RESUMEN
Anterior, lateral, and posterior cutaneous nerve entrapment syndromes have been proposed as etiologies of trunk pain. However, while these syndromes are analogous, comprehensive reports contrasting the three subtypes are lacking. We therefore reviewed the literature on anterior, lateral, and posterior cutaneous nerve entrapment syndrome. We searched the PubMed and Cochrane Library databases twice for relevant articles published between March and September 2022. In addition to 16 letters, technical reports, and review articles, a further 62, 6, and 3 articles concerning anterior, lateral, and posterior cutaneous nerve entrapment syndromes, respectively, were included. These syndromes are usually diagnosed based solely on unique history and examination findings; however, the diagnostic process may be prolonged, and multiple re-evaluations are required. The most common first-line treatment is trigger point injection; however, the management of refractory cases remains unclear. Awareness of this disease should be expanded to medical departments other than general medicine.

INTRODUCTION: Kettlebell snatches are an efficient and effective exercise. If the kettlebell being utilized is too heavy or too many repetitions are executed, this can lead to an overuse injury such as a tendinopathy. Multiple orthopedic tests exist to evaluate for a distal biceps tendon rupture. At present, there are no publications utilizing shockwave and active rehabilitation to treat distal bicipital tendinopathy with Lateral Antebrachial Cutaneous Nerve (LABCN) entrapment. Currently, no published manuscripts are reporting distal bicipital tendinopathy with LABCN nerve entrapment being treated successfully with shockwave and active rehabilitation over the course of 5 weeks. METHODS: The objective of this case report is to examine the conservative management of a 37-year-old male with a diagnosis of distal bicipital tendinopathy and LABCN entrapment. The patient presents with discomfort originated weeks prior after an intense block of kettlebell training. The patient was diagnosed with brachioradialis tendinopathy due to the specifics of his injury. Following the initial evaluation, the patient was unable to supinate the forearm past 45° actively, yet he can passively achieve 90°, although this is done with minor discomfort. DISCUSSION: The patient's rehab began with the execution of wrist, elbow, and shoulder controlled articular rotation (CARS). The concept of CARs is to train the joint and soft tissues to respond to full range activity. A progressive approach utilizing isometric to eccentric exercise with extracorporeal shockwave was used. The authors studied forty-eight patients with chronic distal biceps tendinopathy. After five shockwave therapy treatments over three months, there was a significant decrease in symptomology without complications (Furia et al., 2017). CONCLUSION: This case report demonstrates that active rehabilitation and shockwave therapy effectively resolved the patient's symptoms with no adverse reactions. Additionally, the case report can be a suggested management protocol for successful conservative management for patients with suspected distal bicipital tendinopathy with LABCN entrapment going forward.

INTRODUCTION: Superior cluneal nerve (SCN) entrapment giving rise to low back pain (LBP) remains undiagnosed many times; in this clinical study authors have evaluated therapeutic role of lidocaine injection of SCN for low back pain relief in patients with SCN entrapment. METHODS: The present study was a prospective, observational study; 25 patients with unilateral LBP over the iliac crest and buttock for more than six months not responding to conservative measures were included in this clinical trial. SCN lidocaine injection was done under fluoroscopy guidance; patients having more than 50% reduction in numeric rating scale (NRS) score, for at least 2 h following SCN injection, were enrolled in the study and followed for 6 months. The primary outcome measure was severity of LBP, measured by NRS score. Secondary outcome measures were percentage pain relief; Oswestry Disability Index (ODI) score, reduction of analgesic usage, DSM-IV score for psychological assessment. All these assessments were done prior to the procedure and at 2 weeks, 1, 3 and 6 months after the procedure. RESULTS: A significant reduction in the NRS scores was observed at 2 weeks, 1, 3 and 6 months after SCN lidocaine injection as compared to the baseline (P value < 0.05); authors also observed a significant pain relief and significantly reduced ODI scores, analgesic consumption and DSM scores compared to the baseline values (P value < 0.05). CONCLUSION: A single SCN lidocaine injection provided significant pain relief in LBP patients with SCN entrapment for a period of 6 months.

Anterior cutaneous nerve entrapment syndrome (ACNES) is often overlooked in the differential diagnosis of chronic abdominal pain (CAP). An 11-year-old boy with CAP previously studied in emergency and digestive services without detecting organic pa-thology, suggesting a psychosomatic origin. On examination, he showed pain in the abdominal wall located to the area of the terminal branch of the Th11 intercostal nerve, with a positive Carnett's sign and a favorable response to injection with local anesthetic at the trigger point. Somatosensory evoked potentials revealed right anterior rectus nerve neuropathy. He was diagnosed with ACNES. As treatment, an ultrasound-guided subfascial injection with lidocaine and dexame-thasone into the trigger point was administered. After four months, he remains asymptomatic. For the treatment of ACNES in pediatrics patients, a step-up strategy should be applied, starting with trigger point in-jections of lidocaine and dexamethasone and reserving anterior neurectomy for those cases with limited effect of these injections.

