Shorter unipedal standing time and lower bone mineral density in women with distal radius fractures
Osteoporosis International, 06/30/09

Sakai A et al. – Study demonstrates that unipedal standing time was shorter and bone mineral density (BMD) was lower in women ≥50 years of age with distal radius fractures than those in age-matched women without fractures.

• Aim was to compare unipedal standing time and BMD of women ≥50 yrs of age with distal radius fractures vs age-matched women w/o fractures
  • Fracture group: 54 Japanese women with low-energy distal radius fractures resulting from fall
  • Non-fracture group: 52 community-dwelling Japanese women w/o fractures
• Unipedal standing time and BMD were measured

• No differences in age and BMI between the 2 groups
• Percentage of women with unipedal standing time <15 s was 44.4% in the fracture group and 13.5% in the non-fracture group
• Respective frequencies for >120 s were 20.4% and 50.0%
• T-score of BMD was lower in the fracture than non-fracture group
• Logistic regression analysis identified unipedal standing time <15 s and T-score <70% as significant factors associated with distal radius fractures
• T-score <70% was significant in subjects <65 yrs
• Unipedal standing time <15 s was significant in those ≥65 yrs
