- Abstract
Objective To evaluate if the difference exists between the different types of osteoporotic vertebral fractures and the vertebral volumetric bone mineral density (BMD) detected using quantitative computed tomography (QCT). Methods The QCT BMD was obtained from a cohort of 77 postmenopausal female patients with lumbar fracture (aging from 55 to 85 years, mean age 71 ± 7. 84 years). All the fractures were fragile ones. Patients with only one lumbar vertebral body fracture were involved. BMD of the non-fractured vertebrae was measured and calculated using QCT. The fractures were divided to wedge, biconcave, and crush type according to the saggital CT image. Independent-samples t test was used to evaluate the difference of BMD and age between wedge and biconcave type of fractures. Results The difference in age between wedge (mean age 70. 26 ± 7. 99 years) and biconcave (mean age 70. 92 ± 7. 80 years) fracture was not statistically significant (t = -0. 347, P =0.730), therefore excluding the interference of age factor. There was statistically significant difference between wedge and biconcave fractures (t = 2. 254, P = 0. 028). BMD in group of biconcave fracture (mean 32. 08 mg/cm³) was lower than that of wedge fracture (mean 45. 05 mg/cm). Conclusion There may be correlation between type of osteoporotic lumbar fractures and BMD. BMD in biconcave fractures may be higher than that in wedge fractures.
