Objectives: In MPFL reconstruction surgery, achieving perfect placement of the femoral tunnel intraoperatively is difficult. An understanding effects malpositioning has on graft isometry crucial to minimizing instability or overconstraint which leads anterior knee pain, increased patellofemoral contact pressures, failure. The purpose this study was identify differences in with malpositioning, s...

AbstractStatement of problem Malpositioning implants is one the main factors leading to hard- and soft-tissue deficiencies. Whether static computer-guided implant placement increases accuracy prevents malpositioning unclear. Purpose The purpose this in vitro study was determine defined by trueness precision (according International Organization for Standardization 572...

BACKGROUND Minimal invasive surgery (MIS) has gained growing popularity in total hip arthroplasty (THA) but concerns exist regarding component malpositioning. The aim of the present study was to evaluate femoral and acetabular component positioning in primary cementless THA comparing a lateral to a MIS anterolateral approach. METHODS We evaluated 6 week postoperative radiographs of 52 hips wi...

Introduction: Adequate reconstruction of the skull base is the key to avoiding cerebrospinal fluid (CSF) leak following endonasal skull base surgery. The use of an endocranial “gasket” plug has been reported for this and is used in our institution. We present a simple refinement of the “gasket” technique using commonly available materials that helps ensure proper size and positioning of the gas...

Background. This review describes the peritoneal dialysis (PD) catheter implantation techniques for the treatment of PD. The PD catheter-related complications still cause significant morbidity and mortality, resulting in the necessity to switch to haemodialysis (HD) treatment. Methods. Several catheter insertion techniques, using an open surgical approach, laparoscopic and percutaneous techniqu...

This study investigated the safety and effectiveness of each type of central venous catheters (CVC) in patients with cancer. We prospectively enrolled patients with cancer who underwent catheterization involving a subclavian venous catheter (SVC), peripherally inserted central venous catheter (PICC), or chemo-port (CP) in our department. From March 2007 to March 2009, 116 patients underwent 179...

original article background and objectives: one type of electromagnetic fields, based on frequency range, is extremely low frequency (elf) fields. there are lots of reports about measuring elf- magnetic field (mf) in substations, power plants, cities, near high voltage power lines and etc. this study aimed to compare the difference between measurement of three-axis and single-axis probe mf mete...

INTRODUCTION Tapia's syndrome is a rare complication of recurrent laryngeal and hypoglossal nerve paralysis due to anesthetic airway mismanagement or malpositioning of the patient's head during surgery. CASE REPORT Here we present a case of Tapia's syndrome in a 22-year-old male after corrective jaw surgery under general anesthesia, with a long period of recovery, related to airway management...

We report a challenging case of a 81-year-old male with history of severe calcific aortic valve stenosis and aneurysmal membranous interventricular septum. The presence of anomalies in the sub-annular area can lead to valve malpositioning and its consequences. transcatheter aortic valve implantation (TAVR) in patients with aneurysm of the perimembranous interventricular septum extending into th...
