RESUMO
OBJECTIVE@#To investigate the effect and feasibility of closed reduction and internal fixation with PFNA in the treatment of intertrochanteric fracture of femur in the supine position without traction bed.@*METHODS@#From June 2014 to March 2018, 45 patients with intertrochanteric fracture of femur who were treated and followed up were analyzed retrospectively. There were 21 males and 24 females, with an average age of 67.4 years (43 to 92 years);18 cases on the left side and 27 on the right side. According to Evans Jensen classification, there were 7 patients of type Ⅱ, 17 patients of type Ⅲ, 16 patients of type Ⅳ and 5 patients of type Ⅴ. The time from injury to operationwas 2 to 6 days. The operation time, blood loss and fracture healing, closing time, postoperative complications and Harris score of hip joint were recorded.@*RESULTS@#The operation time of 45 patients was 35 to 80 min, with an average of 52.6 min;the intraoperative bleeding volume was 40 to 110 ml, with an average of 68.7 ml;the hospitalization time was 6 to 11 days, with an average of 8.4 days;the follow up time was 12 to 18 months, with an average of 14.7 months;the internal fixation of 2 patients failed, and 43 patients achieved bony healing;the deep vein thrombosis of the lower extremity in the perioperative period was 1 case, and the inferior vena cava filter was inserted;the internal fixation of 2 patients was cut out, and the hip was renovated. The incidence of complications was 8.9%(4 / 45). At the final follow up, Harris score of hip joint was 56 to 95 (81.30±8.40), including excellent 15 cases, good 26 cases, fair 2 cases and poor 2 cases.@*CONCLUSION@#It is safe and feasible to treat intertrochanteric fracture of femur with closed reduction and anti rotation intramedullary nailing under the bed without traction in a supine position. It has the advantages of small trauma and low complications, and the clinical effect is satisfactory. It is worth popularizing and using in basic hospitals.
