The prevalence of spondylolysis and spondylolisthesis was studied in an adult skeletal series from a rural English medieval archaeological site. Attempts were made to evaluate the association of three aspects of lumbo-sacral skeletal morphology (pelvic incidence (a measure of the anterior inclination of the sacral table), lumbar transverse process width, and the presence of lumbo-sacral spina bifida occulta) with spondylolysis and spondylolisthesis. Results indicated a high prevalence of spondylolysis compared with a modern reference population, but few cases of spondylolisthesis were identified. Analysis of prevalence with respect to age suggests that in the study population, pars interarticularis defects generally formed late in the growth period or early in adult life. The study group showed a high mean pelvic incidence compared with modern Western Europeans, indicating a more steeply inclined sacral table, which may have elevated the risk of developing pars interarticularis defects. However, no statistically valid association could be demonstrated between the presence/absence of spondylolysis and pelvic incidence in the study material. There was no evidence for a link between lumbar transverse process index or lumbo-sacral spina bifida occulta and spondylolysis/spondylolisthesis. It is concluded that the potential role of lumbo-sacral morphology, as well as of activity regimes, should be considered when interpreting spondylolysis in paleopathological studies. If the frequency of spondylolysis is to some extent an indicator of past activity regimes, it may reflect lifestyle in younger individuals rather than in mature adults. Further work investigating the link between spondylolysis and lumbo-sacral morphological variables in premodern populations would be of value.
对一个来自英国乡村中世纪考古遗址的成人骨骼样本进行了椎弓峡部裂和腰椎滑脱患病率的研究。尝试评估腰骶部骨骼形态的三个方面（骨盆入射角（骶骨平台前倾的一种测量方法）、腰椎横突宽度以及腰骶部隐性脊柱裂的存在情况）与椎弓峡部裂和腰椎滑脱之间的关联。结果表明，与现代参照人群相比，椎弓峡部裂的患病率较高，但仅发现少数腰椎滑脱病例。对患病率按年龄进行分析表明，在研究人群中，关节突间部缺损通常在生长后期或成年早期形成。与现代西欧人相比，研究组的平均骨盆入射角较高，表明骶骨平台倾斜度更大，这可能增加了关节突间部缺损的发生风险。然而，在研究材料中，未发现椎弓峡部裂的有无与骨盆入射角之间存在统计学上有效的关联。没有证据表明腰椎横突指数或腰骶部隐性脊柱裂与椎弓峡部裂/腰椎滑脱之间存在联系。得出的结论是，在古病理学研究中解释椎弓峡部裂时，应考虑腰骶部形态以及活动方式的潜在作用。如果椎弓峡部裂的发生率在某种程度上是过去活动方式的一个指标，那么它可能反映的是年轻人而非成年人的生活方式。进一步研究史前人群中椎弓峡部裂与腰骶部形态变量之间的联系将很有价值。
