UNLABELLED A physiologic sagittal alignment of the spine with lumbar lordosis and thoracic kyphosis is the most stable position of the spine, while in patients with Idiopathic Scoliosis (IS) the sagittal profile of the spine is flattened or inversed. It has been shown that a correction of the sagittal profile also corrects coronal plane deformity in patients with IS. Therefore sagittal correcti...

Introduction: Optimal coronal and sagittal component positioning is important in achieving a successful outcome following total knee arthroplasty (TKA). Modalities to determine post-operative alignment include plain radiography and computer tomography (CT) imaging. This study aims to determine the accuracy and reliability of plain radiographs in measuring coronal and sagittal alignment followin...

For opening wedge high tibial osteotomy (OWHTO), it is recommended that the osteotomy line is parallel to the medial tibial posterior slope (TPS) in the sagittal view and that the alignments are simultaneously controlled in the coronal and sagittal views. Here combined computed tomography (CT)-based and image-free navigation systems were used for intraoperative reference during OWHTO. Using the...

This study evaluated the mechanical performance of teardrop-shaped loops and teardrop-shaped loops with helix used in orthodontic space closure. Sixty retraction loops made with 0.019" x 0.025" stainless steel (SS) and beta-titanium (BT) wires were used. They were attached to a testing machine to measure the magnitudes of the sagittal force and the load-deflection ratio necessary for 1 mm, 2 mm...

CONTEXT Swenson's pull-through is one of the standard operations for the treatment of children with Hirschsprung's disease. Complications arising from the operation are difficult to treat because of fibrosis in the pelvis. The posterior sagittal approach may be a safer alternative. AIMS The aim of this paper is to highlight our experience with the use of the posterior sagittal trans-sphincter...

PURPOSE The purpose of the study was to identify the femoral tunnel orientation that consistently results in a tunnel length of more than 35 mm in anterior cruciate ligament reconstruction. MATERIALS AND METHODS Computed tomography (CT) scans were obtained from 30 patients who did not have any pathology in the distal femur. Virtual tunnels were marked on 3D (3-dimensional) reconstructed CT im...
