Abstract
Background The use of corticosteroids has become a part of the standard of care in various pathologies but their use in peripheral nerve injury treatment is limited. Given corticosteroids' anti-inflammatory properties and their regulatory role in neuronal protein production and myelination, corticosteroids could serve as an adjunct therapy for peripheral nerve injuries. This review aims to systematically investigate the current use of corticosteroid treatment in peripheral nerve pathologies. Methods The systematic search was performed on PubMed, MEDLINE, EMBASE, Scopus, Cochrane, and Web of Science using keywords such as "corticosteroid treatment," "peripheral nerve damage," "peripheral neuropathy," and "complications." The PRISMA guidelines were used to conduct the systematic review and all articles were reviewed by the corresponding author. After the initial search, individual study titles and abstracts were further screened and categorized using an inclusion and exclusion criteria followed by a final full-text review. Results Out of the total 27,922 identified records, 203 studies were included based on the selection criteria. These studies focused on the use and efficacy of steroids across a spectrum of compression and non-compression peripheral neuropathies such as cubital tunnel syndrome and chronic inflammatory demyelinating polyradiculoneuropathy. Various studies noted the promising role of steroids in offering pain relief, nerve block, and nerve regeneration effects. Additionally, safety considerations and potential complications regarding steroid use in peripheral nerve injuries were analyzed. Conclusion While there is currently limited clinical utilization of corticosteroids in peripheral nerve pathologies, the anti-inflammatory and regenerative effects that steroids provide may be a beneficial tool in managing various peripheral neuropathies and their associated pain. Additional clinical trials and investigation into the mechanism of action could improve the reputation of steroid use as peripheral nerve injury treatment.

Abstract
Meralgia paresthetica (MP) is a painful condition caused by damage or constriction of the lateral femoral cutaneous nerve (LFCN). This entrapment condition typically arises due to various factors, including trauma, pelvic tumors, external compression from belts or snug attire, and weight gain. The prognosis is generally favorable since most cases are self-limiting or respond to conservative treatment. We present the case of a 53-year-old overweight man, with no relevant medical history, who was a victim of a traffic accident in October 2023 which resulted in polytrauma, according to the Case Reports (CARE) checklist. The main complaint of the patient was tingling of the left thigh, with dysesthesia to gentle rubbing along the anterolateral surface. After a diagnostic study, a diagnosis of post-trauma MP was thus established, probably due to seat-belt compression of the LFCN, and physiatric treatment was initiated. With the assistance of ultrasound, a large hematoma was seen, above the inguinal ligament with drainage of 140ccc of serosanguineous fluid with resolution of the symptoms. This case emphasizes the importance of a physiatry consultation for a correct diagnosis and focuses on the main complaint of a polytrauma patient.

Abstract
BACKGROUND Pain and sensory disturbance in the distribution of the lateral femoral cutaneous nerve in the ventrolateral portion of the thigh is called meralgia paresthetica (MP). The incidence of MP has risen along with the increasing prevalence of obesity and diabetes mellitus and was recently estimated at 32 new cases per 100 000 persons per year. In this review, we provide an overview of current standards and developments in the diagnosis and treatment of MP. METHODS This review is based on publications retrieved by a selective literature search, with special attention to meta-analyses, systematic reviews, randomized and controlled trials (RCTs), and prospective observational studies. RESULTS The diagnosis is mainly based on typical symptoms combined with a positive response to an infiltration procedure. In atypical cases, electrophysiological testing, neurosonography, and magnetic resonance imaging can be helpful in establishing the diagnosis. The literature search did not reveal any studies of high quality. Four prospective observational studies with small case numbers and partly inconsistent results are available. In a meta-analysis of 149 cases, pain relief was described after infiltration in 85% of cases and after surgery in 80%, with 1-38 months of follow-up. In another meta-analysis of 670 cases, there was pain relief after infiltration in 22% of cases, after surgical decompression in 63%, and after neurectomy in 85%. Hardly any data are available on more recent treatment options, such as radiofrequency therapy, spinal cord stimulation, or peripheral nerve stimulation. CONCLUSION The state of the evidence is limited in both quantity and quality, corresponding to evidence level 2a for surgical and non-surgical methods. Advances in imaging and neurophysiological testing have made the diagnosis easier to establish. When intervention is needed, good success rates have been achieved with surgery (decompression, neurectomy), and variable success rates with infiltration.

