Summary
Free vascularized toe joint transfer effectively reconstructs severe hand injuries, restoring function. This innovative technique addresses complex metacarpophalangeal joint damage by transplanting toe joints.
Area of Science:
- Hand surgery
- Orthopedic surgery
- Microsurgery
Background:
- Metacarpophalangeal joint dysfunction significantly impairs hand function.
- Simultaneous reconstruction of multiple hand structures in complex injuries is challenging.
- Free vascularized autogenous toe joint transplantation offers a comprehensive solution.
Observation:
- Two patients with acute complex hand injuries underwent toe joint transfer.
- The second toe's metatarsophalangeal joint was used to replace finger metacarpophalangeal joints.
- This procedure addressed deficits in soft tissue, extensor mechanism, joint, and flexor tendon.
Findings:
- Successful reconstruction of metacarpophalangeal joint function was achieved.
- The transferred toe joints provided essential soft tissue, extensor, and flexor components.
- Postoperative follow-up at 16 and 8 months demonstrated positive outcomes.
Implications:
- Free vascularized toe joint transfer is a viable and effective option for severe hand injuries.
- This technique can restore complex joint function and improve patient quality of life.
- Further research can explore broader applications in reconstructive surgery.
