The dome shaped thoracic cage provides the necessary rigidity for organ protection, weight support for the upper limbs and anchorage for muscles. The left and right lower back muscles (erector spinae) are dissected off the lamina on both sides and at multiple levels. The most common overlapping pathologies include facet joint pain, sacroiliac joint dysfunction, and lumbosacral radiculopathy. Before memorizing the detailed actions of each muscle of the lumbar spine, it is helpful first to visualize each muscle within its larger structural and functional groups. Originally described for thoracic analgesia when performed at the T5 transverse process, the ESP block can provide abdominal analgesia if performed at lower thoracic levels because the erector spinae muscles extend to the lumbar spine. Figure 27. [5] Note: This is the fifth in a series of 8 blog post articles on the anatomy and physiology of the lumbar spine and pelvis. Severe lower back pain combined with neurological symptoms of leg pain that persist despite months of nonsurgical treatments may lead to the consideration of PLIF as a surgical treatment.

Although adverse effects have been reported following extremely high levels of exposure for very short durations (Hagberg, 1981, Ex. Caudally, this fascial layer is continuous with the fascia iliaca.24, The three-layered model is the most commonly used. Keeping your learning focused for a strong foundation for your medical career. Muscles that perform right or left rotation must have a horizontal component to their fiber direction; in fact, it can be helpful to view them as partially wrapping horizontally around the trunk. 1B). It is also helpful to view the muscles as being located either on the right side or the left side of the trunk. Knowing the mover actions allows the therapist to ask the client to contract and engage the target muscle so that it palpably hardens. Quadratus lumborum block as an alternative to lumbar plexus block for hip surgery: A report of 2 cases. Anterior quadratus lumborum block injectate may spread to the lumbar nerve roots and branches in addition to the thoracic paravertebral space.4,911 Posterior quadratus lumborum blocks appear to demonstrate their clinical effect by injectate spread along the middle thoracolumbar fascia intertransverse area.10,26 Lateral quadratus lumborum blocks are associated with injectate spread to the transversus abdominis muscle plane and to subcutaneous tissue,26 although clinical reports refer to a more extensive distribution.31,32,35,41 At present, there is insufficient evidence to recommend one approach and transducer positioning over another for individual patient populations and specific surgical types. An all-in-one platform for an efficient way to learn and understand anatomy. To gain these skills, the student learns best with good anatomical models or a well-dissected cadaver, at the laboratory bench, guided and instructed by experienced teachers, and inspired toward self-directed, diligent reading.

Sensory innervation of human thoracolumbar fascia: An immunohistochemical study. [3][4] After they branch off the dorsal rami, they go pass through the erector spinae muscle, psoas major, paraspinal muscles, and then inferior latissimus dorsi to reach the iliac crest. Recent evidence suggests that rather than being a passive scaffold, fascial tissue is more complex, with rich vascular and sensory innervation. Courtesy Joseph E. Muscolino. Cranially, the anterior layer of the thoracolumbar fascia (the transversalis fascia in the two-layer model) divides into two layers. Typical needle length would range from 80 to 150 mm depending on patient body habitus. The external image and ultrasound images show the ultrasound probe position with a solid arrow indicating the needle trajectory for a lateral quadratus lumborum block and the dashed line indicating the needle trajectory for a posterior quadratus lumborum block approach. The transversalis fascia lines the peritoneal surface of the transversus abdominis muscle and wraps the anterior aspect of the investing fascia (epimysium) of both quadratus lumborum and psoas muscles. Overall, local anesthetic injected between the transversalis fascia and the quadratus lumborum muscle may spread to the thoracic paravertebral space, and the vertebral level of injection will influence the extent of cranial spread. Instrumentation includes the placement of two, Posterior Lumbar Interbody Fusion (PLIF) Surgery, Pseudoarthrosis from a prior spinal fusion surgery that did not result in a fusion. Originally described for thoracic analgesia when performed at the T5 transverse process, the ESP block can provide abdominal analgesia if performed at lower thoracic levels because the erector spinae muscles extend to the lumbar spine.
