Synovial osteochondromatosis of the wrist joint: A case report

Abstract

Abstract. Synovial osteochondromatosis is a rare condition in which multiple cartilaginous nodules proliferate within the synovial membranes of joints, tendon sheaths or bursae. In general, a complete synovectomy is an effective method to treat this disease. Commonly involved joints are the knee, glenohumeral joint, elbow, hip and ankle, although any articulation may be affected. However, synovial osteochondromatosis occurs rarely in the wrist, and there have been a lack of reports of this occurrence in the literature. The current study presents a case of synovial osteochondromatosis in a 33-year-old man, who was admitted in 2014 with the symptom of swelling of the left wrist joint for 2 years. The swelling had become increasingly painful over the previous 2 months. Physical examination revealed local tenderness and a soft pliable mass, with no involvement of the skin and with moderate pain. X-ray, computed tomography and magnetic resonance imaging of the left wrist revealed a lump at the volar radial side of the left wrist joint without any bone erosion. The lesion was subsequently excised. Histological examination resulted in a diagnosis of osteochondromatosis, which was not considered prior to the surgery. The present case was reported with the aim of analyzing the clinical, imaging characteristic and therapeutic modalities of synovial osteochondromatosis of the wrist. While there was no evidence of recurrence for the subsequent 4 months of post-operative follow-up in the present case, the long-term efficacy of surgical excision requires extended observation.

Excision of 93 loose bodies of synovial osteochondromatosis in the left ankle: a case report

“…3 It is characterized by multiple cartilaginous nodules within the synovial or tenosynovial membrane. 4 It is present in males twice as often in females, usually in the third to fifth decades of life. 5 Synovial osteochondromatosis is originating from chondrocyte metaplasia within the synovium, forming interarticular and extraarticular pedunculated cartilage.…”

Synovial Osteochondromatosis at the Carpometacarpal Joint of the Thumb

“…Symptoms of SOC are nonspecific, including a palpable mass, swelling, pain, tenderness, and restricted movement of the joint [ 1 , 4 ]. Complications of SOC include secondary degenerative osteoarthritis [ 3 ].…”

“…Synovial osteochondromatosis (SOC) is a benign neoplasm characteristic of synovial connective tissue metaplasia within the synovial membranes of joints, tendon sheaths, or bursae [ 1 – 3 ]. SOC commonly affects all major joints including the knee, followed by the hip, elbow, wrist, ankle, and shoulder joints [ 1 , 4 , 5 ]. SOC in the hand is rare.…”

Synovial Chondromatosis in the Metacarpophalangeal Joint

“…6,7 The typical clinical presentation is pain and decreased ROM with joint swelling or effusion. [8][9][10][11][12] The cartilaginous tissue present within the joint may also detach and form loose bodies that can undergo calcification and ossification. 1 The origin may be extra-articular or intra-articular.…”

“…16 Synovial chondromatosis has a bimodal presentation, seen more commonly in males aged 30 to 50 years and becoming female dominant in later years. 1,8,10,12,13,17 This condition can be subdivided into primary and secondary, with secondary being due to another process affecting the joint such as degeneration or trauma. Milgram described a type of classification of SC in which early, intermediate, or late stages were described, depending on the presence of synovial disease and loose bodies.…”
