Intraosseous pressure was measured in the lunate of 10 patients undergoing surgery for Kienböck's disease. Using the styloid process of the radius and the capitate as reference points of bone pressure, I found a stasis rather than arterial insufficiency in the lunate. This pattern was observed regardless of the stage of the disease according to Ståhl and regardless of the finding by technetium TC 99m-methylene diphosphonate scintigraphy. The significance of this finding is still unknown but questions the current concept that Kienböck's disease is caused by arterial insufficiency, because these results imply an interruption of the blood flow as a result of venous congestion.
对10例因月骨无菌性坏死而接受手术的患者的月骨进行了骨内压测量。以桡骨茎突和头状骨作为骨压的参考点，我发现月骨内存在血流淤滞而非动脉供血不足。无论根据施塔尔分类法该疾病处于何种阶段，也无论锝Tc 99m-亚甲基二膦酸盐闪烁扫描的结果如何，均观察到了这种模式。这一发现的意义尚不清楚，但对目前认为月骨无菌性坏死由动脉供血不足引起的观念提出了质疑，因为这些结果暗示血流中断是静脉充血所致。
