Despite being very common, lateral condyle fractures in children are rarely associated with acute nerve injuries. We present the case of a 10-year-old, left-handed male child who presented with a left lateral humeral condyle fracture associated with radial nerve injury. The patient was managed by open reduction and internal fixation plus radial nerve exploration, which was found entrapped in the fracture site. The patient achieved full recovery after 16 weeks. We report this case to present the approach and the operative findings and to emphasize the importance of a preoperative clinical examination in addition to preoperative planning to achieve a favorable outcome.
