Efficacy evaluation of Mongolian medical warm acupuncture for sciatica caused by lumbar disc herniation: a randomized, controlled, single-blind clinical trial.

OBJECTIVE: This study aimed to evaluate the short-term and long-term efficacy of Mongolian medical warm acupuncture for sciatica caused by lumbar disc herniation (LDH). PATIENTS AND METHODS: The patients diagnosed with sciatica caused by LDH were randomly divided into the warm acupuncture of the Mongolian medicine group (n = 42, warm acupuncture treatment), the sham acupuncture group (n = 38, sham acupuncture using blunt-tipped needles) and the conventional drug group (n = 40, ibuprofen sustained release capsule). All patients were treated for 4 weeks and followed up for 8 weeks. The visual analog scale for leg pain (VAS-LP), Mongolian medicine indicators (efficacy indicators), VAS for waist pain (VAS-WP) and the Mos 36-item short form health survey (SF-36) score were analyzed at baseline, after two-week treatment, after four-week treatment, at four-week follow-up and at eight-week follow-up. RESULTS: Warm acupuncture treatment significantly decreased the VAS-LP and VAS-WP scores of patients at treatment and follow-up (p < 0.05), and pain was improved compared to the conventional drug group and sham acupuncture group. The total effective rate was markedly higher in the warm acupuncture of the Mongolian medicine group compared with the conventional drug group at 8-week follow-up (p < 0.05), but sham acupuncture treatment resulted in no evident improvement in the Mongolian medicine indicators. Additionally, at treatment and follow-up, warm acupuncture of the Mongolian medicine group showed a significant increase in the physical function, physical role, body pain, and emotional and mental health role scores of the SF-36 survey compared with the sham acupuncture groups. CONCLUSIONS: Mongolian medical warm acupuncture effectively relieves leg and waist pain and improves the total therapeutic effect and the quality of daily life for patients with sciatica caused by LDH, with significant long-term efficacy. Our study provides a basis for warm acupuncture in the treatment of sciatica caused by LDH. Chinese Clinical Trial Registry ID: ChiCTR- INR-15007413.

Sciatica caused by spinal epidural abscess as the initial clinical presentation of colon cancer: a rare case report and review of literature.

BACKGROUND: Colorectal cancer is one of the most frequently diagnosed forms of cancer, and it is associated with several common symptoms and signs such as rectal bleeding, altered bowel habits, abdominal pain, anemia, and unintentional weight loss. Sciatica, a debilitating condition in which the patient experiences paresthesia and pain in the dermatome of associated lumbosacral nerve roots or sciatic nerve distribution, is not considered one of these. Here we present a case of colorectal cancer manifesting symptoms of sciatica alone. CASE PRESENTATION: A 68-year-old male presented with progressive lower back pain radiating to his left thigh and calf over L5/S1 dermatome. Sciatica was suspected and initially underwent conservative treatment with analgesics. However, the symptoms progressed and MRI revealed an epidural abscess surprisingly. Surgical debridement was performed and pus culture isolated Streptococcus gallolyticus. Based on the strong association of S. gallolyticus with colorectal cancer, the presence of this pathogen prompted further tumor evaluation, even in the absence of the typical symptoms and signs. This investigation ultimately leads to the diagnosis of sigmoid adenocarcinoma. CONCLUSIONS: Although rare, sciatica caused by S. gallolyticus infection of the spinal epidural space may serve as the initial presentation of colorectal cancer. Physicians should be aware of the strong association between S. gallolyticus and colorectal cancer. Based on what we currently know about the condition; a thorough systematic assessment of occult neoplasia for patients with S. gallolyticus infection is recommended.

Mitigation of sciatica injury-induced neuropathic pain through active metabolites derived from medicinal plants.

