Synovial osteochondromatosis in association with Legg-Calvé-Perthes disease.
A male patient who had had Legg-Calvé-Perthes disease at age 8 years developed synovial osteochondromatosis of the same hip joint 27 years later at age 35. Roentgenographic examination 10 years prior to arthrotomy showed that he had developed 4 loose bodies in the hip and partial disintigration of the fmoral head. The surgical specimens obtained by arthrotomy consisted of 148 loose bodies and suggested that a condition of secondary synovial osteochondromatosis might be differentiated from primary synovial osteochondromatosis.