Abstract
Purpose of Review Meralgia paresthetica (MP) is a condition characterized by paresthesias, neuropathic pain, and alterations in sensorium of the anterolateral thigh secondary to impingement of the lateral femoral cutaneous nerve (LFCN). MP is generally diagnosed by clinical history and is often a diagnosis of exclusion. When diagnosis remains a challenge, diagnostic modalities such as ultrasound, MRI, electromyography, and nerve conduction studies have been utilized as an adjunct. This review summarizes the most recent medical literature regarding MP, its pathophysiology, presentation, and current treatment options. Recent Findings Treatment options for patients with MP range from lifestyle modifications and conservative management to surgical procedures. Initial management is often conservative with symptoms managed with medications. When conservative management fails, the next step is regional blocks followed by surgical management. The conflicting data for treatment options for MP highlight how the evidence available does not point to a single approach that's universally effective for treating all patients with MP. Summary Despite the apparent success at treating MP with regional blocks and surgical interventions, much remains to be known about the dosing, frequency, and optimal interventions due to the inconclusive results of current studies. Further research including randomized controlled trials are needed to better understand the most optimal treatment options for MP including studies with a larger number of participants.

Abstract
The prevalence of meralgia paresthetica (MP), which is caused by compression of the lateral femoral cutaneous nerve (LFCN), has been increasing over recent decades. Since guidelines and large-scale studies are lacking, there are substantial regional differences in diagnostics and management in MP care. Our study aims to report on current diagnostic and therapeutic strategies as well as time trends in clinical MP management in Germany. Patients hospitalized in Germany between January 1, 2005, and December 31, 2018, with MP as their primary diagnosis were identified using the International Classification of Disease (ICD-10) code G57.1 and standardized operations and procedures codes (OPS). A total of 5828 patients with MP were included. The rate of imaging studies increased from 44% in 2005 to 79% in 2018 (p < 0.001) and that of non-imaging diagnostic studies from 70 to 93% (p < 0.001). Among non-imaging diagnostics, the rates of evoked potentials and neurography increased from 20%/16% in 2005 to 36%/23% in 2018 (p < 0.001, respectively). Rates of surgical procedures for MP decreased from 53 to 37% (p < 0.001), while rates of non-surgical procedures increased from 23 to 30% (p < 0.001). The most frequent surgical interventions were decompressive procedures at a mean annual rate of 29% (± 5) throughout the study period, compared to a mean annual rate of 5% (± 2) for nerve transection procedures. Between 2005 and 2018, in-hospital MP care in Germany underwent significant changes. The rates of imaging, evoked potentials, neurography, and non-surgical management increased. The decompression of the LFCN was substantially more frequent than that of the LFCN transection, yet both types of intervention showed a substantial decrease in in-hospital prevalence over time.

Abstract
OBJECTIVE Meralgia paresthetica is a common condition that is usually diagnosed by its classical clinical presentation and by exclusion of a spinal origin of pain, sensory loss, and/or paresthesias in the anterolateral thigh. Treatment modalities include conservative management, local injections, and surgical therapy. To date, no level 1 evidence exists about treatment options for idiopathic meralgia paresthetica. This review article aims to give a structured overview of epidemiology, history, anatomy, diagnostics, and treatment. It focuses on the existing literature and current developments in clinical management. METHODS A literature search on PubMed/MEDLINE was performed on 20 December 2021, yielding 1412 results. Abstracts were screened and classified in terms of epidemiology, anatomy, diagnostics, and treatment. RESULTS High-quality observational data that was included in recent meta-analyses showed satisfactory results for conservative management, injections, and surgical decompression or neurectomy, but there is some major methodological criticism. For idiopathic meralgia paresthetica, the results of surgical decompression have never been compared to those of neurectomy in a randomized setup. The only study protocol published so far does not consider any extended decompression techniques (dynamic, circumferent, proximal, and distal to the inguinal ligament). A multicenter, prospective design has never been proposed. DISCUSSION Reliable high-quality evidence on the treatment of idiopathic meralgia paresthetica is lacking at the current state, and challenges in clinical decision-making remain.

