Abstract：Objective To compare curative effect and safety between Inter Tan and PFNA-II system internal fixation in treatment of elderly patients with unstable fracture of femurs haft.Methods A total of 131 elderly patients with unstable fracture of femurs haft admitted during August 2009 and October 2014 were divided into Inter Tan group (n=58, treated with Inter Tan system internal fixation) and PFNA-II group (n=73, treated with PFNA-II system internal fixation).In two groups, surgical conditions and follow-up data were compared, and conditions of surgical safety were evaluated.Results Surgical time, fluoroscopy time and fracture healed time were significantly longer in Inter Tan group than those in PFNA-II group (P<0.05).The differences in Harris scores for hip joint function at different times of follow-up were not statistically significant (P>0.05).In Inter Tan group, 4 patients had iatrogenic lateral proximal fractures during operation during surgery, while 1 patient had iatrogenic lateral proximal fractures during operation in PFNA-II group.In PFNA-II group, 3 patients were required a shorter and smaller nail during surgery because of the implantation difficulty, while none implantation difficulty was found in Inter Tan group.Conclusion Both Inter Tan and PFNA-II system internal fixation in treatment of elderly patients with unstable fracture of femurs haft can achieve good effect.PFNA-II system internal fixation can achieve short surgical time, fluoroscopy time and fracture healed time with less incidence of complication, and physical training at early stage.
