Neurotomy of the motor branches of tibial nerve innervating the medial gastrocnemius muscle for calf reduction

Objective To evaluate a method to reduce the volume of gastrocnemius muscle for calf reduction. Methods The motor branches of tibial nerves to medial the gastrocnemius muscle were explored and cut off through a 4～5?cm long incision at popliteal crease. The circumference and the shape of the leg were measured and recorded. Results Neurotomy of the nerve to medial the gastrocnemius muscle was performed in 16 cases. After operation, the circumference of the leg was reduced (3.5±1.1?cm averagely) and the curve of the medial line of the calf was reduced. There is no obvious swelling in these cases and the patients were able to walk immediately after operation. The function of the leg was not obviously influenced. Conclusion Neurotomy of the nerve to the medial gastrocnemius muscle was a safe and effective method for calf reduction.
