APPLIANCE OF SPINE POSTERIOR SUPPORT COMPLEX X-RAY ANATOMIC PARAMETERS IN PLANNING SURGICAL ACCESS

Objеctivе. Analysis of the x-ray anatomic parameters of the posterior support complex of the spine at the lum bosacral level and evaluation of their use possi bility in planning a surgical access to the affected segment.

Matеrials and mеthods. The study group included 67 patients operated on for the degenerative-dystrophic pathology of the lum bosacral spine. The x-ray anatomical parameters of the spinous processes, arches of verte brae, interspinosus and interlaminar spaces were studied in three lum bar segments using the Onis program. Kruskel - Wallis test (K - W test) was used to determine the statistically significant differences  between the studied segments. The differences were considered statistically significant at P<0.05.

Rеsults. The study revealed significant differences  between three analyzed segments in the parameters of the arches (P<0.0001), interspinosus (P<0.001), and interlaminar (P<0.001) spaces. A technique for using the studied parameters for planning a surgical access using the graphic visualization data and the intraoperative support means was developed and tested.

Conclusion. The proposed technique of determining the technical aspects of a surgical access is  based on the analysis of the x-ray anatomy of the posterior support complex and is aimed at increasing the accuracy and safety of surgical manipulations performed during accessing the targeted segment. The developed means of the intraoperative support ensure the calculation data implementation making possi ble the technique use as an alternative means to the modern x- ray identification tools.
