Abstract：Objective To compare the clinical efficacy of InterTAN intramedullary nailing and proximal femoral nail antirotation(PFNA)nailing in the treatment of intertrochanteric fracture(IFF).Methods Sixty patients with IFF admitted to our hospital from January 2020 to August 2021 were retrospectively analyzed.According to the operation method,the patients were divided into PFNA group and InterTAN group,with 30 patients in each group.The PFNA group was treated with PFNA nailing,and the InterTAN group was treated with InterTAN intramedullary nailing.The perioperative indicators and pain severity were compared between the two groups.The Harris hip score before operation and at 3,6,and 12 months after operation,the reduction quality at 3 months after operation,and the postoperative complications of the two groups were followed up and recorded.Results The duration of operation of PFNA group was shorter than that of InterTAN group,the intraoperative blood loss was less than that of InterTAN group,and the fracture healing time was longer than that of InterTAN group(P＜0.05,P＜0.01).With the extension of postoperative time,the visual analogue scale(VAS)pain scores of the two groups showed a downward trend,and the VAS scores of the InterTAN group were lower than those of the PFNA group at 1 and 3 d after operation(P＜0.05,P＜0.01).At 3 and 6 months after operation,the Harris scores of InterTAN group were higher than those of PFNA group(P＜0.01).At 6 months after operation,the excellent and good reduction rate in InterTAN group[96.67％(29/30)]was higher than that in PFNA group[76.66％(23/30)](P＜0.05),while the total incidence of complications in InterTAN group[10.00％(3/30)]was lower than that in PFNA group[36.66％(11/30)](P＜0.05).Conclusion InterTAN intramedullary nailing can effectively promote the recovery of hip function in patients with IFF,reduce their postoperative pain,improve the quality of reduction,with good stability and high safety.
