مقایسۀ دو رویکرد تانسیون‌ اکتیو زودهنگام و بی‌حرکتی در توان‌بخشی، پس از ترمیم جراحی نواحی ۵‌و‌۶ تاندون‌های اکستانسوری دست

Objective: The objective of the study was to assess and compare Early Active Tension and Immobilization Protocols in Rehabilitation of the Hand, Following Zone 5-6 Extensor Tendon Repair. Materials & Methods: From the 21 patients enrolled in a randomized controlled trial study, 18 cases with average age of 32. 43 years completed the protocol. A total of 41 extensor tendons from 27 fingers of the subjects were studied. A surgeon repaired all tendons in zone 5 and/or 6 by an end to end epitenon running technique using prolen 0.3. For rehabilitation, subjects were randomly assigned into two “Immobilization” and “early active tension” group. Edema, metacarpophalangeal flexion, combined flexion and extension of wrist and fingers, total active motion of fingers and metacarpal extensor lag were assessed 6 weeks after surgery. All aforementioned variables and grip strength were reassessed 12 weeks after surgery. Results: Compared to traditional immobilization protocol, early active tension could significantly improve hand edema, metacarpal flexion, combined flexion and extension of wrist and fingers, total active motion of fingers and grip strength (P0.05). Conclusion: Our results demonstrate that in compliant patients, early active tension could be an alternative method for traditional immobilization protocol, after surgical repair of extensor tendon injuries in zone 5 and/or 6.
