Background and Aims: Acromioclavicular joint dislocation correspond to 8.6% of all joint dislocations & represents a major
injury to shoulder girdle. Non operative treatment is considered standard care of Grade 1 &2 acromioclavicular joint dislocation
but the treatment of acute Grade 3 &above injuries is still controversial. The study aims to enumerate various modalities of
treatment of acromioclavicular joint dislocation & to assess functional outcome & radiographic outcome & range of movement at
acromioclavicular joint. Methods: It is a prospective observational study .The clinical and radiological examination of 12 cases
with acromioclavicular joint dislocation who came to emergency department in a period of two & half years was conducted.
Results: In our study 12 patients with acromioclavicular joint dislocation with mechanism of injury being Road traffic accident
[83.33%] & fall from height [16.67%] where injury is by direct force which is produced by patient falling onto point of shoulder
with arm at the side in adducted position .The condition is seen most prominently in age group between 20-30 years [66.67%].
Males are mostly affected [83%]. Involvement of left side was more than right side with a ratio 1.4:1. The condition was
classified based on Tossy -Rockwood classification. Among the 12 cases one case was classified as Type -1 [8.3%], two cases
were classified as Type-2[16.67%],four cases were classified as Type-3[33.33%],five cases were classified as belonging to Type-
5. Type-5 was the most common type. Among them 5 cases [type 1-one case; type 2-two cases; type 3-two cases] were treated
conservatively by jones strapping. Two cases belonging to type-3 and five cases belonging to type -5 were treated surgically
by modified weaver dunns procedure with autologous semitendinosus graft augmentation. Conclusion: Acromioclavicular
joint dislocation was caused due to high velocity injury to shoulder girdle affecting 20-30 years age group.Males were most
affected .Type 1 and Type 2 acromioclavicular joint dislocation can be managed conservatively yielding good results.Type 3
acromioclavicular joint dislocation yielded almost similar results by operative &non operative treatment. Type 5 when managed
surgically yielded execellent results.Incidence of type 4&type6 acromioclavicular joint dislocation was very low.
