[Clinical observation of different intramedullary fixation methods for the treatment of intertrochanteric fracture].
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 significant difference between PFBN group and InterTan group ( P >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.