Sciatica characterized by irritation, inflammation, and compression of the lower back nerve, is considered one of the most common back ailments globally. Currently, the therapeutic regimens for sciatica are experiencing a paradigm shift from the conventional pharmacological approach toward exploring potent phytochemicals from medicinal plants. There is a dire need to identify novel phytochemicals with anti-neuropathic potential. This review aimed to identify the potent phytochemicals from diverse medicinal plants capable of alleviating neuropathic pain associated with sciatica. This review describes the pathophysiology of sciatic nerve pain, its cellular mechanisms, and the pharmacological potential of various plants and phytochemicals using animal-based models of sciatic nerve injury-induced pain. Extensive searches across databases such as Medline, PubMed, Web of Science, Scopus, ScienceDirect, and Google Scholar were conducted. The findings highlights 39 families including Lamiaceae, Asteraceae, Fabaceae, and Apocyanaceae and Cucurbitaceae, effectively treating sciatic nerve injury-induced pain. Flavonoids made up 53% constituents, phenols and terpenoids made up 15%, alkaloids made up 13%, and glycosides made up 6% to be used in neuorpathic pain. Phytochemicals derived from various medicinal plants can serve as potential therapeutic targets for both acute and chronic sciatic injury-induced neuropathic pain.

Biphasic release of betamethasone from an injectable HA hydrogel implant for alleviating lumbar disc herniation induced sciatica.

Epidural steroid injection (ESI) is a common therapeutic approach for managing sciatica caused by lumbar disc herniation (LDH). However, the short duration of therapeutic efficacy and the need for repeated injections pose challenges in LDH treatment. The development of a controlled delivery system capable of prolonging the effectiveness of ESI and reducing the frequency of injections, is highly significant in LDH clinical practice. In this study, we utilized a thiol-ene click chemistry to create a series of injectable hyaluronic acid (HA) based release systems loaded with diphasic betamethasone, including betamethasone dipropionate (BD) and betamethasone 21-phosphate disodium (BP) (BD/BP@HA). BD/BP@HA hydrogel implants demonstrated biocompatibility and biodegradability to matched neuronal tissues, avoiding artificial compression following injection. The sustained release of betamethasone from BD/BP@HA hydrogels effectively inhibited both acute and chronic neuroinflammation by suppressing the nuclear factor kappa-B (NF-κB) pathway. In a mouse model of LDH, the epidural administration of BD/BP@HA efficiently alleviated LDH-induced sciatica for at least 10 days by inhibiting the activation of macrophages and microglia in dorsal root ganglion and spinal dorsal horn, respectively. The newly developed HA hydrogels represent a valuable platform for achieving sustained drug release. Additionally, we provide a simple paradigm for fabricating BD/BP@HA for epidural injection, demonstrating greater and sustained efficiency in alleviating LDH-induced sciatica compared to traditional ESI and displaying potentials for clinical translation. This system has the potential to revolutionize drug delivery for co-delivery of both soluble and insoluble drugs, thereby making a significant impact in the pharmaceutical industry. STATEMENT OF SIGNIFICANCE: Lumbar disc herniation (LDH) is a common degenerative disorder leading to sciatica and spine surgery. Although epidural steroid injection (ESI) is routinely used to alleviate sciatica, the efficacy is short and repeated injections are required. There remains challenging to prolong the efficacy of ESI. Herein, an injectable hyaluronic acid (HA) hydrogel implant by crosslinking acrylated-modified HA (HA-A) with thiol-modified HA (HA-SH) was designed to achieve a biphasic release of betamethasone. The hydrogel showed biocompatibility and biodegradability to match neuronal tissues. Notably, compared to traditional ESI, the hydrogel better alleviated sciatica in vivo by synergistically inhibiting the neuroinflammation in central and peripheral nervous systems. We anticipate the injectable HA hydrogel implant has the potential for clinical translation in treating LDH-induced sciatica.

Anatomical Relationships of the Sciatic Nerve and Pudendal Nerve to the Ischial Spine as They Exit the Greater Sciatic Foramen.

OBJECTIVE: Deep gluteal syndrome is a clinical condition in which discomfort may arise due to the pathoanatomy of the subgluteal space. We conducted an anatomical exploration to categorize the relationship of the piriformis muscle, sciatic nerve (SN), and pudendal nerve (PN) to the ischial spine (IS) and sacrospinous ligament. METHODS: We analyzed 22 cadavers. The piriformis muscle, SN, and PN were exposed through either a transgluteal approach or a gluteal flap. The relationship of the neural structures to the IS, sacrospinous ligament, and ischial bone as they exit the greater sciatic foramen was observed, and the exit zones were classified as zone A, medial to the IS (entirely on sacrospinous ligament); zone B, on the IS; and zone C, lateral to the IS (entirely on ischial bone). RESULTS: The SN was observed either in zone B or zone C in all specimens. The PN was found to be in either zone A or zone B in 97.6% of specimens. The most common combinations were SN in zone B and PN in zone A (type I), and SN in zone C and PN in zone B (type II). CONCLUSIONS: The results from this study show clear anatomical differences in the SN-PN relationship, which may play a role in pain seen in deep gluteal syndrome. Moreover, classification of the SN-IS and PN-IS relationships described in this article will help describe different pathologies affecting the deep gluteal area.

