Extra Quality: Abductor Longus Muscle

The is a clinical test for abductor weakness. The patient stands on one leg; if the contralateral pelvis drops, the test is positive. A positive sign indicates dysfunction of the abductor longus, medius, and/or minimus, often due to superior gluteal nerve injury, hip fracture, or osteoarthritis. In gait, this presents as a Trendelenburg gait (ipsilateral trunk lean during stance).

The abductor longus is a skeletal muscle located in the lateral compartment of the thigh. As its name implies— abductor (to draw away from the midline), longus (long)—it is a primary abductor of the hip joint and one of the three gluteal abductors, alongside the gluteus medius and gluteus minimus. Despite being less commonly discussed than the gluteus medius, the abductor longus plays a critical role in lower limb biomechanics, pelvic stability during gait, and the pathogenesis of several common musculoskeletal disorders. This essay provides a comprehensive overview of the abductor longus, covering its gross anatomy, innervation, blood supply, functional role, and clinical relevance. abductor longus muscle
