Summary
Opponensplasty restores thumb opposition using various tendon transfers. Most patients achieved good to excellent results, improving pinch strength and function.
Area of Science:
- Hand surgery
- Reconstructive surgery
Background:
- Thumb opposition is crucial for hand function.
- Various surgical techniques exist to restore thumb opposition.
Purpose of the Study:
- To evaluate the outcomes of different opponensplasty procedures.
- To assess the effectiveness of tendon transfers in restoring thumb opposition and pinch strength.
Main Methods:
- Twenty-three opponensplasties were performed in 21 subjects.
- Procedures included flexor sublimis transfer, brachioradialis transfer, Makin's translocation, and a modified Makin's procedure.
- Outcomes were graded for overall results and pinch power.
Main Results:
- Excellent or good results were achieved in 19 out of 23 hands (82.6%).
- Pinch power was graded as good or fair in 21 out of 23 hands (91.3%).
- One case had poor overall results, and two had poor pinch power.
Conclusions:
- Opponensplasty is a viable surgical option for restoring thumb opposition.
- Various tendon transfer techniques can effectively improve thumb function and pinch strength.
- It is generally possible to devise a suitable procedure for thumb opposition restoration.
