title: Outcomes of elderly patients with nondisplaced femoral neck fractures.
abstract: Seventy patients with nondisplaced femoral neck fractures treated by cannulated screw fixation were followed up prospectively for 6 months. Preinjury Functional Independence Measure scores and comorbidities were recorded as were operative time, type of anesthesia, estimated blood loss, transfusions, and postoperative complications. Functional Independence Measure scores were reassessed at 3 and 6 months. The mean age of the patients was 78 years. The 6-month mortality was 5.7%. The mean overall Functional Independence Measure scores at 3 and 6 months were 86% and 89% of the initial score respectively. Locomotion Functional Independence Measure scores at 3 and 6 months were 73% and 89% of the initial score, respectively. Multiple regression analysis found patient age and initial overall Functional Independence Measure score to be independent predictors of overall, locomotion, and transfer Functional Independence Measure scores at 3 months. At 6 months, only initial Functional Independence Measure score predicted ultimate Functional Independence Measure scores. This suggests that patient age may affect the speed of recovery but not the ultimate functional result. Of comorbidities, only chronic obstructive pulmonary disease significantly affected functional recovery at 3 months, but not at 6 months. Operative time, estimated blood loss, type of anesthesia, and patient gender did not affect functional outcomes. Patients who sustain a nondisplaced femoral neck fracture experience predictable and lasting loss of function. Low initial functional status predicts a poorer outcome. Age and pulmonary comorbidity affect speed of recovery.