Abstract
PURPOSE OF REVIEW This review article summaries the epidemiology, etiology, clinical presentations, and latest treatment modalities of meralgia paresthetica, including the latest data about peripheral and spinal cord stimulation therapy. Meralgia paresthetica (MP) causes burning, stinging, or numbness in the anterolateral part of the thigh, usually due to compression of the lateral femoral cutaneous nerve (LFCN). RECENT FINDINGS There are emerging data regarding the benefit of interventional pain procedures, including steroid injection and radiofrequency ablation, and other interventions including spinal cord and peripheral nerve stimulation reserved for refractory cases. The strength of evidence for treatment choices in meralgia paraesthetica is weak. Some observational studies are comparing local injection of corticosteroid versus surgical interventions. However, more extensive studies are needed regarding the long-term benefit of peripheral and spinal cord stimulation therapy.

Abstract
Meralgia paresthetica (MP) is one of the most common mononeuropathies of the lower limb, characterized by injury or compression of the lateral cutaneous femoral nerve at the level of the anterior superior iliac spine and inguinal ligament. Many predisposing factors, such as weight gain, obesity, and restrictive clothing, contribute to the injury of the lateral cutaneous femoral nerve along its course from the pelvis towards the thigh. Although a great number of cases are successfully treated with conservative measures, a subgroup of patients suffer chronic dysesthetic pain with intermittent flare-ups in their lifetime, with a negative impact on quality of life, requiring additional treatment. The purpose of this case report is to describe the successful management of MP with ultrasound-guided pulsed radiofrequency of the lateral cutaneous femoral nerve.

Abstract
Meralgia paresthetica, a condition characterized by tingling, numbness, and burning pain in the lateral aspect of the thigh, is caused by compression of the lateral femoral cutaneous nerve. The incidence of meralgia paresthetica increases with obesity and diabetes. The unique anatomy of the nerve that tunnels through the inguinal ligament predisposes it to inflammation, trauma, and entrapment. The pathology of meralgia paresthetica parallels that of entrapment neuropathies but with additional inflammatory overlay in certain instances. The clinical diagnosis is relatively simple due to its unique clinical features. The prognosis is generally excellent, and the treatment is straightforward that includes peripheral nerve blocks, neurectomy, nerve decompression, and pulsed radiofrequency neuromodulation. This current case of meralgia paresthetica highlights the salient clinical symptoms and signs. We have also described the electrophysiological studies of the lateral femoral cutaneous nerve, its anatomical variations, and the associations of meralgia paresthetica with bariatric surgery, critical care patients, tight clothing, pregnancy, and posterior spine surgery. We have also outlined the current treatment strategies.

Abstract
Importance Carpal tunnel syndrome and meralgia paresthetica are 2 common neuropathies complicating pregnancy. Each of these causes significant discomfort but can be diagnosed and treated safely during pregnancy. Objective This article outlines the existing literature diagnosis, treatment, and prognosis of carpal tunnel syndrome and meralgia paresthetica, specifically looking at the implications during pregnancy. The aim is to provide a reference for physicians diagnosing and treating neuropathies in pregnant patients. Evidence Acquisition Existing literature on neuropathies during pregnancy, clinical presentation, and treatment options for both carpal tunnel syndrome and meralgia paresthetica was reviewed through a MEDLINE and PubMed search. Referenced articles were reviewed and used as primary source materials as appropriate. Results Carpal tunnel syndrome affects individuals of all ages and sexes but is more prevalent in women, particularly during pregnancy. Meralgia paresthetica can occur in various circumstances but is most commonly associated with prolonged second stage in lithotomy position. Multiple clinical signs and neurologic tests are useful to establish the diagnosis of either neuropathy. Effective treatment for carpal tunnel syndrome includes wrist splints, steroid and lidocaine injections, and release surgery. Optimal treatment of meralgia paresthetica remains controversial but includes nerve block injections and active release techniques. Conclusions and Relevance Neuropathies are common in pregnancy and can result in significant impairment. Accurate diagnosis is possible during pregnancy and can usually be accomplished with bedside neurologic tests. Treatment options can be safely considered during pregnancy and can result in symptomatic improvement and reduction in chronic symptoms.

