Effect of proximal femoral anti-rotation intramedullary nail assisted by CT three-dimensional reconstruction in the treatment of intertrochanteric fracture of femur:based on the hip joint function and the incidence of complications
Objective To investigate the effect of proximal femoral anti-rotation intramedullary nail(PFNA)assisted by CT three-dimensional reconstruction on hip joint function and the incidence of complications in patients with intertrochanteric fracture of the femur.Methods Ninety-eight patients with intertrochanteric fracture who received treatment at Lianyungang Hospital affiliated to Xuzhou Medical University from January 2020 to October 2022 were included,and they were divided into the control group and the observation group by random number table method,with 49 cases in each group.The control group was treated with conventional PFNA,while the observation group was treated with PFNA assisted by CT three-dimensional reconstruction.Both groups were followed up for 12 months after operation.The clinical efficacy(12 months after follow-up),score of Harris hip(preoperative,postoperative 6 months,postoperative 12 months),thromboelastogram parameters(preoperative,postoperative 7 d),serum factors(preoperative,postoperative 3 months)and complications(during the study period)were compared between the two groups.Results After a follow-up of 12 months,the total effective rate in the observation group was 97.96%,which was higher than that in the control group(85.71%)(P<0.05).Compared with before operation,score of Harris hip increased in both groups from 6 to 12 months after operation,especially in the observation group(P<0.05).Compared with before operation,on 7th day after operation,coagulation reaction time and coagulation formation time in both groups shortened,the observation group was shorter,while blood clot formation rate increased,and the observation group was larger(P<0.05).Compared with before operation,3 months after operation,the levels of serum D-dimer in both groups decreased,and the values of serum prothrombin time were all shortened,and the levels of serum bone morphogenetic protein-2 and transforming growth factor-β1 all increased,the observation group was higher(P<0.05).During the study period,there was no significant difference in the total incidence of complications between the two groups(P>0.05).Conclusion PFNA treatment for patients with intertrochanteric fracture assisted by CT three-dimensional reconstruction could effectively improve the level of fracture healing factors,improve the coagulation function and thromboelastogram parameters of patients,and promote the recovery of hip joint function,with good safety and remarkable curative effect.
