Abstract :

Background: Symptomatic chronic acromio–clavicular joint dislocation cause significant morbidity affecting daily activities. Presence of various treatment options makes management controversial. This prospective study was conducted to assess the outcome of Modified Weaver Dunn procedure. Materials & methods: Forty–three consecutive patients suffering from significant pain and disability from chronic acromio–clavicular dislocation (Rockwood types III–V) were included in the study. They underwent Modified Weaver Dunn procedure and were followed up for two years. Results: Mean ASES score improved from 66±7 points preoperatively to 82±5 postoperatively. Mean Constant score improved from 66±4 to 80±6. Both were statistically significant (p<0.001). The patients could resume their work after an average of 18.3 weeks. Radiologically, the mean coraco–clavicular distance improved significantly (p<0.001) from 19±7.5mm pre–operatively to 11.4±2.8mm post–operatively. Conclusion: By virtue of being based on sound biomechanical principles and relative ease of execution, Modified Weaver–Dunn surgery may be the preferred procedure in chronic symptomatic acromio–clavicular dislocations.
