The capitellum is the rounded knob on the end of the humerus, and it is held by the radius.<unk>  affects the elbow of the arm. At the elbow, the humerus meets the ulna and the radius. The humerus is the long bone that runs from the shoulder to the elbow, and the ulna and radius are the two bones that make up the forearm. The capitellum is the rounded knob on the end of the humerus and it is held by the radius due to the radius's cup-like shape.<unk>  is part of a family of bone development diseases known as osteochondrosis. In osteochondrosis, the blood supply to an area of developing bone in the dominant elbow is temporarily disrupted by something that is not yet well understood. Therefore, the tissues in the bone are not getting enough blood and they begin to go through necrosis, and they begin to die. Normally, bones grow by the expansion and uniting of the growth plates, but osteochondrosis disrupts this process and the result is cell death and the loss of newly formed tissue. The death of the tissues eventually leads to deterioration of the bone's growth plate. The bone's growth plate is defined as the area at the end of a developing bone where cartilage cells change into bone cells. The bone tissue does regrow, but the necrosis can cause temporary problems in the affected area until the strenuous arm and elbow activity is significantly decreased or stopped for a period of time. It is believed that<unk>  is a precursor to a similar condition called osteochondritis dissecans of the capitellum (OCD). OCD is different from<unk>  because OCD occurs in older children and it does not involve the growth plate because by the time that OCD occurs the growth plates have already fused and the skeleton has finished growing.
