本指南由基兰·希尔帕拉（Kieran Hirpara）医生在罗克汉普顿 Mater 私立医院为您提供扳机指松解术后的康复指导。它说明了您术后的预期情况、需遵循的注意事项以及术后锻炼计划：请将此页面或其 PDF 文件带给您的物理治疗师或手治疗师，以确保您的康复过程协调一致。

如果您在术后对伤口有任何担忧，请与诊所联系。拍摄伤口照片并通过电子邮件发送以供审查通常很有帮助。

预期情况

伤口护理说明见单独页面：请参阅本方案末尾链接的伤口护理页面。

以下练习对于防止肌腱在伤口愈合过程中粘连至关重要。术后手指关节有时会出现僵硬。早期预防僵硬非常重要，因此建议您使用另一只手对患指进行有力且持续的牵伸，尤其是针对伸直方向的牵伸。这种被动牵伸是安全的，不会影响手术效果：因为滑车系统已经释放，所以牵伸不会干扰内部结构。

伤口愈合后，在进行这些练习前，请先对手部热敷 15 分钟。练习结束后，冰敷可能有助于预防炎症。

手部或伤口有时会出现敏感现象。这是正常现象，可通过立即开始每日脱敏训练来预防或减轻：在敷料覆盖下，轻轻敲击或摩擦伤口区域。这种“感觉反馈”有助于皮肤恢复正常触觉和质感。

在术后最初的 48 小时内，应努力控制肿胀：抬高患手，使用冰敷，如果治疗师提供了加压装置请予以使用，并轻轻“泵动”手指（张开和握紧）以促进肿胀消退。

一旦疼痛允许，应尽早开始用手进行轻度活动（如穿衣、进食等），并逐渐增加强度。切勿过度：如果某项活动后疼痛或肿胀明显增加，请减少活动量直至手部症状缓解，然后再逐步增加活动量。

伤口完全愈合后，开始进行瘢痕按摩：沿切口部位进行有力的环形按摩。伤口护理页面提供了更多关于瘢痕管理的详细信息。

关于恢复的证据

A1 滑车的开放松解术是一项成熟的手术，在已发表的文献中有着良好的记录。手术本身即可纠正卡顿和锁定现象：一旦滑车被切断，肌腱即可再次自由滑动，扳机指现象通常不会复发。在将近 1,600 例开放松解术的系列研究中，少于 1% 的患者因持续性或复发性扳机指需要二次手术，且无神经损伤或深部感染 [4]。一项随访超过三年的比较研究同样发现，开放松解术后无复发病例 [5]。

手掌部位的酸痛感在一到两周内会显著缓解。在一项比较研究中，开放松解术后疼痛显著减轻的中位时间约为 1 周 [5]。此后，手掌在用力握持时可能仍有压痛，并伴有轻度肿胀或手指僵硬，这种情况可能会持续数周。这是正常现象，反映了瘢痕成熟的过程，该过程大约需要三个月 [3]；本方案中的脱敏、瘢痕按摩和锻炼计划正是为了管理这一情况。在上述大型系列研究中，约 1/20 的手指在术后出现了记录在案的问题，最常见的是暂时性僵硬或瘢痕压痛，经治疗后缓解；糖尿病患者的功能恢复往往较慢，因此该群体对锻炼计划的需求更为重要 [4]。

已发表的手部治疗方案建议在术后最初几天内开始主动和被动的手指活动及肌腱滑动练习，待伤口愈合后增加瘢痕管理和脱敏治疗，随后再逐步引入分级握力强化训练 [2][3]，这与本页面程序所采用的分阶段方法相同。早期开始锻炼是保持肌腱滑动和关节灵活的关键，同时促进伤口愈合。

重返工作岗位取决于您的工作对手部的要求。在一项比较研究中，约一半的患者在开放松解术后约 2 周重返工作岗位 [5]；从事较轻工作或办公室工作的人员通常能更早复工，而从事较重体力劳动的人员则需等到解除下方的提举和握持限制后方可复工。

