Turchin O. Operative correction of foot deformities of the patients with hereditary motor-sensory neuropathy

The analysis of complex clinical and roentgenological, biomechanics, electromiographyc investigations were presented in the thesis including treatment of 89 patients (172 feet) with cavus foot of hereditary motor-sensory neuropathy. The structure of the anterior equines in 13 patients (24 feet) has been studied. The leading role of the pair antagonists - long flexors and extensors of the first and II-V toes in mechanogenesis of the anterior equines has been shown. Research of biomechanics showed that after surgical correction have been improved the power characteristics of long flexors and extensors of the foot, which were caused by increasing of arm lever of m. triceps surae, which was coincided with increasing the power characteristics in 1,2. Walking patients with GMSN manifested a significant distortion of the PR curves, slowing down and increasing energy efficiency, a significant lateral instability, which is observed in the transverse component of the PR, the changes which are manifested its deformation, the appearance of additional teeth, displacement of contours, an increase in pulse magnitude and time of single support the load. Developed and clinically tested diagnostic-therapeutic algorithm that takes into account the radiological hollow structure deformation, character electroneuromiographic and biomechanical changes. Results of surgical treatment, evaluated for the AOFAS, was 80, 3%, which proves the high efficiency of the algorithm.
