Name

• Gluteal Muscle Group
• Gluteal Muscles
• Glutes
• Buttocks

General

• Group of 3 muscles which make up the gluteal region, commonly called the buttocks
• All 3 muscles originate from the ilium, sacrum and insert on the femur
• They participate in extension, abduction, external rotation, internal rotation of the hip joint

Gluteus Maximus

• Origin: gluteal surface of the ilium
• Insertion: greater trochanter, gluteal tuberosity

Gluteus Medius

• Origin: between iliac crest, gluteal line, deep to gluteus maximus
• Insertion: oblique ridge of the lateral greater trochanter

Gluteus Minimus

• Origin: lateral aspect of ilium, deep to gluteus medius
• Insertion: anterior surface of greater trochanter

Vascular Supply

• Superior Gluteal Artery
• Inferior Gluteal Artery

Innervation

• Superior Gluteal Nerve
• Inferior Gluteal Nerve

Actions at the Hip Joint

• Extension
• Abduction
• External rotation
• Internal rotation

Clinical Significance
