Summary
Free-functioning muscle transfers (FFMTs) are effective for restoring motor function after major upper limb replantation. This study reviewed their use in 16 patients, highlighting their role in complex reconstructions.
Area of Science:
- Orthopedic Surgery
- Reconstructive Microsurgery
- Upper Extremity Reconstruction
Background:
- Major upper limb replantation is complex, often needing secondary procedures for optimal function.
- Loss of critical forearm muscles was a contraindication for replantation.
- Free-functioning muscle transfers (FFMTs) have expanded replantation possibilities.
Purpose of the Study:
- To review indications for FFMTs in major upper limb replantation.
- To discuss surgical considerations for FFMTs post-replantation.
- To evaluate outcomes of FFMTs after upper limb replantation.
Main Methods:
- Retrospective study of patients undergoing forearm or proximal upper limb replantation.
- Inclusion of patients who subsequently received FFMTs for motor function reconstruction.
- Data collected from 1998 to 2022.
Main Results:
- 16 patients received 20 FFMTs for finger flexion/extension reconstruction.
- All patients underwent additional secondary procedures.
- FFMTs were utilized to restore critical muscle function.
Conclusions:
- Free-functioning muscle transfers are valuable for restoring motor function after major upper limb replantation.
- FFMTs expand reconstructive options in complex cases.
- Secondary procedures complement FFMTs for enhanced outcomes.
