Simultaneous acromioclavicular dislocation, proximal humeral fracture, and reverse Hill-Sachs lesion: a case report.

BACKGROUND

In cases with injuries to the shoulder region, the combination of acromioclavicular joint dislocation, reverse Hill-Sachs lesion, and proximal humeral fracture is a very rare condition.

CASE PRESENTATION

This study described a 38-year-old male Persian patient with simultaneous acromioclavicular joint dislocation, proximal humeral fracture, and reverse Hill-Sachs lesion due to motor vehicle crash injury who underwent arthroscopic acromioclavicular joint fixation using tight rope technique. In the 7-month follow-up period following the surgical fixation, range of motion was approximately normal. Reduction and hardware were intact, no dislocation or apprehension to dislocation was observed. Patient only had minor shoulder pain at the end of range of motion and a dull pain on the site of incision over the clavicle in deep touch. Our findings showed acceptable arthroscopic outcomes in the management of such complex case.

CONCLUSION

Our experience on this case showed acceptable outcomes of the arthroscopic treatment of the acromioclavicular joint dislocation in the management of such a complex case with associated injuries to the shoulder region.
