title: Bone health and clinical results after hip fracture surgery in patients with subclinical hypothyroidism.
abstract: BACKGROUND
  Subclinical thyroid dysfunction might influence a bone health. We evaluated whether subclinical hypothyroidism adversely affects bone health including bone mineral density (BMD), level of vitamin D, and bone turnover status in patients with hip fracture.
  
  
  METHODS
  We evaluated 471 patients aged 50 years or older, who underwent hip fracture surgeries. BMD, level of vitamin D, bone turnover status, and one-year mortality were compared between subclinical hypothyroidism group and control group.
  
  
  RESULTS
  BMD of femur and the level of 25-hydroxy-vitamin D (25-[OH]D) were similar in the two groups. There were no significant differences in bone turnover markers according to thyroid function. No significant differences were observed between the groups in utilization of intensive care unit (ICU), length of hospital stay, mobility, and one-year mortality.
  
  
  CONCLUSIONS
  Subclinical hypothyroidism was not associated with reduced bone health, including BMD, the level of 25-(OH)D, and bone turnover marker.
