Study Design A retrospective comparative study. Purpose To compare perioperative medical complications after posterior approach spinal instrumentation surgery for osteoporotic vertebral collapse (OVC) between patients with primary osteoporosis and those with secondary osteoporosis. Overview of Literature With increased aging of society, the demand for instrumentation surgery for an osteopor...

The effects of treatment of scoliosis in neurofibromatosis type 1 are less satisfactory than other scoliotic types due to the particular pathogenesis and clinical characteristics. Surgical treatment usually included 360 degrees fusion with instrumentation, but optimal strategies are different according to the degree of deformity. High incidence of pseudarthrosis, extensive bleeding and curve pr...

STUDY DESIGN A retrospective-matched cohort study. OBJECTIVE To assess the correction of the adolescent idiopathic scoliosis (AIS) deformity in three dimensions, comparing consecutive and interval pedicle screw (PS) instrumentation techniques. SUMMARY OF BACKGROUND DATA The number of the sites that should be implanted with pedicle screws in AIS surgery is controversial. Coronal and sagittal...

OBJECTIVES To investigate the clinical manifestation and surgical outcome of spinal osteoblastoma. METHODS From June 2006 to July 2011, 18 patients with spinal osteoblastoma treated surgically were analyzed retrospectively. There were 11 males and 7 females with an average age of 27.5 years（range, 16-38 years). The tumors were located at C5 in 7, C6 in 6, C7 in 3, C6-T1 1 in 1 and T11 in 1. B...

The purpose of this study was to determine the efficacy of stage I posterior osteotomy and instrumentation followed by stage II anterior debridement and bone grafting in patients with lumbar spinal tuberculosis (TB) with severe kyphosis. The records of patients with lumbar spinal TB and severe kyphosis treated with 2-stage surgery at our hospital from 2005 to 2010 were retrospectively reviewed....

INTRODUCTION Obstruction of the third part of the duodenum by the superior mesenteric artery (SMA) can occur following surgical correction of scoliosis. The condition most commonly occurs in significantly underweight patients with severe deformities during the first few days to a week following spinal surgery. CASE PRESENTATION We present the atypical case of a patient with normal body habitu...

Understandably describe historical and current spinal deformity classifications. Spinal deformities can be divided into three main categories: congenital, idiopathic, secondary deformities. Secondary is by far the largest group. Congenital are generally seen in very early ages may accompanied neural with systemic organ pathologies. Different classification systems based on clinical radiological...
