PROGNOSIS OF DEEP INFECTIOUS COMPLICATIONS IN HIP ARTHROPLASTY

The retrospective research analyzed the data of 893 patients undergoing total hip arthroplasty. There were used the data about patients undergoing hip arthroplasty without complications (the first group--808 cases) and patients with developed deep surgical site infection following total joint arthroplasty after 12 months (the second group--85 patients). It was applied as the training matrix in creation of mathematical prognosis and algorithm of prophylaxis of deep infection in patients undergoing the primary total hip arthroplasty. There were revealed 21 prognostic significant criteria of deep infection development in surgical site. The program was tested in prospective investigation (293 clinical cases) with follow-up term of 12 months after operation. The rate of development of postoperative deep infection in surgical wound reduced as compared with the rate in group of retrospective research from 1.7% to 0.7%. The efficacy of proposed program was 80%.
