title: Early clinical results of cementless, bipolar hemiarthroplasty in intracapsular femur neck fractures.
abstract: OBJECTIVE
  In this study we report our initial experience with the use of cementless, bipolar hemiarthroplasty in elderly patients with intracapsular femur neck fractures.
  
  
  METHODS
  We operated 67 consecutive patients (39 females, 28 males; mean age 74.4±11.0 years; range 41 to 99 years) who admitted to our clinic June 2007 and November 2009, due to intracapsular femur neck fracture and implanted cementless, rectangular, dual-taper, straight femoral stem (Zweymüller stem) with bipolar head prosthesis. All patients were allowed to full weight bearing with a walker within the first postoperative 48 hours.
  
  
  RESULTS
  According to the Garden's classification, there were nine type II, 53 type III and five type IV fractures. Twelve patients were lost to follow-up and 21 deceased during the postoperative follow-up period. Among 34 patients with complete follow-up, 30 were evaluated for the clinical outcome. The mean follow-up time and Harris hip score of the evaluated patients were 19.4 months and 79.4 points, respectively. It was seen that, the patient age significantly correlated with the clinical outcome and a better mean hip score was obtained in the '70 years and younger age group' (83.6 points) as compared to the 'older than 70 years age group' (75.6 points) (p=0.014). Mortality rate was found to be higher in patients older than 70 years (47% vs. 18%; p=0.036) and with displaced fractures (45% vs. 0%; p=0.018).
  
  
  CONCLUSIONS
  Zweymüller cementless bipolar hemiarthroplasty may be an alternative treatment method for intracapsular femur neck fractures especially in the patients under the age of 70 years.
