In the present work, an image processing technique that automatically detects and analyses cracks in digital of concrete surfaces is proposed. The automates measurement crack characteristics including width, length, orientation pattern. proposed technique, a morphological was applied to correct non-uniform brightness background, enhanced binarisation shape analysis were used improve detection performance; furthermore, detailed algorithms calculate artificial neural network recognise patterns...
In Brief Study Design. Retrospective study of the difference heterotopic ossification (HO) occurrence according to 3 different types prosthesis. Objective. This was designed investigate HO type Summary Background Data. is defined as formation bone outside skeletal system. Reported rate in cervical artificial disc replacement (ADR) unexpectedly high and varied. But influencing factors ADR have not been elucidated well. The prosthesis-related for making were investigated this study. Methods. A...
Pelvic reconstruction after sacral resection is challenging in terms of anatomical complexity, excessive loadbearing, and wide defects.Nevertheless, the technological development 3D-printed implants enables us to overcome these difficulties.Here, we present a case osteosarcoma surgically treated with hemisacrectomy using implant.The implant was printed as customized titanium prosthesis from 3D real-sized patient's CT images.It consisted mostly porous mesh incorporated dense strut.After...
We report a series of epidural hematomas which cause neurologic deterioration after spinal surgery, and have taken risk factors prognostic into consideration.We retrospectively reviewed the database 3720 cases spine operation in single institute over 7 years (1998 April-2005 July).Nine patients who demonstrated surgery required surgical decompression were identified.Factors postulated to increase postoperative hematoma improve outcome investigated.The incidence was 0.24%.Operation sites...
A prospective analysis.The purpose of this study was to compare the clinical and radiologic outcomes cervical artificial disc replacement (C-ADR) combined with anterior discectomy fusion (ACDF) 2-level ACDF in patients disease.Adjacent segment degeneration is a long-term complication ACDF, estimated affect 25% within 10 years initial surgery. Two-level leads substantially greater increase intradiscal pressure than one-level fusion. It has been demonstrated that C-ADR maintains motion at...
The goal of this study was to determine the relationship between cervical spine sagittal alignment and clinical outcomes after laminoplasty in patients with ossification posterior longitudinal ligament (OPLL).Fifty consecutive who underwent a for OPLL January 2012 2013 were followed up at least 1 year analyzed study. Standing plain radiographs spine, CT (midsagittal view), MRI (T2-weighted view) obtained (anteroposterior, lateral, flexion, extension) pre- postoperatively. Cervical assessed...
Abstract BACKGROUND Spinal cord glioma grade IV is a rare, diffuse midline glioma. H3 K27M-mutant was classified in different entity the 2016 World Health Organization (WHO) classification recently. No reports about prognosis of spinal are available yet. OBJECTIVE To analyze prognostic factors for IV. METHODS Twenty-five patients with who underwent surgery single institute were selected. All histologically confirmed as glioblastoma or “diffuse K27M-mutant” by WHO central nervous system...
The aim of this study is to provide basic experimental data help prevent environmental pollution and pursue resource recycling by examining the use waste oyster shells (OS) as concrete aggregate. possibilities manufacturing into lightweight hollow blocks are also examined. physicochemical characteristics OS analysed materials mechanical according age evaluated for fresh hardened concretes. New chemical reactions abnormal substances from mixing found be absent. Although problems in strength...
Any persistent degree of cognitive impairment in older adults is a concern as it can progress to dementia. This study aimed determine the incidence and risk factors for early postoperative dysfunction (POCD) elderly patients undergoing spine surgery.
