This study presents a successful cross-extremity hand replantation using a novel nerve repair technique. Favorable functional recovery was achieved in a patient with severe bilateral limb injuries.
Area of Science:
- Reconstructive surgery
- Microsurgery
- Trauma surgery
Background:
- Severe bilateral upper extremity trauma presents significant reconstructive challenges.
- Orthotopic replantation is not always feasible in cases of extensive, asymmetrical injuries.
Observation:
- A 40-year-old female sustained a right arm avulsion and irreparable left wrist/hand injury.
- The patient underwent a cross-extremity replantation: right forearm to left forearm stump.
Findings:
- A novel nerve repair strategy was employed for the cross-replanted hand.
- Favorable functional recovery of the replanted hand was observed post-operatively.
Implications:
- Cross-extremity replantation is a viable option for specific cases of bilateral amputations.
- This technique offers hope for limb salvage when standard replantation is impossible.
