INTRODUCTION: Pedicle screw (PS) constructs allow for better curve correction in the coronal plane as well as in the axial plane in patients with adolescent idiopathic scoliosis (AIS)[1, 2]. However, reduction of physiological kyphosis of the thoracic spine has been one of the problems associated with the PS constructs [3]. The hypothesis for the hypokyphogenesis is that the direct vertebral de...

We have performed a detailed morphometric analysis of the length and anatomic routes of the greater palatine canal (GPC) and a systematic review of the literature on the anatomy of the GPC with the aim of informing dentists, maxillofacial surgeons, otorhinolaryngologists and other specialists performing procedures in the area of the GPC. In total, we analysed 1,500 archived adult head computed ...

To understand brain injuries better, the mechanical properties of brain tissue have been studied for 50 years; however, no universally accepted data set exists. The variation in material properties reported may be caused by differences in testing methods and protocols used. An overview of studies on the mechanical properties of brain tissue is given, focusing on testing methods. Moreover, the i...

Magnetic field fluctuations at high heliographic latitudes are discussed in terms of the latitude and radial dependence of their variances, as observed by the Ulysses spacecraft. The increased level of transverse fluctuations in fast solar wind flows from the polar coronal holes is similar to that found in high spce.d streams near the ecliptic. However, continuous observations in the fast solar...

Conventional osteotomy used for the correction of deformity is performed out of the plane of deformity creating a wedge either opening or closing when the deformity is corrected. Deformity that is a combination of rotation and angulation exists in a single plane that is oblique to the coronal, sagittal and axial planes depending on the magnitude of deformity measured in each plane. Accurate pla...

CONTEXT AND AIMS The purpose of this study was to compare and evaluate the shaping ability of ProTaper (PT) and Self-Adjusting File (SAF) system using cone-beam computed tomography (CBCT) to assess their performance in oval-shaped root canals. MATERIALS AND METHODS Sixty-two mandibular premolars with single oval canals were divided into two experimental groups (n = 31) according to the system...

Introduction Computer-assisted navigation systems have been explored in total hip arthroplasty (THA) to improve component positioning. While these systems traditionally rely on anterior pelvic plane registration, variances in soft tissue thickness overlying anatomical landmarks can lead to registration error, and the supine coronal plane has instead been proposed. The purpose of this study was ...

UNLABELLED In the supraclavicular lateral paravascular approach for brachial plexus regional anesthesia by Moorthy et al. (Moorthy's block), the patient is supine with the ipsilateral shoulder displaced anteriorly 5-8 cm. The needle direction is precisely defined in the coronal plane (using a Doppler flowprobe) but not in the sagittal plane. We sought to determine whether the block could be sim...

OBJECTIVE A high prevalence of poor standing posture among elementary schoolchildren indicates the need for the introduction of school-based interventions for improvement of postural alignments. For assessing the effect of intervention programs, reliable quantitative measures of standing posture should be used. Therefore, the purpose of this study was to examine the reliability of a photographi...

PURPOSE To calculate the indirect costs of Patient Specific Instruments (PSI) based on an opportunity cost, cost of efforts and a supply chain cost model to compare PSI for value with conventional total knee arthroplasty (TKA). METHODS In 81 patients the total (direct+indirect) cost of PSI-assisted TKA was compared with conventional TKA. Surgical times and coronal mechanical alignment were me...
