Irreducible Complex Posterior Elbow Dislocation with Varus Posteromedial Rotary Instability – A Case Report

Published Date: 24th June 2024

Publication Authors: Rana. A

Introduction
Elbow dislocations, particularly those associated with varus posteromedial rotary instability, are relatively uncommon. We present the case of a 25-year-old male initially managed nonoperatively for a posterior elbow dislocation, who subsequently experienced irreducible re-dislocation with characteristic fractures of the anteromedial facet and tip of the coronoid, indicative of varus posteromedial rotary instability.

Case Report
Following an unsuccessful attempt at closed reduction under general anesthesia, open reduction was performed, revealing the interposition of the posterior capsule of the humero-ulnar joint as the cause of irreducibility. Fixation of the coronoid fracture was undertaken, and the patient exhibited excellent functional outcomes at a 4.5-year follow-up.

Conclusion
This case underscores the rarity of irreducible elbow dislocation in the context of varus posteromedial rotary instability and highlights the crucial role of capsular interposition in such cases. Successful open reduction, coronoid fixation, and attentive postoperative care contributed to the patient’s favorable long-term functional outcome.
