“…In both case reports, the occurrence of the defect was associated with the intense physical activity of the patient-one was a physical education student, and the remaining ones were heavily involved in sports, heavy labour or underwent a traumatic event. There are also infrequent reports on spondylolysis present in different regions of the spine-cervical and thoracic (Mays, 2007;Larsen, 2015, p. 119).…”

An unusual burial was discovered at the site of Castillo de Huarmey, Peru. The individual buried in the area of pre-Columbian huaca was likely of Chinese origin and came to Peru as a part of a large immigration wave between 1849 and 1874. Over 100 000 Chinese workers were brought to Peru during that timeframe, to replace freed slaves in many branches of the Peruvian economy. The individual's skeleton showed multiple-level bilateral spondylolysis in the lumbar vertebrae. This kind of bony defect is very rare and often related to intensive and strenuous physical activity. The analysis allows for an insight into historical lifestyles and immigrant experiences as registered in skeletal remains.

“…Spondylolytic defects of the lumbar vertebrae are unique to humans and they are associated with a similarly unique human anatomical feature, lordosis of the lower lumbar spine (Ward and Latimer, 2005). These defects are most prevalent at the lowest lumbar segment, and although they sometimes occur at higher levels, these higher level defects appear to have a different morphology and probable etiology (Mays, 2006a). Defects of the pars interarticularis can lead to spondylolisthesis, or slipping of the vertebral body anteriorly due to the inclination of the lowest lumbar vertebrae in lordotic posture (e.g.…”

The British medieval population from Wharram Percy, England, has a greater prevalence of isthmic spondylolysis (11.9% of skeletons, 8.5% at the L5 level) than in modern populations (3%-6%). This may in part be due to differences in activity patterns between groups. However, Ward and Latimer (Spine 30 [2005] 1808-1814) proposed that the likelihood of developing and maintaining spondylolytic defects is also influenced by a lack of sufficient increase in mediolateral separation between articular processes in the lowest lumbar segments, given the human lumbar lordosis. Here, we demonstrate that spondylolytic individuals from Wharram Percy tend to have a less pronounced difference between mediolateral facet joint spacing of adjacent segments in the lowest lumbar region than do unaffected individuals, as seen in modern clinical and skeletal populations. These comparisons suggest that regardless of lifestyle, insufficient mediolateral increase in facet spacing predisposes people to spondylolytic defects, and so interfacet spacing patterns may have predictive utility in a clinical context. We also compare the Wharram Percy sample to a modern sample from the Hamann Todd collection with a typically modern prevalence rate. Data do not support the hypothesis that the Wharram Percy individuals had a less pronounced interfacet increase than the Hamann Todd, although they do have narrower lumbar facet spacing at the lowest three levels. Further investigation of anatomical variation underlying population-specific prevalence rates needs to be conducted.

The occurrence of spondylolysis (neural arch separation at the pars interarticularis) is reported in a pre‐contact (720–550 Cal BP) Central California population, CA‐CCo‐647 (n = 46). Spondylolysis was examined within this population to assess differences in sex, age, and possible relationships with biological affinity. Furthermore, prevalence rates of spondylolysis were compared across various populations to discern the aetiology of the defect. Within CA‐CCo‐647, spondylolysis was found in 17.4% (8/46) of the population. All occurrences are complete, bilateral separations of the neural arch in the lower lumbar (L4 and L5). The defect is not seen in individuals below the age of 18, and there is no correlation between adult age and spondylolysis. Male individuals display the defect at a higher rate (30.8% ‐ 4/13) than female individuals (12.1% ‐ 4/33); however, this is not a statistically significant finding. There does seem to be a correlation between an individual's sex and the onset of the defect; male individuals display spondylolysis at a younger age than female individuals. This finding could represent differences in activity patterns among young male and female individuals. In a biological distance analysis using craniometric data, male and female individuals with spondylolysis clustered closely, suggesting a genetic component for the defect. Finally, significant differences were found in spondylolysis prevalence between various populations representing distinct geographic and temporal settings. Significant differences were found among Native pre‐contact samples and even between two comparable pre‐contact California skeletal samples. These populations all engaged in distinct activities and were likely composed of genetically distinct groups of individuals, which may account for the differences in spondylolysis prevalence. All of these findings, both within CA‐CCo‐647 and between the various samples, suggest that the aetiology of spondylolysis is likely an interaction of genes and activity.
