Cross-sectional study.
To report the prevalence and relationship of developmental cervical and lumbar spinal stenosis (DCSS and DLSS) with the bone parameters of the skull and extremities.
DCSS and DLSS are found occasionally in daily practice. DCSS and DLSS can cause compressive myelopathy, radiculopathy, and cauda equina syndrome; however, data on their prevalence and correlation with skull and skeletal extremity profiles is scarce.
A cross-sectional measurement study of 293 whole-body dried-bone samples was conducted. We measured the anteroposterior (AP) and transverse diameter of the fourth to sixth cervical vertebrae (C4-C6) and third to fifth lumbar vertebrae (L3-L5). Stenosis of the cervical spine and lumbar spine was defined as an AP diameter of <12 mm and <13 mm, respectively. We also measured the skull circumference, the AP and transverse diameters of the foramen magnum, the inner and outer inter distances between the left and right orbital bones, the humerus length, and the femoral length. Kruskal-Wallis and post hoc analyses were used in the statistical analyses.
The age was 22-93 years. DCSS was found in 59 (20.1%) and DLSS in 28 (9.6%). Twelve samples had both DCSS and DLSS (development spinal stenosis, DSS). When compared to the "no spinal stenosis sample," DSS (-), DCSS and DSS had a significantly smaller skull circumference, the transverse diameter of the foramen magnum, and inner and outer distance between the orbital bone (p<0.05). There was no significant difference in humeral length, femoral length, or AP diameter of the foramen magnum.
DCSS was correlated with a small skull, a small transverse diameter of the foramen magnum, and a small orbital bone. A small skull was strongly associated with a small cervical canal. DLSS, on the other hand, was unrelated to either a small cervical canal or a small skull.
横断面研究。
报告发育性颈椎管狭窄症（DCSS）和发育性腰椎管狭窄症（DLSS）的患病率及其与颅骨和四肢骨骼参数的关系。
DCSS和DLSS在日常实践中偶尔会被发现。DCSS和DLSS可导致压迫性脊髓病、神经根病和马尾综合征；然而，关于它们的患病率以及与颅骨和骨骼四肢轮廓相关性的数据却很少。
对293个全身干燥骨样本进行横断面测量研究。我们测量了第四至第六颈椎（C4 - C6）和第三至第五腰椎（L3 - L5）的前后径（AP）和横径。颈椎管狭窄和腰椎管狭窄分别定义为AP直径<12毫米和<13毫米。我们还测量了头围、枕大孔的AP和横径、左右眶骨之间的内外间距、肱骨长度和股骨长度。统计分析采用Kruskal - Wallis检验和事后分析。
年龄在22 - 93岁之间。发现59例（20.1%）患有DCSS，28例（9.6%）患有DLSS。12个样本同时患有DCSS和DLSS（发育性椎管狭窄，DSS）。与“无椎管狭窄样本”DSS（-）相比，DCSS和DSS的头围、枕大孔横径以及眶骨之间的内外间距明显更小（p<0.05）。肱骨长度、股骨长度或枕大孔的AP直径没有显著差异。
DCSS与小头、小枕大孔横径和小眶骨相关。小头与小颈椎管密切相关。另一方面，DLSS与小颈椎管或小头均无关。
