Effect of a functional brace in combination with physical therapy for early correction of cubitus varus in young children

Abstract

Abstract Background This study aimed to assess the clinical and radiologic outcomes of a functional brace in combination with physical therapy (FBPT) for early correction of cubitus varus in young children. Methods Eighteen consecutive patients with cubitus varus secondary to supracondylar fractures were enrolled between July 2017 and March 2019. We used the FBPT technique to correct varus and sagittal plane deformity for early cubitus varus in young children. The clinical evaluation included measurement of varus angulation, sagittal plane, and range of motion at three, six, and twelve months post-intervention. The clinical and radiographic results were assessed according to the Bellemore criteria. Results Pre-treatment humerus-elbow-wrist (HEW) angle measured on the affected side (varus deformity) ranged between -38° and -12° (average, -23.2°) while the post-treatment HEW angle ranged between -10° and + 15° (average, 8.8°). Compared with the unaffected side, no statistically significant difference was found in the affected side post-intervention (P > 0.05). According to the Bellemore criteria, we got excellent results in fourteen patients (77.8%), good results in three patients (16.7%), and poor result in one patient (5.5%). All patients and their parents (except one patient with residual varus deformities) were satisfied with the functional and cosmetic outcomes. Conclusions The FBPT is effective for the treatment of cubitus varus in children, especially for young children within 6 months of the injury.
