Joint Ankylosis

A rapidly increasing number of mandibular condylar fractures and some complications related to injuries of temporomandibular elements make this study important. Intra-articular disorders lead to secondary pathological findings such as osteoarthritis, deforming osteoarthrosis, and temporomandibular joint ankylosis that limits mouth opening, mastication, swallowing, breathing, and decreased/lost working capacity or disability. Early diagnosis of intra-articular disorders can prevent from long-lasting functional complications caused by temporomandibular joint injuries. This study was performed for the purpose of early detection and investigation of organic pathological changes in the cartilaginous and osseous tissues of the temporomandibular joint caused by traumatic fractures of the mandibular condyle. Twenty patients underwent a general clinical examination, magnetic resonance imaging (MRI), and immune-enzyme testing for biochemical markers of connective tissue injury (pyridinoline and deoxypyridinoline) in urine. Disk dislocation, deformation, adhesion, perforation or squeeze, tension or disruption of ligaments, and injury of articular surfaces are among complications of mandibular fractures that can be revealed on MRI. As regards biochemical findings, we revealed a sharp rise in the levels of pyridinoline and deoxypyridinoline before treatment and a lack of stabilization within 21 days of treatment.
