Brachial Artery Transection After a Closed Traumatic Isolated Medial Epicondyle Fracture in a Pediatric Patient: A Case Report.

Background: Medial epicondyle fractures in pediatric patients might be associated with an occult elbow dislocation and neurovascular damage.

Methods: A single case of a medial epicondyle fracture presenting with brachial artery transection was reviewed. Presentation, clinical course, and early outcome are reported.

Results: A 14-year-old patient presenting with an apparently isolated medial epicondyle fracture was found to have examination and diagnostic test findings consistent with brachial artery transection. His injury was explored and repaired acutely, resulting in acute return of perfusion. Final follow-up revealed 0° to 130° of flexion-extension arc of motion and full pronation and supination with normal sensory and motor function of the hand.

Conclusions: Pediatric medial epicondyle fractures should alert the clinician to the possibility of an occult dislocation of the elbow, and a full neurovascular assessment should be performed. Early recognition and repair of a vascular injury associated with this fracture can lead to a good outcome.
