Filter by:The total hip replacement, with over 120,000 cases per year in France, provides short term, excellent functional results and a significant improvement in quality of life, in almost all cases. However, observation showed that the dislocation is not a rare complication (2-4%) and the lifetime of the implants is limited due to aseptic loosening. The evaluation process used in this study will be the extent of penetration of the metal femoral head in the cup and micro mobility metal back by radiostereometric analysis (RSA) whose precision provides early results (2 3 years), long before wear and migration are measurable by conventional radiological means. The main objective will be to compare, 2 years after the intervention, the penetration of the metal femoral head in 3 types of inserts: two dual mobility inserts, one at tripod attachment (Novae E®), the other press fit pure (Sunfit®), and a fixed insert (Quartz®). This is a randomized controlled trial. 105 patients will be enrolled (35 in each group). Patients will be included in each of the two participating centers (Amiens, Caen). The analysis will be made in RSA D7 + 2, 6 months 1, 12 months 1 24 months 1. An assessment will be made to 3 years if the analysis requires it to 2 years. Analysis of pictures will be centralized in Caen and performed with specific software after transferring images via a secure network.
The total hip replacement, with over 120,000 cases per year in France, provides short term, excellent functional results and a significant improvement in quality of life, in almost all cases. However, the observation has shown that the lifetime of the implants is limited due to aseptic loosening. One of the factors associated with these failures is a peri-prosthetic osteolysis wherein the polyethylene wear debris (PE) have been implicated. Several solutions have been proposed: change the friction torque (hard-hard pairs using ceramic or metal on the two components of the couple) or improving quality polyethylene. Improving the resistance of polyethylene wear is the primary objective evaluated in this study.
This study is designed to compare the effect of IPC on post-operative circulation in lower limbs with gekoTM device after total hip replacement procedure.
Infection is a serious complications after undergoing total hip replacement. It occurs in about 1% of cases. The optimal treatment of these infections is discussed. The team validated by international publications change strategy of the infected prosthesis at a time. Antibiotic prophylaxis has significantly reduced the infection intraoperative contamination in orthopedic surgery rates. It must be conventionally administered before the surgical incision. In response to infection, it is typically recommended to start this antibiotic after the completion of the deep bacteriological samples, so as not to negate the risk of these samples by the prior administration of antibiotics. This attitude, however, is not formally validated by the scientific literature. In contrast, two recent publications challenge this practice, and suggest the use of a conventional antibiotic prophylaxis even in septic interventions. Our multidisciplinary team opted for a few months for this new strategy. We wish to evaluate the influence of this new approach results in the treatment of infection in total hip or knee.
The investigators propose to deploy an interactive device to monitor the patient's recovery and vital signs at home after joint replacements. These will be early discharge patients on the same day or the next morning. The goal will be to support early discharges by creating a safe, controlled, and monitored environment at home.
Does having a large diameter metal on polyethylene total hip replacement increase metal ion release. Larger metal heads are thought to have increased torsional forces on the trunion which would like release more metal ions. Increased metal ion levels have been associated with adverse local tissue reactions. Are there any differences comparing these groups to a dual mobility type total hip replacement.
The purpose of this observational study is to evaluate the baroreceptor function in relation to surgical inflammation and orthostatic intolerance after elective hip arthroplasty. The main hypothesis is that baroreceptor function is attenuated after surgery and related to surgical inflammation.
Total Hip Arthroplasty (THA) is one of the most commonly performed orthopaedic operations worldwide. The main aim is overall improvement in levels of patient pain and mobility. Such surgery involves implantation of both an acetabular and femoral component. With the patient in the lateral decubitus position, the Orthopaedic Surgeon assumes that the pelvis is in a neutral position with respect to all three body planes at the time of acetabular component implantation. With regard to THA, the current orthopaedic literature demonstrates a clear relationship between acetabular component positioning, polyethylene wear and risk of dislocation. Problems with edge loading, stripe wear and squeaking are also associated with higher acetabular inclination angles, particularly in hard-on-hard bearing implants. The important parameters of acetabular component positioning are depth, height, version and inclination. Control of acetabular component inclination, particularly in the lateral decubitus position, is difficult and remains a challenge for the Orthopaedic Surgeon. Accurate implantation of the acetabular component within the 'safe zone' of radiological inclination is dependent on: - Operative version - Operative inclination - Pelvic position (Primarily, but not exclusively, abduction / adduction.) This study aims to investigate the effect of patient pelvic positioning and method of acetabular component insertion on acetabular component inclination during Total Hip Arthroplasty (THA).
Studies have shown that surgery causes some reactions in your body consistent with inflammation. When the inflammation is extensive, it may affect different parts of the body including the lungs. Corticosteroids are commonly used to treat inflammation and are different from performance enhancing steroids associated with athletics. The purpose of this study is to determine the influence of low dose steroids given 3 times in a 24 hour period on thrombotic markers (markers that are associated with increased risks of clotting, a possible complication of surgery), IL-6 cytokine release (part of the stress response seen with surgery), and urine desmosine levels (a marker of lung injury) in a randomized placebo controlled trial patients undergoing total hip replacement.
The investigators want to contact patients that underwent total hip replacement for the past ten years. The investigators will ask them about their daily living, functioning and quality of life.
