Filter by:Two-year (2 year) information regarding the performance of the commercially available Actis™ Total Hip System in order to obtain and evaluate the clinical outcomes on a series of cementless primary total hip arthroplasty (THA) and hemi-hip arthroplasty procedures using clinical, radiographic and device and procedure related adverse event assessments.
This is a Post-Marketing Surveillance of SMS femoral stem prosthesis.
Although older children and high dislocations may be more likely to require a femoral shortening osteotomy, the ultimate decision about whether or not to shorten a given femur should depend on the ease of femoral head reduction in that specific patient. Adding a femoral shortening procedure increases operating time and blood loss, adds a second incision, and necessitates future hardware removal. In addition, an unnecessary femoral shortening osteotomy could overly decrease the soft tissue tension around the joint, putting the hip at risk for redislocation. This study was designed to explore an algorithm based on strict age and radiographic criteria that identify those without the need of femoral osteotomy.
The aim of this study is to assess long term effects of developmental dysplasia of the hip (DDH) to overall health and quality of life later in life. We compare hip radiographs, hip symptoms, clinical examination, head asymmetry, dental examination and intraoral scans of 170 children and young adults treated for DDH in their childhood with age and sex matched controls.
A clinical trial of total Hip system used in Primary Total Hip Arthroplasty in China.
Patients undergoing a hip scope procedure will be recruited for this study. They will be randomized to either receive a nerve block or no nerve block (pain medicine only). Pain levels and clinical outcomes will be assessed through 3 months post-operatively.
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.
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.
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.
