Quadratus lumborum block has recently been described as an effective and long-lasting analgesic strategy for various abdominal operations, including gynaecological laparoscopy. Despite evidence that the analgesic effect is mediated by indirect paravertebral block and that local anaesthetic spreads to the lumbar paravertebral space, there have been no reports to date of lower limb motor weakness. We present a patient with unilateral hip flexion and knee extension weakness leading to unplanned overnight admission following lateral quadratus lumborum block with 20 ml levobupivacaine 0...

Study Design Controlled laboratory study; pre-test post-test. Background Diffusion-weighted (DW) imaging is a non-invasive magnetic resonance imaging technique that can be used to assess the recruitment of the psoas major (PM) and quadratus lumborum (QL). The recruitment of these muscles during trunk exercises has not been evaluated. Objective To evaluate the diffusion of water movement in several trunk muscles using diffusion-weighted (DW) imaging before and after specific trunk exercises in order to understand the level of recruitment of each muscle during each exercise...

The practice of regional anaesthesia is rapidly changing with the introduction of ultrasound into the working domain of the anaesthesiologist. New techniques are being pioneered. Among the recent techniques, notable are the truncal blocks, for example, the transversus abdominis plane block, rectus sheath block, hernia block and quadratus lumborum block in the abdomen and the pectoral nerves (Pecs) block 1 and 2, serratus anterior plane block and intercostal nerve block. This narrative review covers the brief anatomical discourse along with technical description of the ultrasound-guided truncal blocks...

BACKGROUND AND OBJECTIVES: Effective postoperative analgesia after cesarean delivery enhances early recovery, ambulation, and breastfeeding. In a previous study, we established the effectiveness of the quadratus lumborum block in providing pain relief after cesarean delivery compared with patient-controlled analgesia (morphine). In the current study, we hypothesized that this method would be equal to or better than the transversus abdominis plane block with regard to pain relief and its duration of action after cesarean delivery...

A continuous peripheral nerve block (CPNB) consists of a percutaneously inserted catheter with its tip adjacent to a target nerve/plexus through which local anesthetic may be administered, providing a prolonged block that may be titrated to the desired effect. In the decades after its first report in 1946, a plethora of data relating to CPNB was published, much of which was examined in a 2011 Anesthesia & Analgesia article. The current update is an evidence-based review of the CPNB literature published in the interim...

We performed bilateral transmuscular quadratus lumborum blocks in six cadavers using iodinated contrast and methylene blue. Computed tomography imaging was performed in four cadavers and anatomical dissection was completed in five. This demonstrated spread to the lumbar paravertebral space in 63% of specimens, laterally to the transversus abdominis muscle in 50% and caudally to the anterior superior iliac spine in 63% of specimens. There was no radiographic evidence of spread to the thoracic paravertebral space...

BACKGROUND: Minimal longitudinal data exist regarding the role of lumbar musculature in predicting back pain and function. In cross sectional study designs, there is often atrophy of the segmental multifidus muscle in subjects with low back pain compared with matched controls. However, the cross sectional design of these studies prevents drawing conclusions regarding whether lumbar muscle characteristics predict or modify future back pain or function. OBJECTIVE: The primary objective is to determine if the cross sectional area (CSA) of lumbar muscles predicts functional status or back pain at 6- or 12-month follow-up in older adults with spinal degeneration...

INTRODUCTION AND OBJECTIVES: Quadratus Lumborum block was recently described and has already shown good results as an analgesic technique in abdominal surgeries, having the potential to significantly reduce opioids consumption and be a valid alternative to epidural catheter. We performed a type II Quadratus Lumborum block for analgesia in a septic patient having a sub-total gastrectomy. CASE REPORT: An 80 year-old, ASA III, male patient, weighting 50kg, with a history of arterial hypertension and hypercholesterolemia, diagnosed with sepsis due to purulent peritonitis was submitted to an open laparotomy...

