S72.4: Fracture of lower end of femur

A fracture of the lower end of the femur refers to a break or crack in the lower part of the thigh bone, which is the longest and strongest bone in the human body. This type of injury is typically due to high energy impact, such as that sustained during traffic accidents, sports activities, or falls in older individuals with weakened bones. Symptoms often include significant pain, swelling, bruising, and inability to move the affected leg. The injury can severely affect the knee joint, which lies at the lower end of the femur, and disrupt its function. Dependence on this joint for walking and weight-bearing makes this such fracture a serious injury with the potential to impose long-term physical impairment if not properly treated.
