Guided Growth With Minifragment Plates for Angular Deformities in the Distal Radius in Skeletally Immature Patients. Preliminary Results.

ABSTRACT

INTRODUCTION: Growth modulation allows correction of progressive ulnar deviation of the distal radius in skeletally immature patients, which may occur as a consequence of various pathologies. The aim of this study is to evaluate the radiographic results and complication rate in a series of patients treated with minifragment plates. METHODS: The medical records of 12 patients who underwent guided growth with a minifragment plate on the radial aspect of the distal radius as a consequence of angular deformities in the distal radius were retrospectively reviewed. Demographic data, radiographic changes, and complication rate were analyzed. RESULTS: A total of 14 wrists and forearms were evaluated. The mean age at which surgery was performed was 10.5 years (interquartile range 9.0 to 11.3). The average time between placement and removal of the material was 28.7 months (SD 8,89). In each case, a general improvement of the radiographic parameters was obtained. There were 3 postoperative complications, but only 1 of them required reintervention (broken metaphyseal screw). CONCLUSIONS: Hemiepiphysiodesis using a minifragment plate is a treatment that respects the surgical anatomy and offers an alternative surgical option for angular deformities of the distal radius in children.
