肾性骨病的骨膜下骨吸收

Subperiosteal Resorption in Renal Osteodystrophy

笔者采用手骨直接Ｘ线放大摄影和双手Ｘ线平片来研究慢性肾衰血透病人５１例。特征性的指骨骨膜下吸收放大摄影发现２５例占４９％；平片为１１例占２１．６％，结果表明，放大摄影的阳性率明显高于平片（Ｐ＜０．００５）。骨膜下吸收的二、三指中间指骨桡侧及指骨末端是肾性骨病的＂靶区＂，认为二者无显著差异（Ｐ＞０．５０）。骨膜下吸收还与血透时间、血磷、血钙和碱性磷酸酶水平相关。

patients with hemodialysis of chronical kidney dysfunction were studied using direct radiographic magnification and conventional radiographic film of the hands.25(49%)of these patients were detected of having the characteristic sign of subperiosteal bone resorption,using t he former technique,while only 11(21.6%)were detected out using the latter. Significance could be seen between the two techniques and that the former is better could be infered(P<0.005). Subperiosteal resoaption occured in the radial aspects of the middle phalanges of the index and middle fingers and occured in terminal tufts,two' target zone' of renal osteodystrophy, is believed to have no statistical differences(P>0.50). Also,subperiosteal resorption is conclueded to be in connection with time on hemedialysis,blood level of phosphate, calcium and AKP.
