Intraosseous pressure was measured under standardized and different functional conditions in 11 necrotic lunates in different stages of the disease and in 11 viable lunates. Both the viable and the necrotic lunates show a significant increase of the pressure, if the wrist is brought into dorsiflexion. Both groups do not differ significantly, but the mean value of the necrotic group exceeds that of the viable group clearly. There might have some technical problems in measuring. Venous stasis by tourniquet provoked increase of pressure, too. The increase of pressure both in dorsiflexion and in venous stasis is evidence of venous drainage. Dorsiflexion impairs the venous drainage of the lunate, which promotes necrosis. The increase of intraosseous pressure in necrotic lunates can be understood as a failure of the physiologic regulation of the intraosseous pressure by moving the wrist and cause of necrotic changes.
在标准化和不同功能条件下，对处于疾病不同阶段的11个坏死月骨和11个存活月骨测量了骨内压。如果将手腕背屈，存活月骨和坏死月骨的压力均显著升高。两组之间无显著差异，但坏死组的平均值明显超过存活组。测量过程中可能存在一些技术问题。止血带引起的静脉淤滞也会导致压力升高。背屈和静脉淤滞时压力升高均表明存在静脉引流。背屈会损害月骨的静脉引流，从而促进坏死。坏死月骨内骨内压升高可理解为通过活动手腕对骨内压进行生理调节失败以及坏死改变的原因。
