title: Five-Year Outcome Analysis of Intertrochanteric Femur Fractures: A Prospective Randomized Trial Comparing a 2-Screw and a Single-Screw Cephalomedullary Nail.
abstract: OBJECTIVE
  To compare the radiological and functional outcome after fixation of intertrochanteric fractures (IF) using either an integrated 2-screw cephalomedullary nail [InterTan (IT); Smith & Nephew] or a single-screw device [Gamma3 (G3); Stryker] with a 5-year follow-up.
  
  
  METHODS
  Prospective, randomized.
  
  
  METHODS
  A single-center study.
  
  
  METHODS
  One hundred four patients with a mean age of 81.2 ± 9.2 years were included, 33 patients were available for the final 5-year follow-up, 63 patients died, and 8 patients were lost for follow-up.
  
  
  METHODS
  Internal fixation of intertrochaneteric femur fractures using a cephalomedullary nail with either a single screw or an integrated 2-screw system.
  
  
  METHODS
  Length of hospital stay, SF-36-questionnaire, Harris-Hip-Score, radiographs.
  
  
  RESULTS
  SF-36 index at 6 months indicated that 93% of the IT group returned to their prefracture status compared with only 80% in the G3 group. For the mental health SF-36 index, the IT patients showed a significant increased level 6 months after the index procedure (IT: P = 0.02; G3: P = 0.20). The length of hospital stay was significantly (P = 0.03) shorter in the IT group. After 5 years however, neither group had significant implant-related complications or differences in terms of functional outcome.
  
  
  CONCLUSIONS
  Regarding functional outcome and hospital stay, the IT collective performed better in the 6-month follow-up. After 5 years, no significant differences were recorded.
