Femur Bone – Posterior Markings

Bone Markings:

[posterior view / right femur]:

  1. image descriptionShaft (Corpus femoris) is the cylindrical, anteriorly arched body of the femur.

  1. image descriptionHead (Caput femoris) is a large, smooth, ball-shaped structure on the proximal end of the bone. It fits into the socket (acetabulum) of the of the hip at the hip joint.

  1. image descriptionFovea of the femur head (Fovea capitis femoris) is a small, pit-like depression on the medial surface of the head. It is an attachment site for the ligamentum teres (round ligament or ligament of head of the femur). This short, narrow, ligamentous band transmits arteries to the head of the femur and helps attach the head to the acetabulum of the os coxae (hip bone).

  1. image descriptionNeck (Collum femoris) is a pyramid-shaped expanse that connects the head of the femur to the shaft. it extends laterally from the head at a downward angle of approximately 125 degrees and is a frequent site of fractures.

  1. image descriptionGreater trochanter (Trochanter major) is a large, irregular-shaped process located lateral to the neck and superior to the shaft. It is an attachment point for the gluteus medius, gluteus minimus, piriformis, obturator, and gemellus muscles.

  1. image descriptionLesser trochanter (Trochanter minor) is a medial prominence located just inferior to the neck. It is the insertion point for the iliacus and psoas major muscles.
Femur bone
Lesser trochanter - Femur bone

  1. image descriptionIntertrochanteric crest (Crista intertrochanterica) is a thick ridge that runs obliquely along the base of the posterior neck from the greater trochanter to the lesser trochanter. It marks the junction between the neck and shaft.

  1. image descriptionQuadrate tubercle (Tuberculum quadratum) is a small elevation on the intertrochanteric crest that serves as an attachment point for quadratus femoris muscle.

  1. image descriptionPectineal line (Linea pectinea) is a slight ridge located inferior to the posterior surface of the lesser trochanter. It is an inferior (distal) attachment site for the pectineus muscle.

  1. image descriptionLinea aspera (Linea aspera) is a vertical ridge that runs along the midline of the femur’s posterior surface. The medial and lateral lips of the linea aspera are attachment sites for the adductor, vastus lateralis, vastus medialis, and biceps femoris (short head) muscles.

  1. image descriptionGluteal tuberosity (Tuberositas glutea) is a roughened, vertical elevation that extends from the top of the linea aspera to the base of the greater trochanter. It is an insertion point for the gluteus maximus muscle.

  1. image descriptionMedial condyle (Condylus medialis) is a large rounded projection at the mediodistal end of the bone. It articulates with medial condyle of the tibia at the knee joint.

  1. image descriptionIntercondylar fossa (Fossa intercondylaris) is a large notch between the posterior condyles that provides space for the cruciate ligaments that help attach the femur to the tibia at the knee.

  1. image descriptionMedial epicondyle (Epicondylus medialis) is a protrusion above the medial condyle. It is an attachment point for the tibial (medial) collateral ligament that helps attach the femur to the tibia at the knee.

  1. image descriptionAdductor tubercle (Tuberculum adductorium) is a small elevation on the superior surface of the medial condyle. The vertical fibers of the adductor magnus muscle attach to this prominence.

  1. image descriptionLateral epicondyle (Epicondylus lateralis) is a small protrusion above the lateral condyle. It is an attachment point for the fibular (lateral) collateral ligament that helps attach the femur to the tibia at the knee.

  1. image descriptionLateral supracondylar line (Linea supracondylaris lateralis) is an inferior extension of the lateral lip of the linea aspera that ends at the lateral epicondyle. The ridge is an attachment site for the vastus lateralis, piriformis, and biceps femoris (short head) muscles.

  1. image descriptionMedial supracondylar line (Linea supracondylaris medialis) is an inferior extension of the medial lip of the linea aspera that terminates just above the adductor tubercle. It serves as attachment point for inferior portions of vastus medialis and adductor magnus muscles.
