CRPS: what's in a name? Taxonomy, epidemiology, neurologic, immune and autoimmune considerations.

Reg Anesth Pain Med 2019 Mar;44(3):376-387

Department of Pain Management, Cleveland Clinic, Cleveland, OH 44024, USA

This account of the condition now termed complex regional pain syndrome (CRPS) spans approximately 462 years since a description embodying similar clinical features was described by Ambroise Paré in 1557. While reviewing its historical origins, the text describes why it became necessary to change the taxonomies of two clinical syndromes with similar pathophysiologies to one which acknowledges this aspect but does not introduce any mechanistic overtones. Discussed at length is the role of the sympathetic component of the autonomic nervous system (ANS) and why its dysfunction has both directly and indirectly influenced our understanding of the inflammatory aspects of CRPS.

Compared to limb pain of other origin, ultrasonographic osteodensitometry reveals loss of bone density in complex regional pain syndrome.

Pain 2019 Feb 8. Epub 2019 Feb 8.

Dept. of Endocrine Research, Medical Hospital I, BG University Hospitals Bergmannsheil Bochum.

Local osteopenia and altered bone metabolism are major complications of complex regional pain syndrome (CRPS), but quantitative assessment is difficult unless using X-ray or dual-energy X-ray absorptiometry. Ultrasound-based measurement of bone density (UBD) is a possible alternative, but has never been used to detect unilateral disease such as CRPS. Therefore, the main outcome measure of this prospective study was the diagnostic utility of UBD in patients with lower limb CRPS. Read More

The Role of the Peripheral Nerve Surgeon in the Treatment of Pain.

Neurotherapeutics 2019 Jan;16(1):9-25

Division of Plastic and Reconstructive Surgery, Washington University in St. Louis, St. Louis, MO, USA.

Pain is a frequent cause of physician visits. Many physicians find these patients challenging because they often have complicated histories, emotional comorbidities, confusing examinations, difficult problems to fix, and the possibility of factitious complaints for attention or narcotic pain medications. As a result, many patients are lumped into the category of chronic, centralized pain and relegated to pain management. Read More

Perfusion index as a reliable parameter of vasomotor disturbance in complex regional pain syndrome.

Br J Anaesth 2018 Nov 24;121(5):1133-1137. Epub 2018 Aug 24.

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

Background: Discrepancy between a patient's subjective thermal symptoms and objective measured temperature value is common in complex regional pain syndrome (CRPS) in clinical settings. For that reason, the diagnostic validity of a single temperature measurement method has been criticised. Several studies showed that the perfusion index (PI), which is derived from pulse oximetry, is a more sensitive and earlier indicator of sympathetic blockade than temperature measurement. Read More

Short-Term Glucocorticoid Treatment Normalizes the Microcirculatory Response to Remote Ischemic Conditioning in Early Complex Regional Pain Syndrome.

Pain Pract 2019 Feb 5;19(2):168-175. Epub 2018 Nov 5.

Department of Pain Medicine, BG University Hospital Bergmannsheil GmbH, Ruhr University, Bochum, Germany.

Background: The early phase of complex regional pain syndrome (CRPS) is characterized by an inflammatory state and therefore often treated with anti-inflammatory acting glucocorticoids. Recently, we demonstrated that remote ischemic conditioning (RIC), a cyclic application of nondamaging ischemia on a remote extremity, reduces blood flow and increases oxygen extraction in the CRPS-affected extremity.

Aim: The aim of the presented study was to analyze the effect of short-term pain treatment including glucocorticoid pulse treatment on the RIC-induced perfusion parameters. Read More

An Integrative Neuroscience Framework for the Treatment of Chronic Pain: From Cellular Alterations to Behavior.

Front Integr Neurosci 2018 23;12:18. Epub 2018 May 23.

Department of Psychology, Hofstra University, Hempstead, NY, United States.

Chronic pain can result from many pain syndromes including complex regional pain syndrome (CRPS), phantom limb pain and chronic low back pain, among others. On a molecular level, chronic pain syndromes arise from hypersensitization within the dorsal horn of the spinal cord, a process known as central sensitization. Central sensitization involves an upregulation of ionotropic and metabotropic glutamate receptors (mGluRs) similar to that of long-term potentiation (LTP). Read More

Epidemiology of complex regional pain syndrome in Korea: An electronic population health data study.

PLoS One 2018 4;13(6):e0198147. Epub 2018 Jun 4.

Department of Anesthesiology and Pain Medicine, Wonkwang University College of Medicine, Iksan, Republic of Korea.

Chronic regional pain syndrome (CRPS) is an inflammatory and neuropathic pain disorder characterized by the involvement of the autonomic nervous system with sensory, autonomic, motor, skin, and bone changes. At present, universally accepted consensus criteria for CRPS are not yet established, despite the diagnostic criteria proposed by the International Association for the Study of Pain (IASP). Various hypotheses for the pathophysiology of CRPS have been proposed; as a result, current therapeutic modalities are varied. Read More

Approach to the Patient with Disproportionate Pain.

Bull Hosp Jt Dis (2013) 2018 Jun;76(2):123-132

Faced with a patient who presents with unexplained disproportionate pain, a surgeon may be tempted to diagnose a low pain threshold, malingering, poor coping, anxiety, or other emotional condition. However, a variety of conditions must be ruled out before the orthopedist can prescribe watchful waiting. Computed tomography and magnetic resonance imaging can detect occult fractures, acute spinal conditions or vascular occlusions, but early on are inadequate to diagnose a compartment syndrome, necrotizing fasciitis, or reflex sympathetic dystrophy (RSD).

Motor Cortex Stimulation for Deafferentation Pain.

Curr Pain Headache Rep 2018 May 23;22(6):45. Epub 2018 May 23.

Department of Neurosurgery, University of Illinois at Chicago, 912 South Wood Street, 451-N NPI, (MC 799), Chicago, IL, 60612, USA.

Purpose Of Review: Since the early 1990s, motor cortex stimulation (MCS) has been a unique treatment modality for patients with drug-resistant deafferentation pain. While underpowered studies and case reports have limited definitive, data-driven analysis of MCS in the past, recent research has brought new clarity to the MCS literature and has helped identify appropriate indications for MCS and its long-term efficacy.

Recent Findings: In this review, new research in MCS, repetitive transcranial magnetic stimulation (rTMS), and transcranial direct current stimulation (tDCS) are analyzed and compared with historical landmark papers. Read More

Yi-Tai Jou

Kaohsiung J Med Sci 2018 Apr 8;34(4):231-237. Epub 2018 Feb 8.

Department of Endodontics School of Dental Medicine University of Pennsylvania Philadelphia, Pennsylvania, USA. Electronic address:

In the last few decades, neurobiological and human brain imaging research have greatly advanced our understanding of brain mechanisms that support perception and memory, as well as their function in daily activities. Knowledge of the neurobiological mechanisms behind the deafferentation of stomatognathic systems has also expanded greatly in recent decades. In particular, current studies reveal that the peripheral deafferentations of stomatognathic systems may be projected globally into the central nervous system (CNS) and become an associated critical factor in triggering and aggravating neurodegenerative diseases.
