The effectiveness of endoscopic brachial plexus neurolysis in the treatment of brachial plexus palsy in adults

Introduction The method of endoscopic revision, neurolysis and decompression of the brachial plexus is a current minimally invasive method of treatment. It is able to completely preserve the anatomical structures (skin, fascia, muscles, clavicle, arteries, veins, nerves) and minimize damage to the structures of the brachial plexus, since neurolysis is carried out along the trunks and bundles of the plexus through a low-invasive transaxillary approach. However, the effectiveness of this type of operation has not been studied previously. The aim of the study To evaluate the effectiveness of brachial plexus neurolysis under video endoscopic assistance in the treatment of brachioplexopathies in adults Materials and methods The study involved patients hospitalized in the Tyumen Federal Center for the period from 2017 to 2022 with a diagnosis of brachial plexus palsy, who, for medical reasons, underwent neurolysis of the brachial plexus under video endoscopic assistance. The number of patients gave informed concent was 25 subjects. The results of treatment were assessed with score systems and questionnaires; neurological examination was performed and muscle strength was assessed according to the British scale (M5-M0), the type of sensory disorders and their degree on a scale from 0 to 10, where 10 is the complete preservation of sensitivity, and 0 is its complete absence and were confirmed by the data of functional diagnostics (stimulation ENMG) 3, 6 and 12 months after the operation. Statistical data processing was carried out using the Microsoft Excel (Microsoft Office 365) and Stattech 2.0 software package. For quantitative traits, the arithmetic mean (M) and standard error of the mean (SEM) were calculated. To assess the statistical significance of the results obtained, the parametric t-Student's test was used.
