Pectineal Line (Femur)[edit]
The pectineal line of the femur is a ridge on the posterior surface of the femur, which serves as an important anatomical landmark. It is located on the upper part of the shaft of the femur, running from the base of the lesser trochanter to the linea aspera.
Anatomy[edit]
The pectineal line is a prominent ridge that provides attachment for the pectineus muscle. It is situated below the lesser trochanter and extends downward and medially to merge with the linea aspera, a rough line that runs along the posterior aspect of the femur.
Location[edit]
The pectineal line is found on the posterior surface of the femur, specifically on the proximal part of the shaft. It is positioned between the lesser trochanter and the linea aspera.
Function[edit]
The primary function of the pectineal line is to serve as an attachment site for the pectineus muscle, which is involved in hip flexion and adduction. The pectineus muscle originates from the superior ramus of the pubis and inserts onto the pectineal line of the femur.
Clinical Significance[edit]
The pectineal line is an important landmark in orthopedic surgery and radiology. It is often used as a reference point in procedures involving the proximal femur. Injuries or abnormalities in this area can affect the function of the pectineus muscle and may lead to difficulties in hip movement.
