This paper records measurement of the lumbar spinal canal by diagnostic ultrasound in more than 700 subjects from early infancy until the age of 65 years. It demonstrates the range of canal size in a South Yorkshire population. The canal is relatively wide in children, reaches a maximum diameter in the late teens, and reduces slightly by late adult life. This does not appear to be related to occupation. Comparisons are made with more than 700 patients with symptoms of back pain, especially patients with disabling disc symptoms, root entrapment syndrome, and neurogenic claudication. The size of the central canal is particularly significant in patients who have neurogenic claudication and disc symptoms. It is less significant in root entrapment syndrome.
本文记录了700多名从婴儿早期到65岁的受试者通过诊断性超声对腰椎管进行的测量。它展示了南约克郡人群椎管大小的范围。儿童的椎管相对较宽，在青少年后期达到最大直径，到成年后期略有缩小。这似乎与职业无关。将其与700多名有背痛症状的患者进行了比较，特别是有严重椎间盘症状、神经根卡压综合征和神经源性跛行的患者。中央椎管的大小在患有神经源性跛行和椎间盘症状的患者中尤为重要。在神经根卡压综合征中则不太重要。
