ABSTRACT
Objective To analyze the long-term effect and prognosis of automatic angle measuring instrument in measuring anteversion angle of patients with total hip arthroplasty(THA).Methods A total of 120 patients with THA from June 2012 to January 2017 were divided into two groups by random number table,with 60 cases in each group.The anteversion angle of THA in control group was measured by CT, while the anteversion angle of THA in observation group was measured by automatic angle measuring instrument.The recovery of hip joint, score of living quality,incidence of complications before and after surgery were compared between the two groups. Results After surgery,the score of hip joint recovery in control group was lower than that in observation group,the difference was significant(P<0.05).After surgery, the scores of living quality in two groups increased compared with those before surgery,and the increased range of observation group was lar-ger,the difference was significant(P<0.05).The incidence of complications in control group was 13.33% ,which was higher than 1.67% of observation group,the difference was significant(P<0.05). Conclusion Automatic angle measuring instrument in measuring anteversion angle of THA can increase measuring accuracy,decrease the incidence of complications,increase living quality and promote prognosis,which is worthy of promotion in clinical application.
