“…For a detailed description of the vertebral body and intervertebral disc geometry evaluation, as well as rationalization of this measurements, please see Vialle et al [5], Been et al [18], De Carvalho [19] and Kimura et al [20]. For each of the five lumbar vertebrae, two lines were drawn: along the superior endplate of the vertebral body (also on the first sacral vertebra) and along the inferior endplate of the vertebral body (Fig.…”

“…The sagittal balance is characterized by both pelvic and spinal parameters. Patients with spondylolysis and spondylolisthesis demonstrated a significantly greater pelvic incidence than the normal population [3]; sacral tilt is high in patients with spondylolysis and low grades of isthmic spondylolisthesis (grade 1 or 2 according to the Meyerding [4] classification) and low in severe isthmic spondylolisthesis (grade 3 or 4 according to the Meyerding [4] classification) [5]. Lumbar spines with spondylolysis and spondylolisthesis usually demonstrate high lumbar lordosis, high lumbosacral angle and high inclination of superior and inferior endplate of the last lumbar vertebra (L5) in relation to the horizon [6,7].…”

The objective is to evaluate the geometric parameters of vertebral bodies and intervertebral discs in spinal segments adjacent to spondylolysis and spondylolisthesis. This pilot cross-sectional study was an ancillary project to the Framingham Heart Study. The presence of spondylolysis and spondylolisthesis as well as measurements of spinal geometry were identified on CT imaging of 188 individuals. Spinal geometry measurements included lordosis angle, wedging of each lumbar vertebra and intervertebral disc. Last measurements were used to calculate RB, the sum of the lumbar L1-L5 body wedge angles; and RD, the sum of the lumbar L1-L5 intervertebral disc angles. Using Wilcoxon-Mann-Whitney test we compared the geometric parameters between individuals with no pathology and ones with spondylolysis (with no listhesis) at L5 vertebra, ones with isthmic spondylolisthesis at L5-S1 level, and ones with degenerative spondylolisthesis at L5-S1 level. Spinal geometry in individuals with spondylolysis or listhesis at L5 shows three major patterns: In spondylolysis without listhesis, spinal morphology is similar to that of healthy individuals; In isthmic spondylolisthesis there is high lordosis angle, high L5 vertebral body wedging and very high L4-5 disc wedging; In degenerative spondylolisthesis, spinal morphology shows more lordotic wedging of the L5 vertebral body, and less lordotic wedging of intervertebral discs. In conclusion, there are unique geometrical features of the vertebrae and discs in spondylolysis or listhesis. These findings need to be reproduced in larger scale study.

“…In this manner, 17 segments (Th1/2 to L5/S1) were evaluated; inclination of the spine, and the hip/sacral angle were calculated. In accordance with Vialle et al, we measured thoracic kyphosis angle (TK) and lumbar lordosis angle (LL) based on the graphic demonstration of the SpinalMouse [13]. TK was reported as the angle between the cranial end plate of T4 and the caudal end [21].…”

“…The sagittal alignment of the spine is thought to be one of the most important factors that influence disorders around the neck and shoulder [8]- [12]. The reciprocal curvature of the spine in sagittal alignment allows for efficient absorption of the loads applied to the spinal column and increases the efficiency of the spinal musculature [13]. A slouched posture significantly reduces scapular upward rotation in arm elevation [10] [12] [14] [15].…”

Background: The relationship between chronic neck and shoulder pain and posture remains controversial. The purpose of this study was to investigate the relationship between chronic neck and shoulder pain and spinal sagittal alignment in standing posture in younger generation. Methods: Subjects included 57 females and 32 males (average age, 29.9 ± 5.7 years). All subjects were 20s or 30s. Spinal curvature was assessed using SpinalMouse. The subjects were also divided into a normal group (VAS zero group) and a pain group by VAS results. Statistical analysis was performed by Student's t-test. Significance was defined as p < 0.05. Results: The normal group and pain group included 29 and 60 subjects, respectively. In terms of location of pain, thirty-one subjects felt neck pain, 50 felt pain above the scapula, and 17 felt pain between the thoracic spine and scapula. Thoracic kyphosis and lumbar lordosis in the pain group were significantly higher than those in the normal group (p = 0.013 and p = 0.020, respectively). Thoracic kyphosis in subjects with neck pain or pain above scapula was significantly higher than that in subjects without pain (p = 0.0075 and p = 0.025, respectively). Lumbar lordosis in subjects with pain above the scapula or interscapula was significantly higher than that in subjects without pain (p = 0.016).

Lumbar lordosis of extinct hominins

The lordotic curvature of the lumbar spine (lumbar lordosis) in humans is a critical component in the ability to achieve upright posture and bipedal gait. Only general estimates of the lordotic angle (LA) of extinct hominins are currently available, most of which are based on the wedging of the vertebral bodies. Recently, a new method for calculating the LA in skeletal material has become available. This method is based on the relationship between the lordotic curvature and the orientation of the inferior articular processes relative to vertebral bodies in the lumbar spines of living primates. Using this relationship, we developed new regression models in order to calculate the LAs in hominins. The new models are based on primate group-means and were used to calculate the LAs in the spines of eight extinct hominins. The results were also compared with the LAs of modern humans and modern nonhuman apes. The lordotic angles of australopithecines (41° ± 4), H. erectus (45°) and fossil H. sapiens (54° ± 14) are similar to those of modern humans (51° ± 11). This analysis confirms the assumption that human-like lordotic curvature was a morphological change that took place during the acquisition of erect posture and bipedalism as the habitual form of locomotion. Neandertals have smaller lordotic angles (LA = 29° ± 4) than modern humans, but higher angles than nonhuman apes (22° ± 3). This suggests possible subtle differences in Neandertal posture and locomotion from that of modern humans.
