title: Evaluation of postoperative results from videoarthroscopic treatment for recurrent shoulder dislocation using metal anchors.
abstract: OBJECTIVE
  To clinically and radiologically evaluate the results from videoarthroscopic treatment using metal anchors in patients with recurrent shoulder dislocation and its complications.
  
  
  METHODS
  This was a retrospective study on 47 patients (47 shoulders) operated by the shoulder group of the orthopedic hospital between February 2010 and February 2012. A questionnaire, interview and physical and radiographic examinations were used, with the classification of Samilson and Pietro. The mean postoperative follow-up was 33 months (range 12-47 months). The statistical analysis consisted of using Fisher's exact test through the IBM SPSS 22 statistical software. The significance level used was 5%.
  
  
  RESULTS
  Recurrence was observed in nine cases. The patients were, on average, 26.5 years old at the first episode, and 19.1% were aged 20 years or under. Among these, 55.6% presented recurrence. In relation to age at the time of the surgical procedure, the average age was 27 years, and 12.8% were aged 20 years or under. Nineteen patients presented prominent anchors and, of these, 21% manifested arthrosis.
  
  
  CONCLUSIONS
  There was a statistically identified correlation between the recurrence rate and age less than or equal to 20 years at the times of first dislocation and the surgical procedure. Further studies should be conducted in order to compare the use of absorbable anchors, which despite higher cost, may provide lower risk of developing glenohumeral arthrosis in some cases.
