Summary
A modified second dorsal metacarpal artery flap successfully repaired thumb defects in seven patients. This technique offers a viable reconstructive option when other local flaps are unavailable.
Area of Science:
- Hand surgery
- Reconstructive surgery
- Microsurgery
Background:
- Thumb defects pose reconstructive challenges.
- Limited availability of local flaps for thumb reconstruction.
Observation:
- A modified flap, pedicled with the second dorsal metacarpal artery, was utilized.
- Flap sizes ranged from 1 cm x 3 cm to 2 cm x 4 cm with a 6-7 cm vascular pedicle.
- Seven thumb wounds were treated with this flap.
Findings:
- All seven flaps survived post-operatively.
- Satisfactory reconstructive results were achieved in all cases.
Implications:
- This modified flap provides a valuable alternative for thumb defect repair.
- It is particularly useful when index or middle finger island flaps are not feasible.
