Pectineal Line (Femur)

The pectineal line is a prominent ridge located on the anterior surface of the femur, a long bone in the human body. It serves as an attachment site for several muscles and ligaments.

Anatomy

The pectineal line is a bony ridge that extends from the lesser trochanter to the linea aspera on the medial surface of the femur. It is located on the proximal third of the femur, just below the lesser trochanter. The line is named after its proximity to the pectineus muscle, which attaches to it.

Function

The pectineal line serves as an attachment site for various muscles and ligaments involved in hip and thigh movements. Some of the muscles that attach to the pectineal line include:

• Pectineus muscle
• Iliopsoas muscle
• Adductor longus muscle
• Adductor brevis muscle

These muscles play a crucial role in flexion, adduction, and rotation of the hip joint.

Clinical Significance

In some cases, the pectineal line can be a site of stress fractures, especially in athletes or individuals who engage in repetitive activities that put strain on the hip and thigh muscles. Stress fractures can cause pain and limit mobility. Proper diagnosis and treatment are essential to prevent further complications.
