Introduction:
Posterior shoulder dislocations comprise a small percentage of shoulder dislocations. Even more uncommon are posterior shoulder fracture-dislocations, which are commonly associated with trauma, seizures, and electrical shock.
Presentation of case:
We present the case of a 64-year-old right-hand dominant male who sustained bilateral shoulder posterior fracture-dislocations after a hypoglycemia-induced seizure. The patient was treated with bilateral reverse total shoulder arthroplasties in a single-stage. He recovered well and continues to have excellent function and range of motion at 4-year follow-up.
Discussion:
Treatment options for proximal humerus fracture-dislocations include open reduction internal fixation (ORIF), hemiarthroplasty, and reverse total shoulder arthroplasty (RTSA). The indications for reverse total shoulder arthroplasty continue to expand.
Conclusion:
This is a rare case of bilateral posterior shoulder fracture-dislocations. In similar cases, simultaneous reverse total shoulder arthroplasties can be considered as a viable treatment option.
