A femur fracture is a break in the femur, the longest bone in the human body, located in the thigh. This type of fracture often occurs due to high-impact injuries, such as car accidents or falls. Symptoms typically include severe pain, swelling, and difficulty moving the leg. Treatment for a femur fracture usually involves immobilization with a cast or brace, and in some cases, surgery may be necessary to realign the bone. Recovery can take several weeks to months, depending on the severity of the fracture and the patient's overall health. Physical therapy may also be recommended to restore strength and mobility.
