Synovial chondromatosis of the temporomandibular joint possibly secondary to trauma

Three Case Reports of Synovial Chondromatosis of Temporomandibular Joint: Histopathologic Analyses of Minute Cartilaginous Loose Bodies From Joint Lavage Fluid and Comparison With Phase II and III Cases

“…12 The reports of SC cases that occur after trauma suggest an etiologic correlation between SC and trauma. [5][6][7][8] McCain and de la Rua 6 hypothesized that a traumatic experience could separate cartilaginous tissue into the joint space, where it might be captured in the synovial tissue. Subsequently, these fragments, receiving nutrients from the synovium layer, could overgrow and undergo calcification.…”

“…Cases of SC arising secondary to trauma [5][6][7][8] have been reported, of which some were found to be in phase III. 6,7 In addition, TMDs with clenching, clicking, or trismus are conditions that indicate the patient has chronic traumatic irritation.…”

“…6,7 In addition, TMDs with clenching, clicking, or trismus are conditions that indicate the patient has chronic traumatic irritation. Therefore, it appears that the etiology of cartilaginous loose body formation can be attributed to other pathways.…”

Potential utility of anti‐TNF drugs in synovial chondromatosis associated with ankylosing spondylitis

“…The exact prevalence of primary or secondary SC is unknown, but a few representative case series showed 38 SC cases of all inhabitants (127 000) population in Spain and 20 cases were primary SC, 136 cases of loose bodies in joints over 7 years at Hospital for Special Surgery in New York and 10 cases were primary SC, 4 cases of 107 synovial biopsies over 12 years in Hong Kong,78 of 30 000 orthopedic patients over 32 years at Birmingham Hospital in the UK . Associated SC conditions such as trauma (72 cases) degenerative joint diseases (44 cases) metabolic joint diseases (4 cases) immune inflammatory (9 reported casesand present case) and other diseases (15 cases) were previously reported. AS, ankylosing spondylitis; FOP, fibrodysplasia ossificans progressive; LS, lumbar spondylolisthesis; OC, osteochondrom; OP, osteopoikilosis; PVNS, pigmented villonodular synovitis; RP, relapsing polychondritis…”

A case of synovial chondromatosis of the temporomandibular joint secondary to preauricular trauma

“…Temporomandibular joint (TMJ) involvement with SC is relatively uncommon. To the authors' knowledge, most descriptions of SC in the TMJ are isolated cases and small series [1][2][3][5][6][7]9,10 . The etiology has not been completely clarified.…”
