Retrospective radiologic study on a prospective patient cohort.To devise qualitative grading of lumbar spinal stenosis (LSS), its reliability and clinical relevance.Radiologic is assessed commonly by measuring dural sac cross-sectional area (DSCA). Great variation observed though in surfaces recorded between symptomatic asymptomatic individuals.We describe 7-grade classification based the morphology as T2 axial magnetic resonance images rootlet/cerebrospinal fluid ratio. Grades A B show...

Study Design. A retrospective radiological study. Objective. The aim of this study was to evaluate the accuracy pedicle screw insertion using O-Arm navigation, robotic assistance, or a freehand fluoroscopic technique. Summary Background Data. Pedicle either “O-Arm” navigation devices is gaining popularity. Although several studies are available evaluating each those techniques separately, no direct comparison has been attempted. Methods. Eighty-four patients undergoing implantation 569...

Study Design. Delphi. Objective. The aim of this study was to obtain an expert consensus on which history factors are most important in the clinical diagnosis lumbar spinal stenosis (LSS). Summary Background Data. LSS is a poorly defined syndrome. Criteria for defining needed and should be informed by experience clinicians. Methods. Phase 1 (Delphi Items): 20 members International Taskforce Diagnosis Management confirmed list 14 items. An online survey developed that permits specialists...

Chronic low back pain attributed to lumbar disc degeneration poses a serious challenge physicians. Surgery may be indicated in selected cases following failure of appropriate conservative treatment. For decades, the only surgical option has been spinal fusion, but its results have inconsistent. Some prospective trials show superiority over usual measures while others fail demonstrate advantages. In an effort improve fusion and decrease incidence adjacent segment degeneration, total...

Abstract OBJECTIVE: Minimally invasive spinal techniques have been developed for years in an attempt to minimize trauma. However, most endoscopic unable address uncontained or large contained disc herniations. The aim of this prospective study was compare the results microendoscopic discectomy (MED) and microsurgical treatment patients with METHODS: An independent observer reviewed 28 patients. group included 14 consecutive who underwent MED radicular pain secondary herniations during same...

Surgical decision-making in lumbar spinal stenosis involves assessment of clinical parameters and the severity radiological stenosis. We suspected that surgeons based surgical decisions more on dural sac cross-sectional area (DSCA) than morphology sac. carried out a survey among members three European spine societies. The axial T2-weighted MR images from ten patients with varying degrees DSCA morphological grades according to recently described classification stenosis, values disclosed half...

Current restrictions for human cell-based therapies have been related to technological limitations with regards cellular proliferation capacity, maintenance of differentiated phenotype primary cell culture, and transmission communicable diseases. We seen that cultured fetal cells from one organ donation could possibly meet the exigent stringent technical aspects development therapeutic products. develop a master bank (MCB) 50 homogenous ampoules 4-5 million each (skin) in short periods time...

Tissue-specific stem cells found in adult tissues can participate the repair process following injury. However, tissues, such as articular cartilage and intervertebral disc, have low regeneration capacity, whereas fetal cartilage, show high ability. The presence of cartilaginous their involvement is unknown. aim study was to assess chondrogenic differentiation plasticity cells. We compared TGF-β3-induced human isolated from spine that bone marrow stromal (BMSC). Stem cell surface markers...

Photopolymerization is commonly used in a broad range of bioapplications, such as drug delivery, tissue engineering, and surgical implants, where liquid materials are injected then hardened by means illumination to create solid polymer network. However, photopolymerization using probe, e.g., needle guiding both the curing illumination, has not been thoroughly investigated. We present Monte Carlo model that takes into account dynamic absorption scattering parameters well solid–liquid...
