Disc reposition with resorbable pins in TMJ arthroscopy. Clinical and MR findings at 12 months

Introduction: Procedures used in arthroscopic disc reposition, like suturing technique, are technically complex and they have questionable results. Clinical and MR imaging (pre and postoperative) findings in resorbable pins technique in a series of patients.

Methods: A prospective study was conducted in 26 patients (52 joints) that underwent arthroscopic surgery. Resorbable pin suturing technique was performed in 31 out of the 52 joints (Smart-Nail). Bilateral pins placed in 19% of cases and unilateral pin in 81%. All patients underwent MR before and one year after surgery. Clinical data were collected at the initial visit and 1, 3, 6 and 12 months after surgery and evaluated by a paired t -test, statistically significant at p < 0.05.

Results: Average follow-up period was 15 months. Patients reported decreased pain, with values of VAS under 20 and showing no pain or mild pain in 18/26 patients and MMO significantly increased, from 31 to 39 mm at one year ( p < 0.05). No significant changes in bone around pin. Malocclusion in 8/26 patients, disappeared in a month, except one case required its removal.

Conclusions: The use of resorbable pins seems to be a useful and effective technique for fixation of the articular disc. Further long-term studies should be done.
