Abstract

A 56-year-old man was referred with left-sided hip pain. MRI scans demonstrated an undisplaced stress fracture in the femoral neck and subchondral oedema within the femoral head. Bone densitometry showed T-scores of −2.0 at the spine, −3.5 at the femoral neck and −2.4 for the total hip. Laboratory tests revealed 25-hydroxyvitamin D <10 nmol/L. He was prescribed a 10-day course of calciferol 1.25 mg (50 000 IU)/day and started on calcium carbonate 1.25 g twice daily. Following the correction of vitamin D deficiency, his symptoms resolved. A striking feature of this patient was the complete reversal of ‘osteoporosis’ within 14 months with vitamin D and calcium supplementation. Bone mineral densities (BMDs) increased by 19.5% and 33.4% at the spine and hip, respectively. Such changes are never seen with conventional pharmacological management of osteoporosis. Vitamin D deficiency should be considered as a cause for reduced BMD in people with risk factors.