A 71-year-old man, living with metastatic castrate-resistant prostate cancer to the lymph nodes, spine and skull, presented with acute on chronic left eye vision loss. Examination revealed no-light-perception vision, a relative afferent pupillary defect and optic disc cupping. MRI brain revealed optic canal narrowing from metastatic sphenoid bone expansion and extraosseous tumour compressing the intracanalicular optic nerve. The optic disc cupping and excavation without significant pallor of the remaining neuroretinal rim was likely secondary to chronic compression of the optic nerve. The patient was treated with radiation therapy, but did not regain vision and was referred to palliative care as his condition continued to worsen. As patients live longer with advanced cancer, there is a greater risk of metastasis to atypical areas of the body including the optic nerve. This case demonstrates the unique combination of optic disc cupping from optic canal metastasis due to prostate cancer.

RATIONALE: Supracondylar process is a rare bony anomaly that can cause neurovascular symptoms. Previous reports on supracondylar process syndrome mostly suspect the condition by physical examination and simple radiograph with little assistance of electrodiagnostic methods and report efficiency of surgical treatment. PATIENTS CONCERNS: A 45-year-old woman working at an assembly line packing boxes presented with tingling pain at her middle and ring fingers that started 2 months ago. She had positive Tinel sign at the medial side of the distal arm. DIAGNOSIS: Electrodiagnostic inching study on median nerve was conducted and the conduction velocity at the segment between 3âcm to 5âcm proximal to the elbow crease was decreased to 27m/s. Following imaging studies revealed supracondylar process at 4.2âcm proximal to the medial epicondyle. She was successfully treated with conservative treatment. INTERVENTIONS: Oral medications including Non-steroidal anti-inflammatory drug and pregabalin were prescribed along with superficial and deep heat modalities. The extent of manual labor was modified. Additionally, self-massage and stretching/nerve-gliding exercises were delivered. OUTCOMES: The symptoms substantially improved and she could sleep without trouble, however, complete resolution was not achieved. After a year, she was nearly symptom-free after changing occupations with only occasional tingling after manual labor of unusual intensity. LESSONS: This case report enlightens the versatility of electrodiagnostic inching study in localizing median neuropathy at the distal arm and the effectiveness of conservative treatment in supracondylar process syndrome.

BACKGROUND: Somatization is regarded as psychological or emotional distress in the form of physical symptoms that are otherwise medically unexplained. CASE PRESENTATION: We report a case of a patient with a somatic symptom disorder (SSD) and depression who was later diagnosed with anterior cutaneous nerve entrapment syndrome (ACNES) when Carnett's test was positive and block anesthesia using trigger point injections dramatically improved the symptom of abdominal pain. CONCLUSION: We concluded that the differentiation of SSDs, such as psychogenic pain, from ACNES is very difficult. Psychiatrists should be aware of this syndrome.

Chronic abdominal wall pain is a common, yet often overlooked, cause of chronic abdominal pain in both the outpatient and inpatient settings. This disorder most commonly affects middle-aged adults and is more prevalent in women than in men. In chronic abdominal wall pain, the pain occurs due to entrapment of the cutaneous branches of the sensory nerves that supply the abdominal wall. Although the diagnosis of chronic abdominal wall pain can be made using patient history, physical examination, and response to a trigger point injection, patients often undergo extensive and exhaustive laboratory, imaging, and procedural work-up before being diagnosed with this condition, given it is often overlooked. Carnett's sign is a specialized physical examination technique that can help support the fact that the abdominal pain originates from the abdominal wall rather than from the abdominal viscera. The mainstay of treatment consists of reassurance, activity modification, over-the-counter analgesic agent, and trigger point injection. In rare cases, treatment with chemical neurolysis or surgical neurectomy may be required.

