Ollier’s Disease – Multiple Enchondromas
Ollier’s disease primarily affects the long bones and cartilage of the joints of the arms and legs, specifically the area where the shaft and head of a long bone meet (metaphyses). The pelvis is often involved; and even more rarely, the ribs,
The pelvis is often involved; and even more rarely, the ribs, breastbone (sternum), and/or skull may also be affected. Ollier’s disease manifests as greater than normal growth of the cartilage in the long bones of the legs and arms so that growth is abnormal and the outer layer (cortical bone) of the bone becomes thin and more fragile.
These masses of cartilage are benign (non-cancerous) tumors known as enchondromas.
