Nerve Injury and Entrapment in the Lower Extremity
The lower limb is innervated by the lumbar plexus and the sacral plexus. The lumbar plexus consists of L2, L3, and L4, which divide to form the lateral cutaneous nerve of the thigh, the femoral nerve, and the obturator nerve. The sacral plexus consists of L4, L5, S1, S2, and S3 and forms the sciatic nerve (Fig. 1).
