The purpose of this study was to compare clinical and radiological outcomes percutaneous endoscopic lumbar discectomy (PELD) open microdiscectomy (OLM) for recurrent disc herniation.Fifty-four patients, who underwent surgery, either PELD (25 patients) or repeated OLM (29 patients), due herniation at L4-5 level, were divided into two groups according the surgical methods. Excluded patients with sequestrated disc, calcified severe neurological deficit, instability. Clinical assessed using...

Although several authors have reported the use of endoscopic techniques to treat lumbar foraminal stenosis, practical application these has been limited soft disc herniation.To describe details percutaneous foraminotomy (ELF) technique for bony stenosis and demonstrate clinical outcomes.Two years prospective data were collected from 33 consecutive patients with who underwent ELF. The surgical outcomes assessed using visual analog scale, Oswestry Disability Index, modified MacNab criteria....

In Brief Study Design. A prospective study. Objective. The purpose of this study was to determine the radiation dose which surgeons are exposed during percutaneous endoscopic lumbar discectomy (PELD) and calculate allowable number cases per year. Summary Background Data. Transforaminal PELD is a minimally invasive technique for soft disc herniation. Minimal invasiveness can be achieved through use fluoroscopy endoscopy. surgeon unknown. Methods. occupational absorbed by 3 spinal performing...

International consensus paper on a unified nomenclature for full-endoscopic spine surgery.Minimally invasive endoscopic spinal procedures have undergone rapid development during the past decade. Evolution of working-channel endoscopes and surgical instruments as well innovation in techniques expanded types pathology that can be addressed. However, there is literature heterogeneous defining approach corridors procedures, this lack common language has hampered communication between surgeons,...

The purpose of this study was to determine the efficacy and feasibility posterolateral percutaneous endoscopic lumbar foraminotomy (PELF) for foraminal or lateral exit zone stenosis L5-S1 level in awake patient. Twelve consecutive patients with associated leg pain underwent PELF between May 2001 July 2002. Under fluoroscopic guidance, decompression performed using a bone reamer, forceps, laser. Using new technique, authors removed part hypertrophied superior facet, thickened ligamentum...

The purpose of this study is to investigate the risk factors for recurrence after successful percutaneous endoscopic lumbar discectomy (PELD). Recently, PELD has become most common surgical technique. However, there are only a few studies on causing reappearance symptoms. Between January 2002 and December 2004, 42 patients with recurrent disc herniation were classified as group who underwent satisfactory result randomly selected non-recurrent group. For all patients, we analyzed medical...

Object The purpose of this study was to evaluate the predictive factors for subsequent vertebral fracture occurring after percutaneous vertebroplasty (PVP) at neighboring levels (adjacent vs nonadjacent levels). Methods medical records 508 consecutive patients treated with PVP between January 2000 and December 2002 were retrospectively reviewed. A total 45 49 painful fractures identified based on clinical radiological findings. New fractures, developing any 3 bodies (VBs) above or below...

Object C-reactive protein (CRP) is a well-known sensitive laboratory parameter that shows an increase within 6 hours after the onset of bacterial infection. In relation to surgery, normal CRP response rapid followed by gradual reduction, eventually returning range. The goal this study was determine diagnostic significance as detector for early surgical site infection in spinal surgery and discuss effective medical treatment through clinical interpretation application measured values. Methods...

Transforaminal percutaneous endoscopic lumbar discectomy (PELD) for high-grade migrated disc herniation has been regarded as a challenging task, but because of the remarkable improvement in navigable instruments and advanced epiduroscopic technique, it can be used treatment high- or very herniation. The purpose this study was to describe detail standardized technique transforaminal PELD demonstrate clinical results.Very defined migration beyond inferior margin pedicle. Thirteen consecutive...

Abstract To evaluate the learning curve of percutaneous endoscopic transforaminal lumbar discectomy (PETLD) from novice stage to proficient stage, we performed retrospective study for patients with disc herniation who underwent PETLD by a single surgeon and evaluated surgeon's effect surgical proficiency on outcomes. A total 48 at lower level (L3–S1) minimum 1-year follow-up were enrolled. The was assessed using cumulative operation time linear regression analyses reveal correlation between...
