title: Primary synovial osteochondromatosis presenting as constrictive capsulitis.
abstract: Primary synovial chondromatosis of the joints can present as capsular constriction with peri-articular osteopenia. This rare presentation is highlighted in three cases (two hips and one shoulder). The diagnosis in all the patients was made on arthrography and/or MRI/CT and was confirmed histologically. Synovial chondromatosis should be considered in patients with this presentation. Arthrography is the best imaging modality to confirm the cause (synovial chondromatosis) and effect (constrictive capsulitis).
