Filter by:This is a prospective, randomized, multicenter clinical study in Chinese subjects to compare the safety and efficacy of the Delta PLUS Femoral Head and SL-TWIN Stem with BIOLOX forte ball head and SL-PLUS Stem in total hip arthroplasty
Introduction: The lack of congruence between the acetabulum and femoral head in hip dysplasia compromise the passive stability of the hip joint resulting in increased stress on the acetabular labrum, joint capsule and the muscles acting close to the hip joint. Soft tissue injury is present in hip dysplasia, and pathology of the iliopsoas muscle has been found in 18-50%. To our knowledge, no studies have systematically examined the prevalence of soft tissue pathology in hip dysplasia. The overall aim of this research project is to examine soft tissue pathology in 100 patients with hip dysplasia prior to and one year after Periacetabular osteotomy (PAO). Methods: Soft tissue pathology will be examined in a prospective cohort study on 100 patients with hip dysplasia prior to and one year after surgery. Pathology will be examined using ultrasonography and the Clinical Entities Approach that focus on pathology of the iliopsoas, adductors, rectus abdominis, gluteus medius and hamstrings. Furthermore, hip muscle strength is tested with a dynamometer, hip related health is measured with the Copenhagen Hip and Groin Outcome Score (HAGOS) and physical activity is measured with triaxial accelerometers during a period of 7 days. Perspective: Is it possible to demonstrate pathology of the hip muscles and tendons applying clinical tests, muscle strength tests, and ultrasonography, as it has been found in sports-active people with groin pain, it will make sense to plan and test a specific training program focusing on the pathological soft tissue pathology.
This randomized controlled trial will compare proximal femoral resection-interposition arthroplasty to proximal femoral resection with subtrochanteric valgus osteotomy for the treatment of painful irreducible hip dislocation in patients with cerebral palsy. The primary outcome is quality of life and care giver burden measured by The Caregiver Priorities and Child Health Index of Life with Disabilities (CPCHILD) score at one year. Secondary outcomes will include pain (NCCPC-R, PROMIS pain intensity and PROMIS pain interference), function (mobility questions), complications and surgical parameters such as OR time and fluoroscopy time. A cost-effectiveness analysis will follow completion of the randomized controlled trial (RCT). The authors hypothesize that mean CPCHILD scores (measured at 1 year) will be significantly higher following the Subtrochanteric Valgus Osteotomy technique compared to Proximal Femoral Resection-Interposition Arthroplasty technique. Furthermore, the Proximal Femoral Resection-Interposition Arthroplasty technique will have a shorter length of hospital stay, shorter fluoroscopy and OR times and the Subtrochanteric Valgus Osteotomy will have longer sitting tolerance, less pain, smaller burden for caregivers, better health, and higher quality of life. Additionally the authors hypothesize that Subtrochanteric Valgus Osteotomy will be more expensive than Proximal Femoral Resection-Interposition Arthroplasty, due to the cost of the plate, longer operative time, longer length of stay, and blood loss, but Subtrochanteric Valgus Osteotomy will be preferred by patients due to less pain and better functional and quality of life outcomes.The results of this study are expected to improve outcomes for children with cerebral palsy with painful irreducible dislocated hips.
The goal of this randomized controlled, double-blinded trial is to assess the efficacy of intravenous tranexamic acid, a drug, in reducing blood loss and transfusion in patients undergoing periacetabular osteotomy, an elective reorientation procedure for the hip joint. The investigators hypothesize that tranexamic acid will be more effective than placebo (normal saline solution) in reducing blood loss and transfusion after periacetabular osteotomy.
This is a multi-centre, prospective post marketing surveillance study to assess mid-term performance of the Mpact cup in subjects requiring primary total hip arthroplasty.
One of the leading causes of hip arthritis is developmental dysplasia of the hip (DDH). DDH can lead to major damage in the hip joint and may result in hip arthritis later in life. Patients recruited into this study will be undergoing corrective hip surgery within the next 6 months with a goal of preventing further hip problems down the road. This study is being done to see how well a newer type of Magnetic Resonance Imaging (MRI) detects hip cartilage damage compared to an older but well validated MRI method.
Developmental dislocation of the hip is a common disease in children, and its incidence in China is about 9 ‰.The pathological changes of it is complex. The reluxation , subluxation and residual deformity and other complications are relatively common after treatment. The X-ray appears great acetabular index and wide medial gap , small central-edge angle. As there is no effective methods for treating such complications , investigators conducted this trial to find and prove optimal intervention time and treatment programs.
The study will evaluate the radiographs (x-rays) of 100 patients with a TriFIT total hip at 2 weeks, 3 months, 6 months, 12 months, and yearly following surgery to see if there has been any movement or wear in the hip stem over the course of the study. The study will also record clinical data on each patient using various functional tests and questionnaires at the same intervals.
Pathogenesis of hip dysplasia Hip dysplasia is multifactorial in origin influenced by genetic and intrauterine factors, such as mechanical (rump presentation and oligohydramnios) and hormonal factors1. To ease the passage through the birth canal, the hip joint is quite mobile perinatally. Postnatally, the laxity of the ligaments will subside and the femoral head will normally position itself deeply in the acetabulum2. The theory is that if the femoral head does not migrate sufficiently into the acetabulum, dysplasia may develop because the matrice to stimulate acetabular growth is not correctly positioned. Normally, at birth the femoral head sits deep in the acetabulum held by surface tension of the synovial liquid. The growth and the hemispherical morphology of acetabulum are dependent on the presence of a normally growing and correctly placed spherical femoral head that works as a convex matrice. If for some reason the normal development is disturbed pre- or postnatally, pathologic relations may develop between the femoral head and the acetabulum3, leading to hip dysplasia. Purpose of this research project is to investigate if the correction of the acetabulum is accurately performed when the surgeon use navigation equipment during PAO.
Early treatment is considered essential for developmental dysplasia of the hip (DDH), but the choice of screening strategy is debated. The investigators evaluated the effect of a selective ultrasound (US) screening programme. All infants born in a defined region during 1991-2006 with increased risk of DDH, i.e. clinical hip instability, breech presentation, congenital foot deformities or a family history of DDH, were subjected to US screening at age one to three days. Severe sonographic dysplasia and/or dislocatable/dislocated hips were treated with abduction splints. Mild dysplasia and/or pathological instability, i.e. not dislocatable/dislocated hips were followed clinically and sonographically until spontaneous resolution, or until treatment became necessary. The minimum observation period was 5,5 years.
