A unique case of asymmetric bilateral shoulder dislocation with proximal humeral fractures: Case report

Background

Unilateral anterior shoulder dislocation is the most common joint dislocation, accounting for 95% of cases, while posterior dislocations are rare, comprising 2–5%. Bilateral shoulder dislocations are uncommon, with posterior types more frequent than anterior or inferior ones. Asymmetrical bilateral fracture dislocations, featuring one anterior and one posterior dislocation, are exceedingly rare.

Case Description

We report a unique case of a 25-year-old male fitness coach who presented with asymmetrical bilateral shoulder dislocations following a fall after a convulsive episode. The right shoulder was anteriorly dislocated, and the left was posteriorly dislocated, both with proximal humeral fractures.

Conclusion

Asymmetrical bilateral shoulder dislocations with proximal humeral fractures are extremely rare. Accurate history-taking, thorough clinical examination, and appropriate imaging are crucial for timely diagnosis and effective management to avoid complications.
