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...
روبات های راه رونده به عنوان یک موضوع مورد علاقه مراکز تحقیقاتی دنیا و نیز مورد استفاده در صنایع مختلف، دارای رواج و اهمیت خاصی بوده و استفاده از این روبات ها در موارد و مأموریت های خاص غیر قابل جایگزینی می باشد. در میان این خانواده روبات ها، روبات های دو پا به عنوان یک روبات دارای شباهت زیاد به انسان دارای جایگاه خاصی می باشد. از مشخصات بارز این روبات ها، درجات آزادی و انعطاف بالا و ناپایداری ...
background : episiotomy is the incision of perineum made to facilitate childbirth. here are the two types of episiotomy: median and mediolateral. considering the important role of incision characteristics such as length, angle and distance of initiation point from midperineum line in prevention of perineal rupture and reduction of further complications, this study investigated the comparison ep...
Backgroundm: Scapulohumeral rhythm (SHR) has been established as the kinematic hallmark indicating motion of the shoulder joint. Numerous studies have investigated the effect of different factors on SHR. The purpose of the present study was to determine the scapular upward rotation and scapulohumeral rhythm ratio among frontal, sagittal, and scapular planes in different humeral abduction ang...
BACKGROUND Radiography, typically the first-line imaging study for diagnosis of craniosynostosis, exposes infants to ionizing radiation. We aimed to compare the accuracy of cranial ultrasound (CUS) with radiography for the diagnosis or exclusion of craniosynostosis. METHODS Children aged 0 to 12 months who were assessed for craniosynostosis during 2011-2013 by using 4-view skull radiography a...
Background: Sagittal imbalance is known as the main radiographic driver of disability in adult spinal deformity (ASD).In this study, the association of radiological spinopelvic parameters and clinical outcomes was evaluated following thecorrective surgery of sagittal imbalance, in order to explore the predictive ability of each parameter.Methods: A total of 23 patients, who underwent corrective...
PURPOSE Three-dimensional (3D) effects of the single plane osteotomies of the proximal femur are compared and analyzed by the trigonometric method. MATERIALS AND METHODS The shape of proximal femur was simplified as a bent line. The bent line is the continuation of the three points-the center of the femoral head, the center of femoral neck at the base, and the center of the femoral shaft. The...
INTRODUCTION Determining the proper angle for inserting central venous catheter (CV line) is of great importance for decreasing the complications and increasing success rate. The present study was designed to determine the proper angle of needle insertion for internal jugular vein catheterization. METHODS In the present case series study, candidate patients for catheterization of the right in...
Study Type Retrospective review. Introduction Sagittal imbalance has been associated with lower health-related quality of life outcomes, and restoration of imbalance is associated with improved outcomes.123 The long constructs used in adult spinal deformity have potential consequences such as proximal junctional kyphosis (PJK). Clinically, the development of PJK may not be as important as failu...
