The internal pressure of simple bone cysts was found to be slightly higher than the normal pressure of the bone marrow in the contralateral limb. The pressure within the cyst was measured during drilling with a Kirschner wire; it gradually decreased as the number of drill-holes increased. The PO2 of the cyst fluid was markedly lower than that of either venous or arterial blood measured synchronously. It is suggested that venous obstruction in the bone is the likely cause of these cysts. Seven patients with simple bone cysts were treated by the multiple drill-hole method, and the clinical outcome was excellent. Multiple drilling may prove to be the treatment of choice for simple bone cysts in the younger patient, as it presents fewer hazards than other procedures.
研究发现，单纯性骨囊肿的内部压力略高于对侧肢体骨髓的正常压力。在用克氏针钻孔时测量囊肿内的压力；随着钻孔数量的增加，压力逐渐降低。囊肿液的氧分压明显低于同步测量的静脉血或动脉血的氧分压。提示骨内静脉阻塞可能是这些囊肿的病因。7例单纯性骨囊肿患者采用多钻孔法治疗，临床效果良好。对于年轻患者的单纯性骨囊肿，多钻孔可能是首选的治疗方法，因为它比其他方法风险更小。
