View clinical trials related to Total Hip Arthroplasty.
Filter by:Spinal anesthesia is commonly used in patients undergoing total hip replacements. The purpose of this study is to compare lidocaine to bupivacaine spinal anesthesia in patients having a total hip arthroplasty (THA). The objective of this study is to compare the two spinal anesthesia treatments in regards to transient neurological symptoms (TNS).
This study will evaluate if the addition of dexamethasone to a local infiltration analgesia mixture will improve functional outcomes following total hip and knee arthroplasty.
Total hip arthroplasty (THA) is one of the most effective medical procedures. Except for the few early complications (acute infections and dislocations), the patient made a PTH can be assured of a significant improvement in its function and its short-term quality of life. However, clinical studies and records have shown that the lifetime of these implants was limited. The main cause of failure is the "aseptic loosening" influenced by many factors, foremost of which is due to periprosthetic osteolysis debris. This is a major concern for orthopedic surgeons loosening leads, in most cases, the recovery, the importance of osteolysis is a major cause of difficulties and poorer results. The main objective of the study is to compare, 2 years after the intervention, the penetration of the femoral head in the polyethylene and X3 in the acetabulum in N2VAC® conventional polyethylene.
Post-marketing clinical study,international, multi-centre, prospective, observational. The investigation will be carried out in 2 sites in Europe for a maximum total number of 160 patients.The aim of this study is to assess clinical, radiographic and subjective outcomes after hip arthroplasty with a cementless metaphyseal MINIMA short stem, define the survivorship of the implant and identify possible risk factors that may lead to failure.
We are comparing two pneumatic compression devices, VenaFlow (stationary) and MCS (portable) in both the supine an standing position. We will start supine and will take 3 baseline measurements of venous velocity and then apply a device and take 3 measurements of the increase in peak venous velocity. We will repeat this with the second device. We will then have the subject stand and repeat the above with each device. We will randomize the order of the devices in the supine and standing position. This study will involve 10 healthy subjects of various ages and 10 total hip replacements (THR) patients.
Several studies exist on patient performance in drive simulators especially around and after surgery. Recommendations concerning the ability to drive preoperatively are based on these studies, which generated their data using drive simulators. However, in all the datasets driving performance remains highly individual. Since a drive simulator is not readily available in normal general practitioner surgeries it would be helpful to have convenient clinical tests to evaluate a patients individual ability to perform an emergency stop. This study aims at evaluating different possibilities how such performance might be predicted. Patients with hip osteoarthritis and patients who have received total hip arthroplasty are tested clinically and their results are compared with the gold standard experiment - a drive simulator.
In vitro, Vitamin-E diffused, highly cross-linked polyethylene (PE) have been shown to have superior wear resistance and improved mechanical properties as compared to that of standard highly cross-linked PE. There are as of yet no published studies with vitamin-E diffused PE although several trials are ongoing. All of these trials use uncemented acetabular cups intended for biological fixation. In many countries the standard fixation method for the acetabular component is bone-cement. The Vitamin-E used in implants is alfa-tocopherol, a lipid-soluble antioxidant with oily consistency; theoretically affecting cemented fixation when used in acetabular components. The aim of the study is to compare migration, linear wear and clinical results between two types of cemented acetabular cups.
Total hip arthroplasty is a one of the most commonly performed surgical procedures with increasing numbers anticipated over the next several decades. The purpose of this study was to find a better way to make patients comfortable after their hip surgery. Three different ways of providing pain relief were compared, a peripheral nerve block in the lower back outside of the spinal space (using bupivacaine, a numbing medicine), or injections around the hip joint with one of two different medicines, either Ropivacaine or Liposomal Bupivacaine (Exparel®).
The purpose of this research study is to evaluate the analgesic efficacy of adding a single shot parasacral (sciatic) nerve block to a continuous lumbar plexus block in patients undergoing total hip replacement.
This study had four aims: 1. To evaluate the correlation between the planned preoperative cup size and the actual cup size that was implanted in surgery. 2. To examine the absolute difference between the implanted cup size diameter and the actual femoral head size diameter. 3. To examine the absolute difference between the planned cup size diameter and the actual femoral head size diameter 4. To suggest an additional online monitoring tool on the accuracy of the preoperative process and implant selection. We hypothesized that high accuracy rates will be found between the preoperative planned cup size and the actual implanted cup size. Furthermore, we hypothesized that strong correlations will be found between the planned and actual implanted cup size and the actual femoral head diameter size.