一项随机对照试验比较了开放松解术后三个月的 supervised therapy（监督治疗）与自我指导的家庭锻炼计划：在六个月时，两组在整体功能、活动度和疼痛方面相似，接受监督治疗的患者握力恢复更好；明确从正式治疗中受益的患者是那些术前扳机指症状持续超过 12 个月以及从事家务或较轻工作的人群 [1]。在实际应用中，执行良好的家庭锻炼计划（本页面的练习）足以使大多数患者顺利恢复，而在术前手指僵硬时间较长或进展缓慢的情况下，正式的手部治疗能增加价值。

注意事项与限制

鼓励对手部进行轻度功能性使用，以完成日常活动，如自我护理、进食、穿衣、书写和打字。需注意的限制如下：

  • 术后长达 4 周内，避免提举、抓握和负重。
  • 术后第一周限制驾驶；待疼痛允许、能够握紧全拳，且能安全操控车辆时，方可恢复驾驶。

致您的物理治疗师：

管理方案

  • 家庭锻炼计划，详见下方卡片：腕关节屈曲/伸展拉伸；DIP（远端指间关节）和 PIP（近端指间关节）关节阻挡训练；肌腱滑动练习（A 组和 B 组）
  • 对指关节进行持续有力的被动拉伸，尤其是向伸展方向，以早期预防关节僵硬
  • 伤口愈合后，在锻炼前对手部热敷 15 分钟；锻炼后冰敷以预防炎症
  • 术后即刻开始每日脱敏治疗（在伤口及原位敷料上进行轻柔拍打/摩擦）
  • 术后前 48 小时的管理肿胀措施：抬高患肢、冰敷、酌情加压、轻柔的手指泵动练习
  • 根据疼痛耐受情况，逐步恢复轻度功能性使用，并监测活动后疼痛/肿胀的波动
  • 伤口完全愈合后，进行瘢痕按摩（沿切口进行有力的环形按摩）

注意事项

  • 仅进行轻度功能性使用以完成日常活动（自我护理、进食、穿衣、书写、打字）
  • 术后长达 4 周内，禁止提举、抓握或负重
  • 术后第一周限制驾驶；待疼痛允许、能够握紧全拳且患者能安全操控车辆时，方可恢复

预期里程碑（基于标准，参照已发表的方案 [1][2][3]）

  • 术后 1–2 周内，疼痛通过简单镇痛药即可缓解至舒适水平 [5]
  • 术后 2–3 周内，伤口愈合，并开始进行瘢痕按摩及持续的脱敏治疗 [2][3]
  • 约 3 周时，恢复并维持指关节完全主动屈曲和伸展（全拳及完全复合伸展），这通过关节阻挡和肌腱滑动计划实现 [2]
  • 在解除术后 4 周的提举/抓握限制后，引入渐进式握力和捏力强化训练（如使用训练泥），并逐步过渡到完全功能性使用
  • 若术前扳机指症状持续超过 12 个月，或患者角色涉及持续的轻度/精细手部使用，或关节活动度或握力恢复缓慢，则考虑升级至 supervised hand therapy（监督下的手部治疗） [1]

以下是您讲义中的锻炼方法，于术后开始，并在物理治疗师或手部治疗师的指导下于家中继续进行。

Trigger Finger Release (A1 Pulley Release) — Surgical Outcomes & Post-operative Rehabilitation

Topic scope: (A) the place of surgery in stenosing tenosynovitis (trigger finger/thumb) after failed conservative care (splinting, corticosteroid injection), and (B) post-operative rehabilitation after surgical division of the A1 pulley — open or percutaneous. This is an early-motion pathway: nothing is reconstructed, the catching is mechanically abolished the moment the pulley is divided, and the rehab exists to keep the now-free tendon gliding and the finger joints supple while the wound heals.