Combined Rehabilitation with Alpha Lipoic Acid, Acetyl-L-Carnitine, Resveratrol, and Cholecalciferolin Discogenic Sciatica in Young People: A Randomized Clinical Trial.

Background and Objectives: In the Western world, back pain and sciatica are among the main causes of disability and absence from work with significant personal, social, and economic costs. This prospective observational study aims to evaluate the effectiveness of a rehabilitation program combined with the administration of Alpha Lipoic Acid, Acetyl-L-Carnitine, Resveratrol, and Cholecalciferol in the treatment of sciatica due to herniated discs in young patients in terms of pain resolution, postural alterations, taking painkillers, and quality of life. Materials and Methods: A prospective observational study was conducted on 128 patients with sciatica. We divided the sample into 3 groups: the Combo group, which received a combination of rehabilitation protocol and daily therapy with 600 mg Alpha Lipoic Acid, 1000 mg Acetyl-L-Carnitine, 50 mg Resveratrol, and 800 UI Cholecalciferol for 30 days; the Reha group, which received only a rehabilitation protocol; and the Supplement group, which received only oral supplementation with 600 mg Alpha Lipoic Acid, 1000 mg Acetyl-L-Carnitine, 50 mg Resveratrol, and 800 UI Cholecalciferol. Clinical assessments were made at the time of recruitment (T0), 30 days after the start of treatment (T1), and 60 days after the end of treatment (T2). The rating scales were as follows: the Numeric Rating Scale (NRS); the Oswestry Disability Questionnaire (ODQ); and the 36-item Short Form Health Survey (SF-36). All patients also underwent an instrumental stabilometric evaluation. Results: At T1, the Combo group showed statistically superior results compared to the other groups for pain (p < 0.05), disability (p < 0.05), and quality of life (p < 0.05). At T2, the Combo group showed statistically superior results compared to the other groups only for pain (p < 0.05) and quality of life (p < 0.05). From the analysis of the stabilometric evaluation data, we only observed a statistically significant improvement at T2 in the Combo group for the average X (p < 0.05) compared to the other groups. Conclusions: The combined treatment of rehabilitation and supplements with anti-inflammatory, pain-relieving, and antioxidant action is effective in the treatment of sciatica and can be useful in improving postural stability.

Predictors of outcome in sciatica patients following an epidural steroid injection: the POiSE prospective observational cohort study protocol.

INTRODUCTION: Sciatica can be very painful and, in most cases, is due to pressure on a spinal nerve root from a disc herniation with associated inflammation. For some patients, the pain persists, and one management option is a spinal epidural steroid injection (ESI). The aim of an ESI is to relieve leg pain, improve function and reduce the need for surgery. ESIs work well in some patients but not in others, but we cannot identify these patient subgroups currently. This study aims to identify factors, including patient characteristics, clinical examination and imaging findings, that help in predicting who does well and who does not after an ESI. The overall objective is to develop a prognostic model to support individualised patient and clinical decision-making regarding ESI. METHODS: POiSE is a prospective cohort study of 439 patients with sciatica referred by their clinician for an ESI. Participants will receive weekly text messages until 12 weeks following their ESIand then again at 24 weeks following their ESI to collect data on leg pain severity. Questionnaires will be sent to participants at baseline, 6, 12 and 24 weeks after their ESI to collect data on pain, disability, recovery and additional interventions. The prognosis for the cohort will be described. The primary outcome measure for the prognostic model is leg pain at 6 weeks. Prognostic models will also be developed for secondary outcomes of disability and recovery at 6 weeks and additional interventions at 24 weeks following ESI. Statistical analyses will include multivariable linear and logistic regression with mixed effects model. ETHICS AND DISSEMINATION: The POiSE study has received ethical approval (South Central Berkshire B Research Ethics Committee 21/SC/0257). Dissemination will be guided by our patient and public engagement group and will include scientific publications, conference presentations and social media.

