Summary
Functional splinting for extensor tendon injuries in zones V-VIII (thumb zones TIII-TV) allows early active range of motion (ROM) exercises. This technique leads to excellent outcomes and faster return to daily activities with no tenorrhaphy failures.
Area of Science:
- Orthopedic surgery
- Hand surgery
- Reconstructive surgery
Background:
- Extensor tendon injuries in zones V-VIII require effective management to restore function.
- Traditional splinting methods can lead to joint stiffness and prolonged recovery.
- Functional splinting offers a potential alternative for improved outcomes.
Purpose of the Study:
- To evaluate the efficacy of a custom-molded functional splinting technique for extensor tendon repairs in zones V-VIII.
- To assess patient outcomes, including range of motion and return to daily activities.
Main Methods:
- Retrospective review of 22 patients with 61 extensor tendon lacerations (zones V-VIII).
- Application of custom splints 7 days post-surgery, maintaining wrist extension and MP joint flexion, with free IP joints.
- Patients performed active interphalangeal (IP) joint range of motion (ROM) exercises.
Main Results:
- No tenorrhaphy failures reported in any patient.
- At a mean follow-up of 4.5 months, 86% of patients achieved good or excellent results based on active motion.
- No residual impairments affecting daily living or employment status were observed.
Conclusions:
- Functional splinting is an effective technique for extensor tendon repairs in zones V-VIII.
- Early active IP joint ROM, facilitated by functional splinting, reduces joint stiffness compared to static splinting.
- This method provides a less complex and labor-intensive approach than dynamic splinting.
