MDR - Longevity IT Oblique and Offset Liners
Non-inflammatory Degenerative Joint Disease (NIDJD)Avascular Necrosis7 moreThe objective of this retrospective enrollment/prospective follow-up consecutive series PMCF study is to collect data confirming safety, performance, and clinical benefits of the Longevity IT Oblique and Offset liners when used for primary or revision total hip arthroplasty (implants and instrumentation) at a minimum of 10-year follow-up.
SCFE Longitudinal International Prospective Registry
Slipped Capital Femoral EpiphysesSCFESlipped Capital Femoral Epiphysis (SCFE) is the most common disorder of the adolescent hip and diagnosis and treatment of SCFE remain areas of controversy and investigation. The current issues relating to diagnosis stem from an inability to diagnose the condition early on, resulting in increased morbidity. Once diagnosed, there are multiple different options for surgical treatment, including in-situ pinning, and the Modified Dunn procedure. Research is ongoing to determine the parameters that should be considered when selecting a procedure to ensure an ideal outcome. In particular, there is a focus on investigating which treatment method may result in lower incidence of avascular necrosis of the femoral head and femoroacetabular impingement (FAI), two significant long term concerns associated with SCFE. Despite myriad published studies on SCFE, very few are prospective and most lack sufficient patient numbers for clinically meaningful comparative analysis. The aim of this study is to develop a multi-center, international prospective registry of patients with SCFE to facilitate the comprehensive examination of clinical, functional and radiographic outcomes of each treatment, in relation to specific parameters determined prior to intervention. The general registry will serve as a hypothesis-generating database of prospectively collected outcomes. In turn, this will facilitate the development of targeted, hypothesis-testing randomized controlled trials and observational studies that can be housed within the larger registry.

Rheumatoid ArthritisOsteoarthritis6 moreThe purpose of this study is to monitor the performance and determine the metal ion release of the DePuy ASR™ System in the treatment of patients with hip joint disease requiring hip resurfacing surgery. Patients who enter the study will be evaluated at regular intervals following hip surgery using patient, clinical and x-ray assessments. A subset of patients will also have blood samples taken at regular intervals to allow the metal ion levels to be determined and undergo scans to allow the bone mineral density of the bone surrounding the implant to be monitored. DePuy decided to close this Study in 4Q 2009. The Study was terminated with effect from November 2010 to allow for the completion of the 5 year follow up assessments. Please note that subsequent to this decision DePuy voluntarily recalled the ASR products on 24 August 2010.

OsteoarthritisPost-traumatic Arthritis4 moreThe purpose of this study is to monitor the performance and compare the metal ion release of two bearing combinations, ceramic-on-metal and metal-on-metal in the treatment of patients with hip joint disease requiring a total hip replacement. Patients who enter the study will be randomly allocated to one of the bearing combinations and will be evaluated at regular intervals using, patient, clinical and x-ray assessments. Patients will also have blood samples taken at regular intervals to allow the metal ion levels to be determined.

Rheumatoid ArthritisOsteoarthritis6 moreThe purpose of this study is to monitor the performance of a large metal-on-metal bearing from the DePuy ASR™ System in the treatment of patients with hip joint disease requiring hip resurfacing surgery or a total hip replacement. Patients who enter the study will be evaluated at regular intervals following hip surgery using patient, clinical and x-ray assessments. The Study was terminated with effect from 30th November 2011 following the completion of 2 year follow up assessments for those patients remaining in the study. Please note that prior to this decision DePuy voluntarily recalled the ASR products on 24 August 2010.
