“…A greater incidence leads to a greater sacral slope, and therefore probably increases the local shearing forces that could be one of the predisposing factors of slipping. Sward et al [13] found the same significant relationship between a large sacral slope, a spondylolysis, and the degree of slip in an identical population of spondylolisthesis patients. During et al [7] found a smaller pelvicsacral angle among 33 patients with spondylolysis and spondylolisthesis grade 1.…”

The anatomic pelvic parameter "incidence" -the angle between the line perpendicular to the middle of the sacral plate and the line joining the middle of the sacral plate to the center of the bicoxofemoral axis -has been shown to be strongly correlated with the sacral slope and lumbar lordosis, and ensures the individual an economical standing position. It is important for determining the sagittal curve of the spine. The angle of incidence has also been shown to depend partly on the sagittal anatomy of sacrum, which is established in childhood while learning to stand and walk. The purpose of this study was (1) to define the relationship between the sacrum and the angle of incidence, and (2) to compare these parameters in three populations: young adults, infants before walking, and patients with spondylolisthesis. Forty-four normal young adults, 32 infants not yet walking and 39 patients with spondylolisthesis due to isthmic spondylolysis underwent a sagittal full-spine radiography. A graphic table and the software for bidimensional study of the sacrum developed by J. Hecquet were used to determine various anatomic and positional parameters. Comparison tests of means, and multiple and partial correlation tests were used. A study of

“…Studies on sacral table inclination, specifically in patients showing spondylolysis without slip, are less numerous. Wiltse (1962) and Swä rd et al (1989) reported more steeply inclined sacral tables in those with spondylolysis than in normal controls, but Inoue et al (2002) failed to find a difference. Most writers reporting associations between sacral table angle and spondylolisthesis/spondylolysis viewed the more steeply inclined sacral table as predisposing toward pars interarticularis fracture and to forward slippage of the vertebra.…”

Spondylolysis, spondylolisthesis, and lumbo‐sacral morphology in a medieval English skeletal population

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.

“…In more than 90% of the cases, the location is L5, and in more than 5% L4. Heredity (Friberg 1939, Stewart 1953, Haukipuro et al 1978, Wynne-Davies and Scott 1979, some sports and gymnastics (Wiltse et al 1975, Jackson et a1 1976, Ichikawa et al 1982, Sward et al 1989 can increase the risk for lysis. About 80% of lysis patients demonstrate an olisthesis, mostly a minor one.…”
