Filter by:The purpose of this study is to create an institutional and population-based registry of Hip fracture in the elderly with a prospective survey based on epidemiological data, risk factors, diagnosis, prognosis, treatment, monitoring and survival.
This study consists of a retrospective and a prospective part. For each part and in each of 5 clinics, one intraoperative postimplant image (lateral view) of 25 patients with pertrochanteric fractures will be assessed by 5 surgeons per clinic. There are two assessments in the retrospective part. a) before an educational intervention, b) after the educational intervention. The evaluated images at these two timepoints are identical. In the prospective part, the surgeons apply their new knowledge from the educational intervention. They perform the positioning of the patient during the intraoperative fluoroscopy and record the image according to the teaching material. One postimplant image of each patient will be used for the evaluation. At all three timepoints of image assessment, a questionnaire with the same set of 7 criteria (Q1-Q7) for assessing the radiographs is used. The criteria refer to the content of the educational material.
The aim of this cohort study is to precisely measure patients' exposure to gonadal radiation during orthopaedic trauma surgery involving the acetabulum, pelvis, hip, and femur, and to apply these findings to a previously described and validated formula to determine the increased risk of future adverse health effects to the reproductive organs. The investigators null hypothesis is standard of care use of x-ray fluoroscopy during treatment of pelvis, hip, and femur fractures will not expose patients to a significant gonadal radiation load. Analysis of patients' intraoperative radiation doses by means of a previously validated formula will not display a significantly increased risk of adverse health events in the reproductive organs.
The main objective of the trial is to complete a double-blinded randomized controlled trial of a lumbar plexus block with the Shamrock technique versus the Lumbar Ultrasound Trident technique by estimating the time of performance of lumbar plexus blocks in healthy volunteers. Secondary objectives include a) estimates of number and depth of needle injections, distance of injection site from the midline, minimal electric nerve stimulation to trigger muscular response and the type of response, and volunteer discomfort during block injection, b) measurements of plasma lidocaine and mean arterial blood pressure, c) examinations of sensory block of the dermatomes T8-S3 and motor block of the femoral nerve, the obturator nerve, the hip abductor muscles, and the hamstring muscles, d) success rate of lumbar plexus block, e) perineural and epidural distribution of local anesthetics added contrast visualized on magnetic resonance imaging (MRI) scanning, and f) cost-effectiveness for the Shamrock technique versus the Lumbar Ultrasound Trident Technique for lumbar plexus block in healthy volunteers. The hypothesis is that the Shamrock technique is faster to perform than the Lumbar Ultrasound technique, and that the success rate of the Shamrock technique is equal to or higher than the Lumbar Ultrasound Trident technique.
Prolongation of the analgesic effect of a femoral nerve block from the present 15 hours to 24 hours in patients with hip fracture would have a major impact in order to provide better preoperative analgesia for this group. In other trials concerning other nerves then the femoral nerve the addition of Dexamethasone to the local anesthetics doubled the analgesic duration. No studies has investigated the effect of the addition of Dexamethasone to the femoral nerve block in patients with hip fracture. The aim of our study is to investigate if more patients with hip fracture experience lasting preoperative analgesia until the time of operation or 20 hours after a femoral nerve block with the addition of Dexamethasone compared to the same nerve block done without Dexamethasone.
The purpose of this study is to evaluate whether an uncemented hip prosthesis is as safe as an cemented hip prosthesis for patients undergoing total hip arthroplasty surgery following a displaced femoral neck fracture.
Due to its prevalence worldwide, osteoporosis is considered a serious public health concern. The worldwide annual incidence of Osteoporotic fractures is approximately 2 million in the US only. Hip fracture is associated with serious disability and excess mortality. Studies have shown that an initial osteoporotic fracture is a major risk factor for a new fracture. An increased risk of 14.8% for a secondary hip fracture has been demonstrated in people that have already sustained a fracture in the past 4 years (In average). These data indicate the major opportunity afforded by secondary fracture prevention strategies. By responding to the first fracture, we can reduce the incidence of second and subsequent fractures. However, even after longer medical follow-up according to regular standard of care, medical treatment and rehabilitation, the medical system has been unable to translate the eminent risk into an effective preventive treatment.
The purpose of this study is evaluate postoperative delirium after general anesthesia and regional anesthesia in elderly patients undergoing hip fracture surgery. Our research hypotheses are: (1) regional anesthesia may contribute to decrease the incidence of postoperative delirium. (2) Regional anesthesia may improve the outcome of elderly patient and reduce healthcare costs associated with postoperative delirium. (3) Postoperative delirium may result in poor long-term functional outcomes.
This small observational study is a contractual component of a 5-year (2013-18) NIHR funded programme called PERFECTED (Peri-operative Enhanced Recovery hip FracturE Care of paTiEnts with Dementia) whose overall aim is to develop and pilot an evidence-based intervention to improve the hospital care of patients with dementia suffering a fractured hip. The findings from this particular observational study will support other PERFECTED work-packages in establishing current care practices in acute hospital settings for older people in general with hip fractures. Observation is a well-established qualitative technique widely used to understand cultures, processes and interactions in defined locations including hospitals. In this study, researchers will observe day-to-day practices on specific ortho-geriatric wards and Emergency Departments in three English hospitals (Norfolk and Norwich University Hospital, Bradford Royal Infirmary and Queen's Medical Centre in Nottingham). Observations will occur intermittently over a 4-week period, covering the full 24h cycle. The prime objective of the study is to describe delivery of care to older patients with a hip fracture including an assessment of cost consequences. Crucially, the observations will focus exclusively upon the hospital personnel that routinely provide care in the designated locations being observed. Other individuals who frequent the locations (patients, visitors and other more peripheral health care professionals) are NOT the focus of the research and will be regarded as "incidental others" rather than "participants". This approach is common in observational research. Observations will be conducted by experienced qualitative researchers and assisted by specifically trained lay researchers to provide a valuable service-user dimension to the study. Field-notes and contextual information will be collected and thematically analysed, again in partnership with trained 'lay' researchers. Resulting data will address the pre-defined aims of the observational study and feed into the findings reported across the whole of work package 1 of PERFECTED.
Up to 35% of hip fracture patients have been shown to experience heart injury after surgery, and as many as 10% have a heart attack or die in the three months after surgery. Hip and knee arthroplasty patients are also at risk of cardiovascular complications. Patients who have these complications have higher levels of inflammation postoperatively. Statins (such as atorvastatin/Lipitor) lower cholesterol and also lessen inflammation. Both of these effects are important in preventing heart attacks. Statins have been shown to reduce the risk of heart attacks in non-surgical patients, and to protect from heart attacks in patients having heart surgery. Whether statins can prevent heart attacks in orthopedic patients is not known. In this pilot study the investigators will treat 30 orthopedic surgery patients (hip fracture, hip or knee arthroplasty) with either atorvastatin or placebo (a capsule with no study drug). Patients will start the study drug prior to surgery and take it for 45 days after surgery. Neither the doctors nor the patients will know whether they are taking atorvastatin or placebo. The investigators will look for evidence of inflammation and heart injury after surgery. The investigators hypothesize that atorvastatin will lessen the degree of postoperative inflammation found in these patients. In this study, the investigators will use a very sensitive test of heart injury that can detect problems even when patients have no symptoms. The investigators hypothesize that this test will demonstrate silent heart injury in over 50% of the hip fracture patients and over 30% of arthroplasty patients in our study. The results of this trial will help us to develop a larger study in 1000 hip fracture and joint replacement patients to determine whether atorvastatin protects orthopedic surgery patients from heart injury and other complications of surgery.
