Summary
The double-innervated flap restores tactile sensation to the thumb, offering a functional advantage over other methods for thumb pulp reconstruction. This technique enhances prehension area sensitivity.
Area of Science:
- Plastic Surgery
- Reconstructive Surgery
- Microsurgery
Context:
- Restoring sensation in the thumb is crucial for hand function.
- Traditional island flaps have limitations in covering the prehension area.
Purpose:
- To evaluate the double-innervated flap for thumb sensibility restoration.
- To compare its functional advantage against existing island flaps.
Summary:
- The double-innervated flap, harvested from the index finger's dorsal surface (3-4 cm width), incorporates both dorsal digital nerves.
- It effectively restores tactile sensation to a significant portion of the thumb's prehension area, including the first web space.
Impact:
- This flap offers a superior functional outcome for thumb reconstruction.
- It presents a viable alternative for improving hand function and patient quality of life.
