Age variability of massiveness of bones in the forearm at men

Aim: to detect the regularities of age variability of bones in the forearm at adult men. Material and Methods. By the method of a direct osteometry the greatest length and the circle of the middle diaphysis of radial and ulnar bones were determined. The thickness-length index reflecting massiveness of a bone was defined as a percentage of a circle of middle diaphysis to the greatest length of a bone. Results. Age features of the greatest length, the greatest circle of a diaphysis and the thickness-length index of bones in the forearm, and also correlation of the studied parameters with a body length were revealed. Conclusion. The greatest length of radial and ulnar bones changes with age slightly whereas the circle of the middle diaphysis of bones in the forearm significantly increases with age according to the statistics that affects the increase in an index of massiveness of bones

Morphometric analysis of shin bones in different types of human constitution

<p> </p><p><em>Purpose: </em>to detect variability of absolute and relative sizes of shin bones. <em>Materials and methods. </em>Parameters of large and small tibial bones (n=208) of adults aged from 22 to 89 years (118 men and 90 women) have been studied. Osteo- and anthropometry methods have been applied. <em>Results. </em>Sexual dimorphism, age variability and bilateral dissymmetry of morphometric parameters of shin bones compared with anthropometrical parameters have been studied. <em>Conclusion. </em>Absolute and relative parameters of shin bones have been determined by the type of constitution.</p&gt

Morphometric characteristics of the forearm bones in subjects of childhood, adolescence and early adulthood

Objective: to identify patterns of typology, age and variability of bilateral forearm bones in children, adolescents and young adults. Material and methods. The method of direct linear osteometry determined length (maximum length) and circumference (maximum circumference of the diaphysis) size of the bones of the forearm. Calculated thickness-length index as a percentage of the maximum circumference of the diaphysis to the greatest length of the bone. Results. The age characteristics of greatest length, the greatest circumference of the diaphysis and thickness-length index, as well as communication with the studied parameters of body length. Conclusion. The largest relative increase in the parameters identified in the second childhood and adolescence. Thickness-length index with age decreases slightly from 16,82 to 15.28% in the ulna (9%) and from 20,26 to 19,24% at the radius (5%). A direct close and substantial connection between the length and circumference of the bone and medium-reverse thickness-length index of forearm bones with age and body length

Comparative analysis of morphological and topometric parameters of lumbar spine in normal state and in degenerative-dystrophic changes

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

Morphometric justification of algorithm of the choice of method of surgical treatment of dysplastic coxarthrosis

Purpose: to define regularities of variability of bone structures of a hip joint depending on type of dysplastic coxarthrosis and to develop tactics of total endoprosthesis replacement. Objects of research. 106 patients with dysplastic coxarthrosis of varying severity, passing treatment on the basis of Federal State Budget Institution of Saratov Scientific Research Institute of Traumatology and Orthopedics from 2005 to 2014 applying methods X, KT-, MRT-metry variation and statistical methods. Results: According to anatomic features of a hip joint at dysplastic coxarthrosis of various types algorithms of choice of acetabularand femoral components of endoprosthesis, and also tactics of total endoprosthesis replacement in groups of research are developed. Conclusion. The choice of a standard size of an endoprosthesis of a hip joint needs to be carried out taking into account X-ray anatomic features of a hip joint and degree of expressiveness of the dysplastic changes. At dysplastic coxarthrosis of the l-ll types it is necessary to carry out standard total endoprosthesis replacement; at coxarthrosis of the III type —total endoprosthesis replacement in combination with plasticity of a roof of acetabular hollow; at coxarthrosis of the IV type — total endoprosthesis replacement in a combination from the shortening femur osteotomy