PURPOSE: To describe the clinical manifestation and the treatment of complex regional pain syndrome type II in childhood. METHODS: Using information on the symptoms, diagnosis, rehabilitation and outcome of a young patient with complex regional pain syndrome type II. RESULTS: A 9-year -old girl had severe pain in the region of the left foot, signs of a common fibular nerve entrapment, hyperalgesia not limited to the distribution of the injured nerve, weakness and temperature asymmetry unknown origin. She consulted few doctor's before she was given the right diagnosis of complex regional pain syndrome type II. Following the diagnosis the treatment started, it included intensive physiotherapy, electrical therapy and also supportive psychological therapy. Half a year later, the patient was free of the daily pain and returned to all physical activity without any restrictions. CONCLUSIONS: The case report illustrates that peripheral nerve compression or injuries specifically, complex regional pain syndrome type II, should be taken into consideration when evaluating children with weakness and pain of the lower or upper limb. Implication of rehabilitation Raising the awareness of complex regional pain syndrome in the childhood is essential for an early diagnosis and appropriate treatment. The treatment options include early and adequate pain management inclusive electrical therapy and physiotherapy. Psychological therapy helps to avoid psychological stress reaction and the disease negative impact on the child's education and sports and the family social life.

Chronic abdominal pain is common in children and adolescents but challenging to diagnose, because practitioners may be concerned about missing serious occult disease. Abdominal wall pain is an often ignored etiology for chronic abdominal pain. Anterior cutaneous nerve entrapment syndrome causes abdominal wall pain but is frequently overlooked. Correctly diagnosing patients with anterior cutaneous nerve entrapment syndrome is important because nerve block interventions are highly successful in the remittance of pain. Here, we present the case of a pediatric patient who received a diagnosis of functional abdominal pain but experienced pain remittance after receiving a trigger-point injection and transverse abdominis plane block.

PURPOSE: The etiology of low back pain (LBP) is complicated and the diagnosis can be difficult. Superior cluneal nerve entrapment neuropathy (SCN-EN) is a known cause of LBP, although the middle cluneal nerve (MCN) can be implicated in the elicitation of LBP. METHODS: A 76-year-old woman with a 4-year history of severe LBP was admitted to our department in a wheelchair. She complained of bilateral LBP that was exacerbated by lumbar movement. Her pain was severe on the right side and she also suffered right leg pain and numbness. Based on palpation and nerve blocking findings we diagnosed SCN-EN and MCN entrapment neuropathy (MCN-EN). RESULTS: Her symptoms improved with repeated SCN and MCN blocking; the MCN block was the more effective and her symptoms improved. As her right-side pain around the MCN -EN with severe trigger pain recurred we performed microscopic right MCN neurolysis under local anesthesia. This led to dramatic improvement of her LBP and leg pain and the numbness improved. At the last follow-up, 7 months after surgery, she did not require pain medication. CONCLUSIONS: The MCN consists of sensory branches from the dorsal rami of S1-S4. It sandwiches the sacral ligament between the posterior superior and inferior iliac spine as it courses over the iliac crest. Its entrapment at this hard orifice can lead to severe LBP with leg symptoms. An MCN block effect is diagnostically useful. Less invasive MCN neurolysis under local anesthesia is effective in patients who fail to respond to observation therapy.

OBJECTIVE: Anterior cutaneous nerve entrapment syndrome (ACNES) is often an overlooked cause of abdominal pain. Data for pediatric patients, especially with regard to the treatment modalities are scarce. The aim of this study was to present a treatment modality of ACNES with combined local subfascial anesthetic and corticosteroid injection in a prospectively collected cohort of pediatric patients. METHODS: This was a prospective observational long-term study that included pediatric patients who were diagnosed with ACNES in a tertiary care pediatric center and who were followed-up for at least 12 months (median: 1.7 y; range: 1 to 2.7 y). All children were treated by ultrasound-guided subfascial injection of 40 mg 1% lidocaine and 4 mg dexamethasone into the rectus abdominis muscle in the place of the most severe pain (trigger point infiltration). RESULTS: The study included 38 children (28, 73.7% female; median age: 15 y). The majority of patients had pain in the lower right abdominal quadrant and were diagnosed in a median of 6 (range: 0.5 to 50) months after symptoms started. Overall, 24 (63%) patients achieved sustained symptom-free remission after a median of 1 (mean: 1.6; range: 1 to 5) trigger point infiltration during the first treatment session. Five (13%) children were surgically treated because of a lack of long-term response. Children who were surgically treated required a higher number of block applications during the first session of treatment, compared with children who were successfully treated conservatively. DISCUSSION: ACNES in children can be successfully treated by a combined local subfascial anesthetic and corticosteroid trigger point infiltration.

