Lumbar Radiofrequency Ablation Interfering With S1 Dorsal Root Ganglion Stimulation Systems: Experience From Two Cases.

Pain Pract 2020 Apr 19. Epub 2020 Apr 19.

The Spine & Pain Institute of New York, New York, New York, U.S.A.

Background: Dorsal root ganglion stimulation (DRG-S) has emerged as a treatment for complex regional pain syndrome (CRPS) of the lower extremities, and recent small studies are demonstrating its potential efficacy in pain syndromes that are traditionally considered nociceptive in nature, such as axial low back pain. While improvements in neuromodulation technology have been substantial over the past decade, with DRG-S systems patients occasionally require additional interventional pain treatments for treatment of pain from other sources. Radiofrequency ablation (RFA) of medial branch nerves innervating the facet joints is an accepted therapy for pain arising from the facet joints. Read More

Spinal cord stimulation failure: evaluation of factors underlying hardware explantation.

J Neurosurg Spine 2019 Oct 4:1-6. Epub 2019 Oct 4.

2Mayfield Clinic, Cincinnati, Ohio; and.

Objective: Spinal cord stimulation has been shown to improve pain relief and reduce narcotic analgesic use in cases of complex refractory pain syndromes. However, a subset of patients ultimately undergoes removal of the spinal cord stimulator (SCS) system, presumably because of surgical complications or poor efficacy. This retrospective study addresses the paucity of evidence regarding risk factors and underlying causes of spinal cord stimulation failures that necessitate this explantation. Read More

Intravenous Regional Anesthesia: A Historical Overview and Clinical Review.

J Anesth Hist 2019 07 7;5(3):99-108. Epub 2018 Nov 7.

Center of Anesthesiology and Intensive Care Medicine, Department of Anesthesiology, University Medical Centre Hamburg-Eppendorf, Martinistrasse 52, 20251 Hamburg, Germany. Electronic address:

Intravenous regional anesthesia (IVRA) is an established, safe and simple technique, being applicable for various surgeries on the upper and lower limbs. In 1908, IVRA was first described by the Berlin surgeon August Bier, hence the name "Bier's Block". Although his technique was effective, it was cumbersome and fell into disuse when neuroaxial and percutaneous plexus blockades gained widespread popularity in the early 20 century. Read More

Proximal myofascial pain in patients with distal complex regional pain syndrome of the upper limb.

J Bodyw Mov Ther 2019 Jul 21;23(3):547-554. Epub 2019 Feb 21.

Department of Physical Therapy, Recanati School for Community Health Professions, Faculty of Health Sciences, Ben-Gurion University of the Negev, Beer Sheva, Israel. Electronic address:

Background: Patients suffering from complex regional pain syndrome (CRPS) endure myofascial-related pain in at least 50% of cases.

Aims: To evaluate the association of upper limb CRPS with myofascial pain in muscles that might influence arm or hand pain, and to evaluate whether the paraspinal skin and subcutaneous layers' tenderness and allodynia are associated with CRPS.

Methods: A case-control study comprising 20 patients presenting with upper limb CRPS, and 20 healthy controls matched for sex and age, were evaluated in the thoracic paraspinal area and myofascial trigger points (MTrPs) (infraspinatus, rhomboids, subclavius, serratus posterior superior and pectoralis minor) via a skin rolling test.

A Prospective, Randomized Cross-Over Trial of T2 Paravertebral Block as a Sympathetic Block in Complex Regional Pain Syndrome.

Pain Physician 2019 09;22(5):E417-E424

Department of Anesthesiology and Pain Medicine, Daejeon St. Mary's Hospital, College of Medicine, The Catholic University of Korea, Seoul, Republic of Korea.

Background: Sympathetic block is commonly performed in clinical practice for management of intractable pain conditions. However, stellate ganglion block (SGB) alone often does not achieve sufficient sympatholysis of the upper extremity. The paravertebral space continues up to the cervical sympathetic chain and includes the stellate ganglion. Read More

Arthroscopic treatment of elbow osteoarthritis.

Orthop Traumatol Surg Res 2019 12 23;105(8S):S235-S240. Epub 2019 Sep 23.

15, rue Ampère, 92500 Rueil-Malmaison, France.

Elbow osteoarthritis chiefly affects heavy manual labourers and athletes and may be primary or post-traumatic. Arthroscopic debridement for primary elbow osteoarthritis reliably produces pain relief, motion range gains, and good functional outcomes. Total elbow arthroplasty, in contrast, is considered a salvage option in this patient population, as activities must be restricted to protect the implant. Read More

Complex Regional Pain Syndrome: Current Diagnostic and Treatment Considerations.

Curr Sports Med Rep 2019 Sep;18(9):325-329

Houston Methodist Orthopedics and Sports Medicine, Houston, TX.