Defining principle of the rehab here: A1 pulley release removes the obstruction; it does not create a construct that needs protecting. Once the pulley is divided the flexor tendon glides freely and triggering does not usually recur. So — unlike a tendon repair, and like a carpal-tunnel decompression — the pathway is immediate active motion: full active finger flexion/extension and tendon glides from the first days, oedema and scar care, early light functional use, and a quick return. Most patients need no formal hand therapy at all; supervised therapy is reserved for the minority with pre-existing joint stiffness, long-standing triggering, or slow recovery. The single branch point is whether the finger was already stiff before surgery (long-standing fixed flexion / PIP contracture) — those patients need active therapy to recover motion the release alone cannot restore.

A. WHERE SURGERY SITS IN THE PATHWAY

Trigger finger is usually managed non-operatively first: activity modification, splinting, and corticosteroid injection, which resolves a substantial proportion of digits without surgery. Surgery (A1 pulley release) is reserved for digits that fail injection, recur, or present with a fixed deformity. The corpus contains the comparative evidence underpinning this stepped approach (percutaneous release vs steroid injection; one- vs two-injection regimens; corticosteroid solution choice) — Moderate (RCT). The rehab protocol on the patient page begins after that decision has been made, so this brief concentrates on the surgical and post-surgical evidence.

B. SURGICAL OUTCOMES & RESOLUTION RATES

Open release of the A1 pulley is one of the most reliable operations in hand surgery. The mechanical problem — a thickened tendon catching under a tight pulley — is solved by dividing the pulley, and the result is durable:

  • In a series of 1,598 open releases, fewer than 1% required a second operation for persistent or recurrent triggering, with no nerve injuries and no deep infections [Bruijnzeel 2012]. About one digit in twenty had a documented post-operative problem, almost all minor and self-limiting (transient stiffness, scar tenderness). Strong (large cohort).
  • Recovery of motion is slower in patients with diabetes, reinforcing the value of the exercise program in that group [Bruijnzeel 2012]. Moderate.
  • A propensity-matched comparison with >3 years follow-up found no recurrences after open release, with median time to significant pain reduction of about one week and roughly half of patients back at work within ~2 weeks [Chanthanapodi 2025]. Moderate.

Take-home for rehab: because the operation itself abolishes the triggering, the rehabilitation is not "earning back" a surgical result — it is preventing the two things that can go wrong during healing: tendon adhesion and joint stiffness. Early glide and early extension are the levers.

C. OPEN vs PERCUTANEOUS RELEASE

Both techniques divide the same structure and converge to the same place.

  • A Level I meta-analysis of 8 RCTs (548 patients) found no significant difference between open and percutaneous release in revision, complication, or pain rates — both are appropriate options [Casey 2024, J Hand Surg Am]. Strong (meta-analysis of RCTs).
  • Larger RCT syntheses show percutaneous release confers faster early functional recovery — better short/mid-term Q-DASH, ~12 days earlier return to work, and shorter analgesic use — while long-term function, grip, motion and complication/revision rates are equivalent. Strong.
  • Percutaneous (including ultrasound-guided/sonographically-controlled) technique is supported by multiple corpus series for efficacy and safety, with the main theoretical risks being incomplete release and digital nerve proximity, mitigated by surface landmarks and imaging [corpus percutaneous series]. Moderate.

Rehab implication: the post-operative program is essentially the same for both approaches — early active motion, glides, oedema and scar care. The patient page applies regardless of whether the release was open or percutaneous; percutaneous patients simply tend to be comfortable and back to activity a little sooner.

D. THE ROLE — AND LIMITS — OF POST-OPERATIVE HAND THERAPY

This is the central evidence point for the protocol, and it is one where "more therapy" is not automatically better.

  • A prospective RCT compared 3 months of supervised rehabilitation after open release against a self-directed home exercise program: at six months, overall function, motion and pain were similar between groups. Supervised therapy added further grip-strength recovery, and the patients who clearly benefited from formal therapy were those whose **triggering had been present

    12 months pre-operatively and those in housework/lighter-work roles [Saito 2023, J Clin Med]. Moderate (single RCT).

  • Published surgeon and hand-therapy protocols (e.g. University of Virginia Hand Center; Twin Cities Orthopedics) start active and passive finger motion and tendon glides within the first days, add scar massage and desensitisation once the wound is healed, and reintroduce graded grip strengthening later — precisely the staged structure of the patient page. Consensus.