BACKGROUND AND AIMS: Chronic abdominal pain may occasionally be due to terminal endings of intercostal nerves (ACNES, abdominal cutaneous nerve entrapment syndrome) that are entrapped in the abdominal wall. Spontaneous neuropathic flank pain may also be caused by involvement of branches of these intercostal nerves. Aim is to describe a series of patients with flank pain due to nerve entrapment and to increase awareness for an unknown condition coined Lateral Cutaneous Nerve Entrapment Syndrome (LACNES). METHODS: Patients possibly having LACNES (constant area of flank tenderness, small point of maximal pain with neuropathic characteristics, locoregional altered skin sensation) presenting between January 2007 and May 2016 received a diagnostic 5-10mL 1% lidocaine injection. Pain levels were recorded using a numerical rating scale (0, no pain to 10, worst possible). A >50% pain reduction was defined as success. Long term effect of injections and alternative therapies were determined using a satisfaction scale (1, very satisfied, no pain - 5, pain worse). RESULTS: 30 patients (21 women, median age 52, range 13-78) were diagnosed with LACNES. Pain following one injection dropped from 6.9±1.4 to 2.4±1.9 (mean, p<0.001) leading to an 83% immediate success rate. Repeated injection therapy was successful in 16 (pain free n=7, pain acceptable, n=9; median 42 months follow-up). The remaining 14 patients received (minimally invasive) surgery (n=5) or other treatments (medication, manual therapy or pulsed radiofrequency, n=9). Overall treatment satisfaction (scale 1 or 2) was attained in 79%. CONCLUSIONS AND IMPLICATIONS: LACNES should be considered in patients with chronic flank pain. Injection therapy is long term effective in more than half of the population.

BACKGROUND: Some patients with chronic abdominal pain suffer from an anterior cutaneous nerve entrapment syndrome (ACNES). This somewhat illusive syndrome is thought to be caused by the entrapment of end branches of the intercostal nerves residing in the abdominal wall. If ACNES is suspected, a local injection of an anesthetic agent may offer relief. If pain is recurrent following multiple-injection therapy, an anterior neurectomy entailing removal of the entrapped nerve endings may be considered. After 1 year, a 70% success rate has been reported. Research on minimally invasive alternative treatments is scarce. Pulsed radiofrequency (PRF) treatment is a relatively new treatment for chronic pain syndromes. An electromagnetic field is applied around the nerve in the hope of leading to pain relief. This randomized controlled trial compares the effect of PRF treatment and neurectomy in patients with ACNES. METHODS: Adult ACNES patients having short-lived success following injections are randomized to PRF or neurectomy. At the 8-week follow-up visit, unsuccessful PRF patients are allowed to cross over to a neurectomy. Primary outcome is pain relief after either therapy. Secondary outcomes include patient satisfaction, quality of life, use of analgesics and unanticipated adverse events. The study is terminated 6 months after receiving the final procedure. DISCUSSION: Since academic literature on minimally invasive techniques is lacking, well-designed trials are needed to optimize results of treatment for ACNES. This is the first large, randomized controlled, proof-of-concept trial comparing two therapy techniques in ACNES patients. The first patient was included in October 2015. The expected trial deadline is December 2017. If effective, PRF may be incorporated into the ACNES treatment algorithm, thus minimizing the number of patients requiring surgery. TRIAL REGISTRATION: Nederlands Trial Register (Dutch Trial Register), NTR5131 ( http://www.trialregister.nl/trialreg/admin/rctview.asp?TC=5131 ). Registered on 15 April 2015.

This is the second of a two-part series addressing symptoms, evaluation, and treatment of load carriage- related paresthesias. Part 1 addressed rucksack palsy and digitalgia paresthetica; here, meralgia paresthetica (MP) is discussed. MP is a mononeuropathy involving the lateral femoral cutaneous nerve (LFCN). MP has been reported in load carriage situations where the LFCN was compressed by rucksack hipbelts, pistol belts, parachute harnesses, and body armor. In the US military, the rate of MP is 6.2 cases/10,000 personyears. Military Servicewomen have higher rates than Servicemen, and rates increase with age, longer loadcarriage distance or duration, and higher body mass index. Patients typically present with pain, itching, and paresthesia on the anterolateral aspect of the thigh. There are no motor impairments or muscle weakness, because the LFCN is entirely sensory. Symptoms may be present on standing and/or walking, and may be relieved by adopting other postures. Clinical tests to evaluate MP include the pelvic compression test, the femoral nerve neurodynamic test, and nerve blocks using lidocaine or procaine. In cases where these clinical tests do not confirm the diagnosis, specialized tests might be considered, including somatosensory evoked potentials, sensory nerve conduction studies, high-resolution ultrasound, and magnetic resonance imaging. Treatment should initially be conservative. Options include identifying and removing the compression if it is external, nonsteroidal inflammatory medication, manual therapy, and/or topical treatment with capsaicin cream. Treatments for intractable cases include injection of corticosteroids or local anesthetics, pulsed radiofrequency, electroacupuncture, and surgery. Military medical care providers may see cases of MP, especially if they are involved with units that perform regular operations involving load carriage.