[Foot drop and cyclic sensory disturbance of the right lower limb due to endometriosis].

We report the case of a 40-year-old woman, with endometriosis, who presented with a history of foot drop and cyclic sensory disturbance of the right lower limb. She was initially diagnosed with lumbar disc herniation. Neurological examination revealed muscle weakness and sensory disturbance associated with the right sciatic nerve. Nerve conduction studies revealed a low amplitude sensory nerve action potential in the right superficial fibular and sural nerves. Pelvic magnetic resonance imaging revealed an endometriotic cyst in the right ovary, and an endometriotic lesion extending from the right ovary, pelvis, and the right sciatic nerve. Though her symptoms moderately improved with hormonal therapy, the foot drop remained. Our case and previous reports suggest that endometriosis with sciatic neuropathy shows cyclic neurological symptoms during menstruation, with a higher incidence on the right extremity. This case highlights that endometriosis should be considered as a potential differential diagnosis in women of reproductive age with sciatic nerve dysfunction. Its cyclic neurological manifestations should be investigated.

Clinical Efficacy of Acupuncture with Canggui Tanxue Technique on Huantiao Point for Treating Sciatica Caused by Lumbar Disc Herniation.

Objective: The present study aimed to assess the clinical efficacy of acupuncture with the Canggui Tanxue Technique on the Huantiao point for treating sciatica caused by lumbar disc herniation. Methods: This randomized controlled trial evaluated outpatient and inpatient data of patients from the Department of Acupuncture and Encephalopathy at Yancheng City Hospital of Traditional Chinese Medicine, Nanjing University of Traditional Chinese Medicine, between March 2020 and October 2022. A total of 100 eligible cases were recruited. Patients were randomly assigned using a random number table method at a ratio of 1:1 to receive either routine acupuncture technique on the Huantiao point (control group) or Canggui Tanxue Technique on the Huantiao point (Canggui Tanxue group), with 50 cases in each group. Outcome measures included post-treatment pain and clinical efficacy. Results: Canggui Tanxue Technique demonstrated significant pain reduction and improved functional restoration compared to the routine technique, as evidenced by significantly lower scores on the Visual Analogue Scale (VAS), Japanese Orthopaedic Association (JOA) scores, and Roland-Morris Disability Questionnaire (RDQ) scores (P < .05). Patients receiving acupuncture with Canggui Tanxue Technique exhibited significantly higher clinical efficacy compared to those receiving the routine technique (P < .05). Conclusion: Acupuncture with Canggui Tanxue Technique on the Huantiao point provides superior pain reduction and functional restoration for patients with sciatica caused by lumbar disc herniation compared to routine techniques. This approach offers high safety, potent efficiency, and better operability.

Clinical Effectiveness of Single Lumbar Periradicular Infiltration in Patients with Sciatica.

Periradicular therapy (PRT) is a minimally invasive radiological procedurein patients with chronic lumbar pain.The aim of the study is to identify clinical and radiological predictive factors for treatment success after a single PRT treatment in patients with sciatica.The study includes a prospective follow-up of 166 patients treated with PRT. The pain intensity is determined according to the VAS scale and the degree of improvement is presented as excellent (over 75%), good (50-70%), moderate (25-49%), and weak (less than 25%). The follow up of the treated patients was done at 2 weeks, 3 and 6 months. In patients with pain duration up to 3 months, the improvement was excellent in n=32 (58.18%) after 2 weeks, after 3 months n=41 (74.55%) and after 6 months n=41 (74.55%). This stands in contrast to patients with pain over 1 year. The percentage of improvement after 6 months, post-intervention, was highest in patients without nerve root compression (86.25±19.2),and the highest improvement after 6 months was in patients with localization of pain at the L4-L5 level (69.69±29.7), the greatest improvement after six months was in patients with extraforaminal hernia (62.82±34.3), and the lowest in patients with central stenosis (40.21±30.7).Our study results suggest that the shorter a pain duration, low-grade root compression, injection level and type of herniation area predictor the more favourable response patients have to transforaminal epidural steroid injection in patients with sciatica.

Full-endoscopic foraminotomy in low-grade degenerative and isthmic spondylolisthesis: a patient-specific tailored approach.

