Hip fractures in centenarians.

The centenarian population is increasing yet there is little about their morbidity and mortality rates following hip fracture. The aim was to review centenarians treated for proximal femoral fractures in Edinburgh describing treatment outcomes in relation to mortality, walking ability and residential status comparing centenarians with a the more typical hip fracture population. In this retrospective review, 18 centenarians sustaining hip fractures in Edinburgh between 1998 and 2002 were compared to 18 randomly selected "normal" hip fracture patients aged 75-83 years. Centenarian in-hospital, 1 and 4 month mortality was 11.1, 33.3 and 50%, respectively, versus 0, 0 and 5.6% in the normal group. Centenarian 4 month mortality was significantly greater than that of the normal group (Fisher's Exact Test, P = 0.00723). A total of 22.2% of centenarians regained pre-fracture walking ability compared to 58.8% of the normal patients. A total 28.6% of centenarians could continue living independently post-fracture compared to 69.2% of the normal group.
