Sequelae of Developmental Dysplasia of the Hip
Developmental Dysplasia of the HipHip DysplasiaThe 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 Randomised Study to Compare Metal Ion Release and Long-term Performance of the Pinnacle™ Cup With...
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.

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 December 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. Additional information regarding this voluntary recall and the follow-up of patients affected by the recall can be found at the following links http://www.mhra.gov.uk/Publications/Safetywarnings/MedicalDeviceAlerts/CON079157 and http://www.depuy.com/countries_list.

OsteoarthritisPost-traumatic Arthritis6 moreThe purpose of this study is to compare the performance of 4 designs of the DePuy Ultima LX hip stem 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 4 designs of the DePuy Ultima LX hip stem and will be evaluated at regular intervals following hip surgery using patient, clinical and x-ray assessments.
Metal on Metal Versus Metal on Highly Crossed Linked Polyethylene Sytem
OsteoarthritisAvascular Necrosis5 moreThis trial will evaluate the 36mm or greater metal head on metal hip system and compare it to the 32mm or 28mm metal head on polyethylene (liner) hip system in patients receiving a primary cementless total hip replacement.
