STUDY DESIGN Retrospective study. OBJECTIVE To determine if C1 lateral mass screws could be safely inserted without the use of fluoroscopy. SUMMARY OF BACKGROUND DATA Standard surgical technique for C1 lateral mass screw placement uses intraoperative fluoroscopy. However, intraoperative fluoroscopy is time consuming, cumbersome, and exposes both the(More)
STUDY DESIGN Prospective clinical trial. OBJECTIVE The goal of this prospective study was to assess the reliability of plain radiographs, computed tomography (CT), and magnetic resonance imaging (MRI) to detect a pseudarthrosis after an anterior cervical fusion compared with intraoperative exploration. SUMMARY OF BACKGROUND DATA Although anterior(More)
STUDY DESIGN Retrospective study. PURPOSE To investigate safety profile of open door laminoplasty plates. OVERVIEW OF LITERATURE Few reports have documented potential complications related to the use of cervical laminoplasty plates. METHODS Records and radiographs of consecutive plated laminoplasty patients of one academic surgeon were analyzed. Group(More)
Pelvic fixation via iliac screws is a crucial technique in stabilizing metastatic lumbosacral deformity. MIS iliac screw fixation avoids complications of an open approach and is a viable palliative option in treating patients with painful instability and advanced disease, unsuited for major reconstruction. In this paper we describe the use of MIS iliac(More)
It is necessary to assess coronal Cobb angle in the diagnosis and treatment of patients with adult degenerative scoliosis (ADS). But as most ADS patients are elderly patients who are difficult or unable to stand upright without assistance, it is difficult to obtain standing posteroanterior X-ray radiographs. Whether it is possible to use Cobb angle obtained(More)
STUDY DESIGN Consecutive case series. OBJECTIVE The purpose of this study was to analyze the pseudarthrosis rate in a large series of recombinant human bone morphogenetic protein-2 (rhBMP-2) augmented multilevel (> or =3 levels) anterior cervical fusions. SUMMARY OF BACKGROUND DATA The reported pseudarthrosis rate following anterior cervical fusion(More)
Traumatic spondylolisthesis of the lumbar spine is uncommon and can result in canal narrowing and spinal cord injury. Early decompression promotes recovery of neurological function. We report 3 such cases: one in the lumbosacral joint and 2 in the lumbar spine. The former patient had an open fracture-dislocation and underwent (delayed) posterior(More)
STUDY DESIGN Retrospective review of prospectively collected data. OBJECTIVE To identify the cause of failed open-door laminoplasty and to describe the surgical strategies for revision surgery. SUMMARY OF BACKGROUND DATA Although laminoplasty has become popular, few articles have addressed the cause of failed cervical laminoplasty requiring revision(More)
STUDY DESIGN A retrospective study. OBJECTIVE The aim of this study was to detect risk factors for Adding-on after posterior correction surgery in patients with Lenke 1 or 2 AIS, and to explore whether Adding-on Index could be used to predict Adding-on effectively. SUMMARY OF BACKGROUND DATA Adding-on phenomenon is a common complication in Lenke 1 or 2(More)
