Summary
Dynamic splinting improves extensor tendon repair outcomes in zones V and VI at 4, 6, and 8 weeks post-surgery. This method offers better total active motion and grip strength compared to static splinting in the early recovery period.
Area of Science:
- Orthopedic Surgery
- Hand Surgery
- Rehabilitation Medicine
Background:
- Extensor tendon injuries in zones V and VI are common.
- Optimal postoperative splinting strategies are crucial for functional recovery.
- Previous studies have yielded mixed results on dynamic versus static splinting.
Purpose of the Study:
- To compare the efficacy of dynamic splinting versus static splinting after extensor tendon repair in zones V and VI.
- To evaluate differences in total active motion and grip strength between the two splinting methods.
- To determine the long-term functional outcomes of each splinting technique.
Main Methods:
- Prospective, randomized, controlled study.
- Inclusion of patients with simple, complete extensor tendon lacerations in zones V and VI.
- Random assignment to either static splinting (n=17) or dynamic splinting (n=17) post-repair.
Main Results:
- Dynamic splinting showed significantly improved total active motion at 4, 6, and 8 weeks compared to static splinting (p<0.05).
- Grip strength was significantly better in the dynamic group at 8 weeks (p=0.004), with 55% achieving >=80% of non-injured hand strength.
- No significant differences in total active motion or grip strength were observed at 6 months between the groups.
Conclusions:
- Dynamic splinting offers superior early functional recovery for extensor tendon repairs in zones V and VI.
- The benefits of dynamic splinting diminish by 6 months post-surgery.
- Dynamic splinting may be recommended for select, motivated patients seeking earlier functional return.
