This retrospective, questionnaire-based investigation evaluated iliac crest bone graft (ICBG) site morbidity in patients having undergone a single-level anterior cervical discectomy and fusion (ACDF) procedure performed by single surgeon (T.J.A.).To evaluate acute chronic problems associated with ICBG donation, particularly long-term functional outcomes impairments caused donation.Anterior procedures frequently use autologous to facilitate osseous union. Although offers several advantages...
A prospective, multicenter, cross-sectional analysis of data from the National Spine Network database.To compare relative impact radicular and axial symptoms associated with disease cervical spine on general health as measured by SF-36 Health Survey, to these among patients varying age symptom duration.Degenerative disorders can cause debilitating neck arm pain. Physicians generally treat radiculopathy more aggressively than pain alone, although it has never been shown that presence leads a...
The radiographs of 35 consecutive adult patients with isthmic spondylolisthesis who underwent a transforaminal lumbar interbody fusion (TLIF) one or two Brantigan carbon fiber cages and pedicle screw instrumentation were evaluated. Anterolisthesis, disk space height, slip angle measured in preoperative postoperative standing neutral radiographs. Anterolisthesis was reduced height increased the TLIF procedure. Average angle, however, not significantly altered. restoration lordosis across...
Retrospective database review.To determine the variability in cost and surgical technique by geographic region patient demographic.Some patients with idiopathic scoliosis (IS) ultimately require treatment. The costs associated hospitalization can be substantial, yet it is unknown how these vary depending on region.Patients aged 10 to 24 who underwent fusion for from 2004 2006 were identified a publicly available, searchable national of insurance billing records orthopaedic diagnoses...
Two experiments were conducted. Experiment 1 evaluated the effect of 3 kinds decellularized extracellular matrices (DECMs) deposited by synovium-derived stem cells (SDSCs) and/or nucleus pulposus (NPCs) on SDSC expansion and NP lineage differentiation. 2 DECM SDSCs NPC redifferentiation capacity. In both experiments, hypoxia was in preparation pellet culture.Modulating vitro microenvironment facilitates SDSC-based tissue regeneration.Autologous cell therapy is a promising approach for...
Background: Ischemic optic neuropathy resulting in visual loss is a rare but devastating complication of spine surgery. Elevated intraocular pressure (IOP) results decreased perfusion and possibly ischemic neuropathy. We performed randomized, prospective trial to evaluate the effect head positioning on IOP during lumbar fusion. Methods: The study included fifty-two patients treated at one institution. Inclusion criteria were fusion an age eighteen eighty years. Exclusion diagnosis tumor,...
The operative care of patients with ankylosing spinal conditions such as spondylitis (AS) and diffuse idiopathic skeletal hyperostosis (DISH) after a spine fracture is not well represented in the literature. This work seeks to determine effect minimally invasive techniques on fractures through retrospective case-control analysis.The logs from 1996-2013 seven fellowship-trained surgeons two academic, Level I trauma centers were reviewed for cases operatively treated thoracic lumbar...
Background: Dysphagia is one of the most common complications surgical procedures in anterior cervical spine, and can persist up to 2 years postoperatively. Corticosteroids are relatively safe inexpensive for treating various inflammatory conditions. Perioperative corticosteroid administration spine may effectively minimize postoperative dysphagia, potentially leading better outcomes, decreased readmission rates, improved patient satisfaction. The purpose this study was determine efficacy...
Prospective cohort study.To precisely measure the effect of anterior cervical fusion on neck motion.Anterior decompression and stabilization procedures are successful in treating recalcitrant radiculopathy myelopathy. Most assume that these "fusion" result a loss motion, although changes overall motion following have never been quantified.Twenty-five consecutive patients undergoing one to four levels underwent range testing three planes using an unconstrained instrumented linkage before...
In Brief Study design. Retrospective radiographic review. Objective. To investigate the effects of cervical disc herniation on kinematics at adjacent vertebral motion segments. Summary Background Data. Kinetic magnetic resonance imaging (kMRI) is an alternative method to conventional MRI, which allows evaluation spine in a more physiologic, weight-bearing position, and acquisition images flexion, extension, neutral alignment. kMRI has previously been used evaluate degeneration kinematics....
Previous studies by our group showed that nicotine delivered via a transdermal patch significantly enhanced posterior spinal fusion rates in rabbits. Nicotine patches provide steady serum level; there may be dose-dependent effect of on fusion. In an vitro cell culture model rabbit bone marrow–derived osteoblast-like cells, cells were exposed to different concentrations (0, 20, 40, 80 ng/mL and 10, 100, 250 μg/mL). Wells stained with alkaline phosphatase (ALP) staining kit determine ALP...
Study Design Retrospective review. Objective The purpose of this study was to determine the radiographic impact a transforaminal lumbar interbody fusion (TLIF) versus cantilever TLIF technique on segmental lordosis, coronal alignment, and disk height. Methods A retrospective review done all patients undergoing procedures from 2006 2011 by three spine surgeons. Traditional results were compared, outcomes assessed. Results One hundred one included in study. Patients procedure had significantly...
Extreme lateral interbody fusion (XLIF; NuVasive, Inc, San Diego, California) is a minimally invasive technique developed to avoid complications associated with traditional or anterior posterior approaches lumbar fusion. It uses direct lateral, retroperitoneal, transpsoas approach for placement of an cage. To date, no reports cage-related procedures revising XLIF have been published. This article describes case complication unique this procedure and the surgical used treat it. A 49-year-old...
Long-term outcome studies are frequently hindered by a decreasing frequency of patient follow-up with the treating surgeon over time. Whether this attrition represents “loss faith” in their index or realities geographically mobile society has never been assessed population patients undergoing spinal surgery. The purpose article is to determine which who have undergone prior surgery and develop new problems attempt spine surgeon. study design was survey. All seen at two university-based...