Study Design Resident's case problem. Background Entrapment neuropathies represent a diagnostic challenge and require a comprehensive understanding of the nerve's path and the anatomical structures that may cause compression of the nerve. This resident's case problem details the evaluation and differential diagnosis process for median nerve entrapment resulting from forceful and repetitive pronation/supination motions. Diagnosis Median nerve compression syndromes include pronator syndrome, anterior interosseous nerve syndrome, and carpal tunnel syndrome. A cluster of clinical special tests were performed to determine the anatomical site of median nerve entrapment. Based on the patient's history and clinical test results, a diagnosis of pronator syndrome was determined. Provocation testing specific to pronator syndrome assisted with further localizing the site of entrapment to the pronator teres muscle, which guided effective management strategies. Discussion This resident's case problem illustrates the importance of detailed anatomical knowledge and a differential diagnostic process when evaluating a patient with signs and symptoms of an entrapment neuropathy of the median nerve. Electrodiagnostic studies are useful in ruling out carpal tunnel and anterior interosseous nerve syndromes, but are often inconclusive in cases of pronator syndrome. Therefore, a diagnosis of pronator syndrome in this case problem was based on a detailed understanding of median nerve anatomy, potential sites of compression, and unique clinical features associated with this condition.

Chronic abdominal wall pain (CAWP) refers to a condition wherein pain originates from the abdominal wall itself rather than the underlying viscera. According to various estimates, 10% to 30% of patients with chronic abdominal pain are eventually diagnosed with CAWP, usually after expensive testing has failed to uncover another etiology. The most common cause of CAWP is anterior cutaneous nerve entrapment syndrome. The diagnosis of CAWP is made using an oft-forgotten physical examination finding known as Carnett's sign, where focal abdominal tenderness is either the same or worsened during contraction of the abdominal musculature. CAWP can be confirmed by response to trigger point injection of local anesthetic. Once diagnosis is made, treatment ranges from conservative management to trigger point injection and in refractory cases, even surgery. This review provides an overview of CAWP, discusses the cost and implications of a missed diagnosis, compares somatic versus visceral innervation, describes the pathophysiology of nerve entrapment, and reviews the evidence behind available treatment modalities.

BACKGROUND: Abdominal cutaneous nerve entrapment syndrome (ACNES) is a frequently overlooked cause of chronic abdominal pain. We aim to outline the current available literature concerning the treatment of patients diagnosed with ACNES. DATA SOURCES: A systematic search in PubMed, EMBASE, CINAHL, and Cochrane databases was performed. Seven studies were included; describing trigger point injection (TPI) or anterior neurectomy as stand-alone procedure, TPI followed by anterior neurectomy as stepwise regimen, and nerve stimulation and phenolization. After TPI, 86% of the patients showed successful response, 76% at long-term follow-up. Two other studies report successful treatment in 50% of patients. In the included trial using anterior neurectomy, 73% vs 18% of the patients demonstrate a successful pain response in the neurectomy and sham group, respectively. Two cohort studies showed that 69% and 61% of the neurectomy group reported to be satisfied at 18 months and 32 months follow-up, respectively. CONCLUSIONS: There is significant pain relief after injections and anterior neurectomy. Awareness of the diagnosis is important. The validity of currently used diagnostic criteria needs to be evaluated in additional studies.

Hereditary neuropathy with liability to pressure palsies (HNPP) is an autosomal-dominant disorder associated with recurrent mononeuropathies following compression or trivial trauma. Reports on sciatic neuropathy as the presenting manifestation of HNPP are very scarce. We report on a 21-year-old previously healthy man who was admitted with sensorimotor deficits in his left leg. He had no history of preceding transient episodes of weakness or sensory loss. Clinical and electrophysiological examinations were consistent with sciatic neuropathy. Cerebrospinal fluid investigation and MRI of the nerve roots, plexus, and sciatic nerve did not indicate the underlying aetiology. When extended electrophysiological tests revealed multiple subclinical compression neuropathies in the upper limbs, HNPP was contemplated and eventually confirmed by genetic testing.

PURPOSE: To present selected cases that highlight the confusions in daily glaucoma practice. METHODS: Four cases with raised or normal intraocular pressure (IOP) and definite glaucomatous cupping were investigated. RESULTS: While raised IOP was found in non-glaucomatous etiologies, IOP was normal in established glaucoma in a young patient. CONCLUSION: Raised IOP and glaucomatous cupping may not be pathognomonic of glaucoma and alternative etiology should be ruled out for appropriate management.
