Endochrmatosis

The term enchondromatosis refers to multiple enchondromas (islands of cartilaginous tissue in the metaphyses of tubular bones) that retard growth and deform the bone.

 * affected long bones shortened and bent, enlarged metaphyses
 * fingers enlarged and deformed in the hands, pseudomadelung's deformity on the forearm (see Madelung's deformity), genu valgum

 * removal of symptomatic enchondromas, spongioplasty
