Abstract

Introduction: Hypovitaminosis D is common in patients undergoing orthopaedic trauma surgery. While previous studies have shown that vitamin D levels correlate with functional outcome after hip fracture surgery, the significance of vitamin D levels on outcomes after surgery in other orthopaedic trauma patients is unknown. The purpose of this study was to determine if vitamin D levels correlated with outcomes in ankle fracture patients. Materials and methods: We reviewed a prospective registry of patients who underwent operative treatment for ankle fractures from 2003 to 2012. Preoperative serum 25-hydroxyvitamin D (25[OH]D) levels were measured, and the primary and secondary outcomes included foot and ankle outcome scores (FAOS) and ankle range of motion. Data were also collected on patient comorbidities, articular malreductions, and wound complications. Included patients had at least 12 months of clinical outcome data. Results: Ninety-eight patients operatively treated for ankle fractures met our inclusion criteria. Of these 98 patients, 36 (37 %) were deficient in vitamin D (<20 ng/ml) and 31 (32 %) had vitamin D insufficiency (<30 ng/ml, ≥20 mg/ml). Patients with vitamin D deficiency were similar with regard to age, gender, and comorbidities compared to patients with vitamin D levels ≥20. Univariate analysis revealed that patients with vitamin D deficiency had significantly worse FAOS with regard to symptoms (P = 0.017) and quality of life (P = 0.040) domains than patients with vitamin D levels ≥20. Multivariate regression analysis suggested that vitamin D deficiency was a factor in inferior FAOS with regard to symptoms, activities of daily living, and quality of life. Conclusions: In our group of patients with operative treated ankle fractures, preoperative vitamin D deficiency correlated with inferior clinical outcomes at a minimum of 1 year follow-up. Our study suggests that deficient vitamin D levels may result in worse outcomes in orthopaedic trauma patients recovering from fracture fixation.
