PURPOSE: We aim to describe a mechanism of failure in magnetically controlled growth rods which are used for the correction of the early onset scoliosis. METHODS: This retrieval study involved nine magnetically controlled growth rods, of a single design, revised from five patients for metal staining, progression of scoliosis, swelling, fractured actuator pin, and final fusion. All the retrieved rods were radiographed and assessed macroscopically and microscopically for material loss...

BACKGROUND: Subspinous impingement of the anterior inferior iliac spine (AIIS) on the femoral head-neck junction is increasingly recognized as a source of hip impingement. A classification system of AIIS morphology has previously been proposed that correlates with reduced hip motion and may predispose patients to subspinous hip impingement. PURPOSE: To examine the morphological distribution of AIIS types in patients with and without diagnosed hip impingement and correlate AIIS morphology to intraoperative findings at the time of surgery...

BACKGROUND: Sarcopenia, a loss of skeletal muscle mass associated with aging, is a practical measure of frailty and has been previously identified as a predictor of outcomes in surgical cohorts including cancer resection and elderly patients. We hypothesized that sarcopenia, as measured by preoperative computerized tomography (CT) scan, predicts mortality and morbidity in emergent laparotomy. METHODS: Institutional American College of Surgeons National Surgical Quality Improvement Program data were queried for adult patients who underwent open emergency abdominal surgery between 2008 and 2013...

INTRODUCTION: Worldwide, hepatitis B virus, hepatitis C virus, and human immunodeficiency virus are major health problems. Healthcare workers are at risk of transmitting blood-borne viruses, and surgeons have a higher risk of exposure to blood and higher rates of percutaneous injury than other healthcare workers. Septoplasty is among the 3 most commonly performed otolaryngological surgeries worldwide. OBJECTIVE: To determine the seroprevalence of Hepatitis B surface antigen, Hepatitis C virus antibody, and Human Immunodeficiency Virus antibody in patients undergoing septoplasty with and without turbinate surgery under general anesthesia, and to determine if preoperative testing should be performed in such patients...

Oral and Maxillofacial Surgery (OMFS) remains an enigmatic specialty in Irish medicine and many students are unaware of its scope and the unique career pathway involved. We performed a multicentre cross-sectional study to identify their ability to identify the requirements for entry to specialty training year 3 (ST3) in OMFS, to assess their awareness of OMFS surgeons, and their general awareness of, and exposure to, the specialty. Data were collected through an electronic questionnaire. Participants were asked to select the most suitable surgical specialty to treat a number of common conditions in the head and neck, and to choose the requirements they deemed essential for specialist training...

Although magnetic resonance imaging (MRI) has been increasingly used as a diagnostic tool for cervical spine injuries in canines, a comprehensive normal MRI anatomy of the canine cervical spine muscles is lacking. Therefore, the purpose of this study was to build a magnetic resonance imaging atlas of the normal cross sectional anatomy of the muscles of the canine cervical spine. MRI scans were performed on a canine cadaver using a combination of T1 and T2-weighted images in the transverse, sagittal and dorsal planes acquired at a slice thickness of 1mm...

PURPOSE: Circumportal pancreas is a rare congenital pancreatic anomaly with encasement of the portal vein and/or the superior mesenteric vein by pancreatic tissue. It is often overlooked on cross-sectional imaging studies and can be encountered during pancreatic surgery. Pancreatic head resection with circumportal pancreas is technically difficult and bears an increased risk of postoperative pancreatic fistula. MATERIALS AND METHODS: A retrospective chart review of our data base for all patients who had undergone pancreatic head resection between 2004 and 2015 was performed...

BACKGROUND: Indications for performing a prophylactic central neck dissection (pCND) in papillary thyroid cancer (PTC) remain controversial. It is unclear how identification of lymph node (LN) metastases should impact the decision to treat with radioactive iodine (RAI). The goals of this study were to identify indications for performing pCND and identify factors that predict the use of adjuvant RAI. METHODS: This was a population based cross-sectional analysis. A prospectively collected database identified 594 patients who underwent total thyroidectomy +/- CND...

A variety of surgical procedures exist for repair of both traumatic and degenerative osseous and soft-tissue pathologic conditions involving the foot and ankle. It is necessary for the radiologist to be familiar with these surgical procedures, so as to assess structural integrity, evaluate for complicating features, and avoid diagnostic pitfalls. Adequate interpretation of postoperative changes often requires access to surgical documentation to evaluate not only the surgery itself but the expected timeline for resolution of normal postoperative changes versus progressive disease...
