Filter by:This study has been added as a sub study to the Simulation Training for Emergency Department Imaging 2 study (ClinicalTrials.gov ID NCT05427838). This work aims to evaluate the impact of an Artificial Intelligence (AI)-enhanced algorithm called Boneview on the diagnostic accuracy of clinicians in the detection of fractures on plain XR (X-Ray). The study will create a dataset of 500 plain X-Rays involving standard images of all bones other than the skull and cervical spine, with 50% normal cases and 50% containing fractures. A reference 'ground truth' for each image to confirm the presence or absence of a fracture will be established by a senior radiologist panel. This dataset will then be inferenced by the Gleamer Boneview algorithm to identify fractures. Performance of the algorithm will be compared against the reference standard. The study will then undertake a Multiple-Reader Multiple-Case study in which clinicians interpret all images without AI and then subsequently with access to the output of the AI algorithm. 18 clinicians will be recruited as readers with 3 from each of six distinct clinical groups: Emergency Medicine, Trauma and Orthopedic Surgery, Emergency Nurse Practitioners, Physiotherapy, Radiology and Radiographers, with three levels of seniority in each group. Changes in reporting accuracy (sensitivity, specificity), confidence, and speed of readers in two sessions will be compared. The results will be analyzed in a pooled analysis for all readers as well as for the following subgroups: Clinical role, Level of seniority, Pathological finding, Difficulty of image. The study will demonstrate the impact of an AI interpretation as compared with interpretation by clinicians, and as compared with clinicians using the AI as an adjunct to their interpretation. The study will represent a range of professional backgrounds and levels of experience among the clinical element. The study will use plain film x-rays that will represent a range of anatomical views and pathological presentations, however x-rays will present equal numbers of pathological and non-pathological x-rays, giving equal weight to assessment of specificity and sensitivity. Ethics approval has already been granted, and the study will be disseminated through publication in peer-reviewed journals and presentation at relevant conferences.
A 10-year follow up of a fusion of two earlier published randomized controlled trials. 203 patients with displaced distal radius fractures were randomized to surgery with a volar locking plate or external fixation.
Orthopedic injuries comprise more than 10% of ED visits in children and 25 to 50% of children will sustain a fracture before age 16 years. Distal radius fractures account for 20-32% of fractures in children, making them the most common fracture type. Between 20 and 40% of extremity fractures in children require a closed reduction, often necessitating procedural sedation and analgesia (PSA). Intravenous (IV) ketamine is the most commonly used sedative agent used to perform a closed reduction. However, children rate IV insertion as the most painful hospital experience, second only to the injury itself. IV insertion can be more technically difficult in children because of smaller veins and lack of cooperation, often leading to multiple IV attempts. A combination of intranasal (IN) dexmedetomidine plus ketamine (IN Ketodex) may provide effective sedation for children undergoing a closed reduction without the distress and pain related to IV insertion. A less painful experience has been found to correlate with child satisfaction which may reduce caregiver anxiety and improve the therapeutic relationship with the health care team. This study is a multi-centre, two-arm, randomized, blinded, controlled, non-inferiority trial designed to test the hypothesis that IN Ketodex is non-inferior to intravenous (IV) ketamine with respect to depth of sedation as measured using the Pediatrics Sedation State Scale (PSSS).
Leg length discrepancies following total hip arthroplasty have been associated with nerve palsies, gait abnormalities, and lower back pain. Leg length discrepancies are related to poorer functional outcomes and patient dissatisfaction. Failure to restore femoral offset following total hip arthroplasty has been linked to decreased range of motion and abductor muscle strength, impingement, limping, higher dislocation rates, increased polyethylene wear, and loosening of implants. Computer navigation has shown to improve the accuracy of leg length and hip offset during total hip arthroplasty. The investigators research objective is to prove the accuracy of the Intellijoint HIP™ system for determining leg length and hip offset. The investigators hypothesis was that Intellijoint HIP™, an imageless intraoperative intelligent instrument, could improve the accuracy of leg length and hip offset during primary total hip arthroplasty. The investigators plan to study this hypothesis in humans by comparing the leg length and hip offset discrepancies produced with Intellijoint HIP™ to the standard at the investigators institution, which is a pin and outrigger system.
Hypothesis There is no difference in the incidence of pin tract infection and pin loosening in case of lower extremity external fixators when self-drilling schanz pins are used with or without pre-drilling. Primary Objective The primary objective is to determine whether pre-drilling holes for external fixation pin insertion is superior to not pre-drilling holes for external fixation pin insertion in regards to the incidence of pin tract infection and pin loosening. Secondary Objective If any difference is found between the two techniques then, we will quantify and qualify those differences. The incidence of pin site infection and pin loosening in general will be determined and will also be stratified for site and size of pin. An attempt to identify risk factors for pin site infection will be made by observing the effect of secondary prognostic factors like mode of injury, diabetes, smoking, compartment syndrome, peripheral vascular disease, neurovascular injury. Interobserver reliability of the grading system for pin infection will also be determined.
