Abstract:
Objective To explore clinical efficacy of proximal femoral nail anti-rotation(PFNA),InterTan and proximal femoral bionic intramedullary nail(PFBN)in treating femoral intertrochanteric fracture.Methods Clinical data of 120 patients with intertrochanteric fracture who were underwent closed reduction intramedullary nail-internal fixation from January 2020 to January 2021 were retrospectively analyzed.According to methods of internal fixation,patients were divided into 3 groups.There were 25 patients in PFBN group,including 16 females and 9 males,aged from 69 to 79 years old with an average of(73.67±5.16)years old.There were 55 patients in PFNA group,including 38 females and 17 males,aged from 68 to 80 years old with an average of(74.23±5.57)years old.There were 40 patients in InterTan group,including 26 females and 14 males,aged from 68 to 79 years old with an average of(73.45±5.34)years old.Operative time,intraoperative blood loss,incision length,hospital stay,weight-bearing time,fracture healing time and complications among 3 groups were compared,and clinical effect was evaluated by Harris score of hip function before operation,1,6 and 12 months after opertaion,respectively.Results Patients among 3 groups were successfully completed operation and were followed up for more than 12 months.There were no significant difference in hospital stay,operative time,intraoperative blood loss and incision length among 3 groups(P＞0.05).Weight bearing time of PFBN group(7.98±1.34)d and InterTan group(8.22±0.46)d were earlier than that of PFNA group(10.27±0.66)d(P＜0.01).Fracture healing time of PFBN group(10.14±2.33)weeks and InterTan group(11.87±2.48)weeks were earlier than that of PFNA group(13.68±2.36)weeks(P＜0.01).One month after operation,Harris score in PFBN group(70.52±5.34)and InterTan group(69.81±6.17)was higher than that of PFNA group(51.46±5.36),and there was no signifi-cant difference between PFBN group and InterTan group(f＞0.05).There were no significant difference in Harris scores among 3 groups before operation,6 and 12 months after opertaion(P＞0.05).Cases of complication of InterTan group and PFNA group were lower than that of PFNA group(P＜0.05).Conclusion PFBN and InterTan for the treatment of intertrochanteric fracture have advantages of faster fracture healing,earlier weight-bearing time and fewer postoperative complications than traditional PFNA,but three operations could achieve higher effective rates without significant difference in long-term results.
