Case Discussion

Trevor disease usually presents in in childhood. Can affect the upper or lower limbs, but usually affects the lower limb ankle or knee. It is a disorder of epiphyseal osetocartilaginous growth, characterised by osteochondromas of the epiphysis of long bones. Presents as an irregular lesion rising from the affected epiphysis, and then gradually calcification centres develop, when it ossifies becomes confluent with the underlying bone 1-3. Early treatment can help prevent osteoarthritis.
