SOME OPTIONS OF FETAL TOPOGRAPHY OF THE LONG BRANCHES OF THE CROSS PLEXUS

Abstract

In the conditions of wartime, the frequency of damage to the nerves of the lower extremity increased sharply. Open injuries make up the vast majority of peripheral nerve injuries. Understanding variations in the topography and the condition of the surrounding soft tissue structures allows for a detailed assessment of the condition of the peripheral nerves of the lower limb, to diagnose the exact site of damage, the type of neuropathy, and to choose treatment and rehabilitation tactics. The purpose of the study will be to establish variants of the fetal topography of the long branches of the sacral plexus. The material for the study of topographical and anatomical features of the long branches of the sacral plexus was 26 human fetuses of 5-7 months. The sciatic nerve is the largest nerve in humans, originating from the ventral division of spinal nerves L4 to S3 and containing fi bers from both the posterior and anterior lumbosacral plexuses. The sciatic nerve runs along the entire back surface of the lower limb up to the foot. The sciatic nerve innervates a signifi cant part of the skin and muscles of the thigh, lower leg, and foot. It was established that the long branches of the sacral plexus can be subjected to compression or damage in diff erent parts of its anatomical course. Among the variants of the anatomical variability of the long branches of the sacral plexus, the topography of the sciatic nerve is the most common. In the three studied fetuses of 180.0 mm, 215.0 mm, 255 mm TKD, a high branching variant of the sciatic nerve was detected, and the features of the long branches of the sacral plexus in the specifi ed fetuses were unilateral. In this case, when assessing clinical symptoms, practicing doctors should take into account options for bilateral asymmetry. Prospects for further research. Deepening the study of the variant anatomy of the long branches of the sacral plexus in human fetuses of diff erent ages.
