|ABSTRACT Objective: To investigate the mid-term effect of biotype elongated handle joint replacement in the treatment of unstable intertrochanteric fracture of femur in the elderly.
Method：From January 2015 to January 2018, 64 cases of elderly patients with unstable intertrochanteric fracture of femur undergoing surgical treatment, according to the treatment,the patients were divided into arthroplasty group(biotype elongated stipe joint replacement) and internal fixation group(PFNA). The operation time,blood loss and complications were analyzed,followed-up observation was carried out,Harris hip function score and SF-36 quality of life score were recorded for clinical evaluation.
Resuts: All patients were followed up effectively,time 13-39 months,average 23.4 months.The operation time and bleeding volume in the arthroplasty group were more than those in the fixation group,and the difference was statistically significant(P＜0.05). Comparison of postoperative complications, intermuscular venous thrombosis occurred in 1 case and posterior dislocation occurred in 1 case in the arthroplasty group,and in the internal fixation group,there were 1 case of nonunion of fracture,2 case of intermuscular venous thrombosis,4 cases of mild pressure ulcer and 2 cases of loosening of internal fixation, and the difference was statistically significant(χ2=4.929，P=0.026).The Harris function score of hip joint in arthroplasty group was better than that in internal fixation group, the difference was statistically significant(P＜0.05). The SF-36 quality of life score in arthroplasty group was better than that in internal fixation group, the difference was statistically significant(P＜0.05).
Conclusion:The treatment of unstable femoral intertrochanteric fracture with biolengthened handle arthroplasty has fewer complications,better recovery of hip function and higher quality of life.
