Functional outcome after hip fracture. Effect of general versus regional anesthesia.

The effect of anesthetic technique on ambulation and functional recovery after hip fracture was studied in a series of 631 community dwelling, elderly patients. Functional recovery at followup was determined by an 11-item functional rating scale. In univariate analysis, recovery of ambulatory ability and percent functional recovery were significantly higher at 6 months for patients who had general anesthesia. When controlling for potential confounding variables, however, no differences were observed in recovery of ambulatory ability or percent functional recovery between the two groups at 3, 6, or 12 months after hip fracture.
