In Brief Study Design. Retrospective study. Objective. To report on the technique and results of posterior vertebral column resection (PVCR) for severe rigid scoliosis. Summary Background Data. The treatment scoliosis is a demanding surgical challenge. Conventional procedures such as combined anteroposterior instrumentation enable limited correction. scoliosis, better option accomplishing translation spinal column. PVCR performed through single approach. Methods. A total 16 patients with...

In Brief Study Design. Radiographic analysis was performed retrospectively. Outcomes and complications were collected prospectively. Objectives. To assess after posterior fusion instrumentation for degenerative lumbar scoliosis, to determine risk factors of complications, analyze the clinical outcomes surgery. Summary Background Data. The scoliosis surgery have reported be high. Risk developing are unknown. Methods. Forty-seven patients (average age, 66.6 years; range, 48–83 years) with...

Retrospective study.To evaluate outcomes of selective thoracic fusion with segmental pedicle screw fixation in idiopathic scoliosis a minimum 5-year follow-up.Segmental has been proven to enable true control and greater correction both coronal sagittal planes scoliosis. However, there is no long-term study scoliosis.Two hundred three patients 236 curves subject were analyzed. Mean patient age at the time operation was 13.8 years (range: 8.9-18).The preoperative curve 51 +/- 12 degrees...

Study Design Thirty-nine adults and five children with active spinal tuberculosis resulting kyphosis of the dorsal lumbar spine who had combined posterior instrumentation anterior interbody fusion were observed to determine whether corrected deformity could be maintained until solid fusion. Objective To evaluate effectiveness two-stage procedure for treating due tuberculosis. Summary Background Data Until 1970, all methods treatment, tended increase during therapy. Most patients treated...

Retrospective study.To report the results and technique of posterior vertebral column resection (PVCR) in fixed lumbosacral deformity.Fixed deformity has gross imbalance as well progressive compensatory thoracolumbar because absence a mobile spine caudally. There is no consensus surgical treatment deformity. Fixed can be managed by PVCR, which not only corrects but also restores trunk balance translation spinal column.Twenty-five consecutive patients subjected to PVCR were reviewed after...

Retrospective study.To evaluate the incidence and risk factors of complications following posterior vertebral resection (PVR) for spinal deformity.A review 233 patients treated with PVR at one institution over a nine-year period (1997 to 2005) was performed. The average age 33.5 years. Complications were assessed in terms surgical techniques (posterior column [PVCR] decancellation osteotomy) etiologies deformity.Local kyphosis corrected from 51.4° 2.7°, thoracic scoliosis 63.9° 24.5° (62.6%...

Retrospective study.To evaluate the effect and outcome of thoracoplasty in conjunction with pedicle screw instrumentation treatment thoracic adolescent idiopathic scoliosis (AIS).Some spine surgeons recently think more correction hump deformity using screws without thoracoplasty. Although has been conventional rib hump, there are few papers about results concomitant thoracoplasty.Eighty-seven patients AIS (mean age, 14.4 years) treated by were retrospectively analyzed after a minimum...

A biomechanical study.To compare, in cervical vertebrae (C3-C6), the pullout strengths of pedicle screws and lateral mass after both types screw had been subjected to a period cyclic loading 2 planes.In posterior subaxial fixation systems, are usually inserted into mass. As an alternative fixation, became popular 1990s was first used for lower spine trauma cases. However, it is controversial as whether upper-middle offers much security compared with fixation.For each 32 vertebrae, 1 side...

Objective: The transcriptional profile of gastric epithelial cell lines cocultured with Helicobacter pylori and the global gene expression whole mucosa has been described previously. We aimed to overcome limitations previous studies by determining effects H eradication on transcriptome purified human epithelium using each patient as their own control. Design: Laser capture microdissection (LCM) was used extract mRNA from paraffin-embedded antral 10 patients peptic ulcer disease, before after...

A retrospective comparative study.To evaluate the shoulder balance resulting from correction of double thoracic adolescent idiopathic scoliosis (AIS) comparing rod derotation (RD) with direct vertebral rotation (DVR) and RD only after pedicle screw instrumentations.This is first report on effect DVR using segmental instrumentation in treatment AIS minimum 5-year follow-up.Patients (n = 57) were treated by fusing both curves (n=35), or (n=22) methods retrospectively studied a 5 years...

Acute airway obstruction (AAO) after anterior cervical fusion (ACF) can be caused by postoperative retropharyngeal hematoma, which requires urgent recognition and treatment. However, the causes, evaluation, appropriate treatment of this complication are not clearly defined. The purpose retrospective review a prospective database was to investigate etiologic factors related development AAO due hematoma ACF formulate prevention guidelines. Cervical spinal cases treated at our academic...

Study Design A retrospective study. Purpose To determine the exact distal fusion level in management of thoracolumbar/lumbar adolescent idiopathic scoliosis (TL/L AIS) using pedicle screw instrumentation (PSI). Overview Literature The selection remains controversial TL/L AIS. Methods Radiographic parameters 66 AIS patients were analyzed. grouped according to level; L3 group (fusion L3, n=58) and L4 L4, n=8). was subdivided into L3A (L3 crosses mid-sacral line with rotation less than grade...

We investigated the results of delirium which developed after total knee arthroplasty (TKA) and risk factors for in patients who are older than 65 years. From March 2008 to 2012, we performed a retrospective study on 296 knees 265 were treated with TKA. They divided into two groups: 216 without 49 diagnosed by psychiatry. analyzed three categories: First, preoperative including gender, age, body mass index (BMI), clinical functional joint score (Knee Society Knee Score Function Score) number...

Design: This study is a radiographic analysis. Objective: To compare the fusion rates after anterior cervical discectomy and (ACDF) using x-rays versus computerized tomography (CT). Background: Although status may be obvious when evaluating ACDFs performed in remote past, determining presence of solid at earlier time points ACDF often ambiguous but necessary part practice. Commonly used tools include radiographs CT scans. Currently, there no gold standard imaging modality to determine...
