Operative Treatment of Primary Synovial Osteochondromatosis of the Hip

Abstract

At a mean of 4.4 years postoperatively, we found that open synovectomy and removal of loose bodies for the treatment of primary synovial osteochondromatosis of the hip is a reliable procedure that can effectively relieve symptoms. Our results also indicated that synovial osteochondromatosis may recur in patients with extensive involvement who are treated with synovectomy alone without dislocation of the hip; however, surgical complications are more likely to occur in patients managed with anterior dislocation of the hip and synovectomy.

A pictorial review of primary synovial osteochondromatosis

“…The second is more extensive and involves synovectomy and nodule removal. There are conflicting reports in the literature as to which is the optimal surgical procedure [26,27,30,31]. If arthroscopic surgery is being considered, it is imperative that PSOC is confined to the joint as the presence of extraarticular disease excludes arthroscopic excision.…”

Extra-articular osteochondromatosis: A collection of four clinical cases of different localization

“…Degenerative osteoarthritis was reported with disintegration of the articular cartilage from multiple intra-articular loose bodies. [10] Routine x rays, show a soft tissue mass with multiple calcified bodies. In extra-articular osteochondromatosis, the mass can be contiguous to a joint or at a variable distance when localized in bursa or tendon sheath.…”

“…17,20 Seguramente la principal complicación de la CS a largo plazo es la progresión degenerativa. 6,16 Todos los casos que presentamos se mantuvieron estables, aunque consideramos que 35 meses de seguimiento promedio es un tiempo insuficiente para establecer conclusiones; igualmente los pacientes intervenidos por CS deben someterse a un examen radiológico periódico para evaluar recurrencias o progresión degenerativa. 16 Reportes, como los de McCarthy 13 en 29 casos, con un seguimiento promedio de 64 meses, comunican un 48% de resultados excelentes, 2 revisiones artroscópicas a los 4 años; 5 pacientes evolucionaron a reemplazo articular, todos tenían lesiones condrales grado III-IV de Outerbridge en el momento de la artroscopia.…”

“…1,3 El tratamiento consiste en la sinovectomía y la extracción de los cuerpos libres. 6 La técnica ideal genera controversia por la recurrencia y la posible progresión degenerativa descrita para técnicas tanto a cielo abierto como artroscópicas. 7 El objetivo de este trabajo es reportar la técnica quirúrgica y los resultados a corto plazo en una serie de pacientes con CS de cadera tratados por vía artroscópica.…”
