ABSTRACT

Objective To compare the long term efficacy of total hip arthroplasty and half hip arthroplasty in the treatment of elderly patients with femoral neck fracture .Methods 70 elderly patients with femoral neck fracture who needed hip replacement were randomly divided into the observation group and control group ,35 cases in each group.The observation group was given total hip arthroplasty ,while the control group was given half hip arthroplasty . The postoperative long term effect was compared between the two groups .Results The overall incidence rate of post-operative infection of the observation group was higher than the control group ,the postoperative revision rate of the ob-servation group was lower than the control group ,but the differences between the two groups were not statistically sig-nificant(P>0.05).The overall incidence rate of postoperative chronic pain in the control group was 22.86%,which was higher than 2.28%of the observation group,the difference was statistically significant (χ2 =5.130,P<0.05). The postoperative Harris score of the observation group was (93.25 ±4.51)points,which was significantly higher than (82.76 ±3.82)points of the control group,the difference was statistically significant (t=6.973,P<0.05).The ex-cellent and good rate of the observation group was 91.43%,which was significantly higher than 71.43%of the control group,the difference was statistically significant (χ2 =6.492,P<0.05).Conclusion Total hip arthroplasty in the treatment of femoral neck fracture can reduce the incidence of postoperative pain ,improve hip function of the patients , and its long-term effect is better than single hip replacement surgery ,which should be widely applied in clinical .
