Tibial ultrasound velocity in women with wrist fracture.
The aim of the study was to determine whether cortical midtibial speed of sound (Soundscan 2000, Myriad Ultrasound Systems, Israel) was able to discriminate women who sustained a fracture of the distal radius from normal women and to compare the performance of tibial speed of sound with dual-energy X-ray absorptiometry (DXA) of the distal radius, hip, and lumbar spine. The study population consisted of 40 women with a wrist fracture and 41 healthy age-matched controls. Tibial ultrasound velocity correlated with bone mineral density of the distal forearm (rS = 0.64, p < 0.001), the hip (rS = 0.46, p < 0.001), and the lumbar spine (rS = 0.51, p < 0.001). The mean speed of sound value at the mid-tibia of the wrist fracture patients (3873 m/s) was lower than that of the controls (3913 m/s), but the difference was not statistically significant (p = 0.12). All DXA values were significantly lower in fracture cases. Receiver operating curve analysis showed that mid-tibial ultrasound velocity was less effective than DXA of the distal forearm to discriminate wrist fracture patients from age-matched controls.
