Comparison of artificially double-acting avascular replacement and PFNA internal fixation for intertrochanteric fractures in elderly patients / 局解手术学杂志

ABSTRACT

Objective To observe the clinical efficacy of bipolar hemi arthroplasty and PFNA internal fixation for elderly patients with unstable intertrochanteric fracture.Methods The data of 79 elderly patients with unstable intertrochanteric fracture in our hospital from Au-gust 2013 to August 2014 were analyzed retrospectively.According to different surgical methods,79 cases were divided into observation group (n =40)and control group(n =39).The observation group were treated by artificially double-acting avascular replacement,and the control group received PFNA internal fixation.The operation time,intraoperatve blood soss,bedridden time,clinical effecacy and complications were recorded and observed.Results The operative time and bed time of observation group were significantly shorter than those of control group, the difference was statistically significant(P <0.05).The total postoperative complication rate of observation group was 20.00%,which was higher than 20.51% of control group,the difference was statistically significant (P <0.05).The Harris scores in observation group 3 months and 6 months after surgery were significantly higher than those in control group,the differences were statistically significant(P <0.05).Con-clusion Both artificially double-acting avascular replacement and PFNA internal fixation have a good effect on elderly patients with unstable intertrochanteric fracture.The artificially double-acting avascular replacement has the advantages of less blood loss,faster recovery and less postoperative complications,which is conducive to improving the quality of life of patients.
