A Case Report: Femoral Fracture in a Multiple Sclerosis Patient with Vitamin D Deficiency−A Preventable Injury

Abstract

In this report, we describe the management of a multiple sclerosis patient with a femoral fracture who had severe vitamin D deficiency. After the patient's preoperative laboratory studies revealed a normal platelet count, the orthopedic surgeon performed an intramedullary rod fixation on the patient's left femoral fracture. After the surgery, the diagnosis of vitamin D deficiency was made by measuring the circulating serum concentration of 25-dihydroxyvita-min D (25(OH)D) via Disorin's Vitamin D immunochemiluminometric assay LIASION by LabCorp (Laboratory Corporation of America). The patient's postoperative management included the oral administration of 4000 IU of vitamin D3 in a gel-cap suspension that resulted in an elevation of the blood serum concentration of 25(OH)D to an optimal concentration of >80 nmol/L (32 ng/ml).
