Summary
Functional reconstruction of lower limb ischemic contracture using nerve decompression, tendon transfer, and anastomosis improved patient mobility. These surgical techniques offer a new alternative for treating this severe complication.
Area of Science:
- Orthopedic Surgery
- Reconstructive Surgery
- Lower Limb Biomechanics
Background:
- Ischemic contracture of the lower limb is a severe complication following trauma.
- Established contractures present significant functional deficits.
- Effective treatment strategies are crucial for restoring limb function.
Purpose of the Study:
- To detail the functional reconstruction methods for lower limb ischemic contracture.
- To propose a classification system for ischemic contracture based on severity and prognosis.
Main Methods:
- Surgical reconstruction in 42 patients included nerve decompression, tendon procedures, and nerve anastomosis.
- Procedures were tailored to individual patient's disturbance type and severity.
- Specific techniques included split Achilles tendon transfer and sural-tibial nerve anastomosis.
Main Results:
- All patients achieved ambulation on flat ground post-surgery.
- Drop foot was corrected in 10 patients; 5 experienced residual stair-climbing difficulty.
- Nerve anastomosis resulted in sensory recovery to S2/S3 levels in treated patients.
Conclusions:
- Lower limb ischemic contracture is a devastating post-traumatic complication.
- Prevention remains paramount, but reconstructive surgery offers hope.
- Novel techniques like split Achilles tendon transfer and sural-tibial nerve anastomosis improve functional recovery.
