573 patients included a randomized trial to compare two methods of surgical fixation for femoral neck fractures in the elderly were also included in this observational study to determine the proportion of patients taking vitamin D supplementation and its effects on physical function and reoperation rate. Patients were categorized into 3 cohorts; non-users (did not take vitamin D supplementation), inconsistent vitamin D supplementation users (1-2 visits), and consistent vitamin D supplementation users (3-4 visits).

Why was this study needed now?
Vitamin D plays a crucial role in bone health. The use of vitamin D supplementation to improve outcome in fracture patients has been of interest in the orthopaedic community, especially in older patients. However, few studies have assessed its use in a large cohort of patients.
What was the principal research question?
Does vitamin D supplementation improve post-injury physical function and reduce the rate of re-operation among femoral neck fracture patients?
Population: 573 patients over the age of 50 undergoing surgery for femoral neck fracture. Patients were randomized to be treated with either cancellous screws or sliding hip screws. In this study, patients were categorized into 3 groups based on their usage of the vitamin D supplement provided in the original study.
Intervention: Consistent Vitamin D supplementation: Patients were categorized as consistent vitamin D users (3-4 visits) over the first 6 months of follow-up
Comparison: Inconsistent Vitamin D supplementation: Patients were categorized as inconsistent vitamin D users (1-2 visits) over the first 6 months of follow-up Non-users: Patients were categorized as non-users (0 visits) over the first 6 months of follow-up
Outcomes: Physical function was assessed using the physical component of the short-form 12 (SF-12) and the rate of reoperation was assessed. Linear regression was used to assess the effect of vitamin D supplementation on these outcomes.
Methods: RCT: Secondary analysis
Time: 12 months
