Lateral condyle fractures are second most common fractures around elbow in children. There is no unanimity in the literature as to what constitutes ‘a late presentation’ or a neglected fracture. In authors opinion any displaced and rotated lateral condyle fracture untreated for 3 weeks should be labeled as neglected lateral condyle fracture. In case of an undisplaced or minimally displaced fracture, this duration can be extended for 6 weeks. Causes of neglect include treatment by osteopath, missed diagnosis, or late displacement of a minimally displaced fracture. A neglected lateral condyle fracture can present with progressively increasing valgus deformity because of non union, pain and apprehension in using the elbow because of instability or tardy ulnar nerve palsy. Many surgeons in the past have reported unsatisfactory results with delayed open reduction. Patients with non union are managed depending on the presenting disability of the patient. Those with cubitus valgus with good range of motion are managed with correction of deformity with no attempt at reunion. If the patient has an associated Tardy Ulnar Nerve Palsy, anterior transposition of ulnar nerve is also performed. Unless the patient has apprehension using the arm or pain on instability an attempt at osteosynthesis of ununited fragment is not made. If associated osteosynthesis is also attempted, then preferably a screw is used and bone graft added at the metaphyseal area. In case fixation of ununited fracture is attempted, complications include possibility of stiffness, avascular necrosis and fish tail deformity.
