| The gluteus medius is one of three gluteal muscles (minimus, medius and maximus). It is a superficial, fan shaped and broad muscle that lies in the posterolateral aspect of the pelvis, inferior to the iliac crest.<ref name="Palastanga et al, 2002">Palastanga N, Field D, Soames R. Anatomy and Human Movement, Structure and Function. 4th ed. Edinburgh: Butterworth Heinemann; 2002.</ref> The gluteus medius has a broad origin on the external (gluteal) ilium and its tendon inserts into the lateral aspect of the greater trochanter.<ref name="Drake et al, 2010">Drake RL, Vogl AW, Mitchell, AWM. Gray's Anatomy for Students. 2nd ed. Philadelphia: Churchill Livingstone; 2010.</ref> The muscle is overlapped by the gluteus maximus and covered with a strong layer of fascia.<ref name="Palastanga et al, 2002" /><br>

| '''Origin: '''External (gluteal) surface of ilium between anterior and posterior gluteal lines.<ref name="Palastanga et al, 2002" /> Reaches from iliac crest superiorly and as far as the sciatic notch inferiorly.<ref name="Palastanga et al, 2002" /> Superficial to gluteus maximus.<ref name="Drake et al, 2010" /><br>
| |
| | |
| '''Insertion: '''Lateral surface of greater trochanter.<ref name="Drake et al, 2010" /> A bursa seperates the tendon from the greater trochanter. <ref>Diop M, Parratte B, Tatu L, Vuillier F, Faure A, Monnier G. Anatomical bases of superior gluteal nerve entrapment syndrome in the piriformis foramen. Surg Radiol Anat 2002; 24: 155-9.</ref>

| '''Nerve: '''The Superior Gluteal Nerve (SGN) supplies the gluteus medius. The SGN originates at the sacral plexus at levels L4, L5 & S1.<ref name="Kenny et al, 1999" /> The SGN divides into several branches, supplying both the gluteus medius and minimus as it passes horizontally between them both. <ref name="Kenny et al, 1999">Kenny P, O’Brien CP, Synnott K, Walsh MG. Damage to the superior gluteal nerve after two different approaches to the hip. J Bone Joint Surg Br 1999; 81: 979-81.</ref> The nerve terminates where it supplies the tensor facsia latae. <ref name="Kenny et al, 1999" /><br>
| |
| | |
| The area of skin covering the gluteus medius is supplied by dermatome at levels L1 & L2.<ref name="Palastanga et al, 2002" />

| | |
| '''Blood Supply:''' Superior gluteal artery and superior gluteal vein.<ref name="Drake et al, 2010" /> <br>
