Distal Radioulnar Joint Synovial Osteochondromatosis - A Case Report and Review of Literature

Synovial chondromatosis is a rare benign clinical condition, with a rare location in the wrist. This study presents a case of synovial chondromatosis in the distal radioulnar joint (DRUJ) treated successfully with surgical excision. A 45-year old right handed male presented in our department, with a 3-year history of wrist pain, without any trauma. He referred a lump around the right DRUJ which fluctuated in size associated with frequent pain, weakness and a popping with occasional locking of the wrist. Clinical examination showed a painful lobulated swelling over right DRUJ with a crepitus at the lateral stress of the joint. X-rays and MRI showed multiple coarse calcific densities around the DRUJ. The patient was treated with surgical removal of calcified loose bodies originated by the DRUJ. Biopsy results were consistent with synovial chondromatosis. One year postoperatively, patient was pain-free, with a full range of motion and no signs of local recurrence.
