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...

Lumbar spinal fusions have been performed for nearly a century for a variety of spinal conditions and include posterior/posterolateral and anterior lumbar interbody fusions. Traditionally, the ability to achieve adequate exposure to perform these procedures required an open surgical approach; however, the advent of newer techniques and technology, combined with an improved understanding of surg...

Generally, patients with severe burst fractures, instability, or neurological deficits require surgical treatment. In most cases, circumferential reconstruction is performed. Surgical methods for three-column include anterior, lateral, and posterior approaches. cases involving an anterior lateral approach, collaboration general thoracic surgeons may be necessary because the adjacent anatomical ...

background & importance: spinal deformity is one of the most common disorders among the vertebral diseases that results from unnatural curvatures of spine, such as scoliosis and kyphosis. spinal fusion surgery used most commonly to treat certain types of spinal deformity. here in, we report the efficacy of posterior spinal fusion accompanied by instrumentation in patients with the limitations o...

abstract objective: to present the changes in projected thoracic hypokyphosis and the behavior of lumbar lordosis within and below the fusion and to compare these changes between the harrington rod (hr) and posterior multisegmented hook instrumentation. methods: 178 patients with idiopathic scoliosis, who had undergone posterior spinal fusion with harrington technique (106 patients) or multiseg...

 Abstract Objective: To present the changes in projected thoracic hypokyphosis and the behavior of lumbar lordosis within and below the fusion and to compare these changes between the Harrington rod (HR) and posterior multisegmented hook instrumentation. Methods: 178 patients with idiopathic scoliosis, who had undergone posterior spinal fusion with Harrington technique (106 patients) or multise...

Degenerative disc and facet joint disease of the lumbar spine is common in the ageing population, and is one of the most frequent causes of disability. Lumbar spondylosis may result in mechanical back pain, radicular and claudicant symptoms, reduced mobility and poor quality of life. Surgical interbody fusion of degenerative levels is an effective treatment option to stabilize the painful motio...

BACKGROUND Although some investigators believe that the rate of postoperative instability is low after lumbar spinal stenosis surgery, the majority believe that postoperative instability usually develops. Decompression alone and decompression with fusion have been widely used for years in the surgical treatment of lumbar spinal stenosis. Nevertheless, in recent years several biomechanical studi...

Background and Aim: Degenerative lumbar scoliosis is a spinal deformity resulting from advanced disc degeneration and facet arthropathy. Given the inconclusive available literature and lack of high-quality data supporting the role of minimally invasive surgical management of degenerative lumbar scoliosis, this review intends to highlight and compare the various viable minimally invasive surgica...