Abstract
AbstractMeralgia paresthetica (MP), also known as Bernhardt–Roth syndrome, is a peripheral neuropathy of the primary sensory lateral femoral cutaneous nerve (LFCN). Its diagnosis is challenging, because it can mimic other clinical conditions particularly associated with upper lumbar spine or pelvis. Patients present with pain and paresthesia over the anterolateral thigh. Diagnosis is usually based on clinical examination and is supported by sensory nerve conduction (SNC) studies. The initial treatment is always conservative. In limited number of patients who are refractory to conservative managements, surgical treatment via decompression/neurolysis or neurectomy is concerned. There is still no consensus on which surgical technique is the best and the first choice. We retrospectively analyzed the surgical outcomes of 12 nonobese patients who underwent decompression/neurolysis between the years 2013 and 2018. Bilateral SNC studies were performed in all cases which supported the diagnosis. We applied conservative treatments for 3 months in addition to the treatments previously applied in other centers. Surgery was recommended for the patients who were refractory to these treatments. Preoperative and postoperative pain levels during follow-up visits were evaluated with visual analogue scale (VAS). A retrospective analysis was performed on preoperative and postoperative 6th month VAS scores. The mean preoperative VAS value was 8.75 ± 0.62 and the postoperative VAS value at the sixth month was 1.17 ± 0.72. A significant reduction in the pain was shown (p < 0.05). Our surgical results showed that decompression/neurolysis of the LFCN should be concerned as the primary surgical approach to avoid negative outcomes of resection surgeries.

Abstract
BACKGROUND Meralgia paresthetica is a mononeuropathy of the lateral femoral cutaneous nerve. A common therapy is injection with corticosteroids. The goal of this study was to analyze the effect of injection with methylprednisolone/lidocaine vs placebo. METHODS After randomization, 10 patients received a nerve stimulator-guided injection with methylprednisolone/lidocaine, and 10 patients received saline. The primary outcome measure was pain (visual analogue scale, VAS). RESULTS In the placebo group, there was a significant pain reduction (baseline VAS, 6.8; VAS week 12, 4.3; P = .014). The VAS score in the methylprednisolone group did not show a significant reduction (baseline VAS, 7.4; VAS week 12, 4.8; P = .053). There was no significant difference in pain reduction between the groups. CONCLUSIONS We found no objective evidence for benefit from nerve stimulator-guided injection with corticosteroids in meralgia paresthetica, although this study is limited by a small sample size. Future placebo-controlled studies using ultrasound-guided injection are warranted.

Abstract
Introduction: Meralgia paresthetica (MP) is a painful mononeuropathy of the lateral femoral cutaneous nerve. It is usually idiopathic and can be treated with drugs used for neuropathic pain such as pregabalin, gabapentin, and amitriptyline. Objectives: This study was done to study the effect of triamcinolone acetonide on drug refractory MP. Methods: This study was a retrospective case file review. Results: Eight patients were treated with local injections of triamcinolone. The patients were followed up for a period of 4 months to 54 months. There was significant symptomatic improvement with six patients having complete improvement and all patients reporting >50% improvement. Patients who had recurrence of symptoms on follow up received up to four injections as per their requirement and repeated injections also produced >50% symptom relief. Conclusion: Triamcinolone acetonide injected locally seems to be an effective and safe treatment for refractory MP. A randomized control trial has been planned to look for efficacy and safety.

Abstract
Meralgia paresthetica is a non-life-threatening neurological disorder characterized by numbness, tingling, and burning pain over the anterolateral thigh due to impingement of the lateral femoral cutaneous nerve. This disorder has been seen in patients with diabetes mellitus and obesity, but has also been observed in patients after procedures such as posterior spine surgery, iliac crest bone grafts, lumbar disk surgery, hernia repair, appendectomies, and pelvic osteotomies that ultimately lead to compression or damage to the lateral femoral cutaneous nerve. Overall, permanent sequelae of meralgia paresthetica are rare, however, some cases do require intervention.

