Application of traction bed combined with direct prying"key point"reduction method in internal fixation of AO/OTA-A1 irreducible femoral intertrochanteric fractures of femur
Objective To observe the effect of traction table combined with direct prying"key point"reduction method in the internal fixation of AO/OTA-A1 irreducible femoral intertrochanteric fractures of femur.Methods A retrospective analysis was performed on 40 cases of intertrochanteric femoral fractures diagnosed and treated from January 2020 to December 2022,which were divided into two groups according to fracture reduction.Group A was easily reducible intertrochanteric fractures of femur,which were easily reduced during closed reduction by traction,adduction and internal rotation on the traction table.Group B consisted of irreducible intertrochanteric fractures,which could not be reduced satisfactorily by traction,adduction or internal rotation on the traction table,so the traction table combined with direct"key point"was used for fracture reduction.The proximal femur combined with interlocking intramedullary nail(InterTan)was used for internal fixation in both groups.Opera-tion time,intraoperative blood loss and Harris score of hip function 3 months after operation were compared between the two groups.Results All patients were followed up for more than 3～5 months,with an average of 3.6 months.There was no vascular injury during operation and no incision infection after operation.There was no statistical difference in operation time between the two groups(t=-1.483,P=0.142).There was no significant difference in intraoperative blood loss between the two groups(t=1.747,P=0.089).There was no statistical difference in the Harris score of hip function 3 months after surgery between the two groups(t=0.498,P=0.567).Conclusion Traction table combined with direct prying key point reduction method in AO/OA-A1 irre-ducibe femoral intertrochanteric fractures achieves good reduction effect and satisfactory clinical efficacy.
