Filter by:Patients were recruited at the scheduled preoperative visit for hip or knee arthroplasty. If the haemoglobin (Hb) level was below 13 g/dl with no contraindication to iron supplementation the patients were randomized to the oral or intravenous (IV) group. The oral group received 160 mg ferrous glycine sulfate daily during the month prior surgery, associated with 3 epoetin alpha (EPO) injections (40 000 IU subcutaneous on day - 21, day - 14 and day-7). The IV group received ferric carboxymaltose 1000 mg IV in 15 minutes one month before surgery, associated with 3 EPO injections. Primary efficacy endpoint was the change in Hb level from the day of the preoperative visit to the day before surgery (day-1). Secondary endpoints comprised the Hb level on day 3 and 5 after surgery, allogenic transfusion during and after surgery, and the change in iron indices from the day of the preoperative visit to day - 1.
Leg length discrepancy (LLD) is a complication of THA and may result in patient dissatisfaction, gait disorder, greater trochanter pain, low back pain. In the literature, LLD is reported to vary widely among studies e.g. 6 to 35 mm. However, the threshold at which a LLD is clinically important is still a matter of debate. The aim of this study was to determine the influence of non-corrected LLD after THA on patients' reported hip function and quality of life. This prospective cohort study was conducted at Sundsvall Teaching Hospital in Sweden after it was approved by the regional ethics committee at Umeå University (No. 07-052M and No. 12-287-32M). Between September 2010 and April 2013, all patients with unilateral primary osteoarthritis (OA) treated with THA were considered for inclusion. Informed consent was obtained from all patients. Patients with secondary OA, previous spinal, pelvic, or lower limb injuries or fractures were excluded. The primary outcome measure was the Western Ontario and McMaster Universities Osteoarthritis (WOMAC) Index that measures functional outcome (ref). The secondary outcome measure was the EQ-5D and visual analogue scale (VAS) scale. Patients were assessed preoperatively and at follow-up at 1 year postoperatively. The posterolateral approach was used in all operations. LLD was measured on the postoperative x-rays. patients were divided into three groups: shortening group where the operated leg was more than 5mm shorter compared with the contralateral side, the restoration control group where the operated leg was within 5mm shortening and 9mm lengthening compared with the contralateral side, and the lengthening group where the operated leg became more than 9mm longer compared with the contralateral side.
The purpose of this study is to compare a single preoperative dose of 1g of tranexamic acid (TXA) versus a preoperative dose of 1g of TXA followed by a continuous infusion of 1g over height hours on blood loss.
The purpose of this study is to determine whether an operative hemodynamic optimization using the plethysmographic variability index during orthopedic surgery could decrease the length of hospital stay and the postoperative morbidity.
Hueter anterior approach as described by Siguier allows an anatomical approach without muscle or tendon sections. It minimizes the rate of dislocation after primary total hip arthroplasty (1.5%, Sariali)and seems to allow quicker rehabilitation. The investigators hypothesis was Hueter anterior approach allows quicker functional recovery after partial hip replacement.
This is a pilot study to provide preliminary data of the association between bone mineral denity adjacent to acetabular implants, as measured by quanitative computed tomography (QCT), at least 2 years post Total Hip Arthoplasty (THA) surgery with Mesechymal stem cell assays, obtained at time of surgery, and to begin to evaluate if stem cells can predict orthopaedic surgical outcomes.
The couple of friction metal-polyethylene is regarded as the couple of reference in spite of the osteolysis induced by the wear of the polyethylene which remains the independent factor of long-term failure. This is all the more true as the patients are young, thus justifying the recourse to alternate couples of friction. The Metasul® couple was introduced on the French market under its current form in 1995 (year of its marking EC). The use of a couple of friction metal-metal (MM) is justified because it would be likely to improve longevity of the total arthroplasties of the active subjects by the reduction in osteolysis related to the wear of polyethylene. Various studies highlight evolutions different according to the types of fixing acetabular; favourable results of the not cemented cups contrasting with unsealings and the evolutionary edgings of the Metasul® cups cemented of or the cups "of cemented Weber type".
In this study, the investigators utilized the 18F-fluoride PET method to evaluate THA cases with a stable, septic or septic loosened implant in order to differentiate these clinical settings using a novel uptake type classification approach.
The purpose of this research study is to determine if the insertion site of a perineural catheter, or tiny tube placed next to the nerves that go to the hip which you will have surgery, affects the amount of pain relief that is experienced after surgery.
Postoperative administration of local anesthetics is effective for postoperative pain management across surgical specialties but the optimal type of catheter (single, few or multiholed catheters) has not been determined. This study investigates wound spread of a radioactive isotope (technetium) administered in different types of catheters after total hip arthroplasty.