Evaluating the evidence: is neurolysis or neurectomy a better treatment for meralgia paresthetica? Acta Neurochir (Wien) 2017; 159:931-936. [PMID: 28283866 DOI: 10.1007/s00701-017-3136-x] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2016] [Accepted: 02/22/2017] [Indexed: 10/20/2022]
Abstract
BACKGROUND Meralgia paresthetica is a mononeuropathy of the lateral femoral cutaneous nerve (LCFN). Surgical treatment involves transection or decompression of the LCFN. There is no clear consensus on the superiority of one technique over the other. We performed a systematic review of the literature to answer this question. METHODS Eligible studies included those that compared neurolysis versus neurectomy for the treatment of meralgia paresthetica after failure of conservative therapy. Our outcome of interest was resolution of symptoms. We performed a computerized search of MEDLINE (PubMed; all years) and of the Cochrane Central Register of Controlled Trials. Eligible studies had to include the words "meralgia paresthetica" and "surgery." All patients regardless of age were included, and there was no language restriction. We then reviewed the articles' titles and abstracts. All studies that compared neurolysis to neurectomy were included in the analysis. RESULTS Of the studies identified, none were randomized controlled trials. There were two German language articles that were translated by a third researcher. Each study was evaluated by two independent researchers who assigned a level of evidence according to American Association of Neurologist algorithm and also performed data extraction (neurolysis vs. neurectomy and resolution of pain symptoms). Each study was found to be level four evidence. CONCLUSION After reviewing the data, there was insufficient evidence to recommended one method of treatment over the other. This highlights the importance of keeping a national registry in order to compare outcomes between the two methods of treatment.

Abstract
STUDY DESIGN Prospective study of consecutive patients. OBJECTIVE The purpose of the study was to evaluate the incidence, risk factors, and time to resolution of lateral femoral cutaneous nerve palsy (LFCNP) after posterior spinal fusion (PSF) for adolescent idiopathic scoliosis (AIS). SUMMARY OF BACKGROUND DATA No prior studies have prospectively evaluated the prevalence of LFCNP exclusively in the treatment of AIS. METHODS Between June 2014 and May 2015, patients undergoing PSF for AIS were examined preoperatively, postoperatively, and at follow-up clinic visits until the resolution of the LFCNP. All neurologic examinations were performed by attending pediatric orthopedic surgeons. Patients who underwent staged, revision or anterior procedures, had preoperative neurologic deficits or neuropathy, were excluded. RESULTS A total of 55 patients with an average age of 14 years (10-21) were enrolled. Twenty-five percent (14/55) of patients had a postoperative LFCNP. There were no other postoperative neurologic deficits. Of the 14 patients with an LFCNP, 57% of these were bilateral. Fourteen percent (2/14) of these patients had absent sensation to light touch, whereas 85% (12/14) had decreased sensation. No patients reported experiencing pain associated with the LFCNP or tenderness when the anterolateral thigh was palpated. The LFCNP did not limit postoperative mobilization or prolong hospital stay. The LFCNP was noted to resolve in an average of 3.6 days (1-18); 6/14 (43%) resolved after 1 day. No correlation was observed between occurrence of LFCNP and sex, age, height, body mass index, length of fusion, Cobb angle, or blood loss. The occurrence of LFCNP was associated with heavier weight (P = 0.032) and longer operative times (P = 0.016). Resolution of the LFCNP was associated with longer operative time (P = 0.010). CONCLUSION LFCNP occurred in 25% of AIS patients undergoing PSF. Risk of LFCNP increased with longer operative times and heavier patient weight. On average, LFCNP resolved in less than 4 days and did not cause any pain or limitations. LEVEL OF EVIDENCE 2.

Abstract
Intraoperative peripheral nerve injury during colorectal surgery procedures is a potentially serious complication that is often underestimated. The Trendelenburg position, use of inappropriately padded armboards and excessive shoulder abduction may encourage the development of brachial plexopathy during laparoscopic procedures. In open colorectal surgery, nerve injuries are less common. It usually involves the femoral plexus associated with lithotomy position and self-retaining retractor systems. Although in most cases the recovery is mostly complete, treatment consists of physical therapy to prevent muscular atrophy, protection of hypoesthesic skin areas and analgesics for neuropathic pain. The aim of the present study is to review the incidence, prevention and management of intraoperative peripheral nerve injury.