Bottom line: a well-performed home program carries most patients through. Formal hand therapy is reserved, not routine — escalate it for long-standing pre-operative triggering, pre-existing joint stiffness/contracture, manual or fine-use occupational demands, or slow motion/grip recovery.

E. COMPLICATIONS

Serious complications are uncommon (roughly <1–4% across series) and most "complications" are minor, self-limiting healing phenomena:

  • Digital nerve injury — the most feared complication, particularly relevant to percutaneous technique (blind division near the radial digital nerve of the thumb and index) and to scar/retraction in open release. Rare in experienced hands; transient paraesthesia is more common than true division [corpus complication series]. Moderate.
  • Incomplete release / persistent triggering — failure to fully divide the A1 pulley (or an A2/FDS slip contribution); a recognised cause of revision, more often discussed with percutaneous technique. Moderate.
  • Recurrent triggering — uncommon after adequate open release (<1% reoperation in the 1,598-digit series) [Bruijnzeel 2012]. Strong.
  • Infection — usually superficial; deep infection rare (none in the large open series) [Bruijnzeel 2012]. Strong.
  • Bowstringing — a rare complication from excessive proximal pulley loss (A1 plus encroachment on A2); largely avoided by limiting division to A1 [bowstringing case literature]. Weak (case-level).
  • Stiffness / flexion contracture / "flare" — the commonest self-limiting problem; transient PIP stiffness, scar tenderness and a post-operative inflammatory flare that settle with the motion, desensitisation and scar program. Recovery is slower in diabetes. Moderate. This is the category the rehabilitation program actively targets.

F. PHASED POST-OP TIMELINE (matches the patient protocol)

Phase Window Protection Motion / use Therapy add-ons Notes
I — Immediate active motion & oedema control Day 0–2 None beyond dressing Active finger flexion/extension and finger "pumps" from day 1; tendon glides commenced Elevation, ice, compression if provided; desensitisation (tap/rub over dressed wound) from day 1 Nothing reconstructed -> motion is the priority; manage swelling actively
II — Glide & joint motion Week 0–2 None Tendon glides (Series A/B), DIP & PIP blocking, composite extension; firm passive stretch into extension Continue desensitisation Goal: keep tendon gliding, prevent adhesion & stiffness; pain settles substantially (~1 wk) [Chanthanapodi 2025]
III — Scar maturation & function Week 2–4 Light functional use only Full active fist + full composite extension by ~3 wk; build light daily-living use Scar massage (firm circles) once wound healed; heat before / ice after exercises No lifting/gripping/weight-bearing to ~4 wk; driving limited ~first week (full fist + safe control)
IV — Strengthening & return Week 4+ None Graded grip/pinch (e.g. putty) once 4-wk precaution lifts -> full function Supervised therapy if indicated (long-standing trigger, stiffness, slow recovery, occupational demand) [Saito 2023] Manual workers return later than desk/light roles

Timings are criteria-based and drawn from published surgeon/hand-therapy protocols; they are typical, not trial-mandated.

G. KEY CONTROVERSIES / EVIDENCE QUALITY

  1. Is routine post-op hand therapy necessary? The best available evidence (Saito 2023 RCT) says no for most — home exercise matches supervised therapy on function/pain/motion at six months, with supervised therapy adding grip strength and benefiting a defined subgroup (long-standing trigger, lighter-work roles). The protocol's "therapy reserved, not routine" stance is evidence-aligned. Moderate.
  2. Open vs percutaneous. Equivalent long-term outcomes and safety (Casey 2024 meta-analysis); percutaneous offers faster early recovery. The rehab is the same either way. The live debate is technique-side (nerve safety, completeness of release), not rehab-side. Strong on equivalence.
  3. The rehab protocol structure itself is consensus/expert, built from surgeon patient-guidance documents plus one rehabilitation RCT — there is no large trial dictating exact phase timings.
  4. Diabetes modifies recovery — slower motion recovery and a lower threshold to involve a hand therapist; not a different protocol, a different pace. Moderate.

