Summary
This study presents a novel surgical technique for common peroneal nerve paralysis. Transposing the gastrocnemius muscle restored active foot dorsiflexion and enabled automatic walking in patients.
Area of Science:
- Orthopedic Surgery
- Neuroscience
- Reconstructive Surgery
Background:
- Persistent traumatic paralysis of the common peroneal nerve often requires tendon transfer surgery.
- Existing methods utilize antagonist muscles, which can be less effective for restoring natural foot function.
Observation:
- A new surgical approach involves transposing the lateral head of the gastrocnemius muscle.
- The deep branch of the peroneal nerve was coapted to the motor branch of the tibial nerve innervating the gastrocnemius.
Findings:
- Successful nerve regeneration and neurotization allowed the transposed gastrocnemius to reinnervate.
- The gastrocnemius muscle effectively took over the function of the paralyzed muscles, enabling voluntary dorsiflexion.
- The procedure resulted in automatic walking in all 6 cases studied.
Implications:
- This technique offers a promising alternative for treating common peroneal nerve injuries.
- It provides a more functional restoration of foot movement compared to traditional tendon transfers.
- Further research can explore long-term outcomes and broader applications of this surgical innovation.
