Obturator Internus Muscle Lesions

The obturator internus muscle is a crucial component of the pelvic region, playing a significant role in hip movement and stability. When this muscle becomes injured or affected by lesions, it can lead to a range of symptoms and complications. This article provides a comprehensive overview of obturator internus muscle lesions, including their types, causes, symptoms, diagnostic tests, treatments, medications, surgeries, prevention strategies, and guidance on when to see a doctor. Written in simple language, this guide is designed to be accessible and informative for readers and search engines alike.

The obturator internus muscle is a flat, triangular muscle located in the pelvic region. It originates from the inner surface of the obturator membrane and the surrounding bones of the pelvis and inserts into the greater trochanter of the femur (thigh bone). Its primary function is to help rotate the thigh outward (external rotation) and stabilize the hip joint. It also plays a role in the movement of the lower limb.

A lesion refers to any abnormal tissue or damage in a specific area, and in the context of the obturator internus muscle, it can refer to a variety of issues, including tears, strains, or inflammation. These lesions can result from trauma, overuse, or underlying medical conditions.

Types of Obturator Internus Muscle Lesions
