Obturator Internus Muscle

The obturator internus muscle is a critical muscle in the hip region, playing a significant role in stabilizing the hip joint and enabling movements like rotation of the thigh. Disorders affecting this muscle can lead to discomfort, mobility issues, and impact daily activities. This guide provides an in-depth look into obturator internus muscle disorders, including types, causes, symptoms, diagnostic tests, treatments, and more.

The obturator internus muscle is a deep muscle located in the pelvis. It originates from the inner surface of the obturator membrane and surrounding bones and inserts into the greater trochanter of the femur (thigh bone). Its primary function is to rotate the thigh outward (lateral rotation) and stabilize the hip joint.

Types of Obturator Internus Muscle Disorders
