Short-Term Outcomes of Herbert Screw Fixation for Isolated Olecranon Fractures in Children: A Single-Institution Retrospective Study.

Abstract

The aim of this study was to assess the clinical and radiological outcomes of closed reduction with percutaneous Herbert screw fixation in children with isolated olecranon fractures. We retrospectively reviewed the records of children treated at our center for isolated olecranon fractures (Mayo type IIA) with closed reduction and percutaneous Herbert screw fixation. The related indices and data of the group were collected for comparative analysis after an average follow-up of 6-8 months. The Herbert screws were removed by a second operation. Overall, 14 patients with an average age at the time of injury of 11.36 (range 10-14) years were included. All patients had good radiological and clinical outcomes at 6-8 months postoperatively; all had normal elbow ranges of motion and showed complete bone healing on radiographs. There were no foreign body irritation, implant migration, or osteoarthritis cases. Premature epiphyseal closure was noted in six patients. The average QuickDASH score was 1.58. Fixation of olecranon fractures with Herbert screws is a safe and easy method in young patients, leading to good functional and radiological results. Nonetheless, determination of the effects of this treatment method on the olecranon ossification center requires long-term follow-up.
