35 Bilateral pars interarticularis defects of L4 with spondylolisthesis. (A) Lateral radiograph shows defects in the pars (arrow). (B) Axial CT image shows the bilateral defects (arrows). (C,D) Sagittal reconstructed CT images show the defects in the pars (arrows). 25 2 Anatomic considerations Fig. 37 Sacralization of L5. A horizontal line drawn across the iliac crests passes through or close to the L4–L5 junction. Fig. 36 Lumbar styloid processes of L1 (arrows). Fig. 38 Lumbarization of S1. When such an anomaly is encountered, three methods can be used to determine the correct lumbar levels.

Further increases in force cause microfractures in bones and microtears in ligaments. A cessation of force does not result in a return of the structure to its normal resting state, and a permanent deformity occurs. This is referred to as the plastic zone. A classic example of this is encountered in children with plastic bowing injuries of the extremities. Once sufficient microtrauma has occurred to the structural system, catastrophic failure (manifested as gross fracture, ligamentous rupture, or both) occurs as the failure zone is reached.

Vertebra T11 and T12 resemble lumbar vertebrae; their short transverse processes lack facets for rib articulations, and their bodies are quite large [1–5]. Indeed, the absence of ribs from T12, a common anomaly, can result in mistaken identification of this vertebra as L1. Lumbar vertebrae The lumbar vertebrae are the largest and heaviest segments of the presacral part of the vertebral column (Figs. 34). 23 2 Anatomic considerations A B Fig. 30 Typical lumbar vertebra (L3), anterior view.
