DIAGNOSTIC TECHNIQUE FOR SUBACUTE PYOINFLAMMATORY PROCESS IN ENDOPROSTHESIS REPLACEMENT Russian patent published in 2012 - IPC G01N33/49 

FIELD: medicine.

SUBSTANCE: invention describes a diagnostic technique of subacute pyoinflammatory process in endoprosthesis replacement, involving evaluating preoperative phagocytes differing by the fact that phagocytic activity of neutrophils is calculated in the patients in 12-24 months after the implantation and provided: PI (a phagocytic index) makes 81.0-92.0%, IPC (an index of phagocytosis completeness) - 65-77%, APC (active phagocyte count) - 2.6-3.1 (10⁹/l), the derived data are estimated as an unstable endoprosthesis with no signs of the pyoinflammatory process; the PI makes 92.0-94.5%", IPC - 60-64%, APC - 3.3-3.6 (10⁹/l), the derived data are estimated as an unstable endoprosthesis with signs of the subacute pyoinflammatory process.

EFFECT: method allows detecting the remote process of developing implant instability, both with signs, and with no signs of the pyoinflammatory process.
