Introduction[edit | edit source]
The gluteal muscles (buttock muscles) are a muscle group consisting of the gluteus maximus (the largest and thereby strongest muscle in the body), gluteus medius, gluteus minimus and tensor fasciae latae muscles. They are found in the gluteal region, an area overlying the posterior aspect of the pelvic girdle and the proximal part of the femur.

Function[edit | edit source]
These muscles help stabilize the upper body and pelvis, aid in locomotion, and extend the hip. The gluteal muscles act on the hip joint, mainly to facilitate abduction and extension of the thigh but some also assist in the adduction, external rotation and internal rotation of the thigh.
- Glut max is an important muscle for activities of daily living, displays of explosive athletic performance, and stability of certain joints in the body. It is as our most powerful hip extensor.
- If the gluteus medius and minimus were not contracting properly, the pelvis would drop towards the opposite side and the trunk would leans towards the opposite side. This is because the gluteus medius and minimus act to stabilize the pelvis eg. in single leg stance, which accounts for 30% of our normal gait cycle. See Trendelenburg Sign.

Physiotherapy Relevance[edit | edit source]
Weak gluteal muscles have been associated with a variety of lower limb issues. It may lead to other muscles or tissues to become overloaded through a cascade of events.eg see below text and links for in depth knowledge
- Patellofemoral pain syndrome
- Gluteal Tendinopathy
- Iliotibial Band Syndrome
- Trochanteric Bursitis
- Greater Trochanteric Pain Syndrome
- Differentiating Buttock Pain - Gluteal Tendinopathy
- Exercise to strengthen the muscles of the gluteus plus exercises to improve core strength result in a greater decrease in low back pain and disability than core strengthening alone.
- Patients with impaired hip abduction may present with an abnormal gait. Impaired hip abduction is commonly due to damage to the superior gluteal nerve. This may occur secondary to pelvic fractures, space-occupying lesions and as a complication of hip surgery. See Trendelenburg’s sign.
Deep Lateral Rotators[edit | edit source]
There are also small, deep muscles in the gluteal region called the "deep lateral rotators" 0r "deep six muscles". These muscles largely act to laterally rotate the femur. They provide stability to the ball and socket joint of the hip. These muscles all originate on the pelvic area and insert onto the greater trochanter of the femur.
The deep lateral rotators muscles are: piriformis; gemellus superior; gemellus inferior; quadratus femoris; obturator internus.
