Summary
This study demonstrates a successful finger-pulp reconstruction using a free flap from an extra thumb digit. The technique provided a sensitive, well-padded fingertip and corrected polydactyly simultaneously.
Area of Science:
- Plastic Surgery
- Reconstructive Surgery
- Hand Surgery
Background:
- Traumatic finger injuries often require complex reconstruction.
- Polydactyly, particularly of the thumb, can present unique surgical challenges.
Observation:
- A patient with post-traumatic finger pulp defect and uncorrected thumb polydactyly was treated.
- A free flap was harvested from the excised polydactylous digit for reconstruction.
Findings:
- The finger-pulp reconstruction achieved a satisfactory outcome with a well-padded and sensitive fingertip.
- Static two-point discrimination of 3 mm was achieved, indicating good sensory recovery.
- The procedure also successfully corrected the pre-existing thumb polydactyly, improving both function and aesthetics.
Implications:
- This case highlights an innovative approach to finger-pulp reconstruction by utilizing tissue from a coincidental polydactylous digit.
- The technique offers a dual benefit of defect repair and congenital anomaly correction in a single procedure.
- This method may be considered for similar complex cases in hand surgery, optimizing patient outcomes.
