[Somatometric and impedance measurements of the lower extremities in orthopedics].

Purpose Of The Study: The objective was to demonstrate the contribution of somatometry and vascular impedance measurement to the evaluation of somatic status and nutrition, particularly the state and function of the vascular system of lower extremities, in patients with arthropathy of the weight-bearing joints.

Material: Impedance plethysmography and impedance phlebography appeared to be the best methods for assessment of vascular hemodynamics; pulse oxymetry, carried out on toes, was most convenient for measurement of haemoglobin saturation with oxygen (HbO2). The state of vessels was determined according to the CEAP classification.

[Somatometric and Hemodynamic Measurements after the Total Replacement of Weight Bearing Joint in Preventive Administration of Low-molecular Heparines.].

The authors present outcomes of simple somatometric and impedance measurements of the condition of venous hemodynamics after the total replacement of weight bearing joints with a simultaneous prophylactic application of low molecular heparines (LMH). Measurements in a group of 125 patients (86 females and 39 males) showed increase of circumferences up to symptoms of a swelling on proximal portions of the limb operated on in an early postoperative period; as a rule it reached its peak between 6th and 8th day with a subsequent subsidence in the next period, i. e.

[Osteoarthropathies and conditions after alloplasties of the knee joints from the aspect of antropometric examinations.].

The authors submit an analysis of the nutritional status assessed by anthropometric methods in a clinical group of 70 patients (mean age 58 years) where on account of the X-ray and the clinical finding of arthritis of the knees an alloplastic operation was performed. The results of the examination are compared with the analysis of the nutritional status of a group of 20 without X-ray and clinical signs of arthritis of the knee. The patients belonged to a similar age bracket.

[Advantages of digitalization and analysis of roentgenograms of bones by microcomputer.].

The creation of an experimental group for digitalization of two-dimensional X-ray pictures of bones was the starting point for the application of selected procedures for their computer-assisted analysis. During processing of the picture first the primary digitalized picture was corrected (e. g.

[Methods of evaluating nutritional status in preventive screening of the population].

After selecting anthropometric parameters for preventive examinations of the population and elaborating a computer program, the authors analyzed a series of 1000 probands with respect to their nutritional state. The occurrence rate of latent and clinically manifest obesity was in the given series 22.70% in men and 15.
