已知脑卒中偏瘫患者,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(micro-densitometry MD),测定第二中指骨骨质疏松症的各项指标,分析左右指骨的差别,以便弄清其病态。研究对象为脑卒中后偏瘫(患病时间1485±1907日)患者33例,应用微骨密度计测定骨量及骨盐量,其中10例给予1—α—OH—D_3 6个月观察 Known stroke hemiplegia patients, paralysis prone to fracture of the femoral neck. The purpose of this study was to determine the differences of the phalanges of the left and right phalanges by micro-densitometry (MD) and to determine the pathology of the second phalanx osteoporosis. 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 by micro-densitometer, of which 10 cases were given 1-α-OH-D 3 for 6 months
