A Rare Cause of Lateral Antebrachial Cutaneous Neuropathy Secondary to Internal Fixation of a Supracondylar Humeral Fracture: A Case Report

Case: We discuss a patient with a 6-month history of episodic elbow and forearm pain 6 years after supracondylar humeral fracture fixed with Steinmann pins at the age of 10 years and 5-year follow-up data at the age of 21 years. Electrodiagnostic studies exhibited no response from the lateral antebrachial cutaneous (LABC) nerve, and anesthetic injection demonstrated relief. Surgical intervention provided immediate relief of symptoms without recurrence for 5 years postsurgery. Conclusion: Atypical LABC neuromas can be found after operative fixation of supracondylar humerus fractures. Neuroma excision and intramuscular burying of affected nerve ends remains a viable treatment option for patients with late-presenting traumatic neuromas.
