Objective According to the assessment results of Norton Scale at admission, to evaluate the prognostic of Norton Scale on postoperative complications after total hip arthroplasty (THA) in elderly patients, and to guide clinical practice. Methods A prospective study was conducted. Selected the quasi for THA in elderly patients as the research object. The patients were divided into low Norton group(total scale score≤14 points, 28 cases) and high Norton (total scale score≥15 points, 125 cases) according to the Norton Score. Postoperative complications after THA between the two groups were compared. Results The postoperative complications of wound infection, urinary tract infection, urinary retention, bedsore and deep vein thrombosis after THA was 32.1%(9/28), 17.9%(5/28), 10.7%(3/28), 10.7%(3/28), 14.3%(4/28) in low Norton group and 2.4%(3/125), 1.6%(2/125), 1.6%(2/125), 0.8%(1/125), 1.6%(2/125) in high Norton group, and there was significant difference (P<0.05). Logistic regression analysis showed that low Norton were independently associated with postoperative complications (P<0.05), the probability model of judgment after total hip replacement surgery complications accuracy was 86.9%, sensitivity was 96.5%, specificity was 60.0%. Conclusions In addition to predicting pressure ulcer risk, the Norton Scale may be used to predict the incidence of postoperative complications in elderly patients with THA.
