Study Notes
Gluteal Region Anatomy
- The gluteal region consists of the ilium, ischium, and sacrum bones.
Muscles of the Gluteal Region
- The most superficial muscle in the gluteal region is the Gluteus Maximus.
- The small lateral rotators of the thigh are the Gemellus Inferior, Gemellus Superior, Obturator Internus, and Piriformis muscles.
- The Gluteus Medius muscle is paralyzed in a greater trochanter fracture.
- The motor function lost in a greater trochanter fracture is abduction of the thigh.
- Trendelenburg's sign in a greater trochanter fracture is caused by the paralysis of the Gluteus Medius muscle.
Muscle Functions
- The Gluteus Minimus muscle is responsible for stabilizing the pelvis during walking.
- The Gluteus Medius muscle laterally rotates the thigh.
- The Tensor Fascia Latae muscle is responsible for stabilizing the knee joint during extension.
Muscle Nerve Supply
- The Gluteus Minimus muscle is supplied by the Superior Gluteal Nerve.
- The Tensor Fascia Latae muscle is supplied by the Superior Gluteal Nerve.
- The Gluteus Medius muscle is supplied by the Superior Gluteal Nerve.
Muscle Origins and Insertions
- The Gluteus Maximus muscle originates from the gluteal surface of the ilium, lumbar region, and sacrum, and inserts into the gluteal tuberosity of the femur.
- The Gluteus Medius muscle originates from the gluteal surface of the ilium between the anterior and inferior gluteal lines.
- The Gluteus Minimus muscle originates from the gluteal surface of the ilium between the anterior and inferior gluteal lines.
- The Piriformis muscle originates inside the pelvis and enters the gluteal region through the greater sciatic foramen.
Muscle Relationships
- The Gluteus Maximus muscle covers all contents of the gluteal region except the upper lateral part which is superficial.
- The Gluteus Medius muscle is completely covered by the Gluteus Maximus muscle and can be demonstrated by cutting and reflecting the Gluteus Maximus muscle.
- The Tensor Fascia Latae muscle is partially covered by the Gluteus Maximus muscle except for its upper lateral part which is superficial.
