Gluteus Minimus Muscle Anatomy

Overview
Origin Ilium of the hip (between the anterior and inferior gluteal lines)
Insertion Greater trochanter of femur (anterolateral aspect)
Action Hip abduction
Hip medial rotation
Nerve Superior gluteal nerve (L4, L5, S1)
Artery Superior gluteal artery

Location & Overview

The gluteus minimus muscle is a fan shaped muscle which is deep to the gluteus medius, which is deep to the gluteus maximus. These three muscles are what form the gluteal muscles. However, the gluteus minimus is the smallest of these three muscles. The gluteus minimus’ actions, structure, innervation and blood supply are similar to those of the gluteus medius[1].

Origin & Insertion

The gluteus minimus originates at the ilium (between the anterior and inferior gluteal lines). It then inserts on the greater trochanter of femur (on the anterolateral aspect). Its insertion is anterior to the insertion of the gluteus medius muscle[2].

Here we can see pictured the origin of the gluteus minimus on the ilium. Specifically, between the anterior and inferior gluteal lines.

Here we can see pictured the insertion of the gluteus minimus on the greater trochanter of the femur. Specifically, on the anterolateral aspect of the greater trochanter.

Actions

The main actions of the gluteus minimus muscle are hip abduction and hip medial rotation. It is also involved in stabilising the hip when standing on one leg. The gluteus minimus works closely with the gluteus medius to accomplish these actions [3] [4] [5].

Innervation

The gluteus minimus is innervated by the superior gluteal nerve (L4, L5, S1) [6] [7].

Blood Supply

Blood is supplied to the gluteus minimus by the superior gluteal artery [8].
