Midshaft ulnar stress reaction in the adolescent female athlete: a case series.

Abstract

Ulnar stress injuries can arise in athletes participating in repetitive, high-stress activities involving the upper extremities. The aim of this study was to highlight the importance of diagnosing midshaft ulnar stress reactions and underscore the importance of early recognition and intervention. We present three adolescent female athletes who developed midshaft ulnar stress reactions, diagnosed with advanced imaging modalities. Stress reactions of the ulna diaphysis are uncommon injuries, and our case series highlights the importance of having a high index of suspicion in high-risk patients. All three of our patients were adolescent female softball pitchers. It is important to review a patient's history, perform a careful physical exam, and provide an appropriate work-up in the diagnosis and treatment of midshaft ulnar stress reactions. Without timely diagnosis and treatment, ulnar injuries can lead to significant fractures requiring prolonged recovery.
