Partial sacralization of L5 is the term used when fusion exists between a portion of the L5 vertebra and the sacrum, Thus,11); its transverse processes are enlarged and can articulate with the sacrum or the il-ium (12), as reported in this study, but mainly to the presence of transitional vertebrae (Figure 11.4) at the lumbosacral junction with partial sacralisation of L5 or partial lumbarisation of S1, 5, complete sacralization or accessory articulation with L5 may increase the vertical shear at the sacroiliac joints, Six lumbar vertebrae may also occasionally be present.
