Diagnosis of Synovial Chondromatosis of Temporomandibular Joint: Case Report and Literature Review.

Healthcare (Basel) 2021 May 18;9(5). Epub 2021 May 18.

School of Dental Medicine, Paul Sabatier University, Toulouse's Teaching Hospital (CHU Toulouse), 31062 Toulouse, France.

Synovial chondromatosis is a non-cancerous tumor characterized by the formation of multiple nodules of cartilage due to metaplastic development of the synovial membrane. Etiology can be a primary lesion, of which pathogenesis remains unknown, or low-grade trauma or internal disorders. This pathology can long remain undiagnosed and leads to therapeutic wandering, especially since clinical manifestations are non-specific. Read More

Bone and Joint Reconstruction Research Center, Shafa Orthopedic Hospital, Iran University of Medical Sciences, Tehran, Iran.

The diagnosis of synovial chondromatosis (SCM) is usually delayed, as the arthroscopic-guided synovial biopsy is postponed owing to its invasive nature. We report the timely diagnosis of a giant solitary synovial chondromatosis of the hip in a 32-year-old woman using ultrasound-guided synovial biopsy. This technique revealed to be safe and successful in the diagnosis of SCM, when the imaging studies were obscure. Read More

Arthroscopic Management of Synovial Osteochondromatosis of the Elbow.

Arthrosc Tech 2021 Apr 13;10(4):e1103-e1108. Epub 2021 Mar 13.

Department of Orthopaedics and Traumatology, Hong Kong SAR, China.

Primary synovial chondromatosis is characterized by newly formed chondral or osteochondral nodules in the synovial membrane, which may detach and form loose bodies. The loose bodies can be calcified or ossified, and the condition is termed synovial osteochondromatosis. Three distinct stages can be identified in primary synovial chondromatosis : phase I is active synovitis without loose bodies, phase II shows nodular synovitis along with loose bodies, and phase III is characterized by the presence of loose bodies with the resolution of synovitis.
