Ollier Disease is a rare abnormal development of the bones (skeletal dysplasia) usually beginning in childhood. The disease affects bones and cartilage in joints of the arms and legs. Dwarfism is possible if both sides of the body are affected. Pain is rare in this disease, occurring usually only in case of a fracture. Symptoms Ollier Disease begins gradually, usually during childhood, and is marked by possible shortening of the arms and/or legs. Limping may result from a shortened leg. The head and upper body will be normal. Joint deformities may occur in wrists and/or ankles. A dislocation of the elbow or other joints may occur, possibly causing fractures. This disease may occasionally be associated with some forms of cancer. The abnormal growth of bone end/cartilage areas ceases in time, and calcification may begin after puberty. The bone abnormalities may be in evidence throughout life. Causes The origin of Ollier Disease is unknown at this time. Overgrowth of cartilage cells in certain skeletal and/or joint areas may cause thinning of the external layer (cortex) and distortion of growth in the spongy growth area (metaphysis) of long bones. Affected Population Ollier Disease usually begins in childhood, and may be in evidence later in life. This disease may affect males and females in equal numbers, and can occur worldwide. Related Disorders Exostosis is a hereditary abnormality of bone end/cartilage (epiphyseal) growth inherited as a dominant trait. Although usually without apparent symptoms, pain may be possible due to pressure from benign bone surface growths (exostoses). This is an extremely rare condition, occurring chiefly among Micronesian Islanders. It is most frequent and severe in males. Symptoms may be similar to Ollier Disease, although areas of joint deformity may differ. Maffucci Syndrome is a hereditary genetic disease which may begin between birth and puberty, and is marked by asymmetric distribution of lesions, and abnormal growth of cartilage in one or more long bones. Susceptibility to fractures and skin manifestations are also characteristic of this type of abnormal bone development (skeletal dysplasia). Therapies: Standard Bone grafts have been of benefit to patients with Ollier Disease, as well as surgical treatment of limb length. Fractures usually heal without any follow-up treatment. Prosthetic replacement of the limb may be of benefit in some extreme cases. Therapies: Investigational Research into the causes, as well as orthopedic surgical treatment for Ollier Disease is ongoing. For more information, please see the resources section in this report.
