Double Medial Elbow Bump: A Case Report of an Untreated Medial Epicondyle Fracture With Anterior Incarceration of the Fragment.

Medial epicondyle fractures are uncommon elbow injuries and require careful radiological evaluation for appropriate diagnosis and management. Missed or neglected medial epicondyle fractures, however, are reported as uncommon reports or small series. Incarceration of the medial epicondyle fragment within the elbow joint is often reported and poses therapeutic challenges. Severe displacement of the medial epicondyle fragment and its anterior incarceration within the soft tissues is a rare entity. Here, we report a two-month-old untreated case of an anteriorly displaced medial epicondyle fracture with anterior incarceration, presenting as a clinical bump adjacent to the native medial humeral condyle. This presentation of a double medial bump is uncommon and reported here for its rarity. The injury was finally managed with open reduction internal fixation of the displaced medial epicondyle fragment back to its native site along with the anterior transposition of the ulnar nerve. Good clinical outcome with full elbow range of motion and radiological union was achieved in the follow-up of 13 months.
