[Biorhythmic characteristics of patients with total primary and revision hip replacement].

Age-dependent fluctuations of primary total and revision endoprosthesis have been found which appear to reflect changes in the activity of the inflammation process that can be regarded to be an element of periodic diseases. This seems to depend on the regulatory-metabolic shifts caused by aging.

[The limits of fluctuations of the laboratory findings in the preoperative period during uncomplicated revision endoprosthesing of the hip joint]. / Predely kolebanii laboratornykh pokazatelei v predoperatsionnom periode pri neoslozhnennom revizionnom éndoprotezirovanii tazobedrennogo sustava.

The revision endoprosthesis of the hip joint for aseptic loose components was performed in 482 patients (297 women and 185 men). Before operation the assessment of 44 laboratory indices was made which included clinical blood tests, investigation of the coagulating system, protein and mineral exchange, enzymatic activity and other biochemical criteria. The postoperative course was even, without variations. The work shows the limits of deviations of the parameters with respect to normal condition and gender. The authors believe that they can be considered as a variant of the clinically adequate reaction rather than as a criterion of the unfavorable prognosis of the postoperative course.
