A rare case of synovial osteochondromatosis of hip managed with arthroplasty

Abstract

Primary synovial osteochondromatosis of the hip joint is a rare condition. It is characterized by the presence of multiple intra articular loose bodies and can result in mechanical symptoms, even causing degenerative change. Surgical treatment is indicated for synovial osteochondromatosis of the hip joint. However, the optimal approaches for successful surgical management are still controversial. We report a case with primary synovial osteochondromatosis of the hip joint where hip arthroplasty treatment was performed. The posterior approach was used, and total hip replacement was performed. The follow-up duration was 3 months and 6months and one year, respectively. There were no perioperative or post-operative complications. At the latest follow-up, the patients remain symptom free with no radiographic evidence of recurrence. As recurrence rate with arthroscopy, or open excision of chondromatosis is high, and eventually it leads to destruction of joint, total hip arthroplasty achieves the goal for preventing recurrence and provide pain free joint.
