An Unreported Variant of Convergent Dislocation of Elbow.

INTRODUCTION

Pediatric traumatic elbow dislocation is an uncommon injury accounting for 3-% of all pediatric elbow injuries. It can present as an isolated injury or in association with fractures of radius, ulna, or humerus. Posterolateral type is the most common accounting for 70% of all pediatric elbow dislocations. Other less common types are anterior, medial, lateral, convergent, and divergent dislocations. We describe an unreported variant of convergent elbow dislocation.

CASE REPORT: This is the case report of a convergent elbow dislocation with a radial neck fracture and proximal ulna fracture with ulnar nerve paresthesia in an 11-year-old boy. To the best of our knowledge, this is the first case report with these concomitant injuries.

CONCLUSION

The current case shows stepwise approach to this variety of injury where anatomical reduction of both ulnar and radial fractures was required to achieve a good range of motion at the elbow and forearm at the long term.
