title: [A long-term study regarding the therapeutic effect of two titanium screw fixation for femoral neck fractures].
abstract: OBJECTIVE
  To observe the long-term efficacy of two double-head compression titanium screw anterior and posterior cross internal fixation on femoral neck fracture.
  
  
  METHODS
  A total of 80 patients with the femoral neck fracture, from January 2010 to December 2013 in the Second Xiangya Hospital, Central South University, were selected and divided into an experimental group (n=50) and a control group (n=30). Th e experimental group received the treatment of two compression titanium screw anterior and posterior internal fixation, while the control group received three titanium screw internal fixation. Surgery time and intraoperative blood loss and postoperative Harris hip score were compared between the 2 groups.
  
  
  RESULTS
  Th e operative time in the experimental group was (41.6±6.4) min, which was shorter than that in the control group [(50.1±7.2) min], the postoperative bleeding loss was (20.2±8.1) mL, which was less than that in the control group [(31.4±9.8) mL], with significant difference (both P<0.05). The excellence rate of Harris hip score was 94.0% in the experimental group, while that in the control group was 93.3%, with no significant difference (P>0.05).
  
  
  CONCLUSIONS
  Two double-head compression titanium anterior and posterior cross internal fixation shows a good long-term efficacy on femoral neck fracture, which holds important clinical value and should be widely spread.
