Caption = The gluteus minimus and nearby muscles
Caption2 = Structures surrounding right hip-joint. (Gluteus minimus visible at center left.)
Origin = Gluteal surface of ilium, undergluteus medius .
Insertion =Greater trochanter of thefemur
Blood =superior gluteal artery
Nerve =superior gluteal nerve (L4, L5, S1 nerve roots)
Action = Works in concert with gluteus medius: abduction of the hip; preventing adduction of the hip. Medial rotation of thigh.
Antagonist =lateral rotator group The gluteus minimus (or glutæus minimus), the smallest of the threegluteal muscles , is situated immediately beneath thegluteus medius .Origin and insertion
It is fan-shaped, arising from the outer surface of the ilium, between the anterior and inferior
gluteal lines , and behind, from the margin of thegreater sciatic notch .The fibers converge to the deep surface of a radiated aponeurosis, and this ends in a tendon which is inserted into an impression on the anterior border of the
greater trochanter , and gives an expansion to the capsule of the hip joint.Relations
A bursa is interposed between the
tendon and the greater trochanter.Between the
gluteus medius and gluteus minimus are the deep branches of the superior gluteal vessels and thesuperior gluteal nerve .The deep surface of the gluteus minimus is in relation with the reflected tendon of the
rectus femoris and the capsule of the hip joint.Action
The gluteus medius and gluteus minimus abduct the thigh, when the limb is extended, and are principally called into action in supporting the body on one limb, in conjunction with the
Tensor fasciæ latæ .Their anterior fibers, by drawing the greater trochanter forward, rotate the thigh inward, in which action they are also assisted by the Tensor fasciæ latæ.
Variations
The muscle may be divided into an anterior and a posterior part, or it may send slips to the
piriformis , thesuperior gemellus or the outer part of the origin of thevastus lateralis .The Nutty Professor (1996 film) uses the words "gluteus minimus" as a buzzword for a "nice ass".ee also
