Synovial chondromatosis associated with experimental osteoarthritis in adult monkeys

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

“…The etiology of the disease has not been completely clarified, but may involve secondary reactive metaplasia after trauma or chronic abnormal loading leading to detachment of chondrocytes. The role of microtrauma in the development of secondary SC has been suggested and demonstrated in an animal model by HELMY et al 4 , it was shown that SC was part of a process of osteoarthritis, secondary to trauma, which caused the loss of the shock absorption function of the intact TMJ disc. McCAIN et al 8 suggested that a traumatic episode could dislodge cartilaginous and/or bony tissue into the joint space, where it may be captured in the synovial tissue.…”

Helms et al (Helmy et al, 1989), demostraron el rol del micro trauma en modelos animal, postulando la CS como parte de un proceso de osteoartritis. (González-Pérez et al, 2011).…”

“…Travmaya sekonder olarak geliştiğini ve İntakt TME' şok absorbiyon fonksiyonunu engellediği için osteoartrit gelişimine neden olduğunu rapor etmişlerdir. 27 Klinik olarak en yaygın osteoartrit semptomları ise şişlik, palpasyonda hassasiyet, krepitasyon, kısıtlı ağız açıklığıdır. Ağrı genellikle gündüzleri orta düzeydeyken, aktivite sonrasında artış gösterir.…”
