Delayed Treatment of a Traumatic Lumbosacral Dislocation With Associated Injuries: A Case Report.

JBJS Case Connect 2021 Apr 19;11(2). Epub 2021 Apr 19.

Department of Surgery, Sir H.N. Reliance Foundation Hospital, Girgaon, Mumbai, India.

Case: A 41-year-old woman sustained a degloving injury over her lumbosacral and perineal region with fractures of her right tibia and fibula. After diversion colostomy and osteosynthesis for the fractures at a primary center, a missed grade 2 lumbosacral dislocation was diagnosed at a tertiary center and the degloving injury was treated with debridement and skin grafting. After 5 months, the dislocation had progressed to grade 4 and she underwent delayed posterior lumbosacral reduction, interbody fusion, and L4-S1 fixation, with superior gluteal artery perforator flap and subsequent colostomy closure, with good outcomes (Oswestry Disability Index 10%) at the 3-year follow-up.

Intramuscular hematoma in rhabdomyolysis patients treated with low-molecular-weight heparin: Report of two cases.

World J Clin Cases 2021 Apr;9(12):2838-2844

Department of Critical Care Medicine, Nanping First Hospital Affiliated to Fujian Medical University, Nanping 353000, Fujian Province, China.

Background: Rhabdomyolysis is a serious complication of heat stroke. Unlike that in acute kidney injury, the risk of muscle bleeding in rhabdomyolysis is often ignored and can substantially increase the widespread use of anticoagulants, leading to the formation of intramuscular hematoma.

Case Summary: During the summer, a middle-aged man and an elderly man were diagnosed with heat stroke, rhabdomyolysis, and acute renal impairment. Read More

Influence of lumbosacral transitional vertebrae on spinopelvic parameters using biplanar slot scanning full body stereoradiography-analysis of 291 healthy volunteers.

J Orthop Sci 2021 May 6. Epub 2021 May 6.

Niigata University Hospital, Japan.

Background: Proper identification of lumbosacral transitional vertebrae (LSTV) is important to characterize the relationship between the transitional segment and adjacent levels. Classical classification schemes are inaccurate with respect to the whole spine. We propose a precise vertebral numbering method and investigated the relationship between LSTV and whole-body sagittal alignment. Read More

Flexing a standard hinge-powered operating table for lumbosacral three-column osteotomy (3-CO) site closure in 84 consecutive patients.

Neurosurg Rev 2021 May 8. Epub 2021 May 8.

Department of Neurosurgery, Medical University of Innsbruck, Anichstrasse 35, MZA 3rd floor, Tyrol, 6020, Austria.

Three-column osteotomy (3-CO) is a powerful technique in adult deformity surgery, and pedicle subtraction osteotomy (PSO) is the workhorse to correct severe kyphotic spinal deformities. Aging of the population, increasing cases of iatrogenic flat back deformities and understanding the importance of sagittal balance have led to a dramatic increase of this surgical technique. Surgery, however, is demanding and associated with high complication rates so that every step of the procedure requires meticulous technique. Read More

Distal Stimulation Site at the Medial Tibia for Saphenous Nerve Somatosensory Evoked Potentials (DSn-SSEPs) in Lateral Lumbar Spine Procedures.

Neurodiagn J 2021 May 5:1-14. Epub 2021 May 5.

Axis Neuromonitoring, Richardson, Texas.

Lateral lumbar interbody fusion procedures are performed with multimodality neuromonitoring of the femoral nerve to prevent lumbosacral plexus and peripheral nerve injury from positioning, dilation, retraction, and hardware implantation. The integrity of the femoral nerve can be continuously assessed during these procedures by Somatosensory Evoked Potentials of the Saphenous nerve (Sn-SSEPs). Sn-SSEPs are technically challenging to acquire and necessitate advanced troubleshooting skills with a more rigid anesthetic regimen and physiological parameters. Read More

Roadmap for Motor Evoked Potential (MEP) Monitoring for Patients Undergoing Lumbar and Lumbosacral Spinal Fusion Procedures.

