical treatment is largely ineffective in treating ganglion cysts, though it may be considered for symptomatic relief in patients who do not want surgery [125].
• Aspiration, with or without cortisone injection, has an average success rate of 35% to 50% [122].
• Approximately 40% of lesions decrease over the first 6 years after evaluation by a hand surgeon [25].

Operative Management¶

• Ultrasound-guided excision of flexor tendon sheath ganglions using a 2-mm portal under local anaesthesia was reliable and efficient without specific morbidity [4].
• Open surgical excision offers a significantly lower chance of recurrence compared with aspiration in the treatment of wrist ganglions [135].
• Surgical intervention for ganglions has about a 10% recurrence rate [25].
• Surgical intervention for ganglions leaves scars and carries some risk for adverse events [25].

• Arthroscopic ganglionectomy through an intrafocal cystic portal is a safe and efficacious option for the treatment of painful wrist ganglia [120].
• Arthroscopic ganglionectomy is a safe and reliable alternative to open resection [140].
• At 12 months follow-up, the rates of recurrence with arthroscopic dorsal ganglion excision are comparable with and not superior to those of open excision [24].
• Routine midcarpal joint exploration during arthroscopic excision of dorsal wrist ganglions appeared to reduce recurrence at 1 year without negatively impacting patient outcomes [35].
• Recurrent ganglion cysts originating from the midcarpal joint are not contraindications for arthroscopic resection [38].
• Arthroscopy allows for the simultaneous treatment of ganglions and other pathologies [29].
• Endoscopic ganglionectomy via flexor carpi radialis tendoscopy is a minimally invasive approach that offers better cosmesis, less soft tissue trauma, and the ability to manage concomitant FCR tendon pathology [9].
• There was no impairment of wrist motion and function in all patients following arthroscopic resection of palmar ganglions [51].
• The key to successful open treatment of dorsal wrist ganglions is excision of the ganglion stalk based at the scapholunate ligament and its associated dorsal-capsular attachments [122].
• Open ganglionectomy creates a defect in the capsule of 1 to 1.5 cm, which is left open [122].
• Stiffness has been reported from prolonged immobilization following open ganglionectomy [122].
• The rate of recurrence for open ganglionectomy can be as high as 40% [122].
• Indications for surgery include pain, restricted motion, and/or aesthetic complaints as a result of the ganglion cyst [113].
• Ultrasound, magnetic resonance imaging, or X-rays are performed to confirm the presence of a ganglion cyst or to rule out other conditions when surgery is indicated [113].
• The operation for dorsal wrist ganglion excision is generally performed under regional anaesthesia and a tourniquet [113].
• A dorsal incision distal to Lister’s tubercle is used, with the extensor retinaculum between the tendons of the second and fourth extensor compartments incised [113].
• A small arthrotomy is performed over the scapholunate ligament, where the dorsal wrist ganglion usually originates [113].
• Complete excision of the ganglion along with its capsule is performed with local synovectomy [113].
• The capsule is either fenestrated or sutured, depending on the surgeon [113].
• A compressive dressing is applied after skin closure and left in place for 3 days [113].
• Active mobilization of the wrist starts after the hand therapist changes the dressing [113].
• Sutures are removed 10 to 14 days postoperatively [113].
• Splints are not used on a regular basis [113].
• Patients start with a stabilizing and strength programme under the guidance of the hand therapist after 3 weeks [113].
• In pediatric wrist ganglion excision, a transverse incision is made over the ganglion to expose the cyst's wall [123].
• Fluid is aspirated and 0.3e0.5 mL of methylene blue is injected into the cavity to facilitate dye penetration into the cyst wall [123].
• The base of the ganglion is ligated with a 4e0 absorbable suture [123].
• All blue-stained ganglion tissue is thoroughly resected [123].
• The wrist is immobilized with a plaster cast for 7 to 10 days following pediatric excision [123].
• Followup examinations occur monthly for 6 months and every 3 months thereafter [123].
• Recurrence is assessed within 48 months' follow-up by palpation alone [123].
• Patients undergoing initial pediatric excision had been treated conservatively for more than 1 year [123].
• Recurrence of the wrist ganglion cyst occurred in 9% of patients in a cohort of 53 arthroscopic resections [116].
• PRWE scores were significantly higher in patients with a recurrence (30 vs. 12, p = 0.002) [116].
• Patients initially presenting with a new ganglion cyst had fewer recurrences at final follow-up compared with patients initially presenting with recurrence (4 vs. 15%) [116].
• Asymptomatic ganglion cysts were left untreated in the arthroscopic cohort [116].
• One patient experienced neuropraxia of the radial superficial nerve, which resolved spontaneously [116].
• One patient developed extensor carpi ulnaris (ECU) tendinitis, which was successfully treated with splinting [116].
• One patient experienced painful scar tissue, which was successfully removed surgically [116].

Complications¶

• Surgical intervention for wrist ganglions carries a recurrence rate of approximately 10% [25].
• Surgical intervention for wrist ganglions leaves scars and carries some risk for adverse events [25].
• Operation-related complications after arthroscopic volar wrist ganglionectomy are associated with the anatomical location of the cyst, specifically when it is distal to the bifurcation of the radial artery and concurrently penetrated up to the superficial fascia layer [60].
• Open surgical excision of pediatric wrist ganglions demonstrates minimal complications [13].

Recovery¶