PURPOSE: To describe the surgical technique and methodology to successfully plan and execute an endoscopic foraminotomy in patients with isthmic or degenerative spondylolisthesis, according to each patient's unique characteristics. METHODS: Thirty patients with degenerative or isthmic spondylolisthesis (SL) with radicular symptoms were included from March 2019 to September 2022. Treating physician registered patients' baseline and imaging characteristics, as well as preoperative back pain VAS, leg pain VAS and ODI. Subsequently, authors treated the included patients with an endoscopic foraminotomy according to a "patient-specific" tailored approach. RESULTS: Nineteen patients (63.33%) had isthmic SL and 11 patients (36.67%) had degenerative SL. 75.86% of the cases had a Meyerding Grade 1 listhesis. One of the transforaminal foraminotomies with lateral recess decompression in degenerative SL had to be aborted because of intense osseous bleeding. Of the remaining 29 patients, one patient experienced recurrence of the sciatica pain that required subsequent reintervention and fusion. No other intraoperative or post-operative complications were observed. None of the patients developed post-operative dysesthesia. In 86.67% of the patients, the foraminotomy was implemented using a transforaminal approach. In the remaining 13.33% of the cases, an interlaminar contralateral approach was used. Lateral recess decompression was performed in half of the cases. Mean follow-up time was 12.69 months, reaching a maximum of 40 months in some patients. Outcome variables such as VAS for leg and back pain, as well as ODI, showed statistically significant reduction since the 3-month follow-up visit. CONCLUSION: In the presented case series, endoscopic foraminotomy achieved satisfactory outcomes without sacrificing segmental stability. The proposed patient-specific "tailored" approach allowed to successfully design and execute the surgical strategy to perform an endoscopic foraminotomy through transforaminal or interlaminar contralateral approaches.

Occult proximal femoral fracture with radiating leg pain masquerading as sciatica: a case report.

BACKGROUND: Occult proximal femoral fractures do not appear as fracture lines in radiographs, causing misdiagnosis and delayed diagnosis unless additional imaging studies, such as computed tomography or magnetic resonance imaging, are performed. Here, we present a 51-year-old male with an occult proximal femoral fracture who experienced radiating unilateral leg pain that took 3 months to be diagnosed because his symptoms mimicked lumbar spine disease. CASE PRESENTATION: A 51-year-old Japanese male experienced persistent lower back and left thigh pain after falling off a bicycle, and was referred to our hospital 3 months thereafter. Whole-spine computed tomography and magnetic resonance imaging revealed minute ossification of the ligamentum flavum at T5/6 without spinal nerve compression, but this did not explain his leg pain. Additional magnetic resonance imaging of the hip joint revealed a fresh left proximal femoral fracture without displacement. He underwent surgery for in situ fixation using a compression hip screw. Post-surgical pain relief was immediate. CONCLUSIONS: Misdiagnosis of occult femoral fractures as lumbar spinal disease may occur if distally radiating referred pain is present. Hip joint disease should be considered as a differential diagnosis in cases of sciatica-like pain with an unknown spinal origin and no specific findings on spinal computed tomography or magnetic resonance imaging accounting for the leg pain, especially following trauma.

CT-guided Pulsed Radiofrequency Combined with Steroid Injection for Sciatica from Herniated Disk: A Randomized Trial.

