surgery on the skeleton frequently requires harvesting of autogenous bone graft from the pelvis, but this procedure often is complicated by problems. the purpose of this retrospective, comparative descriptive study was to compare the efficacy of metal-derived bioactive glass (novabone) versus autogenous iliac crest bone graft in adolescent idiopathic scoliosis surgery. the study was carried out...
background: remifentanil is a narcotic drug used in anaesthesia for establishment of hemodynamic stability. the purpose of this study was to compare the effects of remifentanil and fentanyl on urine excretion. methods: in a randomized clinical trial, 60 patients, who were candidates for elective surgery for lumbar posterior spinal fusion, were divided randomly into two groups of 30 as remifenta...
normal 0 false false false en-us x-none fa microsoftinternetexplorer4 in this paper, a fully discretized bio-fidelity simulation model for bio-mechanical (kinematic) analysis of scoliosis for various patients was developed to analyze forces on vertebrae, loads acting on the intervertebral disc, corresponding angles between vertebrae, and tension in the spine muscles during lateral bending. it w...
Background: Scoliosis is one of the most common spinal deformities with subsequent decrease in pulmonary function. The effects of surgical correction on the pulmonary function of patients with adolescent idiopathic scoliosis are controversial. The purpose of the present study was to compare the postoperative pulmonary function changes in different surgical approaches chosen for its correction. ...
Background and purpose: Bone fusion is a dynamic process and availability of calcium and balance of vitamin D can be effective in post spinal cord fusion. There are contradictory results on this issue, so, we decided to compare the effect of administration of vitamin D and alendronate on lumbosacral vertebral fusion in patients undergoing posterior spinal fusion surgery. Materials and methods:...
Lumbar spinal fusions have been performed for spinal stability, pain relief and improved function in spinal stenosis, scoliosis, spinal fractures, infectious conditions and other lumbar spinal problems. The success of lumbar spinal fusion depends on multifactors, such as types of bone graft materials, levels and numbers of fusion, spinal instrumentation, electrical stimulation, smoking and some...
Cell membrane has a critical and vital role in functioning and existence of nerve cells that form central nervous system (CNS) in mammals. Disruption of nerve membrane that normally occurs following an accident injuring spinal cord is known to be the major cause of paralysis. In most occasions, spinal cord injuries are not leading to complete cut in spinal cord fibers but are known to cause cru...
Instrumented spinal fusion has become one of the most common surgeries for patients with various spinal disorders. Only few studies have reported subsequent vertebral compression fractures (VCFs) after instrumented spinal fusion. The purpose of this study was to evaluate the risk of new VCFs in patients undergoing instrumented spinal fusion.We obtained claims data from the National Health Insur...
