Spine Section, Lateral View

Description

Seen in lateral profile, the vertebral column is arranged as a continuous osseous chain from the upper cervical vertebrae (C1 to C7) through the thoracic (T1 to T12) and lumbar segments (L1 to L5), tapering inferiorly into the sacrum and coccyx. Alternating vertebral bodies and intervertebral discs create the stepped anterior contour, while the posterior margin traces the line of the vertebral arches and spinous processes. The normal sagittal curvatures are evident, with cervical and lumbar lordosis separated by thoracic kyphosis, and the sacrum forming a fixed kyphotic base within the pelvis. Disc spaces appear as pale intervals between adjacent vertebral endplates. A lateral spine section offers the clearest perspective on sagittal alignment, the feature most scrutinized when correlating posture, pain, and degenerative change. Loss of lumbar lordosis with relative disc height reduction at L4 to L5 or L5 to S1 is a common pattern in degenerative disc disease, while exaggerated thoracic kyphosis and anterior wedging point toward compression fracture or Scheuermann-type deformity. This projection also maps directly to the profile clinicians read on standing lateral radiographs when assessing sagittal balance, spondylolisthesis step-offs, and global curvature patterns. Medical educators can pair this artwork with lessons on regional spinal anatomy, spinal biomechanics, and surface landmarking in gross anatomy, kinesiology, or physical therapy curricula. It also fits spine surgery and radiology materials that need a clean reference for describing levels, curves, and disc-related pathology in patient-facing diagrams or journal figures.