H. EVIDENCE STRENGTH FLAGS (summary)

  • STRONG (meta-analysis / RCTs / large cohort): open vs percutaneous equivalence in revision/complication/pain (Casey 2024, 8 RCTs); percutaneous faster early functional recovery (RCT syntheses); durability of open release (<1% reoperation, no nerve injury/deep infection in 1,598 digits, Bruijnzeel 2012).
  • MODERATE (single RCT / cohorts): home exercise ~ supervised therapy at 6 months with grip-strength edge for supervised therapy (Saito 2023); percutaneous efficacy/safety series; slower recovery in diabetes; injection-vs- surgery comparative data.
  • WEAK / CONSENSUS: the post-operative rehabilitation protocol structure and exact phase timings (surgeon/hand-therapy patient-guidance documents); bowstringing risk (case-level).

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.

6. No endorsement. 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.

1. Moral rights, such as the right of integrity, are not licensed under this Public License, nor are publicity, privacy, and/or other similar personality rights; however, to the extent possible, the Licensor waives and/or agrees not to assert any such rights held by the Licensor to the limited extent necessary to allow You to exercise the Licensed Rights, but not otherwise.

2. Patent and trademark rights are not licensed under this Public License.

3. To the extent possible, the Licensor waives any right to collect royalties from You for the exercise of the Licensed Rights, whether directly or through a collecting society under any voluntary or waivable statutory or compulsory licensing scheme. In all other cases the Licensor expressly reserves any right to collect such royalties, including when the Licensed Material is used other than for NonCommercial purposes.

Section 3 -- License Conditions.

Your exercise of the Licensed Rights is expressly made subject to the following conditions.

a. Attribution.

1. If You Share the Licensed Material (including in modified form), You must:

a. retain the following if it is supplied by the Licensor with the Licensed Material:

i. identification of the creator(s) of the Licensed Material and any others designated to receive attribution, in any reasonable manner requested by the Licensor (including by pseudonym if designated);

ii. a copyright notice;

iii. a notice that refers to this Public License;

iv. a notice that refers to the disclaimer of warranties;

v. a URI or hyperlink to the Licensed Material to the extent reasonably practicable;

b. indicate if You modified the Licensed Material and retain an indication of any previous modifications; and

c. indicate the Licensed Material is licensed under this Public License, and include the text of, or the URI or hyperlink to, this Public License.

2. You may satisfy the conditions in Section 3(a)(1) in any reasonable manner based on the medium, means, and context in which You Share the Licensed Material. For example, it may be reasonable to satisfy the conditions by providing a URI or hyperlink to a resource that includes the required information.

3. If requested by the Licensor, You must remove any of the information required by Section 3(a)(1)(A) to the extent reasonably practicable.

4. If You Share Adapted Material You produce, the Adapter's License You apply must not prevent recipients of the Adapted Material from complying with this Public License.

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.

Section 5 -- Disclaimer of Warranties and Limitation of Liability.

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 DISCLAIMERS OF WARRANTIES ARE NOT ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.

b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION, NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT, INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES, COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR DAMAGES. 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.

Section 7 -- Other Terms and Conditions.

a. The Licensor shall not be bound by any additional or different terms or conditions communicated by You unless expressly agreed.

b. Any arrangements, understandings, or agreements regarding the Licensed Material not stated herein are separate from and independent of the terms and conditions of this Public License.

Section 8 -- Interpretation.

a. For the avoidance of doubt, this Public License does not, and shall not be interpreted to, reduce, limit, restrict, or impose conditions on any use of the Licensed Material that could lawfully be made without permission under 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. If the provision cannot be reformed, it shall be severed from this Public License without affecting the enforceability of the remaining terms and conditions.

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.

d. Nothing in this Public License constitutes or may be interpreted as a limitation upon, or waiver of, any privileges and immunities that apply to the Licensor or You, including from the legal processes of any jurisdiction or authority.
