STRUCTURAL VARIANTS OF THE LUMBAR FACET JOINTS
207 KB
This work presents the results of the study of morphometric characteristics of anatomical structures of spinal motion segments of normal lumbar spine. In this study of spinal motion segments have been identified structural variants of congruent articular facet surfaces. We have found that there are two types of facet joints structure - I type with the presence of flat articular surfaces and type II, with the presence of a convex articular surface of the lower articular process of the overlying vertebra and a concave upper articular surfaces underlying vertebra. In accordance with the presence of pairing facet joints we have determined the presence of four different structural variants of facet joints: 1st variant - the presence of the two joints with flat articular surfaces; 2nd variant with the presence of right and left joint with a convex articular surface of the lower articular processes of the overlying vertebra and concave upper articular surface underlying vertebra; The 3rd variant and 4th variant - with the presence of bilateral asymmetry of the articular surface. Evaluated the frequency of identified structural facet joints variants of the according to sex of the patients.
