	Gluteus maximus muscle - Wikipedia, the free encyclopedia
		The Gluteus maximus is the largest of the three gluteal muscles.
		One of these, of large size, and generally multilocular, separates it from the greater trochanter; a second, often wanting, is situated on the tuberosity of the ischium; a third is found between the tendon of the muscle and that of the vastus lateralis.
		The gluteus maximus is supplied by the fifth lumbar and first and second sacral nerves through the inferior gluteal nerve.

	Hip Extension and Abduction Dysfunctions
		The muscles involved in the movements are gluteus maximus, gluteus medius, psoas, quadratus lumborum, erector spinae, piriformis, TFL, biceps femoris, adductors and rectus femoris.
		The gluteus maximus is the primary muscle responsible for the motion of hip extension.
		The gluteus medius muscle is the primary muscle responsible for hip abduction.

		By retracting the rectus femoris muscle medially, the perforators are traced to the descending branch of the lateral femoral cutaneous artery and venae comitantes.
		The gracilis muscle is innervated by the anterior branch of the obturator nerve (L2-L4).
		The nerve to the adductor longus muscle and the medial cutaneous nerve of the thigh are identified on the deep surface of the adductor longus muscle.

		The sartorius muscle forms the outer boundary of the triangle, and may be traced from the anterior superior spine obliquely downward and inward, across the front of the thigh, to the inner side of the knee.
		The two vasti muscles are well marked, the internal being the lower and forming with the sartorius the rounded bulging above the inner side of the knee.
		The rounded mass of the buttock is formed by the gluteus maximus muscle covered by fat; the lower horizontal boundary is called the fold of the nates, and does not correspond exactly to the lower edge of the muscle.

		Gluteus maximus is a powerful extensor of the hip joint and contributes to lateral rotation.
		Gluteus maximus is innervated by the inferior gluteal nerve.
		The upper outer quadrant of the gluteus maximus is used to avoid injury to the sciatic nerve.

	Gluteus maximus muscle, lower back pain problems and sports injury prevention (Site not responding. Last check: 2007-11-06)
		The EMG activity of the gluteus maximus, biceps femoris and paraspinal muscles was recorded during the whole of the movement.
		During flexion gluteus maximus activity was significantly shorter and during extension the gluteus maximus activity ended earlier.
		This means that the gluteus maximus of the back patients was switching on later and turning off sooner during the flexion extension movement.

		The insertion of the superior portion of the gluteus maximus muscle is the iliotibial; this insertion is released.
		The medial edge of the origin of the gluteus maximus is elevated in a medial-to-lateral direction for approximately 4 cm because the superior and inferior gluteal arteries enter the gluteus muscle 5 cm from its origin.
		In using the superior portion of the gluteus maximus muscle as a flap, it is elevated in a lateral-to-medial direction to avoid injury to the superior gluteal artery, which can be difficult to identify from the medial direction because of the inflammation and scarring from the sacral pressure sore.

	Gluteus Maximus (Site not responding. Last check: 2007-11-06)
		Origin: The medial crest of the ilium, the inferior lateral angle of the sacrum, the aponeurosis of the erector spinae muscle, the sacro-tuberous ligament, the side of the coccyx and the fascia covering the gluteus medius.
		The fingers (the thumbs may be used here because of tissue density) are rolled (a light smooth pressure) over the surface of the gluteus maximus near its origin, angling along the plane of the inferior lateral angle, approxfmately half an inch to an inch from the sacrum.
		The gluteus maximus is also working for correction of the deviated sacral "angle," as the inferiorly misaligned sacrum shifts the "angle" closer toward the median line.

		The sciatic nerve runs deep to the pyriformis muscle (inferior to gluteus medius muscle), and at the inferior edge of the pyriformis muscle and medial to the midline of the buttock, the nerve becomes more superficial but deep to the gluteus maximus muscle just superior to the ischial tuberosity.
		After having the prosthesis placed over the gluteus maximus muscle by another physician, one patient with a very thin fat pad was displeased because the margins of the prosthesis were noticeable thought the skin, and there was sagging.
		Although the implants are placed under the gluteus maximus muscle, if the inferior portion of the gluteus maximus muscle, if the inferior protiuon of the implant is lateral to the midline of the buttock, there should be no problem of sciatic nreve irritation.

		The gluteus maximus muscle-splitting myocutaneous flap for treatment of sacral and coccygeal pressure ulcers.
		The advantages of this technique include reduced blood loss, preservation of most of the gluteus maximus for future use, and retained function of the gluteus maximus for stair climbing and single-limb support in the ambulatory patient.
		We recommend the gluteus maximus muscle-splitting myocutaneous flap as the procedure of choice for closure of small low sacral or coccygeal ulcers in both the ambulatory and nonambulatory patient.

		The gluteus maximus is the largest skeletal muscle in the human body.
		This shortening over time will mechanically limit the hip extension capabilities of the gluteus maximus muscle, but it will also neurologically inhibit (via reciprocal inhibition) proper function and contraction of the gluteus maximus muscle.
		A possible therapeutic intervention could include lengthening of shortened muscles, particularly the iliopsoas and pectoralis group, and other muscles shortened as a result of this habitual posture.
