The purpose was to reveal patterns of morphometric characteristics variability of lumbar vertebrae and sacrum for a choice of more adequate selection of standard sizes and introduction orientation of corrigent metalware at surgical treatment of spondylolisthesis. Preparations of lumbar vertebrae and sacrum of 60 skeletons, 110 Kt-grams of men and women of the first and second periods of mature age without visible pathology of a backbone and 300 Kt-grams of patients with spondylolisthesis. The data on age variability and sexual dimorphism of lumbar vertebrae and sacrum were obtained. The analysis of results of surgical treatment of 288 patients with spondylolisthesis during 1995-2008 was carried out. 160 patients were managed with preoperative planning, taking into account morphometric characteristics of vertebrae and sacrum since 2003. It is necessary to install and arrange metalware at reduction taking into account features of back structures and forward basic complex of lumbar vertebrae and sacrum; that allows to receive adequate decompression of neurovascu-lar structures in 85-90% cases, reliable correction and stabilization of damaged lumbosacral segments

CII arch fractures are divided into groups according not to anatomical localization, but to the instability degree resulted from the trauma. Effendi et al classification became greatly widespread. |t is based on the same stability criteria, but it is simpler, intelligible and gives the plan of treatment. All the fractures according to this classification are divided into three types: the first one consists in stable fractures in which even in functional images there is no any rough deformation at the level of CII segment; the second one consists in damages with significant angular (more than 11°) or shift (more than 3,5 mm) deformations, that indirectly indicates damage of soft tissue structures, and first of all diskoligamentous complex. The services of the authors of the present classification are also that they were the first who had defined fracture-dislocation of CII arch, attributed it to the third type. Choice of surgical procedure in unstable CII-III vertebral fractures is ventral spondylosyndesis of CII-III carried out by submaxillary approach after the preliminary closed elimination of deformation of upper cervical part of spine. The differentiated approach to the implant choice with an allowance for morphometric data allows to receive adequate decompression of nervous - vascular structures and reliable stabilization of the damaged segment

On the basis of biometric research of an aorta, glands internal secretion (testes, prostate and thyroid glands), leather and roentgenograms of brushes from 587 corpses of persons man`s and a female in the age of from 17 and more 75 years are calculated the equations of pair and plural linear regress for diagnostics of age. It is shown, that a difference between biological and passport age considerably if diagnostics spend on separately taken to object and separately taken attribute. Complex research of the several objects described on the big number of attributes is recommended.

In clause results of an experimental research of factor elasticity various areas of leather of the person on section material are stated. The mathematical analysis of the received data has revealed significant statistically authentic reduction of the specified parameter with the years. The express train-method of diagnostics of age is developed at research of corpses of unknown persons on factor elastmethod of diagnostics of age.

For the purpose of working out of the differentiated approaches to preoperative planning in each specific case on the basis of character estimation of spinal column and spinal cord damage 129 patients (112 men and 17 women) with subaxial damages in the cervical department of backbone have been examined. Morphological peculiarities of cervical vertebrae have been taken into account. The patients have been on treatment at Saratov Scientific Research Institute of Traumatology and Orthopedics from 2004 till 2007. Patients have been properly examined. Volume of surgical intervention from the frontal access and rational choice of implants have been carried out taking into account difficulty and extension of lesions of osseous structures, and morphometry data including in stabilization of vertebrae. The differentiated approach to the choice of implants has allowed in 85-90% cases to receive adequate decompression of neurovascular structures, reliable correction and stabilization of the damaged segment thus it has enabled possible early activization and social rehabilitation of patients of given category.