Abstract
Although simple characterization of discomfort as cramps, heaviness, shooting pains, and so forth can be misleading, history and examination are key to accurate diagnosis. Absence of both dorsalis pedis and posterior tibial pulses strongly suggests peripheral arterial disease (PAD), and the presence of either pulse makes PAD less likely. Hydroxymethylglutaryl coenzyme A reductase inhibitors (statins) are a common cause of lower extremity myalgias. Restless legs syndrome causes nocturnal discomfort but must be distinguished from confounding“mimics." Neurologic causes of leg symptoms include lumbar spinal stenosis, radiculopathy, distal symmetric polyneuropathy, and entrapment neuropathy. Many common causes of leg discomfort can be managed conservatively.

Abstract
Meralgia paresthetica is a mononeuropathy of the femoral cutaneous nerve with characteristic findings, usually secondary to injury or compression, being most common in the inguinal area. Exceptional cases associated with compressions caused by abdominal or pelvic tumors have been published, so it is always advisable to extend the study with imaging tests. We present a case associated with a renal tumor.

Abstract
BACKGROUND Meralgia paraesthetica is a clinical syndrome for which a number of treatments are in common use, including conservative measures, injection of corticosteroid with local anaesthetic and surgery. We aimed to examine the evidence for the relative efficacy of these interventions. This review was first published in 2008. Searches were updated in 2010 and 2012. OBJECTIVES To assess the relative efficacy of commonly used treatments for meralgia paraesthetica. SEARCH METHODS We searched the Cochrane Neuromuscular Disease Group Specialized Register (1 October 2012), CENTRAL (2012, issue 9 in The Cochrane Library), MEDLINE (January 1966 to October 2012), EMBASE (January 1980 to October 2012) and CINAHL Plus (January 1937 to October 2012) for randomised controlled studies. Non-randomised studies were identified by searching MEDLINE (January 1966 to October 2012) and EMBASE (January 1980 to October 2012). We also inspected the reference lists of these studies. SELECTION CRITERIA We were unable to identify any randomised controlled trials (RCTs) or quasi-RCTs. We therefore looked for high quality observational studies meeting the following criteria: (1) At least five cases of meralgia paraesthetica. (2) Follow-up of at least three months after intervention (if any). (3) At least 80% of cases followed up. DATA COLLECTION AND ANALYSIS Three authors independently extracted relevant data from each study meeting the selection criteria and transferred into a data extraction form. MAIN RESULTS We found no RCTs or quasi-RCTs in the original review or updates in 20011 and 2012. Cure or improvement have been described in high quality observational studies: (1) A single study describes spontaneous improvement of meralgia paraesthetica in 20 (69%) of 29 cases. (2) Four studies evaluating the injection of corticosteroid and local anaesthetic found cure or improvement in 130 (83%) out of a combined total of 157 cases. (3) Surgical treatments have been found to be beneficial in 264 (88%) out of 300 cases treated with decompression (nine studies); and 45 (94%) out of 48 cases treated with neurectomy (three studies). (4) Ninety-nine (97%) out of 102 patients with iatrogenic meralgia paraesthetica recovered completely (three studies). AUTHORS' CONCLUSIONS In the absence of any published RCTs or quasi-RCTs, the objective evidence base for treatment choices in meralgia paraesthetica is weak. High quality observational studies report comparable high improvement rates for meralgia paraesthetica following local injection of corticosteroid and surgical interventions (either nerve decompression or neurectomy). However, a similar outcome has been reported without any intervention in a single natural history study.

Abstract
Meralgia paresthetica is a mononeuropathy affecting the lateral femoral cutaneous nerve that is extremely rare in children. Two adolescent females, aged 11 and 13 years, presented due to tingling and pain on the side of the thigh of 2 to 3 weeks duration. The general examination revealed mild obesity; the neurological examination of both patients is normal except for pain, hypo- or hyperesthesia on the side of the quadriceps. An electromyogram was performed in the first case that reveals decreased conduction velocity of the affected lateral femoral cutaneous nerve. The younger child was treated successfully with diet and topiramate; the second patient's symptoms disappeared after initiating conservative measures. Meralgia paresthetica is probably underdiagnosed in the pediatric population. First-line treatment should be conservative, but topiramate may be useful for the treatment of meralgia paresthetica, although broader studies are needed to evaluate its true effectiveness in this pathological condition.
