Title: The Effect of a Pre- and Postoperative Orthogeriatric Service. A Randomised, Controlled Trial
Brief Summary: The investigators' aim is to assess the effect of a model of preoperative as well as early postoperative care, treatment and rehabilitation in a dedicated orthogeriatric ward in a single-blind randomised study.

The investigators' main hypothesis is that an orthogeriatric service may improve long-time cognitive outcome.
