The role of anatomical and topographic features of angioarchitectonics and nerve gliding for its recovery

Abstract

In the modern concept of treatment of patients with injuries of peripheral nerves, the main thing is to understand the mechanism of its sliding and the peculiarities of blood supply. Studying the nerve topographic anatomy, we are convinced that the mobility of the nerve exists not only in relation to the tissues surrounding it, but also at the level of its inner bundles. In this article, we report on the different degree of nerve mobility depending on its location zone, and that the ulnar and median nerves have the highest degree of mobility at the level of the forearm distal third. To calculate the change in the glide of the nerves, a mathematical model was constructed to measure their mobility during flexion and extension in the elbow joint, allowing to personalize the flap plasty depending on the length of the autograph vascular pedicle. The anatomical and topographic features of the angioarchitectonics of the nerve at various levels were studied, the presence and variability of the location of the vascular pedicle of blood-supplied autografts were studied. The obtained knowledge is necessary for carrying out revascularization of the damaged nerve zone with various types of autografts with autonomous blood flow. Conclusions. Knowledge of the anatomical and topographic features of peripheral nerves, their blood supply and mobility is necessary for their recovery for various injuries.
