Metaphyseal chondrodysplasia (MCD) is a relatively rare hereditary disease of the skeletal system, in which disproportionate dwarfism sparing the trunk is noted. Among the four subtypes of MCD, the Schmid type is relatively common and shows minimal clinical abnormalities. We report a boy, diagnosed to have MCD, Schmid type, and who was followed-up for 17 years until skeletal maturity, during this period he underwent proximal femoral valgus osteotomies as well as tibial deformity correction with lengthening and femoral lengthening procedures.
