| Objective:To compare the clinical outcomes with Inter TAN vs PFNA or PFNA-Ⅱ in the treatment of unstable intertrochanteric fractures in elderlyethod.Methods:The databases of Cochrane,Embase,Pub Med,and CNKI,Wanfang and VIP were searched,and the literatures comparing Inter TAN vs PFNA or PFNA-Ⅱ for the treatment of elderly unstable intertrochanteric fractures were searched.The search period was from December to December 2019.Two reviewers independently read and screened the literature,extracted the data,and evaluated the quality.Meta-analysis was performed using Rev Man5.3 software.Results:A total of 1349 patients were included in 8 studies.Meta analysis results show that Inter TAN is not significantly different from PFNA in terms of operative time and fluoroscopy time,and is longer than PFNA-Ⅱ;Inter TAN internal fixation is used in screw removal after surgery,hip and thigh pain,femoral shaft fractures,and secondary surgery.It is better than PFNA and PFNA-Ⅱ,and there is no significant difference between Inter TAN and PFNA and PFNA-Ⅱin intraoperative blood loss,length of hospital stay,and Harris score after operation.Conclusion:For patients with osteoporosis and poor stability,Inter TAN can provide better stability and reduce postoperative complications;for patients with poor general conditions and greater risk of surgery,PFNA-Ⅱ internal fixation can be selected. |
