Adductor longus muscle

Adductor Longus Muscle

The Adductor Longus is a key muscle located in the thigh that plays a crucial role in the movement of the lower limb. It is one of the muscles that make up the medial compartment of the thigh, primarily involved in the adduction of the thigh at the hip joint. This muscle is significant not only for its function in movement but also for its role in stabilizing the pelvis during locomotion.

Anatomy

The Adductor Longus originates from the pubis near the pubic symphysis, making it one of the more anteriorly located adductors of the thigh. It extends inferomedially, inserting into the middle third of the linea aspera on the femur. Its proximity to the femoral artery and femoral nerve is clinically significant, as it can be a landmark in various medical procedures.

Innervation

The Adductor Longus is innervated by the obturator nerve (L2, L3), which originates from the lumbar plexus. This nerve supplies the muscle, enabling it to perform its primary function of adduction.

Blood Supply

Blood supply to the Adductor Longus is primarily through the obturator artery, a branch of the internal iliac artery. This ensures the muscle receives the necessary nutrients and oxygen for its function.

Function

The primary function of the Adductor Longus is to adduct the thigh at the hip joint. This action is crucial for movements such as crossing one's legs or stabilizing the pelvis during walking or running. Additionally, the Adductor Longus assists in the medial rotation and flexion of the thigh, contributing to various movements and activities.

Clinical Significance

1. 1. 1. Adductor Strain###

The Adductor Longus is susceptible to strain, particularly in athletes who engage in sports requiring sudden changes in direction or intense physical activity. Symptoms include pain and tenderness along the inner thigh, and treatment typically involves rest, ice, and physical therapy.

1. 1. 1. Adductor Longus Tendinopathy###

Chronic overuse of the Adductor Longus can lead to tendinopathy, characterized by pain and swelling in the tendon area. Management includes rest, anti-inflammatory medications, and rehabilitation exercises.
