The aim of this study was to examine the influence of weight-bearing
(WB) status after hip fracture surgery on 1-yr functional outcome. DESIGN: This
was a prospective cohort study, carried out in a public acute hospital trauma
service. The 194 patients (36 men and 158 women), with a mean (SD) age of 81.4
(6.1) yrs, were admitted with a hip fracture within 2009 and were followed for 1
yr thereafter. The influence of postoperative WB status on the 1-yr functional
outcome was assessed using the Functional Independence Measure (18-126 points),
adjusting for other known factors by multiple linear regression. RESULTS:
Seventy-five patients (39%) were not allowed WB for a period of 2-4 wks after
surgery. Improved functional outcomes were associated positively with prefracture
functional level and having a trochanteric fracture during the first year after
fracture (P </= 0.01). Non-WB status, age, health status, and cognitive
impairment of the patient were associated negatively with the 1-yr functional
outcome (P </= 0.03). Prefracture functional level and non-WB status were the
strongest determinants of functional level (beta = 0.599 and -0.204,
respectively; P < 0.001). CONCLUSIONS: WB status after surgery, in addition to
prefracture function, cognitive status, health status, age and fracture type, was
found to be an independent predictor of the 1-yr functional outcome in hip
fracture patients.
