Filter by:Aim of the study is to specify the best analgosedation technique during placement of regional anaesthesia from the patients' view. In this double blind randomized trial the investigators will be testing the application of drugs administered intravenously (fentanyl-bolus, remifentanil-infusion, clonidine-bolus) or transcutaneously (EMLA salve) or placebo (NaCl 0,9% i.v. and skin protection salve).
Background - In the 19th century, Sir John Charnley successfully introduced total joint replacements for hips. In order to prevent implant fixation failure and accelerated polyethylene wear, it was initially recommended that implants were systematically positioned in a "biomechanically-friendly" way, which disregarded most of the individual anatomy (medialized acetabular cup, systematized cup version and inclination, etc.) - While those initial surgical techniques made popular and clinically successful total joint replacements, many complications (aseptic loosening, pain, excessive wear) have remained and mainly the persistence of frequent instability after THA. In response to those complications, many improvements were developed in the area of joint replacement over the last few decades, with one the most recent dating from 2017 and being the development of a surgical technique Rationale - The kinematic alignment (KA) technique for total hip arthroplasty (THA) aims at restoring the acetabular center of rotation and as much as possible the constitutional acetabular anteversion by using the transverse acetabular ligament (TAL) as a reference landmark. Also, the technique aims (1) at making personalized choice for the hip component design, (2) at defining the cup positioning, and (3) at sometimes considering additional spine surgery based on the assessment of the individual spine-hip relation. - KA techniques for hip replacements are relatively new, likely to become popular over time, and their true value remains to be determined.
The aim of the study is to assess the ideal bearing surfaces in hip replacement by comparing 4 different combinations. In a hip replacement this means what the head and the socket liner are made of.
This is a post-market, retrospective with one prospective visit, multi- center study, designed to assess the clinical outcomes, surgical details including Anterior or Posterior surgical approach, and collect all complication data of Medacta Versafit Cup DM used for primary or revision total hip arthroplasty at minimum two year post- operatively.
The aim of the recovery protocol is to reduce surgical trauma, postoperative pain, and complications, shorten hospital treatment and improve postoperative recovery. Orthopedic and traumatology surgeries are often followed by a long-lasting recovery with difficulties of everyday functioning. Up to this time, only a few publications of multidisciplinary protocol in orthopedics and traumatology have been published, mostly to improve the care of patients after elective surgical procedures. The goal of multidisciplinary after surgery recovery program in orthopedics and traumatology is to improve the care of both urgent and elective patients using standardized, multi-professional care programs. It focuses on patient education, preoperative respiratory training, adequate nutritive and hemodynamic support, modified anesthesia protocol, prevention of postoperative pain, nausea and vomiting, and early postoperative delirium detection. The implementation of the program will reduce the rate of postoperative complications and the rate of rehospitalization, enhance the recovery after surgery and increase the satisfaction with the treatment.
Patients with primary hip osteoarthritis (OA group) and patients with inflammatory hip disease (RA group) and healthy subjects (control group) are enrolled in the study. The aim of our study is to determine the postural control in patients suffering from OA and RA of the hip joint during different conditions, i.e., on both stable and compliant surfaces with opened or closed eyes to determine the possible differences between these two diseases in this respect.
The care for patients receiving total hip and knee arthroplasty at the University of Arkansas for Medical Sciences has followed a structured care pathway since July 2015. This system of perioperative care has focused on preoperative assessment of medical co-morbidities and risks to postoperative functional recovery, anesthetic care focused on postoperative nausea and vomiting prevention and optimizing immediate postoperative functional ability, and aggressive postoperative physical therapy. This is an observational study to look at the outcomes of this program at University of Arkansas for Medical Sciences. Areas of focus will be hospital length of stay, postoperative narcotic consumption, Visual Analog Scale scores, incidence of postoperative nausea and vomiting, and 30-day readmission rates, and health literacy rates.
To investigate the association between grip strength and preoperative pain threshold as measured by pressure algometer and validated pain outcome surveys.
Clinical and radiological 10 year results of Excia T® Hip Stem
The purpose of this study is to determine the relative effectiveness of two drug agents, Tranexamic acid (TXA) and aminocaproic acid (Amicar), that act through a similar mechanism of action. These agents are used to decrease blood loss that is a result of major surgery, like total joint arthroplasty. A secondary goal will be investigate the cost-analysis of total hospitalization. Both TXA and Amicar are both currently used in the care of patients undergoing total joint arthroplasty. Subjects will be randomly assigned to the TXA or Amicar arm. All data needed for this study including blood loss, need for transfusion, preoperative and lowest postoperative hematocrit and hemoglobin, and complications will be collected during the hospitalization stay. Our Hypothesis is that TXA and Amicar will have similar effectiveness in preventing intraoperative blood loss and the need for transfusion post-op than Amicar. A detailed cost analysis will show that the overall cost of performing the operative procedure, including transfusions, OR time, and total costs associated with admission cost will be more decreased with Amicar as compared to TXA.
