Aim: The study describes the arthoscopic use of resorbable pins for the internal derangement of the temporomandibular joint with McCain's technique. Clinical and image features are reported retrospectively.
Methods: Twenty-seven consecutive patients (34 joints) were included. Symptomatic internal derangement and anterior-medial disc displacement with or without reduction in magnetic resonance images (MRI) were diagnosed in all cases. Two resorbable pins (SmartNail) were placed in each joint employing arthroscopic surgery with a third portal for disc recapture and fixation to condylar head.
Clinical data 24 months after surgery are reported (movements, pain score, clicking, laterodeviation, occlusal changes). In eight joints a MRI control was required between 1 and 2 years after surgery. Results: Visual analogue scale values (0-100) decreased from 70.8 to 11.9 (p < 0.001) in the first control (week) and kept down after 24 months of follow-up (VAS: 4.8). Movements began to recover in 3 months and mouth opening increased from 34 mm to 43.2 mm 1 year after surgery (p < 0.001). Clicking, laterodeviation and contralateral excursions improvement were statistically significant (p < 0.001). MRI showed disc fixation to condyle head in closed and opened mouth.
Conclusion: Disc fixation to condylar head with resorbable pins is a safe and satisfactory procedure. Pain becomes drastically reduced a
