Reconstructive procedures for extremities with peripheral nerve defects.

Surgeons who undertake reconstruction of extremities with peripheral nerve loss should be experienced enough to select the appropriate procedures for the individual patient. To gain adequate strength for a specific function, a new muscle-tendon unit usually is added to the power-train rather than redistribute muscles that have related function. Precise sensibility required precise motion, which is very difficult to achieve following peripheral nerve loss. The anticipated result should be a balanced simplification of motor and sensory function.