Neurodiagn J 2021 Mar;61(1):27-36

Medical Department, SpecialtyCare, Brentwood, Tennessee.

MEPs are recommended for patients undergoing lumbar and lumbosacral procedures in which intraoperative neuromonitoring (IONM) is being utilized. While electromyography (EMG) provides critical nerve root proximity information, spontaneous EMG discharges are relatively poor at reliably diagnosing spinal nerve root dysfunction. In contrast, research indicates that MEPs are both sensitive and specific in diagnosing evolving spinal nerve root dysfunction. Read More

Department of Physical Therapy, College of Medicine, National Cheng Kung University, Tainan 701, Taiwan.

The abdominal expansion (AE) strategy, involving eccentric contraction of the abdominal muscles, has been increasingly used in clinical practices; however, its effects have not been rigorously investigated. This study aimed to investigate the immediate effects of the AE versus abdominal drawing-in (AD) strategy on lumbar stabilization muscles in people with nonspecific low back pain (LBP). Thirty adults with nonspecific LBP performed the AE, AD, and natural breathing (NB) strategies in three different body positions. Read More

Lumbosacral plexopathy due to pelvic hematoma after extracorporeal membrane oxygenation: A case report.

Medicine (Baltimore) 2021 Apr;100(17):e25698

Department of Neurology, Washington University School of Medicine, Saint Louis, MO.

Rationale: Peripheral nerve injury related to vascular complications associated with extracorporeal membrane oxygenation (ECMO) is perhaps underappreciated. Compared to the well-described central nervous system complications of ECMO, brachial plexopathy and lumbosacral plexopathy have rarely been reported. We report this case to heighten awareness of lumbosacral plexus injury due to pelvic hematoma formation after ECMO. Read More

Disorders of Secondary Neurulation : Mainly Focused on Pathoembryogenesis.

J Korean Neurosurg Soc 2021 Apr 29. Epub 2021 Apr 29.

Neuro-oncology Clinic, Center for Rare Cancers, National Cancer Center, Goyang, Korea.

Recent advancements in basic research on the process of secondary neurulation and increased clinical experience with caudal spinal anomalies with associated abnormalities in the surrounding and distal structures shed light on further understanding of the pathoembryogenesis of the lesions and led to the new classification of these dysraphic entities. We summarized the changing concepts of lesions developed from the disordered secondary neurulation shown during the last decade. In addition, we suggested our new pathoembryogenetic explanations for a few entities based on the literature and the data from our previous animal research. Read More

Axial Spondyloarthritis is associated with changes in lumbosacral loading during daily activities.

Clin Biomech (Bristol, Avon) 2021 Apr 3;85:105347. Epub 2021 Apr 3.

Human Movement Biomechanics Research Group, Department of Movement Sciences, KU Leuven, Belgium.

Background: There is currently little insight in lumbar spine loading during activities of daily living in patients with axial spondyloarthritis. Furthermore, it is unclear how inflammation or ankylosis-related mobility limitations in patients with axial spondyloarthritis affect lumbosacral loading, and if lumbar movement profiles have an effect on lumbosacral loading as well. Therefore, the aim of this study is to get more insight in the differences in peak and cumulative lumbosacral loading in patients with axial spondyloarthritis during activities of daily living.

Calibration and validation of a novel hybrid model of the lumbosacral spine in ArtiSynth-The passive structures.

PLoS One 2021 26;16(4):e0250456. Epub 2021 Apr 26.

Chair of Product Development, Department of Mechanical Engineering, Ruhr-University Bochum, Bochum, Germany.

In computational biomechanics, two separate types of models have been used predominantly to enhance the understanding of the mechanisms of action of the lumbosacral spine (LSS): Finite element (FE) and musculoskeletal multibody (MB) models. To combine advantages of both models, hybrid FE-MB models are an increasingly used alternative. The aim of this paper is to develop, calibrate, and validate a novel passive hybrid FE-MB open-access simulation model of a ligamentous LSS using ArtiSynth. Read More
