Summary
Modified chimeric perforator flaps effectively reconstruct complex hand defects. This surgical technique offers a viable solution for bone and soft tissue reconstruction, achieving good cosmetic results.
Area of Science:
- Hand surgery
- Microsurgery
- Orthopedic reconstruction
Background:
- Complex hand defects involving bone and soft tissue present significant reconstructive challenges.
- Traditional methods may have limitations in addressing both structural and aesthetic components simultaneously.
Observation:
- A retrospective series of 16 patients with metacarpal or phalanx bone defects underwent reconstruction using modified chimeric radial collateral artery perforator flaps.
- Flaps incorporated skin paddles and humeral bone segments, utilizing independent perforators for vascular supply.
Findings:
- All 16 flaps survived, with successful bone union in all cases within an average of 5.4 months.
- Two instances of postoperative venous congestion were managed successfully with reanastomosis.
- Direct closure of donor sites resulted in linear scars, and cosmetically acceptable outcomes were achieved for most patients.
Implications:
- The modified chimeric radial collateral artery perforator flap is a versatile and effective option for complex hand reconstructions.
- This technique addresses both hard and soft tissue defects, potentially improving functional and aesthetic outcomes in hand surgery.
