Filter by: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 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.
Hip implants come in different sizes. Currently, surgeons predict the implant size that will be needed using an analogue method whereby photos of the implant sizes are overlaid on the x-rays. In this study, we propose to use a digital, computerized method of templating which we expect will be more accurate than the overlay method.
