Nerve Blocks: Part II. Lower Extremity.

Am Fam Physician 2020 06;101(11):669-679

Uniformed Services University of the Health Sciences, Bethesda, MD, USA.

Family physicians use anesthesia to provide diagnostic and procedural analgesia for conditions such as neuropathies, fracture reduction, foreign body removals, and complex wound management. Local infiltration of anesthetics is commonly used in this setting because of the ease of use, safety, and effectiveness of the procedure. Nerve blocks are a specific regional anesthesia technique that blocks nerve function distal to the injection site. Read More

Pmp22 super-enhancer deletion causes tomacula formation and conduction block in peripheral nerves.

Hum Mol Genet 2020 06;29(10):1689-1699

Waisman Center, University of Wisconsin-Madison, Madison, WI 53705, USA.

Copy number variation of the peripheral nerve myelin gene Peripheral Myelin Protein 22 (PMP22) causes multiple forms of inherited peripheral neuropathy. The duplication of a 1.4 Mb segment surrounding this gene in chromosome 17p12 (c17p12) causes the most common form of Charcot-Marie-Tooth disease type 1A, whereas the reciprocal deletion of this gene causes a separate neuropathy termed hereditary neuropathy with liability to pressure palsies (HNPP).

An Anatomic and Clinical Study of the Innervation of the Dorsal Midfoot Capsule.

Foot Ankle Int 2019 Oct 23;40(10):1209-1213. Epub 2019 Jul 23.

Department of Orthopedic Surgery, Medical College of Wisconsin, Milwaukee, WI, USA.

Background: Dorsal pain from osteoarthritic midfoot joints is thought to be relayed by branches of the medial and lateral plantar, sural, saphenous, and deep peroneal nerves (DPN). However, there is no consensus on the actual number or pathways of the nervous branches for midfoot joint capsular innervation. This study examined the DPN's terminal branches at the midfoot joint capsules through anatomic dissection and confirmation of their significance in a clinical case series of patients with midfoot pain relief after DPN block.

Ultrasound-guided ankle block. History revisited.

Best Pract Res Clin Anaesthesiol 2019 Mar 7;33(1):79-93. Epub 2019 May 7.

Department of Anaesthesiology, University Hospitals of the KU Leuven, Herestraat 49, 3000, Leuven, Belgium.

Following forefoot surgery, compared to the traditional multimodal approach, regional anesthesia and analgesia provides high quality pain relief, decreases opioids consumption and leads to very high satisfaction scores. Traditional regional techniques relied either on wound infiltration, landmark technique ankle blocks or popliteal sciatic nerve block. Numerous anatomic variations of the different nerves might lead to failure following a blind technique. Read More

Randomized Controlled Trial of Physical Exercise in Diabetic Veterans With Length-Dependent Distal Symmetric Polyneuropathy.

Front Neurosci 2019 11;13:51. Epub 2019 Feb 11.

Research Service, Department of Veterans Affairs, Edward Hines Jr. VA Hospital, Hines, IL, United States.

Physical exercise is an essential adjunct to the management of patients with type 2 diabetes mellitus. Therapeutic interventions that improve blood flow to peripheral nerves, such as exercise, may slow the progression of neuropathy in the diabetic patient. This randomized clinical trial was conducted to determine whether a structured program of aerobic, isokinetic strength, or the combination of aerobic-isokinetic strength exercise intervention alters peripheral nerve function in glycemic-controlled diabetic patients with advanced length-dependent distal symmetric polyneuropathy.

'SCALD-ED' Block: Superficial Cutaneous Anesthesia in a Lateral Leg Distribution within the Emergency Department - A Case Series.

J Emerg Med 2019 Mar 9;56(3):282-287. Epub 2019 Jan 9.

Department of Emergency Medicine, Rutgers New Jersey Medical School, Newark, New Jersey.

