Description
Summary:INTRODUCTIONThe inability to mobilize after surgical intervention for hip fractures in the elderly is established as a risk factor for greater morbidity and mortality. Previous studies have evaluated the association between the timing and distance of ambulation in the postoperative acute care phase with postoperative complications. The purpose of this study was to evaluate the association between ambulatory distance in the acute postoperative setting and ambulatory capacity at 3 months. METHODSPatients aged 65 and older who were ambulatory at baseline and underwent surgical intervention for hip fractures from 2014 to 2019 were retrospectively reviewed. Consistent with previous literature, patients were divided into two groups: those who were able to ambulate 5 feet within 72 hours after surgical fixation (early ambulatory) and those who were not (minimally ambulatory). RESULTSOne hundred seventy patients (84 early ambulatory and 86 minimally ambulatory) were available for analysis. Using a multivariable ordinal logistic regression model, variables found to be statistically significant predictors of ambulatory status at 3 months were the ability to ambulate five feet in 72 hours (P < 0.0001), ambulatory distance at discharge (P = 0.012), and time from presentation to surgery (P = 0.039). Patients who were able to ambulate 5 feet within 72 hours had 9 times the odds of being independent ambulators rather than a lower ambulatory class (cane, walker, and nonambulatory). Pertrochanteric fractures were less likely than femoral neck fractures to independently ambulate at 3 months (17.2% vs. 42.3%; P = 0.0006). DISCUSSIONAmbulating 5 feet within 72 hours after hip fracture surgery is associated with an increased likelihood of independent ambulation at 3 months postoperatively. This simple and clear goal may be used to help enhance postoperative mobility and independence while providing a metric to guide therapy and help counsel patients and families.
