Background Posterolateral rotatory instability of elbow is considered to be due the disruption ulnar part lateral collateral ligament (LUCL). This pattern may also induced by a fracture components column. Results We present case 16-year-old boy who fell on his left outstretched arm as he attempted jump over tennis net. On initial physical examination, had found varus stress and radial head could felt posteriorly. With valgus supination force combined with axial loading, gapped open patient sense increased instability. X-rays showed humeral epicondyle posterolateral subluxation elbow. In operating room, was have reproducible The fractured off humerus LUCL still attached fragment. reduced, injury stabilized small screws suture anchors. At 6-month follow-up, pain-free, examination revealed 170° flexion, full extension, 90° pronation, 65° supination. healing concentric reduction joint. Conclusion fractures, affected should assessed for any signs associated If clear are seen that would prohibit proper postinjury rehabilitation, then surgical fixation reinforcement an effective method treatment.
