title: Early experience of dynamic hip screw with spiral blade and locking side plate for the stabilization of trochanteric fractures.
abstract: OBJECTIVE
  To evaluate early experience with helical hip system in osteoporotic elderly patients with per-trochanteric fractures.
  
  
  METHODS
  The retrospective study was conducted at Aga Khan University Hospital, Karachi, and comprised records of patients having low-velocity pertrochanteric fractures who were fixed with spiral blade Dynamic Helical Hip Systemfrom July to December 2014 and were followed up for a minimum of 3 months. Demographic variables and clinical outcomes were noted from the medical records whereas operative details were recorded from the operative note. Radiological variables and outcomes were assessed by viewing appropriate pre-operative, post-operative and follow-up radiographs.
  
  
  RESULTS
  Of the 32 patients in the study, 14(44%) were men and 18(56%) were women, with an overall mean age of 77.81±7.04 years and mean body mass index of 25.99±4.13 kg/m2. Of the total, 1(3.13%) patient had implant cut-out, 1(3.13%) had myocardial infarctionand 2(6.2) expired.
  
  
  CONCLUSIONS
  The introduction of spiral blade dynamic hip screw manifested favourable results and good clinical and radiological outcomes with low cut-out rates.
