VARIANTS OF THE STRUCTURE OF SOME BONE STRUCTURES OF THE OCCIPITOATLANTOAXIAL COMPLEX

Morphoscopic and morphometric studies of bone structures of the occipitoatlantoaxial complex were performed. The shapes and sizes of the large occipital opening, the vertebral opening of the Atlas, and the articular surfaces included in the studied complex are determined. The work was performed on the materials of the craniological and osteological collections of the Department of normal anatomy of the Military medical Academy. S. M. Kirov. Based on the visualization method, identical forms of articular surfaces on the condyles and pits of the Atlanta lateral masses were identified: oval, with rounded anterior and posterior poles, diamond-shaped and sinuous, and also in the form of an asymmetric eight with fragmentation phenomena. A program of measurements was made based on morphoscopy materials. The maximum longitudinal and transverse dimensions of all six joints of the complex (right and left) were determined. The measurement data were processed using the variational statistics method.
