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   background: to evaluate proximal junctional segment changes in adolescent idiopathic scoliosis(ais) the posterior spinal fusion and also instrumentation also and finding of probable risk factors, were all considered in this study.   methods: we retrospectively reviewed radiographs of 121 consecutive patients who underwent posterior spinal fusion for ais from t3 or below, with a mean ...

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...

 Abstract Background: Correction of severe kyphosis is a challenging operation in spinal surgery. A two stage operation has been commonly used: anterior release and decompression followed by posterior correction and fusion. We describe the posterior vertebral osteotomy technique for correction of severe and rigid kyphosis through posterior-only approach. Methods: Twelve patients (six male and s...

background: controlling the hemodynamic situation of patients who have spinal operation is of prime importance, and maintaining the heart rate and blood pressure in normal or low- normal levels in these patients can reduce their bleeding loss. one of the commonly used drugs for this purpose is remifentanil. another sedative-hypnotic-analgesic drug, with acceptable effects is dexmedetomidine. th...
