Primary synovial osteochondromatosis of hip joint in a teenager

Abstract

Primary synovial osteochondromatosis (PSOC), also known as idiopathic synovial chondromatosis, is a rare benign articular disease with synovial proliferation and metaplasia without any predisposing factor. Clinical and imaging features play a major role in the diagnosis of this condition. We report a case of a young girl presenting with chronic hip pain, and suspected to have PSOC on imaging and confirmed on histopathology. Removal of loose bodies without any creation of surgical femoral dislocation was done as part of her treatment. There was no requirement of synovectomy due to complete synovial destruction secondary to the chronic disease process and such a case has not been reported till date. Patient has completely recovered from her symptoms after surgery.
