Dynamic measurements of intraosseous pressures in lumbar vertebrae were performed to determine the effects of positional change on lumbar vertebral circulation. The data collected are applicable to the question of spinal canal stenosis. The measurements were made in 23 patients, 12 of whom had spinal canal stenosis and 11 of whom had spondylosis deformans. The pressures within the spinous processes of L3 and L5 were measured continuously while the patients were prone, lying in the lateral position, and standing. The pressures ranged from approximately 10 to 30 mm Hg in the prone position and showed substantial changes with changes in position. In each subject, they were lowest in the prone, intermediate in the lateral, and highest in the standing position.
对腰椎骨内压力进行动态测量，以确定体位变化对腰椎椎体循环的影响。所收集的数据适用于椎管狭窄问题。对23名患者进行了测量，其中12人患有椎管狭窄，11人患有脊柱畸形。在患者俯卧、侧卧和站立时，连续测量L3和L5棘突内的压力。俯卧位时压力范围约为10至30毫米汞柱，且随体位变化有显著变化。在每个受试者中，俯卧位时压力最低，侧卧位时居中，站立位时最高。
