Summary
The great toe mini wrap-around flap effectively reconstructs distal thumb amputations. This technique offers good sensation and patient satisfaction with minimal donor site issues.
Area of Science:
- Microsurgery
- Hand Surgery
- Reconstructive Surgery
Background:
- Thumb amputations distal to the interphalangeal joint present reconstruction challenges.
- Restoring thumb length, sensation, and appearance is crucial for function.
Purpose of the Study:
- To evaluate the efficacy of the great toe mini wrap-around flap for thumb reconstruction.
- To assess functional outcomes, aesthetic results, and donor site morbidity.
Main Methods:
- A retrospective review of 12 patients undergoing great toe mini wrap-around flap reconstruction for distal thumb amputations.
- The flap included the nail and distal phalanx of the great toe.
- Outcomes assessed included flap survival, sensibility (static two-point discrimination), cold intolerance, and donor site morbidity.
Main Results:
- Eleven of 12 flaps (91.7%) survived.
- Good sensibility was achieved with an average static two-point discrimination of 10 mm (range, 5-15 mm).
- No patients reported cold intolerance, and all were pleased with the thumb's appearance; donor sites had minimal morbidity.
Conclusions:
- The great toe mini wrap-around flap is a reliable and effective method for reconstructing distal thumb amputations.
- This technique provides satisfactory functional and aesthetic outcomes with low complication rates.
