Fig. 2.1 The White and Punjabi three-dimensional space coordinates system When this happens, in a biomechanical approach [2, 3] the spine can be defined as “unstable” since there is a…

Fig. 4.1 L4–S1 posterior fixation (PIF) in a patient affected by L5 spondylolisthesis and bilateral peduncular spondylolysis, with bilateral severe L5 sciatica and mild lower limb paresis. Preoperative 2D CT…

Fig. 7.1 Axial CT scan (bone window) in a patient with bilateral sacroiliac joint degeneration. CT image clearly depicts indirect sign of sacroiliac instability and degeneration, with intra-articular gas related…

Fig. 1.1 All structures show differences in mechanical behaviour during loading versus loading with different stress–strain curves. A part of energy which deforms the VB is not quickly available for…

Fig. 6.1 The main nervous supply to the facet joints is from nerves arising from the medial branches of the dorsal rami of the spinal nerves. Articular branches are given…
