Official Title: A Pilot Study of Role of Vitamin D in Regulation of Bone Homeostasis in Orthopaedic Polytrauma Patients
Brief Summary: Although vitamin D is known to play a major role in multiple organ functions in healthy adults, including bone homeostasis, its role in the unique population of orthopaedic polytrauma patients has not been well described. The aim of this therapeutic randomized placebo-controlled feasibility study is to determine the effect of vitamin D supplementation initiated on admission on patients' 25(OH)-D level, bone turnover markers, and clinical outcomes in a cohort of adult orthopaedic polytrauma patients. Polytrauma patients with one or more orthopaedic injuries admitted to an urban Level I trauma center will be screened for eligibility based upon strict inclusion and exclusion criteria. Sixty patients meeting the criteria will be consented, enrolled and randomized in a 1:1 ratio to intervention and control (placebo) arm. Baseline 25(OH)-D and bone turnover marker levels will be drawn for all the patients on admission, and the intervention arm will receive a one-time dose of ergocalciferol (Vitamin D2) 400,000 IU shortly after enrollment. The labs will be repeated 7 days after the initial draw or at discharge, whichever occurs first. Patients' daily immobilization status, baseline characteristics and clinical outcomes will be recorded. Statistical methods will be used to assess whether there is a difference in 25(OH)-D and bone turnover markers levels associated with the intervention.
