Summary:

Objective: to carry out comparative analysis and identify patterns of topographic variation patterns of lumbar spine in normal and degenerative changes. Material and methods. CT- and MRT-grams for men and women I (M1-22-35 years; W — 21-35 years) and II (M2-36-60 years; W2-36-55 years) periods of mature age with no signs of trauma, scoliosis and systemic diseases of the spine (n=140) and CT- and MRT-grams in patients with revealed degenerative changes in the lumbar spine degree II-III (n=120). The pictures with digital PACS system measure the height of the vertebral body, intervertebral disc height, vertical, horizontal diameter and the area of intervertebral foramen. Results. The height of the lumbar vertebral bodies normally increased from27,90±0,38mmatthe level of L, to 29,93±0,33 mm Lm, and then decreased to 24,35±0,27 mm at level L^, in osteochondrosis it is statistically significantly lower at all levels on average by 20%. The height of the intervertebral disc with osteochondrosis below at all levels by an average of 25% of its value in the range 5,27±0,19 to 6,13±0,17mm, while the normal disc height varies from 6,88±030 to 9,36±0,28mm. The area of intervertebral holes normally ranging from 103,29±5,78 to 127,99±5,92mm2, with osteochondrosis aperture area is reduced to a greater extent by decreasing the vertical diameter in comparison with the horizontal. Conclusion. For the studied parameters characteristic topographic variability has been determined. The maximum values parameters are marked at the top of the lumbar lordosis, at chest height, lumbar and lumbosacral junctions sizes are reduced. In osteochondrosis the intervertebral disc height and the height of lumbar vertebral bodies are reduced; intervertebral foramina area is also reduced to a greater extent by reducing the vertical diameter than the horizontal one.

Individual and typological morphogeometric features of the proximal of femoral bone

Year: 2010, volume 6 Issue: №1 Pages: 036-039

Summary:

The aim of this study was to examine the relationship between the structure of the proximal femur and its individual anatomical variability, namely the size of the femoral neck and the angle of torsion. These results suggest that the mor-phogeometry of the femur (the femoral neck axis length and width of the neck) may influence on the risk of fractures of the femoral neck in people of different body type

Individual And Typical Anatomical Variability Of Femoral Bone Structure And Morphology Of Nutrient Foramen

Year: 2009, volume 5 Issue: №4 Pages: 485-488
Heading: Macro- and Micromorphology Article type: Original article
Authors: V.N. Nikolenko, O.A. Fomicheva, R.S. Zhmurko, N.M. Yakovlev, O.S. Bessonova, S.V. Pavlov
Organization: Saratov State Medical University
Summary:

45 morphometric parameters of femoral bones (n=45) have been studied. Their 3 shape variants have been picked out according to thickness-prolixity index. The peculiarities of entry angle of diaphysial artery in connection with the bone shape have been revealed. Zones of the most and the least concentration of nutrient foramen have been determined
