Enchondroses Ollier disease is a rare skeletal disorder
characterized by abnormal bone development (skeletal dysplasia).
While this disorder may be present at birth (congenital); it may
not become apparent until early childhood when symptoms, such as
deformities or improper limb growth, are more obvious. Ollier
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

long bones of the legs and arm
