Brief Summary:

Hemiarthroplasty (half of a hip replacement) is the most common treatment for displaced fractures of the femoral neck in the elderly and is associated with a better functional outcome and fewer reoperations than internal fixation. Currently, the operative management of displaced femoral neck fractures favors the use of cemented implants. This technique is believed to be more stable in the immediate post-operative period, but there is limited evidence of a decreased morbidity and mortality with cemented versus press-fit stems (uncemented). In 2006, a meta-analysis concluded that the evidence was too limited to recommend a cemented or press-fit hemiarthroplasty.

In this investigation, the morbidity, mortality and functional outcome associated with cemented and press-fit hemiarthroplasty will be compared prospectively. We propose that the use of press-fit hemiarthroplasty in the treatment of displaced subcapital fractures of the femoral neck would be associated with a decreased risk of adverse peri-operative outcomes, and that the functional results of cemented and press-fit hemiarthroplasty will be equivalent at one year.

Arm Intervention/treatment
Cemented Hip Hemiarthroplasty
This arm received a hemiarthroplasty with a cemented femoral prosthesis (VerSys LD/Fx, Zimmer, Warsaw, IN).
Device: Cemented Hip Hemiarthroplasty
The cemented femoral prosthesis is a VerSys LD/Fx, Zimmer, Warsaw, IN.

Experimental: Press-Fit Hip Hemiarthroplasty
This arm received a press-fit hemiarthroplasty (VerSys Beaded FullCoat, Zimmer, Warsaw, IN),
Device: VerSys Beaded FullCoat, Zimmer

Primary Outcome Measures :
  1. Mortality [ Time Frame: 1 year ]
    Assessment of post-operative mortality at one-year.

  2. Post-Operative Unstable Angina [ Time Frame: 1 week post-operation ]
    Unstable angina was defined as the new onset of prolonged chest pain (greater than or equal to 30 minutes) or two episodes of chest pain thought to be of cardiac origin or an electrocardiogram showing new T-wave inversion, ST depression or elevation with enzymes non-diagnostic of myocardial ischemia.

  3. Post-Operative Myocardial Infarction [ Time Frame: 1 week post-operation ]
    Myocardial infarction required a positive troponin or electrocardiogram consistent with definite infarction.

Secondary Outcome Measures :
  1. Instrumental Activities of Daily Living (IADL) and Physical Activities of Daily Living (PADL) scale [ Time Frame: 1 year ]
    A modified version of the Older Americans Resources and Services Instrument (OARS) which asks about performance of tasks of daily living during the preceding two weeks.14 These activities include: getting to places, walking distances, shopping for groceries or clothes, preparing meals and doing housecleaning.

  2. Energy/Fatigue Scale [ Time Frame: 1 year ]
    An inquire about fatigue, level of energy and self-efficiency.
