Filter by:The purpose of this study is to determine whether anterior cruciate ligament injury in patients wishing to return to sports activities may be treated with repair supplemented with internal brace compared with a standard operation using a patella tendon autograft.
The study is to evaluate the accuracy of a test device called "PAMG-1" to see if a pregnant women has ruptured membranes in comparison to standardly used testing methods.
The investigators will evaluate the benefit of a new bioresorbable screw for repair of anterior cruciate ligament over 3 years.
The proposed study will establish novel relationships between intra-articular mesenchymal stem cell (MSC) recruitment, synovial inflammation, biomarkers of cartilage degeneration and joint inflammation, clinical patient factors, and downstream alterations in cartilage composition and morphology to provide novel insights into the pathoetiology of post-traumatic osteoarthritis (PTOA) after ACL injury and reconstruction. The study aims to enroll N=38 total patients with primary, isolated rupture to their anterior cruciate ligament (ACL), who have agreed to participate in the study and who will undergo primary surgical reconstruction by an orthopaedic physician at our two sites. Patients will undergo baseline magnetic resonance imaging (MRI), baseline clinical evaluation, and undergo a baseline blood draw. Subsequent imaging and clinical evaluations will be longitudinally performed at several postoperative timepoints up to 12 months postoperatively.
Eligible subjects in this study will have either a known abdominal aortic aneurysm (AAA) or because they do not have an AAA (control group). The purpose of this research study is to further study, through FEA, changes that occur in the mechanical properties of the aortic wall. The investigator will compare two radiotracers, 18F-FDG and 11C-PBR28 to determine if one provides more useful and reliable information about inflammation. 18F-FDG and 11C-PBR28 are radioactive drugs that will be used for imaging during the PET-CT scan. The investigator will also compare the results describing the mechanical properties of the AAA wall to the degree of inflammation in that wall as determined by PET-CT imaging to define new and better predictors of AAA growth and/or rupture.
Aim 1: The primary aim of this study is to test the feasibility of Mechanical Diagnosis and Treatment (MDT) +/- transforaminal epidural steroid injections (TESI) on pain and disability in patients awaiting physiatry consult for lumbar radiculopathy secondary to lumbar disc herniation, compared to usual care within the current healthcare system in Calgary, Alberta, Canada. Hypothesis: the investigators hypothesise that centralisers treated with MDT and non-centralisers receiving TESIs + MDT will have demonstrate reductions in self-reported pain and disability, compared to usual care controls. Aim 2: the investigators will also describe the potential impact on healthcare resources by tracking surgical rates and self-reported healthcare utilisation during the study period. Hypothesis: based on predicted reductions in pain and disability, the investigators hypothesise that there will be a trend toward overall less healthcare utilisation (including surgery) in the MDT guided group compared to the surgical wait list group.
Aneurysms of the thoracic ascending aorta are a serious pathology which may threatens life by rupture or dissection. Their incidence is estimated at 10.4 per 100,000 people. At present, the only parameter for assessing the risk of complication is the maximum diameter of the aneurysm. The only way to avoid a complication is a surgical replacement of the aneurysmal aorta by a prosthetic tube. This procedure is performed by sternotomy and with extracorporeal circulation and its death rate ranges between 3% and 5%. Surgical repair is indicated when the diameter of the aneurysm exceeds 5.5 cm for degenerative atheromatous aneurysms or 5 cm in a patient with genetic disorder of connective tissue (Marfan disease or Ehlers-Danlos syndrome). However, there are aneurysms with diameter greater than the surgical threshold which remain stable. Conversely, complications have been described for aneurysms less than 4.5 cm in diameter. The criterion of diameter appears therefore as inadequate to assess the risk of complication of an aneurysm of the ascending aorta.Multiple methods have been described in the literature. One of them relies on in vitro mechanical testing on healthy or aneurysmal tissue. Another method is the vivo analysis from imaging (CT, MRI or ultrasound). So far, no algorithm is robust enough for predicting the risk of complication better than the universally used criterion of diameter. The pathophysiology of these aneurysms has also been explored from histological studies. The investigators know that the microstructure of the aortic wall of an aneurysm is deteriorated with a degradation of elastin fibers and collagen that determine to a large extent its biomechanical behavior. Histological analysis appears inseparable from biomechanical analysis.
Bed rest has been a commonly prescribed intervention for high risk pregnancies, despite the lack of data to support its benefits, and increasing evidence pointing to potential harms. In this study, the effects of bed rest compared to moderate activity will be on maternal mood and muscle strength will be evaluated in patients with preterm premature rupture of membranes (PPROM).
The purpose of the study is to compare the treatment by wearing shoes inclined at kinesitherapy because it is the first treatment offered by primary care physicians in chronic Achilles tendinopathy.
The purpose of this study is to compare safety and efficacy outcomes of the L-C Ligament versus Hamstring Autograft for treatment of acute rupture of the ACL.
