Filter by:This study aims to collect normative population data on the ultrasound radiographic parameters used to evaluate hip dysplasia in infants between 32 and 46 weeks of gestational age. This data would be utilized to develop a growth chart with standard deviations for this cohort that would be beneficial in the appropriate treatment of suspected hip dysplasia.
Although evidence is amassing regarding the role of intra-articular pathology in the surgical management of adolescents and adults with hip dysplasia, the optimal method of detection and especially management of this pathology remains unclear. No studies exist to compare clinical outcomes and hip survival between arthroscopy and arthrotomy in patients with mechanical hip pain undergoing periacetabular osteotomy (PAO) for dysplasia, and this is what the investigators aim to achieve in the current prospective randomized surgical trial.
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.
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.
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.
The aim of the randomized controlled trial was to determine whether the addition of a general or of a selective ultrasound screening program resulted in more appropriate criteria for treatment and a reduced prevalence of late DDH compared with clinical examination alone.
Follow up study of patients, who despite periacetabular osteotomy, need a total hip arthroplasty, to see outcome.
The main objective of this study is to predict cartilage contact pressures in the hip after periacetabular osteotomy (PAO).
