Quadratus lumborum

Michael Akerman, Nada Pejčić, Ivan Veličković
The use of truncal nerve blocks has been described since 2001. Since then, there have been many studies trying to understand the ideal clinical scenarios for its use. Since 2001, the transversus abdominis plane block has evolved in many ways including from landmark based technique to ultrasound guided and more recently, into the quadratus lumborum (QL) block. Its anatomical placement, concentration of local anesthetic, volume of local anesthetic, and anatomic placement have all been raised as clinical questions...

OBJECTIVES: Quadratus Lumborum Block in contrast to Transversus Abdominis Plane Block contains a unique component which not only stops somatic pain but also inhibits visceral pain by spreading the local anesthetic to the paravertebral space. This study was designed to determine whether performing the Quadratus Lumborum Block type I in patients un-dergoing cesarean section would be associated with both decreased morphine consumption and decreased pain levels in the postoperative 48-hour period...

Background and Purpose: Understanding the role and significance of trunk and upper extremity muscles in paraplegic gait can help in designing more effective assistive devices for these patients and also provides valuable information for improving muscle strengthening programs. Methods: In a patient with a spinal cord injury (SCI) who could walk independently (rating scale of ambulatory capacity, 9) with the aid of bilateral ankle-foot orthosis and a walker, the kinematics, kinetics and electromyographic (EMG) activities of 16 muscles from the trunk and upper and lower extremities were recorded during gait...

BACKGROUND AND OBJECTIVES: Several types of quadratus lumborum block (QLB) are used for postoperative analgesia and are believed to be effective against both somatic and visceral pain via a local anesthetic (LA) effect in the paravertebral space (PVS). However, it remains unclear whether all QLB techniques result in LA spread into the PVS. We hypothesized that LA administered via intramuscular QLB would spread into the paravertebral space and investigated the spread and sensory block area of LA in intramuscular QLB...

BACKGROUND AND OBJECTIVES: The quadratus lumborum (QL) block has been widely used for acute postoperative pain management after numerous surgical procedures including urological, abdominal, gynaecological and orthopaedic surgical procedures. The local anaesthetic spread in this area can provide unilateral sensory block in T6-L2 dermatomes. We performed bilateral quadratus lumborum block for the management of acute pain after the uterine artery embolization (UAE). METHODS: A 43-year-old woman was admitted to the gynaecology department of Mother and Child Hospital, University Medical Center, for uterine artery embolization...

BACKGROUND: Imaging in side bending, supine, traction, fulcrum, and push prone are examples of methods used to evaluate the curve reduction of scoliotic spine. However, being able to determine spine curve flexibility from MRI would eliminate the need of additional X-ray radiation related to radiograph acquisition in side-bending. PURPOSE/HYPOTHESIS: To find specific texture features of lumbar postural muscles on MRI that can distinguish flexible from rigid lumbar scoliotic curves...

The deep core muscles are often neglected or improperly trained in athletes. Improper function of this musculature may lead to abnormal spinal loading, muscle strain, or injury to spinal structures, all of which have been associated with increased low back pain (LBP) risk. The purpose of this study was to identify potential strategies used to compensate for weakness of the deep core musculature during running and to identify accompanying changes in compressive and shear spinal loads. Kinematically-driven simulations of overground running were created for eight healthy young adults in OpenSim at increasing levels of deep core muscle weakness...

Abdominal field blocks are commonly used as part of multimodal analgesia for post-operative pain relief in patients undergoing abdominal surgery. Conventionally, transversus abdominis plane block is used, but has the disadvantage of limited spread only to T10-T12 segments, providing only partial pain relief. The new quadratus lumborum (QL) block has the advantage of providing wider sensory block from T6 to L1 and thus has an evolving role in opioid-free anaesthesia. Opioid-induced cough depression, urinary retention, and drowsiness can be problematic in patients with Prune belly syndrome, who have deficient abdominal muscles and myriad of genitourinary problems...

BACKGROUND: The anterior iliac crest (AIC) is one of the most common sites for harvesting autologous bone, but the associated postoperative pain can result in significant morbidity. Recently, the transmuscular quadratus lumborum block (TQL) has been described to anesthetize the thoraco-lumbar nerves. This study utilizes a combination of cadaveric models and clinical case studies to evaluate the dermatomal coverage and analgesic utility of TQL for AIC bone graft donor site analgesia. METHODS: Ten ultrasound-guided TQL injections were performed in five cadaver specimens using a lateral-to-medial transmuscular approach...

BACKGROUND: Landmark and ultrasound-guided transversus abdominis plane blocks have demonstrated an opioid-sparing effect postoperatively after cesarean delivery. The more posterior quadratus lumborum (QL) might provide superior local anesthetic spread to the thoracolumbar fascia and paravertebral space. The aim of our study was to evaluate the efficacy of the QL block after cesarean delivery. METHODS: A randomized, double-blind, controlled trial was performed. Forty parturients undergoing cesarean delivery received bilateral ultrasound-guided QL blocks with either 2 mg/mL ropivacaine or saline postoperatively...

Ultrasound (US)-guided transversalis fascia plane block (TFPB) was first described by Hebbard as a technique for blockade of T12-L1 nerves. Although this technique appears similar to the quadratus lumborum 1 block, the point of injection is more caudal and anterior, specifically targeting ilioinguinal and iliohypogastric nerves. There are only few published data on US-guided TFPB demonstrating effective postoperative analgesia in iliac crest bone graft harvesting. We report the use of US-guided TFPB in a patient undergoing inguinal herniorrhaphy...

BACKGROUND: The question that was asked in the study was whether a training routine based on curl-up exercises with a load provided by body mass of the person increases local muscle strength or local muscle endurance. OBJECTIVE: The aim of this study was to evaluate the effect of 4 weeks training based on a small load and low movement velocity on electrical activity (EMG), cross-sectional area (CSA) of core stabilisers. METHODS: The EMG activity was measured in the rectus abdominis (RA), obliquus abdominis externus and erector spinae (ES) muscles...

Autogenous bone grafting is the gold standard for reconstructing craniofacial defects. Mandibular defects are reliably reconstructed with free nonvascularized bone, such as from the posterior iliac crest (PIC). In light of improved imaging, including 3-dimensional computed tomography scanning, a more accurate defect estimation is possible. A strong understanding of bone graft available is necessary. The purpose of this study was an updated review of the dissection and quantification of the amount of bone that can be safely harvested...

BACKGROUND: Muscle stiffness of the lumbar back muscles in low back pain (LBP) patients has not been clearly elucidated because quantitative assessment of the stiffness of individual muscles was conventionally difficult. This study aimed to examine the association of LBP with muscle stiffness assessed using ultrasonic shear wave elastography (SWE) and muscle mass of the lumbar back muscle, and spinal alignment in young and middle-aged medical workers. METHODS: The study comprised 23 asymptomatic medical workers [control (CTR) group] and 9 medical workers with LBP (LBP group)...
