Symptomatic Nonunion of the Medial Humeral Epicondyle Fracture: A Case Report and Review of the Literature

Symptomatic nonunion of medial epicondyle fractures of the humerus is a rare entity. The surgical technique can be difficult due to anatomic and biomechanical factors, such as the high tension and the torsional forces applied from the flexor-pronator tendon origin. The most common complications of nonunion of the medial humeral epicondyle fracture are chronic pain, instability in valgus of the elbow, and neuropathy of the ulnar nerve. We described the case of 1 patient with symptomatic medial humeral epicondyle nonunion, who underwent open reduction and internal fixation with excellent clinical evolution after 1 year of follow-up from time of surgery. The purpose of this study was to evaluate the outcome of open reduction and internal fixation of a medial epicondyle nonunion fragment in 1 case and present a review of the literature.
