Functional Status, Morbidity and Mortality in Cemented Versus Uncemented Hemiarthroplasty for Subcapital Hip Fractures: A Prospective Randomized Trial
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.
