The aim of this study was to compare pedicle dimensions in degenerative lumbar spinal stenosis (DLSS) with those in the general population. A retrospective computerized tomography (CT) study for lumbar vertebrae (L1 to L5) from two sample populations was used. The first included 165 participants with symptomatic DLSS (age range: 40-88 years, sex ratio: 80 M/85 F), and the second had 180 individuals from the general population (age range: 40-99 years, sex ratio: 90 M/90 F). Both males and females in the stenosis group manifested significantly greater pedicle width than the control group at all lumbar levels ( < 0.05). In addition, pedicle heights for stenosis females were remarkably smaller on L4 and L5 levels compared to their counterparts in the control group ( < 0.001). Males have larger pedicles than females for all lumbar levels ( < 0.001). Age and BMI did not demonstrate significant association with pedicle dimensions. Our outcomes indicate that individuals with DLSS have larger pedicle widths than the control group. More so, pedicle dimensions are gender-dependent but independent of age and BMI.
本研究旨在比较退行性腰椎管狭窄症（DLSS）患者与普通人群的椎弓根尺寸。使用了来自两个样本群体的回顾性计算机断层扫描（CT）腰椎（L1 至 L5）研究。第一组包括 165 名有症状的 DLSS 患者（年龄范围：40-88 岁，性别比例：80M/85F），第二组包括 180 名普通人群（年龄范围：40-99 岁，性别比例：90M/90F）。狭窄组的男性和女性在所有腰椎水平的椎弓根宽度均明显大于对照组（<0.05）。此外，与对照组相比，狭窄症女性在 L4 和 L5 水平的椎弓根高度明显更小（<0.001）。男性在所有腰椎水平的椎弓根均大于女性（<0.001）。年龄和 BMI 与椎弓根尺寸没有显著相关性。我们的研究结果表明，DLSS 患者的椎弓根宽度大于对照组。此外，椎弓根尺寸与性别有关，但与年龄和 BMI 无关。
