title: [Acromio-clavicular dislocations treated by synthetic coraco-clavicular ligamentoplasty].
abstract: OBJECTIVE
  The aim of this study was to evaluate results of coraco-clavicular ligamentoplasty using a synthetic material, dacrylene, for the treatment of recent and neglected acromio-clavicular dislocation.
  
  
  METHODS
  The series initially included 104 patients who underwent surgery from 1981 to 2001. Among these, 75 were reviewed with a mean follow-up of 85 months (72% review rate). A complete set of clinical (Constant score/100 points) and radiographic (coraco-clavicular distance) data was available for 39 patients. Thirty-six answered a questionnaire with measurement of a partial Constant score (65 points).
  
  
  RESULTS
  Seventy-seven percent of patients were satisfied or very satisfied and 98% presented good or very good functional outcome as assessed by the partial Constant score. Reduction of the coraco-clavicular distance was satisfactory for 54% of patients evaluated. For the vast majority, insufficient reduction was reducible and had no impact on the functional outcome. The time to treatment (recent or neglected dislocation) had no effect on patient satisfaction or functional outcome. The coraco-clavicular distance was greater for dislocations operated on late (p<0.05). The grade of the injury, the type of assembly used, and use or not of lateral clavicular resection had no effect on clinical or radiological outcomes. Dacrylene was tolerated poorly by 14 patients (18.7%). The functional outcome was very good for all after removal of the ligament.
  
  
  CONCLUSIONS
  Functional results are good with this technique which enables a well sustained stable reduction of recent and neglected dislocations, irrespective of the grade of the lesion or the type of assembly used. Reducing the mechanical stress on the ligament and prudent rehabilitation exercises should be helpful in preventing intolerance reactions.