Background Evidence regarding effective nonsurgical management of sciatica remains limited. Purpose To determine a difference in effectiveness between combined pulsed radiofrequency (PRF) and transforaminal epidural steroid injection (TFESI) treatment versus TFESI alone for sciatic pain due to lumbar disk herniation. Materials and Methods This prospective multicenter double-blind randomized clinical trial was conducted between February 2017 and September 2019 in participants with sciatica due to lumbar disk herniation lasting 12 weeks or longer that was not responsive to conservative treatment. Study participants were randomly assigned to undergo one CT-guided treatment with combined PRF and TFESI (n = 174) or TFESI alone (n = 177). The primary outcome was leg pain severity, as assessed with the numeric rating scale (NRS) (range, 0-10) at weeks 1 and 52 after treatment. Secondary outcomes included Roland-Morris Disability Questionnaire (RMDQ) score (range, 0-24) and Oswestry Disability Index (ODI) score (range, 0-100). Outcomes were analyzed according to the intention-to-treat principle via linear regression. Results Mean age of the 351 participants (223 men) was 55 years ± 16 (SD). At baseline, NRS was 8.1 ± 1.1 in the PRF and TFESI group and 7.9 ± 1.1 in the TFESI group. NRS was 3.2 ± 0.2 in the PRF and TFESI group and 5.4 ± 0.2 in the TFESI group (average treatment effect, 2.3; 95% CI: 1.9, 2.8; P < .001) at week 1 and 1.0 ± 0.2 and 3.9 ± 0.2 (average treatment effect, 3.0; 95% CI: 2.4, 3.5; P < .001), respectively, at week 52. At week 52, the average treatment effect was 11.0 (95% CI: 6.4, 15.6; P < .001) for ODI and 2.9 (95% CI: 1.6, 4.3; P < .001) for RMDQ, favoring the combined PRF and TFSEI group. Adverse events were reported in 6% (10 of 167) of participants in the PRF and TFESI group and in 3% (six of 176) of participants in the TFESI group (eight participants did not complete follow-up questionnaires). No severe adverse events occurred. Conclusion In the treatment of sciatica caused by lumbar disk herniation, pulsed radiofrequency combined with transforaminal epidural steroid injection is more effective for pain relief and disability improvement than steroid injection alone. © RSNA, 2023 Supplemental material is available for this article.

Variant Sciatic Nerve Anatomy in Relation to the Piriformis Muscle on Magnetic Resonance Neurography: A Potential Etiology for Extraspinal Sciatica.

OBJECTIVE: To assess the prevalence and clinical implications of variant sciatic nerve anatomy in relation to the piriformis muscle on magnetic resonance neurography (MRN), in patients with lumbosacral neuropathic symptoms. MATERIALS AND METHODS: In this retrospective single-center study, 254 sciatic nerves, from 127 patients with clinical and imaging findings compatible with extra-spinal sciatica on MRN between 2003 and 2013, were evaluated for the presence and type of variant sciatic nerves, split sciatic nerve, abnormal T2-signal hyperintensity, asymmetric piriformis size and increased nerve caliber, and summarized using descriptive statistics. Two-tailed chi-square tests were performed to compare the anatomical variant type and clinical symptoms between imaging and clinical characteristics. RESULTS: Sixty-four variant sciatic nerves were identified with an equal number of right and left variants. Bilateral variants were noted in 15 cases. Abnormal T2-signal hyperintensity was seen significantly more often in variant compared to conventional anatomy (40/64 vs. 82/190; p = 0.01). A sciatic nerve split was seen significantly more often in variant compared to conventional anatomy (56/64 vs. 20/190; p < 0.0001). Increased nerve caliber, abnormal T2-signal hyperintensity, and asymmetric piriformis size were significantly associated with the clinically symptomatic side compared to the asymptomatic side (98:2, 98:2, and 97:3, respectively; p < 0.0001 for all). Clinical symptoms were correlated with variant compared to conventional sciatic nerve anatomy (64% vs. 46%; p = 0.01). CONCLUSION: Variant sciatic nerve anatomy, in relation to the piriformis muscle, is frequently identified with MRN and is more likely to be associated with nerve signal changes and symptomatology.

Atypical Cause for Back Pain and Sciatica in a 35-Yr-Old Woman With Fibromyalgia.

ABSTRACT: Spinal and extrapelvic lesions causing sciatic symptoms are well recognized in clinical research and practice. 1-5 We present a 35-yr-old woman with a history of axial back pain and fibromyalgia who presented with episodes of radicular type pain down her legs and associated bilateral tingling in her feet. Medicinal and therapeutic interventions for traditional sciatica etiologies failed to provide relief. Lumbar magnetic resonance imaging showed mild multilevel degenerative changes and partially visualized fibroids, but no other significant spinal pathology was appreciated. Subsequent pelvic magnetic resonance imaging revealed an enlarged retroverted uterus with multiple fibroid lesions. The patient elected for laparoscopic myomectomy, which improved her likelihood of fertility while drastically alleviating her axial spine and lower extremity symptomology. This case reinforces the importance of keeping a broad differential that includes intrapelvic etiologies when traditional workup and treatment for sciatic neuropathy fails. To our knowledge, this is the first reported case of sciatic neuropathy secondary to uterine fibroids treated with the intent of both fertility improvement and pain relief.

Focused Extracorporeal Shock Wave Therapy for Ischial Apophysitis in Young High-Level Gymnasts.

