Differences in Function and Fracture Risk in Postmenopausal Women With and Without a Recent Distal Radius Fracture.

Abstract

A distal radius fracture (DRF) is commonly the first fracture to occur in early postmenopausal women. The reasons for sustaining a DRF may be related to fall risk, bone fragility, or both. The objective of this study was to compare functional and fracture risk status in postmenopausal women with and without a recent DRF and explore the relationships between function, grip strength, and fracture risk status. Seventy-seven women a ges 50-78 with (n = 32) and without (n = 45) a history of DRF in the past 2 years participated. Balance, timed up and go (TUG), gait velocity, balance confidence, sit to stand, grip strength, and fracture risk were assessed. There was a significant group difference after controlling for physical activity level (Pillai's Trace, p < .05) where women with DRF had poorer outcomes on sit to stand, gait velocity, TUG, and fracture risk status. Grip strength was associated with functional tests, particularly in women with DRF. Women with a recent DRF demonstrated lower functional status and higher fracture risk compared to women without. Grip strength was associated with measures of function and fracture risk, and may complement screening tools for this population.
