Ogawa T, Yoshii T, Okawa A, et al. - For the vulnerable hip fracture population, recommended treatment is cemented hemiarthroplasty because of beneficial long-term outcomes. However, controversies remain concerning the correlation between cemented hemiarthroplasty and short-term mortality. With the aim to increase a preparedness of potential complication after cemented hemiarthroplasty, researchers herein examined the trajectory of the effect of cemented hemiarthroplasty on short-term in-hospital outcomes. They used a nationwide multicenter database from 2010 to 2016 to investigate in-hospital mortality and complications between cemented hemiarthroplasty and cementless hemiarthroplasty with a propensity-score matching analysis. After matching 31,322 cases, 30-day in-hospital mortality did not differ between the cemented and cementless hemiarthroplasty groups. Overall findings suggest no significant correlation of cemented hemiarthroplasty with an increase in overall in-hospital mortality but it was significantly linked with short-term mortality from 1-day to 10-day after surgery. The cemented group also had significantly higher incidence of stroke and ICU admission. In patients undergoing cemented hemiarthroplasty, they recommend surgeons to pay more attention to the risk of mortality and stroke, especially in the early days of hospitalization.
