The unilateral biportal endoscopic (UBE) technique is a minimally invasive procedure for spinal surgery, while open microscopic discectomy the most common surgical treatment ruptured or herniated discs of lumbar spine. A new that uses UBE approach has been applied to conventional arthroscopic systems disease. In this study, we aimed compare and evaluate perioperative parameters clinical outcomes, including recovery from pain life quality modification, patient’s satisfaction, complications,...

Abstract Introduction: Low back pain is a chronic recurrent symptom, which can lower the patient's quality of life. With technological development automated home massage systems, now offers promising alternative to physiotherapy. However, thus far, effectiveness such methods has not been evaluated. We aimed compare efficacy and cost-effectiveness chair with those conventional physiotherapy for treatment. Methods: This was randomized controlled trial two-group parallel design. Following...

We quantize the bosonized chiral Schwinger model by using systematic Batalin-Fradkin-Vilkovisky formalism. derive a Becchi-Rouet-Stora-Tyutin gauge-fixed covariant action showing that auxiliary fields introduced in formalism turn into Wess-Zumino scalar.

Trans-sacral epiduroscopic lumbar decompression (SELD) is an emerging procedure for the treatment of disc herniation (LDH), with favorable outcomes having been reported. However, complications associated SELD have not comprehensively evaluated to date. Therefore, aim our study was describe incidence rate, types, and characteristics following management outcomes.Retrospective analysis surgical clinical 127 patients (average age, 42.2 ± 15.2 years) who underwent LDH at L2-3, L3-4, L4-5, and/or...

Post-laminectomy syndrome is a common cause of dissatisfaction after endoscopic interlaminar approach. Our aim was to evaluate the efficacy and safety our two newly designed instruments for laminotomy, dural protector attached scope knot pusher water-tight suturing incidental tears.This multicenter evaluation. Efficacy quantified as pre-to-postoperative improvement in pain (visual analog scale), disability (Oswestry Disability Index), patient satisfaction (modified MacNab score), length...

Context/Objective: Trans-sacral epiduroscopic laser decompression (SELD) is an alternative to microscopic open lumbar discectomy (OLD). SELD and OLD for L5-S1 disc herniation (LDH) have not been compared. We compared clinical results, including pain control, between OLD.Design: Retrospective analysis.Setting: Korean hospital.Participants: Eighty patients treated with (n = 40) or LDH.Interventions: N/A.Outcome Measures: Clinical data were over 6 months. Functional status was evaluated using...

Benign spinal cysts are relatively common, but can cause significant pain. However, consensus regarding the best method for treating these has not been established. We aimed to examine usefulness of epiduroscopic neural laser decompression (ENLD), a novel percutaneous treatment, lumbo-sacral cysts.Ten patients (6 men, 4 women; mean age 45.5 years) with benign underwent ENLD. The were caused by multiple pathophysiologies and displayed different characteristics. Cysts evaluated using recorded...

A rare case of solitary diffuse large B-cell lymphoma arising from the lumbar spinal nerve root is reported. 37-year-old man presented with a 3-month history progressive numbness and paraparesis in both legs. The initial diagnosis was benign primary intradural extramedullary tumor including schwannoma meningioma. Histopathological examination revealed lymphoma. While well-defined T1 isointense mass common schwannoma, present atypical had yellowish neural component. pathogenesis radiological...

Abstract Background and Study Aim Reoperation for lumbar spinal stenosis (LSS) is technically challenging. Studies comparing preoperative risk factors reoperation outcomes between fusion decompression are limited. Thus this study compared with respect to rates, related re-surgery, clinical outcomes. Patients Methods This retrospective cohort included prospectively collected data from patients who underwent revision surgeries degenerative LSS May 2001 March 2015. The rate, (proportional...

Superficial siderosis of the central nervous system(SSCNS) is a rare disease characterized by hemosiderin deposition on surface system. We report case SSCNS originating from thoracic spine, presenting with neurological deficits including, sensorineuronal hearing loss, ataxia, and corticospinal dorsal column tract signs. The patient underwent dural repair an artificial patch. Clinical findings were elicited examination, imaging studies, intraoperative findings, these addressed through...

Background and Objectives: The aim of our study was to test whether wide diameter (6 mm) implants perform differently from standard (4 in terms marginal bone level survival rate. Materials Methods: Our sample comprised 72 patients who underwent surgery; a total 80 were placed the maxillary or mandibular molar region. Patients divided into two groups according implant, followed up for six years after final setting prosthetics. In group, 40 with 6-mm inserted; control inserted. Using panoramic...

Abstract Background Lumbar lordosis (LL) can be restored, and screw-related complications may avoided with the stand-alone expandable cage method. However, long-term spinopelvic changes safety remain unknown. We aimed to elucidate radiologic outcomes of this technique. Methods Data from patients who underwent multi-level fusion 80 screw-assisted between February 2007 December 2012, at least 5 years follow-up, were retrospectively analyzed. Segmental angle translation, short whole LL, pelvic...

Background and Objectives: Biportal endoscopic spine surgery (BESS) is a promising technique that can be applied for the treatment of various spinal diseases. However, traditional BESS procedures require multiple, separate incisions. We present, herein, techniques to reduce number incisions in multi-level their clinical outcomes. Materials Methods: Three different were used preservation normal tissue associated with BESS: step-ladder technique, employing common portal scope instruments;...

Without resorting to the symplectic condition, we rigorously study constraint structure of topologically massive theory with one- and two-form fields in framework Batalin–Fradkin–Tyutin Hamiltonian embedding procedure. Through this full analysis obtain a new type Wess–Jumino action novel symmetry, which is originated from topological coupling term, as well Stückelberg related explicit gauge breaking mass terms original theory.

Abstract Background and Study Aims Lumbar spinal stenosis (LSS) is the most common disease in older adults. Although surgical modalities are recommended patients who unresponsive to conservative treatment, appropriate minimally invasive procedure for with LSS remains controversial. Moreover, few previous studies have focused on patient-centered outcomes radiologic correlation. In present study, we aimed investigate efficacy patient satisfaction following bilateral decompression via...

Perineural (Tarlov) cysts are a common benign pathology in the lumbosacral area but rarely symptomatic, even when compressing spinal root. Despite rarity of Tarlov cyst formation foramen spine, this type is more symptomatic than those other sites due to narrow space. We introduce biportal endoscopic fenestration for foraminal cysts. present case 40-year-old woman experiencing radiating pain her right lower leg 4 years. On seeking treatment, great toe and ankle plantar flexion power had...
