“…In addition, L5/S1 segmental lumbar spine is very different from upper lumbar spine, the processus transversus of L5/S1 is very narrow, only 13.4 mm ± 4.1 mm, while the processus transversus of other lumbars is about 24 mm ± 3 mm [8]. In addition, there is a block of horizontal lateral iliac on the L5/S1 intervertebral disc [9].…”

“…Meanwhile, according to the anatomy study, the distance between S1 vertebral plate edge and the S1 vertebral endplate is relatively constant, with an average of about 13.9 mm. But on the other hand, the distance between the edge of L5 vertebral plate and L5 vertebral endplate varies from 3.0 mm to 8.5 mm [8]. Compared with the upper lumbar vertebral plate gap, L5/S1 vertebral plate gap is very big, with an average of 31 mm (21-40 mm).…”

“…In transitional lumbosacral segmentation, it was observed that the lumbosacral intervertebral disc is significantly narrowed. [17][18][19] The incidence of disc herniation is found to be higher and can occur even at young ages.

Background: Sacralization of L5 is a congenital anomaly, in which the lumbar vertebra, mainly its transverse process, gets fused or semi-fused with the sacrum or the ilium or to both. This fusion can occur in one or both sides of the body. Sacralization leads to fusion of the L5 (fifth lumbar vertebra) and S1 (first sacral vertebra) and the inter-vertebral disc between them may be narrow. Sacralization of lumbar vertebra may be asymptomatic but is not always clinically insignificant. While sacralization may not affect at all, it can cause problems in some cases. Sacralization may be at times associated with problems in biomechanics and affect the ways of movement and posture control. Sacralization may also be an important consideration in disc surgeries. This study has been carried out to find out prevalence of sacralisation of transverse process of fifth lumbar vertebrae.Methods: The present study of transverse sacralisation of fifth lumbar vertebra was carried out on 35 randomly selected patients. The sample consisted of patients undergoing CT scan for abdominal complains. Bone window of all patients were evaluated to look for lumbosacral transitional vertebra.Results: The prevalence of transverse sacralization of lumbar vertebra turned out to be 25.7% out of which Castellvi type IIb was found to be most common, accounting for 33.3% cases. 5.7% comprised the group of normal variant (Castellvi’s type I) and 68.6% were normal. Conclusions: It is important to determine lumbosacral transitional vertebra as it can affect spinal movement and put excess stress on the lumbar vertebrae and in between disc. Moreover it can have a bearing on counting of vertebral levels specially during planning of spinal surgey.

“…The incidence ratio of sacralization to lumbarization was reported as 2:1 (Eyo et al). In transitional lumbosacral segmentation, it was observed that the lumbosacral intervertebral disc is significantly narrowed (Tini et al, 1977;Ebraheim et al, 1997;Revuelta et al, 2000), the incidence of disc herniation is found to be higher and can occur even at young ages (Williams, 1965;Otani et al, 2001). There was also relationship established between transitional vertebrae and the degree of slippage in spondylolytic spondylolisthesis (Kim & Suk;Cinotti et al, 1997).…”

SUMMARY:A lumbosacral transitional vertebra is a rare congenital anomaly which occurs because of defect in the segmentation of the lumbosacral spine during development. During routine osteology classes for the medical students at the Kasturba Medical College, Mangalore, India, one of the sacra showed the fusion of the fifth lumbar vertebra with the sacrum. The specimen showed an incomplete fusion (sacralization) on the left side and the transverse process was of the large butterfly shape, while on the right it was about the usual size. Though this variation is well known, the details of this anomaly are rarely reported in the anatomical literature. Since there is a strong relationship between the lumbosacral transitional vertebrae and low back pain, this anomaly has gotten increased clinical interest. So this case was studied in detail with relevant review of literature and its surgical, radiological implications are discussed.
