Function

The longest and strongest bone in the human body. Bears the weight of the body and provides attachment for powerful thigh muscles. Transmits body weight from the hip to the tibia during standing and locomotion.

Clinical Significance

Femoral neck fractures are common in elderly patients with osteoporosis. Femoral shaft fractures result from high-energy trauma. The femoral head is susceptible to avascular necrosis.
