Synovial Chondromatosis of Hip Joint in a Patient with Ankylosing Spondylitis: A Case Report

Abstract

Synovial chondromatosis in association with ankylosing spondylitis is extremely rare and has been reported only once before and this case report is presenting a similar case. The knee is the preferential site of involvement with involvement of the hip being reported sparsely. We herein report a case of a 52-year-old male who came with complaints of the lower back pain for 5 years and left hip pain for 1.5 years who was diagnosed with synovial chondromatosis of the hip joint with axial ankylosing spondylitis and was managed operatively. We here review briefly the clinical manifestations, pathogenesis, diagnosis, previously reported cases as well as treatment of synovial chondromatosis in patients with immune-mediated inflammatory arthritides. There should be a high index of suspicion to diagnose synovial chondromatosis in association with inflammatory arthritides. We also believe that surgical management is an effective method of treatment of an established synovial
chondromatosis of the hip joint.
