The pattern of recovery of ambulation after hip fracture differs with age in elderly patients.
BACKGROUND
The main objective of this study was to analyze the independent effect of increasing age on the recovery of different areas of functioning 1 year after hip fracture.


METHODS
Consecutive 1-year survivors aged ≥ 65 years (n = 362) admitted to a single hospital for acute hip fracture surgery were followed prospectively for 1 year. Age was stratified as <75, 75-84, and ≥ 85 years. Basic activities of daily living and ambulation were measured by personal interview during hospitalization and phone contact at 3, 6, and 12 months. Longitudinal data of recovery in these areas were analyzed using generalized estimating equations.


RESULTS
Older age was strongly associated with poor recovery in all areas of function, except eating. The pattern of recovery of ambulation differed with age, peaking at 6 months in the younger group and continuing for at least 12 months in the eldest group. The pattern of recovery of overall and individual activities of daily living was similar in the three age groups. Recovery of areas associated with upper extremity function peaked at 3 months, whereas areas associated with lower extremity function peaked at 6 months.


CONCLUSIONS
The patterns of functional disability after hip fracture differ with areas of function and age with the oldest patients having a particular risk of decline and a prolonged time to recovery of ambulation.
