[Femoral neck prosthesis in elderly subjects].

In the article are presented data, based on the research analysis, corroborating the necessity of creation of individual joint surfaces of single-pole endoprostheses of hip joint. There are presented the descriptions of the endoprosthesis, proposed by T. Kikacheishvily and the operative technique with application of the said construction.

[Diagnosis of spinal fractures using optical processing of the roentgenologic image].

X-ray examinations by a traditional method in 694 patients with non-complicated compression fractures in the thoraco-lumbar part of the vertebral column do not always give the exact picture of the character of fractures of the vertebral column. The method of optic processing the roentgen picture was used in 30 patients for more detailed analysis of structural changes in the vertebrae bodies. The method allowed to specify structural changes in the vertebra bodies, including the detection of the fracture plane, abruption of a body portion, detection of an additional contour of the limiting plate in its pressing into the vertebra body and the zone of infiltration in the upper portions of the body.

[Repair of bone defects with a polymer material].

Experimental investigations and results of 76 clinical observations of patients with endoprostheses made of Acryloxide enabled the authors to support grounds for using the compositional polymer material Acryloxide for the substitution of defects formed after resections for neoplasms.

[Clinical and experimental bases for the use of Acryloxide in restorative surgery of the joints].

Experimental and clinical investigations showed good prospects of further studies of deformation characteristics of Akryloxide, particularly the elasticity module to judge of the degree of biological destruction of the plastics and possible prognosis of working efficiency of the polymer in individual endoprosthesis of joints.