OBJECTIVE: Pisa syndrome (PS) is a common abnormal posture of the trunk in Parkinson disease which is defined as a lateral flexion of the spine in the coronal plane and/or scoliosis. Few studies described focal treatment of dystonia of paraspinal muscles, with unpredictable results, while the participation of quadratus lumborum and external oblique homolateral seem to be interesting. The aim of this study is to estimate the effects of treatment by botulinum toxin of trunk muscles dystonia in PS...

BACKGROUND: Lumbar intervertebral disc degeneration (LDD) frequently occurs in athletes. Associations between LDD and trunk muscles still remain unclear. PURPOSE: This study examined whether there is an association between the prevalence of LDD and the symmetry and size of the cross-sectional areas (CSAs) of the trunk muscles in combat sports athletes. METHODS: Participants in this study were 151 collegiate male combat sports athletes. A total of 755 lumbar intervertebral discs from L1-2 to L5-S1 in 151 athletes were assessed using magnetic resonance imaging (MRI) and a comprehensive grading system of LDD (grades I-V)...

Pelvic drop exercises are often used to strengthen the gluteus medius muscle with the aim of increasing or prioritizing its recruitment. However, the effect of hip rotation on the performance of the action of the gluteus medius is unknown. The aim of the study was to evaluate the effect of hip rotation on the recruitment of the gluteus medius muscle, tensor fasciae latae and quadratus lumborum. Seventeen healthy subjects performed two sets of four repetitions of pelvic drop exercise in random order with lateral (PDLR), medial (PDMR) and neutral (PDN) rotation of the hip...

INTRODUCTION: Atherosclerosis has a complex etiology that leads to arterial obstruction and often results in inadequate perfusion of the distal limbs. Patients with atherosclerosis can have severe complications of this condition, with widespread systemic manifestations, and the operations undertaken are often challenging for anesthesiologists. CASE REPORT: A 79-year-old woman with chronic heart failure and respiratory dysfunction presented with bilateral gangrene of the distal lower extremities with obstruction of the left common iliac artery due to atherosclerosis...

A 69-year-old man with a history of chronic pain and opioid use presented for total hip arthroplasty. In the interests of ensuring early mobilization and pain control, we chose a continuous quadratus lumborum block technique, a novel ultrasound-guided block that has not yet been described for total hip arthroplasty, hypothesizing that it would be motor-sparing. While the perineural catheter was infused, the patient required no IV opioids. He was able to ambulate on the first postoperative day, reporting pain scores between 0 and 3/10...

Staphylococcus Aureus is a Gram-positive cocci bacteria which had been found to be the causative organism in over 88% of patients with primary iliopsoas abscess. We report the case of a 53-year-old diabetic woman with end-stage renal failure diagnosed with left iliopsoas abscess with a catheter-related infection. Computed tomogram (CT) of abdomen and pelvis revealed hypodense lesions of left psoas, iliacus and quadratus lumborum suggestive of psoas abscesses. In addition, osteomyelitis changes at left sacroiliac and hip joint were seen...

The effects of exercise on the core musculature have not been investigated in prepubescents. The main purpose of the present study was to determine the volume and degree of asymmetry of rectus abdominis, obliques and transversus abdominis, quadratus lumborum, iliopsoas, gluteus and paravertebralis muscles in prepubescent tennis players and in untrained boys. The muscle volume was determined using magnetic resonance imaging (MRI) in 7 male prepubescent tennis players and 10 untrained controls (mean age 11.0 ± 0...

Large spinal compressive force combined with axial torsional shear force during asymmetric lifting tasks is highly associated with lower-back injury (LBI). The aim of this study was to estimate lumbar spinal loading and muscle forces during symmetric lifting (SL) and asymmetric lifting (AL) tasks using a whole-body musculoskeletal modelling approach. Thirteen healthy males lifted loads of 7 kg and 12 kg under two lifting conditions (SL and AL). Kinematic data and ground reaction force data were collected and then processed by a whole-body musculoskeletal model...
