骨折与无骨折史患者的定量超声检查比较

Quantitative Ultrasound Diagnosis of Osteoporotic Patients With Fracture History

目的用定量超声方法对有骨折史的骨质疏松症患者进行骨量检查。 方法用CUBAClinical型定量骨密度超声仪对 3 93例被疑为骨质疏松的患者进行检测 ,并根据病史按有无骨折史进行分组。分析二组患者宽频超声衰减 (BUA)、超声速率 (VOS)、强度指数 (SI)与骨折次数的关系。 结果伴有骨折史的骨质疏松症患者的BUA、VOS、SI值都要比无骨折史的患者明显降低 (P =0 .0 0 0 )。 结论定量超声值与骨折的发生次数呈负相关 ,其测定值越低 ,骨折的发生次数越多 ;骨的质量下降是造成骨质疏松骨折的主要原因。

Objective To investigate the bone mineral density of osteoporotic patients with a fracture history. 393 patients of unconfirmed osteoporosis were classified into 2 groups: fracture and non fracture, and were examined with quantitative ultrasonic densitometry. The correlation of VOS?BUA?SI?and fracture incidence was analysed. The correlation coefficients between BUA, VOS, SI, and fracture incidence were-0.262,-0.2269,-0.2611,respectively. The parameters of VOS, BUA, and SI of patients with fracture were significant lower than those of patients without fracture (P=0.000). The parameters of quantitative ultrasonic densitometry were negatively correlated to the fracture incidence being, the lower the densitometric value, the higher the fracture rate. So, the decline of bone quality is the main cause of fracture in osteoporosis patients.
