The use of the Ortho-SUV navigation system in the treatment of children with forearm deformities

Abstract

Relevance. According to various authors, in children against the background of a number of congenital dysplastic diseases of the skeleton, various multilane deformities of the forearm bones are formed during growth. The most common deformities of the forearm in children occur against the background of hereditary multiple exostoses. Currently, the main method of surgical treatment of children with this pathology is the method of transosseous osteosynthesis using external fixation devices. In some cases, in order to eliminate pronounced angular deformations of the forearm bones, it is advisable to use a passive computer navigation system, which creates the need for a comparative analysis of the results achieved. The aim is to conduct a comparative analysis of the results of correction of multilane deformities of the forearm bones in children using the Ortho—SUV repositional node based on passive computer navigation. Materials and materials. The results of examination and treatment of 36 patients aged 4 to 16 years with forearm deformities on the background of exostosis chondrodysplasia were analyzed. All patients were examined and treated in the period from 2008 to 2022. The patients were divided into 2 groups: the main group and the control group. The main group included 13 patients who underwent correction of angular deformities of the forearm bones using an Ortho-SUV repositional node based on passive computer navigation. The control group (comparison group) included 23 patients who underwent deformation correction without the use of a repositional Ortho-SUV node. Results. A comparative assessment of the results showed that in the main group of the study, in the long-term follow-up period, a significant increase in the amplitude of rotational movements of the forearm was mostly in patients of the main group (in 69.2% of cases, n=9), on average by 10°. Conclusion. The use of a universal repositional Ortho-SUV node for the correction of multi-plane deformities of the forearm bones in children allows for the dosed elimination of all available components of curvature with high accuracy, thereby achieving "good" radiological and functional results in 92.3% of observations.
