METHOD FOR SETTING DIFFERENTIAL DIAGNOSIS OF ASEPTIC NECROSIS OF FEMUR HEAD AND DEFORMING ARTHROSIS OF HIP JOINT Russian patent published in 1998 - IPC

FIELD: medicine. SUBSTANCE: method involves making analysis of clinical manifestations and X-ray examination data, taking blood samples and dividing it into plasma and erythrocytes, measuring concentration of malonic dialdehyde (MDA) separately in plasma and erythrocytes, calculating MDA MDA_p index as ratio of determined value of MDA concentration in plasma to the like value observed in healthy people. MDA MDA_er is defined as ratio of measured MDA concentration in erythrocytes to averaged value of the index in healthy people. MDA MDA_s is defined as sum of MDAMDA_p and MDAMDA_er. The values of MDAMDA_s being equal to or greater than 1.85, aseptic femoral head necrosis is diagnosed. MDAMDA_s being equal to or less than 1.84, coxarthrosis is diagnosed. EFFECT: enhanced effectiveness and reliability of diagnosis. 1 tbl
