Pectineus

Pectineus is a muscle that is located in the anterior (front) part of the thigh. It is the most anterior adductor of the hip. The muscle does adduct and medially rotate the thigh but its primary function is hip flexion.

Anatomy

The Pectineus muscle is flat and quadrangular in form, and situated at the anterior (front) part of the upper and medial aspect of the thigh. The pectineus muscle is the most anterior adductor of the hip. The muscle does adduct and medially rotate the thigh but its primary function is hip flexion.

Origin and Insertion

The Pectineus originates from the pecten pubis, which is the portion of the superior ramus of the pubis. It then proceeds almost vertically downward to insert onto the pectineal line of the femur, which is a line on the posterior side of the femur, just inferior to the lesser trochanter.

Function

The Pectineus is one of the muscles primarily responsible for hip flexion. It also carries out adduction and medial rotation of the thigh.

Clinical Significance

Injury to the Pectineus can result in a groin strain, which is a common sports injury. Pain is usually felt in the inner thigh or groin region and can range from mild to severe. Treatment typically involves rest, ice, compression, and elevation (RICE).
