脑卒中偏瘫患者的瘫痪侧股骨颈易发生骨折。本研究的目的是应用微骨密度计测定法(MD)测定第二指骨骨质疏松症的各项指标,分析左右指骨的差别。研究对象为脑卒中后偏瘫(患病时间1485±1907天)患者33例,应用微骨密度计测量骨量及骨盐量,其中10例给予1-α-OH-D_3 6个月观察其效果。 Stroke patients with paralyzed hemiplegia prone to fracture of the femoral neck. The purpose of this study is to determine the indexes of the second phalanx osteoporosis using the micro-densitometry (MD) and to analyze the difference between the left and right phalanges. The subjects were 33 patients with post-stroke hemiplegia (disease duration 1485 ± 1907 days). The bone mass and the amount of bone salt were measured with a micro-densitometer. The effect of 1-α-OH-D_3 was observed in 10 of 10 patients .
