Analysis of the Efficacy of Bone Grafting Through the Channel by Vertebroplasty Instrument Combined with PFNA in the Treatment of Senile Intertrochanteric Fracture
Objective:To explore the effect of implanting artificial bone through the channel by vertebroplasty instrument combined with minimally invasive proximal femoral nail antirotation(PFNA)internal fixation for senile intertrochanteric fracture of femur.Methods:69 elderly patients with intertrochanteric fracture of femur from June 2020 to December 2021 were divided into two groups.Patients were treated with PFNA and bone grafting combined with PFNA internal fixation respectively,and blood loss,operation time and clinical union time were compared between the two groups,patients'satisfaction at 3 months after operation,and incidence of complications(coxa vara after weight bearing)were compared.Results:69 patients in the two groups were followed up for 12 to 18 months(mean 15 months).There was no statistically significant difference in intraoperative blood loss and operation time between the two groups(P>0.05),the difference in clinical union time was statistically significant(P<0.05).There were statistically significant differences in patient satisfaction and complication incidence at 3 months after surgery(P<0.05).Conclusion:Intramedullary fixation has achieved good results in the treatment of intertrochanteric fractures of the femur in the elderly,and implanting artificial bone through the channel by vertebroplasty instrument is minimally invasive and simple during operation,which has a better effect for patients with severe osteoporosis.
