Ultrasound guided quadratus lumborum block or posterior transversus abdominis plane block catheter infusion as a postoperative analgesic technique for abdominal surgery. There are six major functional groups of muscles of the trunk: flexors and extensors in the sagittal plane, right lateral flexors and left lateral flexors in the frontal plane, and right rotators and left rotators in the transverse plane (alternatively, their reverse pelvic actions could be named and considered instead; see Table 3 of blog post article on Motions of the Joints of the Pelvis). The addition of non-steroidal anti-inflammatory medications can help with overall discomfort but has not been shown to have direct effects of the nerve. The transversospinalis is composed of three groups: semispinalis, multifidus, and rotatores (the semispinalis does not attach into the lumbar spine). [5] However, these blocks are minimally invasive and involve injecting medications at the nerves as they cross the iliac crest. Figure 19.

Knowing the structural location of a muscle helps make it possible to understand its action and place it into its functional group for standard (open chain) and reverse (close chain) actions without having to memorize this information. Figure 21. Posterior lumbar interbody fusion (PLIF) aims to fuse two levels of the spine by taking a surgical approach from behind the lumbar spine. Hesham Elsharkawy, Kariem El-Boghdadly, Michael Barrington; Quadratus Lumborum Block: Anatomical Concepts, Mechanisms, and Techniques. As with all muscles, the direction of the muscles line of pull determines the muscles action, and the direction of the muscles fibers essentially determines the line of pull. Longissimus muscle - This is a long muscle with a lumbar vertebral origin at the transverse processes and spinous processes.The longissmus muscle can extend the spine upon bilateral contraction, and unilateral contraction can bend the spinalis group.

Note: The multifidus is the largest muscle of the lumbar spine. Figures 16 through 18 display the muscles of the trunk and pelvis. A further option is with the subcostal oblique anterior approach; the needle insertion is caudal to the transducer, and the trajectory is in-plane, caudallateral to cranialmedial. Stretching a muscle is accomplished by lengthening it, which involves doing the opposite of the muscles mover actions. (A) A posterior schematic illustration of the musculature of the posterior abdominal wall. It forms the bony framework for breathing. This can be performed using an in-plane approach, with a needle insertion medial to the ultrasound transducer, using a posterior-to-anterior trajectory.38 Alternatively an in-plane approach, with an anterior-to-posterior trajectory can be used. The thoracolumbar fascia is part of a myofascial girdle that surrounds the lower torso and is important for posture, load transfer, and stabilization of the lumbar spine. Study interactive 3D models, articles, and quizzes that extend each other. [5][14] In the setting of nerve entrapment between the muscles, activation of the muscles with lumbar extension can reproduce the pain. Quadratus lumborum block approaches are named in reference to injection location in relation to the quadratus lumborum muscle. It also posteriorly tilts and contralaterally rotates the pelvis and elevates the same-side pelvis at the lumbosacral joint. Dysfunction of the superior cluneal nerves is often due to entrapment as the nerves cross the iliac crest this can result in numbness, tingling or pain in the low back and upper buttocks region. [5][11][12] The onset of pain can vary, with some patients report sudden onset of pain with a known inciting incident. Figure 27. Posterior view of the erector spinae musculature of the low back. Explore every muscle, bone, and organ! Therefore, for our purposes, the trunk muscles may be divided into four major structural groups, each in its own quadrant: Viewing the muscles as part of these larger structural groups enhances the therapists understanding of the functional groups of muscle movers.

Anatomy.app unlocks the world of human anatomy. Another type of fusion surgery similar to PLIF is transforaminal lumbar interbody fusion (TLIF), which takes an approach from the side and decreases the risk of nerve injury. The quadratus lumborum muscle is surrounded by a fibrous composite of aponeurotic and fascial tissue: the thoracolumbar fascia. These nerves most commonly originate from the dorsal rami of the L1, L2, and L3 nerve roots. [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 . ); Department of Anaesthesia, Guys and St. Thomas National Health Service Foundation Trust, London, United Kingdom (K.E.-B. IL, The superior cluneal nerves originate from the upper lumbar nerve roots and travel inferiorly through multiple layers of muscles and then traverse through osteofibrous tunnels created by the thoracolumbar fascia and iliac crest. Regardless of which model is accepted, the fascial planes in the abdominal compartment follow the quadratus lumborum and psoas muscles through the medial and lateral arcuate ligaments and the aortic hiatus of the diaphragm, forming the endothoracic fascia. The following outline is provided as an overview of and topical guide to human anatomy: . 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. The science of biomechanics helps explain the causes of cell, tissue, organ and body system disorders, and supports clinicians in the diagnosis, prognosis and evaluation of treatment methods and Rated 0 out of 5.

An understanding of the relevant anatomy and technical aspects of quadratus lumborum block are essential for its effective and safe use. Elsharkawy et al.10 and Dam et al.4 did not observe direct lumbar plexus involvement within the psoas major muscle in all approaches. The male was sectioned at one millimeter intervals In cadaver studies, a small percentage of patients will also have origins at the L4 and L5 nerve roots. [1] Other treatments of superior cluneal nerve dysfunction include both minimally invasive interventions and surgical options. The nerve roots are then gently retracted to the midline to access the posterior disc annulus. [1] Damage from the cluneal nerve can be from direct injury or from entrapment between the muscles or in the osteofibrous tunnel.

This approach was used in two randomized controlled trials that documented an opioid-sparing effect of quadratus lumborum block compared with placebo34 or transversus abdominis plane block35 after caesarean section. The iliohypogastric and ilioinguinal nerves (ventral ramus of L1 with occasional contributions from T12, L2, and L3) depart through the proximal and lateral aspect of the psoas major muscle and traverse the ventral surface of quadratus lumborum (fig. 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. Local anesthetic systemic toxicity: A review of recent case reports and registries. A catheter inserted into this plane can extend analgesic duration and can be an alternative to epidural analgesia. Similarly, Elsharkawy et al.10 replicated a subcostal anterior quadratus lumborum approach at L12 level using a parasagittal oblique approach and found cranial spread to involve T712. 3).5 The lumbar interfascial triangle provides a theoretical pathway for injectate spread deep to the thoracolumbar fascia. A catheter inserted into this plane can extend analgesic duration and can be an alternative to epidural analgesia. [1][5] Many patients also have tender points located around the posterior iliac crest, approximately 7cm from midline which correlates with cadaver studies demonstrating the location at which the nerves cross the iliac crest.
