Percutaneous k-wire leverage reduction and retrograde transphyseal k-wire fixation of angulated radial neck fractures in children.

Abstract

To describe clinical and radiographic outcomes after surgical management of angulated radial neck fracture in children. Twenty children (aged 2-11 years) with angulated radial neck fracture with more than 30° angulations (Judet type III and IV fractures) were retrospectively reviewed. All the enrolled patients were surgically treated with percutaneous k-wire leverage reduction and retrograde transphyseal k-wire fixation. Clinical outcomes were evaluated using Tibone and Stoltz score and the Mayo Elbow Performance Score (MEPS). Radiographic outcomes were evaluated with Métaizeau score. Complications were also evaluated. At a mean follow-up of 20 months, no patients showed axial deformity of the upper limb or instability of the elbow. The mean value of the MEPS was 99.2, and excellent clinical results were achieved in 14 patients (73.7%) at Tibone and Stoltz score. The final X-rays showed fracture healing in all patients; furthermore, 75% of patients showed excellent reduction at Métaizeau score. No patient developed complication. There were no iatrogenic nerve injuries or pin infections. The results demonstrate that percutaneous k-wire leverage reduction and retrograde transphyseal k-wire fixation of angulated radial neck fracture treatment is a simple, effective, rapid and inexpensive procedure.