Complex Regional Pain Syndrome is a severe complication of extremity fracture or other injury. Patients who develop this show marked hyperalgesia and allodynia, altered vasomotor, sudomotor and trophic changes. The condition affects women more than men and is most common in those between the ages of 50 and 70 years but can be seen in younger athletes. Read More

Waves of Pain Relief: A Systematic Review of Clinical Trials in Spinal Cord Stimulation Waveforms for the Treatment of Chronic Neuropathic Low Back and Leg Pain.

World Neurosurg 2019 Nov 30;131:264-274.e3. Epub 2019 Jul 30.

Department of Neurosurgery, Vicki and Jack Farber Institute for Neuroscience, Thomas Jefferson University, Philadelphia, Pennsylvania, USA.

In the United States, chronic low back pain affects up to 37% of adults and is a multibillion dollar health care expenditure. Spinal cord simulation (SCS) has been established as an effective treatment alternative for chronic neuropathic low back and leg pain, especially for patients with failed back surgery syndrome or chronic regional pain syndrome. The field of SCS has rapidly advanced such that analgesia can now be achieved through numerous different waveforms, each claiming to offer improved outcomes. Read More

Outcomes of Sympathetic Blocks in the Management of Complex Regional Pain Syndrome: A Retrospective Cohort Study.

Anesthesiology 2019 10;131(4):883-893

From the Departments of Pain Management (J.C., V.S., M.G., O.T.C., F.Z., R.W.R.) Neurosciences (J.C.) Quantitative Health Sciences and Outcomes Research (J.Y., D.Y., E.J.M.), Cleveland Clinic, Cleveland, Ohio Department of Anesthesiology, Perioperative and Pain Medicine, Stanford University School of Medicine, Palo Alto, California (V.S.).

Background: Sympathetic dysfunction may be present in complex regional pain syndrome, and sympathetic blocks are routinely performed in practice. To investigate the therapeutic and predictive values of sympathetic blocks, the authors test the hypotheses that sympathetic blocks provide analgesic effects that may be associated with the temperature differences between the two extremities before and after the blocks and that the effects of sympathetic blocks may predict the success (defined as achieving more than 50% pain reduction) of spinal cord stimulation trials.

Methods: The authors performed a retrospective study of 318 patients who underwent sympathetic blocks in a major academic center (2009 to 2016) to assess the association between pain reduction and preprocedure temperature difference between the involved and contralateral limbs. Read More

Highlighting the Role of Biomarkers of Inflammation in the Diagnosis and Management of Complex Regional Pain Syndrome.

Mol Diagn Ther 2019 10;23(5):615-626

Center for Pain Medicine, Department of Anesthesiology, Erasmus MC University Medical Center Rotterdam, Rotterdam, The Netherlands.

Complex regional pain syndrome (CRPS) is characterized by continuous pain that is often accompanied by sensory, motor, vasomotor, sudomotor, and trophic disturbances. If left untreated, it can have a significant impact on the quality of life of patients. The diagnosis of CRPS is currently based on a set of relatively subjective clinical criteria: the New International Association for the Study of Pain clinical diagnostic criteria for CRPS. Read More

Parallels between lumbosacral radiculopathy and complex regional pain syndrome: α1-adrenoceptor upregulation, reduced dermal nerve fibre density, and hemisensory disturbances in postsurgical sciatica.

Pain 2019 08;160(8):1891-1900

Psychology Unit, College of Science, Health, Engineering and Education, Murdoch University, Perth, Australia.

Residual lower-limb pain after low back surgery (postsurgical sciatica) and complex regional pain syndrome (CRPS) involving a lower limb are separate conditions but may share some mechanisms (eg, tissue inflammation, neuroimmune disturbances, and central neuroplasticity). As adrenergically evoked pain contributes, in part, to CRPS, whether an adrenergic mechanism also contributes to postsurgical sciatica was investigated in this study. Immunohistochemistry was used to identify α1-adrenoceptors (α1-AR) on nerve fibres and other targets in the affected and contralateral skin of 25 patients with postsurgical sciatica, and α1-AR expression was investigated in relation to pain and pinprick hyperalgesia after intradermal injection of the α1-AR agonist phenylephrine.

Complex regional pain syndrome I (CRPS-I) is a chronic painful pathology still undertreated. CTK 01512-2 is a recombinant version of the spider peptide Phα1β, and it functions as a voltage-gated calcium channel blocker and a transient receptor potential ankyrin 1 (TRPA1) antagonist with antinociceptive effect in different pain models. Here, we investigate the mechanisms involved in the acute and chronic nociceptive phases of a model of CPRS-I in mice and assess the antinociceptive effect of CTK 01512-2 using this model. Read More
