The "'inferior gluteal nerve "'is the main motor neuron that innervates the gluteus maximus muscle.
12.
The muscle is supplied by the inferior gluteal nerve which arises from the dorsal branches of the ( S2 ) sacral nerves.
13.
There were two to three divisions of the inferior gluteal nerve under the piriformis that would further divide close to the insertion of the nerve into the actual muscle belly.
14.
This determines the name of the vessels and nerves in this region the nerve and vessels that emerge superior to the piriformis are the superior gluteal nerve and superior gluteal vessels.
15.
The superior gluteal nerve passes backward through the greater sciatic foramen, above the piriformis : the inferior gluteal nerve also passes backward through the greater sciatic foramen but below the piriformis ."

17.
There are also a variety of clinical situations leading to local disturbances in the nerve function the positioning of the inferior gluteal nerve makes it vulnerable to iagtrogenic injury during posterior and posterior approaches to the hip
18.
The likelihood of damage to the inferior gluteal nerve is reported to be high when a muscle-splitting incision is made across the gluteus maximus as a part of the classical posterior approach to the hip.
19.
This may cause selective denervation of the gluteus maximus since the inferior gluteal nerve courses along the deep surface of the muscle and is not easily visualized and differentiated from other structures running with it, such as blood vessels.
20.
The posterior approach has been assessed most widely and is perhaps the most frequently used, but it is also the one most likely to be associated with damage to the inferior gluteal nerve since this structure is not usually seen.
