The lumbar fibres of iliocostalis lumborum and longissimus thoracis are more angulated relative to the vertebral column than the multifidus or the upper erector spinae, with a substantial increase in obliquity towards the L4-L5 region (Macintosh and Bogduk 1991).

Access from a posterior approach requires palpation through the skin, a substantial amount of subcutaneous tissue, the thoracolumbar fascia, erector spinae aponeurosis, and finally through the iliocostalis lumborum and quadratus lumborum muscles (Frazer 1940; Shellshear and Macintosh 1949) (Figure 4).
