The inferior gluteal nerve branches off the sacral plexus. The nerve's short path primarily serves to innervate the gluteus maximus muscle. The composition of this nerve is from the dorsal branches of the ventral rami of the fifth lumbar and the first two sacral nerves.[1] The inferior gluteal nerve courses inferiorly and medially before exiting the pelvic cavity via the greater sciatic notch. After exiting the notch, the inferior gluteal nerve passes inferior to the piriformis muscle belly before dividing into several muscular branches supplying the gluteus maximus.[2]
