Detailed information on the anatomy of human bones and the most common bone disorders, including avascular necrosis, fibrous dysplasia, osteogenesis imperfecta, osteomyelitis, Paget's disease of the bone, primary hyperparathyroidism, bone cancer, chondros

Paget disease of the bone is a chronic bone disorder. It causes bones to become enlarged and deformed. Bone may become dense, but fragile, because of excessive breakdown and deformation of bone. The disease is the most common bone disorder after osteoporosis in people older than age 50.

Primary hyperparathyroidism is when one or more of the parathyroid glands makes too much parathyroid hormone. This can lead to bone tissue loss. Here's what you need to know.

Giant cell tumor of bone is a rare, fast-growing noncancer tumor. It often grows near a joint at the end of a bone. Read on to learn about symptoms, diagnosis, and treatment.

Fibrous dysplasia is a chronic disorder in which an abnormal development of fibrous tissue causes bones to expand. Any bone can be affected. More than one bone can be affected at any one time, and, when multiple bones are affected, it is not unusual for them to all be on one side of the body. However, fibrous dysplasia does not spread from one bone to another.

An enchondroma is a type of noncancerous bone tumor that begins in cartilage. An enchondroma most often affects the cartilage that lines the inside of the bones. It often affects the tiny long bones of the hands and feet. It may also affect other bones such as the femur (thighbone), humerus (upper arm bone), or tibia (one of the two lower leg bones).
