dc.description.abstractObjective: The aim of this study was to clarify the role of different mechanisms in nerve injury during arm abduction positions. The tasks were to determine the strain deformation of the plexus brachialis during arm abduction, to measure the pressures in the neurovascular bundle in the cervico-costoclavicular-axillary area, and evaluate the histological changes of nerve after the stretch test. Material and Methods: During the cadaveric study on 7 specimens 7-20 h after death, strain deformation of plexus brachialis as well as compression deformation caused by the surrounding structures of the neurovascular bundle were investigated in the arm abduction position of 0°, 90°, 12°, 150°, and 180°. One nerve sample was studied histologically after 15% stretch on the bench. Results: The relative strain deformation of 3%-23% was documented during 0° to 180° abduction tests. The strain deformation from 0° to 90° was significant (P<0.001). The mean pressure change in the bundle was 13.6 mm Hg at 90°, 53.7 mm Hg at 120°, 73.4 mm Hg at 150°, and 89.0 mm Hg at 180° arm abduction. An increase in pressure was significant in the intervals: 0°-90° (P<0.001), 91°-120° (P<0.001), 121°-150° (P<0.001) and 151°-180° (P<0.05). Conclusions: Nerve traction and tissue compression arising during the arm abduction above 90° were found to be sufficient to induce lesions in neural bundles of the plexus brachialis.en