Background: In the midst of a nationwide opioid epidemic, focus has been placed on identifying and utilizing safe, effective opioid-free analgesic alternatives. Lower-extremity peripheral nerve blockades are common and often involve both motor and sensory anesthesia, resulting in leg weakness and ambulatory difficulty. The aim of this case report is to describe an ultrasound-guided peripheral nerve block technique (superficial cutaneous anesthesia in a lateral (leg) distribution within the emergency department ['SCALD-ED' block]) that provides motor-sparing, purely sensory anesthesia after a superficial injury to the lateral leg in patients presenting to the emergency department.

Anti-neurofascin autoantibody and demyelination.

Neurochem Int 2019 11 22;130:104360. Epub 2018 Dec 22.

Department of Neurology, Neurological Institute, Graduate School of Medical Sciences, Kyushu University, 3-1-1 Maidashi, Higashi-ku, Fukuoka, 812-8582, Japan.

Demyelination diseases involving the central and peripheral nervous systems are etiologically heterogeneous with both cell-mediated and humoral immunities playing pathogenic roles. Recently, autoantibodies against nodal and paranodal proteins, such as neurofascin186 (NF186), neurofascin155 (NF155), contactin-1 (CNTN1), contactin-associated protein 1 (CASPR1) and gliomedin, have been discovered in not only chronic demyelinating conditions, such as multiple sclerosis (MS) and chronic inflammatory demyelinating polyradiculoneuropathy, but also in acute demyelinating conditions, such as Guillain-Barré syndrome. Only a minority of these patients harbor anti-nodal/paranodal protein antibodies; however, these autoantibodies, especially IgG4 subclass autoantibodies to paranodal proteins, are associated with unique features and these conditions are collectively termed nodopathy or paranodopathy.

J Peripher Nerv Syst 2018 Jun 8;23(2):88-98. Epub 2018 May 8.

Department of Molecular Medicine, Bakirkoy Dr. Sadi Konuk Research and Training Hospital, Istanbul, Turkey.

Tangier disease (TD) (OMIM#205400) is a rare cause of inherited metabolic neuropathies characterized by marked deficiency of high-density lipoproteins and accumulation of cholesterol esters in various tissue resulting from reverse cholesterol transport deficiency. We report a case of a patient with TD with multifocal demyelinating neuropathy with conduction block who presents with winging scapula, tongue, and asymmetric extremity weakness.

Dexmedetomidine Added to Local Anesthetic Mixture of Lidocaine and Ropivacaine Enhances Onset and Prolongs Duration of a Popliteal Approach to Sciatic Nerve Blockade.

Clin Ther 2017 Jan 10;39(1):89-97.e1. Epub 2016 Dec 10.

Department of Anaesthesiology, First Affiliated Hospital, Wenzhou Medical University, Zhejiang, China. Electronic address:

Purpose: A literature review of multiple clinical studies on mixing additives to improve pharmacologic limitation of local anesthetics during peripheral nerve blockade revealed inconsistency in success rates and various adverse effects. Animal research on dexmedetomidine as an adjuvant on the other hand has promising results, with evidence of minimum unwanted results. This randomized, double-blinded, contrastable observational study examined the efficacy of adding dexmedetomidine to a mixture of lidocaine plus ropivacaine during popliteal sciatic nerve blockade (PSNB).

University of California San Francisco School of Medicine, San Francisco, CA, USA.

Neurological injuries following peripheral nerve blocks are a relatively rare yet potentially devastating complication depending on the type of lesion, affected extremity, and duration of symptoms. Medical management continues to be the treatment modality of choice with multimodal nonopioid analgesics as the cornerstone of this therapy. We report the case of a 28-year-old man who developed a clinical common peroneal and lateral sural cutaneous neuropathy following an uncomplicated popliteal sciatic nerve block. Read More

Contribution of the sural nerve to postural stability and cutaneous sensation of the lower limb.

Foot Ankle Int 2015 Apr 19;36(4):450-6. Epub 2014 Dec 19.

Department of Podiatry, Faculty of Health Sciences, La Trobe University, Bundoora, Victoria, Australia

Background: The sural nerve is a cutaneous nerve of the lower limb that innervates the posterolateral aspect of the lower leg, ankle, and foot. Considering this pattern, it is plausible that it contributes to the maintenance of postural stability. However, the implications of sensory loss following sural nerve injury have yet to be thoroughly investigated. Read More
