what are some diseases the femur have?

The femur can be affected by several diseases, including osteoporosis, which weakens bones and increases fracture risk; osteosarcoma, a type of bone cancer that can occur in the femur; and avascular necrosis, where blood supply to the bone is compromised, leading to bone death. Additionally, fractures due to trauma or falls are common, especially in older adults with weakened bones. Other conditions such as Paget's disease can also affect the femur, causing abnormal bone remodeling.
