Two Cases; Extra-articular Synovial Chondromatosis of Flexor Compartments of the Wrist

Abstract

Synovial chondromatosis is a benign synovial neoplasm. Its main characteristic is the formation of cartilaginous nodules in synovial joints,bursae and tendon sheath. It usually presents between the third and fifth decades. The most affected joints are knees, hips, elbow andshoulders; it usually affects only one joint. Patients usually complain of painless mass or swelling, and also reduced range of motion orjoint blockage. We present two cases of extra-articular involvement of synovial chondromatosis in the flexor compartments of the wrist.
