Active clinical trials for "Hip Dislocation"

This is a Post-Marketing Surveillance of SMS femoral stem prosthesis.

Explore the influence of hip replacement on lower extremity hemodynamics in Crowe Ⅳ hip dysplasia patient.

Developmental dysplasia of the hip (DDH) is the most common childhood hip condition. When caught early, bracing is the most frequently used treatment; however, the brace can disrupt important mother-baby bonding time in the newborn period and present challenges to daily living. In babies with mild DDH, some studies have suggested that their hips may improve naturally as they grow and develop. This study will look at whether careful monitoring can be just as good as bracing for babies diagnosed with mild DDH less than 3 months of age, potentially avoiding unnecessary treatment. This will be the first study to look at this question with babies being treated at different hospitals in seven different countries, so the results will make an impact on children and families worldwide.

The orientation of the femoral neck in relation to the coronal or transcondylar axis of the distal femur is known as the femoral version. It is categorised as femoral anteversion when the femoral neck axis is anteriorly rotated in relation to transcondylar axis, while femoral head axis is anterior in relation to the femur coronal plane; or femoral retroversion when the femoral head-neck axis points are posterior to the femoral coronal plane. Some studies suggest that conventional radiography cannot adequately measure femoral version, and should be avoided in favour of more precise methods using computed tomography (CT) scanning. CT imaging is currently the reference method for measuring femoral version. However, its clinical use is limited by issues such as high levels of radiation exposure, which can adversely affect patients, especially children. Magnetic resonance imaging (MRI) is considered an alternative for measuring femoral version; however, it is expensive, time consuming and subject to motion artifacts. The associated costs and risks of MRI increase when anaesthesia is needed for the examination. The EOS imaging system could provide an alternative to the previously mentioned techniques. It uses lower doses of irradiation and the sterEOS software allows the production of 3D images. This study aims to compare the accuracy of the EOS imaging system with CT for the measurement of hip parameters in individuals aged 13 years and older. In addition, this study aims to correlate EOS and CT parameters with gait analysis and compare the ability of EOS and CT to predict gait abnormalities.

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.

Psychosocial conditions are common in young adults with hip pain including depression, anxiety, pain catastrophizing, and narcotic use. The incidence of these conditions is not well defined. Interventions to optimize psychosocial conditions with non-surgical or surgical treatments has not been investigated. The goal of this project is to determine the incidence of psychosocial conditions in the young adult population with hip pain and determine if cognitive based therapy can improve clinical outcomes in these individuals.

This is a prospective, non-randomized, consecutive series, multicentre, observational study to evaluate the clinical outcome of ceramic-on- ceramic hip resurfacing arthroplasty using the ceramic, non-porous, non-cemented H1 Hip Resurfacing Arthroplasty. It includes a safety study followed by an efficacy study. Patients will be followed up for 10-years postoperatively. The primary aim is to confirm the safety of the H1 hip resurfacing prosthesis by demonstrating non-inferiority of the H1 device in terms of survivorship. The secondary is to evaluate superiority of the ceramic-on-ceramic H1 hip resurfacing prosthesis compared to Metal-on-Metal (MoM) hip resurfacing in terms of absence of metal ion release.The primary end point is revision for any reason.

This study is a multicenter, prospective, non-controlled post market clinical follow-up study. The objectives of this study are to confirm the safety and performance of the commercially available Zimmer® Maxera™ Acetabular System in Total Hip Arthroplasty.