OBJECTIVE: We aimed to investigate the effect and safety of extracorporeal shock wave therapy (ESWT) on ischial apophysitis (IA) in young high-level gymnasts. We hypothesized that ESWT would be safe and effective in alleviating pain. DESIGN: Retrospective case series. SETTING: Funabashi Orthopedic Hospital. PATIENTS: The subjects were 18 high-level gymnasts (mean age of 13 years) with a chief complain of chronic buttock pain diagnosed with IA. INTERVENTIONS: Ten patients received only physiotherapy (PT), whereas 8 received both PT and ESWT to the ischial tuberosity. The basic protocol for ESWT was to use an energy dose of 0.20 mJ/mm 2 or less with 3000 shots per session at 4-week intervals. MAIN OUTCOME MEASURES: We investigated whether PT and ESWT relieved the pain and allowed the patient to return fully to gymnastics. Based on radiographs at the last observation, we examined whether early closure of the apophyseal line of the ischium and around hip joint on the affected side occurred. RESULTS: In the PT group, pain was relieved in 2 of 10 patients. In the ESWT group, pain was relieved and full return to gymnastics was possible in all 8 patients. None of the patients showed early closure of the apophyseal line. CONCLUSIONS: Extracorporeal shock wave therapy can be a safe and effective treatment option for IA in young high-level gymnasts.

Efficacy and safety of warm acupuncture combined with Western medicine for sciatica: A protocol for systematic review and meta-analysis.

BACKGROUND: There are more and more clinical studies on the efficacy of warm acupuncture in treating sciatica, but the systematic review of the efficacy of warm acupuncture is still lacking. The objective of this study was to evaluate the efficacy and safety of warm acupuncture combined with conventional Western medicine in the treatment of sciatica. METHODS: The review was registered in the PROSPERO database (CRD42022379486) and was conducted according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines. The following databases will be used to search the existing literature (from inception to January 2023): Web of Science, Embase, Cochrane Library, PubMed, Cumulative Index to Nursing and Allied Health Literature, Wanfang, Allied and Complementary Medicine Database, China Knowledge Network, and SPORT-Discus. Included studies are considered eligible if they met the population, intervention, comparator, outcomes, and study design criteria as follows: Population: patients with newly diagnosed sciatica; Intervention: warm acupuncture combined with conventional Western medicine; Comparator: Western medicine alone; Outcomes: total response rate, pain score and pain threshold, adverse events and recurrence rate. Study design: randomized controlled trials or non-randomized cohort studies. Review Manager (RevMan) V.5.3 will be used to perform statistical analyses and to generate forest plots. RESULTS: The review will add to the existing literature by showing compelling evidence and improved guidance in clinic settings.

A Sciatic Neuralgia Case of an Entrapment Neuropathy Mimicking Piriformis Syndrome Due to Soft Tissue Hemangioma.

BACKGROUND: Lumbosacral pain is commonly seen in daily clinical practice. In fact, entrapment of the part of the sciatic nerve after the sacral foramen causes some of these pains, which should not be overlooked. The sciatic nerve may be compressed during its course after the sacral foramen for a variety of reasons. We aimed in this article to review extra-spinal compressive sciatic neuropathy reasons and abnormal magnetic resonance imaging (MRI) by presenting a sciatic neuralgia case of an entrapment neuropathy mimicking piriformis syndrome due to soft tissue hemangioma. CASE PRESENTATION: A 30-year-old male patient was admitted with complaints of lumbosacral pain spreading to the leg that had been worsening over the previous 10 days. With the preliminary diagnosis of labral damage and piriformis syndrome, the patient was referred to the radiology clinic for a hip MRI. In the hip MR images, a mass lesion suggestive of heterogeneously enhanced soft tissue hemangioma after the injection of paramagnetic contrast material was observed in the proximal left thigh. The soft tissue hemangioma extends towards the obturator foramen and compresses the sciatic nerve proximal to the femur after the sciatic foramen. CONCLUSION: The diagnosis of lower extremity entrapment neuropathy is frequently misdiagnosed. In these cases, MRI becomes more important for accurate diagnosis. The radiologists' knowledge of the sciatic nerve in MRI, regional anatomy during the course of the sciatic nerve, and abnormal nerve imaging findings will aid in the diagnosis.
