NCT ID: NCT01305759 Completed - Depression Clinical Trials

Psychological, Sexually and Social Consequences of Osteoarthritis Treatment With THA or TKA and Joint Preserving Surgery

Start date: April 2010
Phase: N/A
Study type: Observational

The project runs as a Ph.d. project at the Faculty of Health Sciences- University of Copenhagen. In Denmark the investigators operate around 16.000 artificial hips and knees yearly, mainly due to osteoarthritis. The numbers has increased with 13,9% for hips and 50,7% for knees in the period 2004 to 2007. In 10% of the cases, or approximately 1.600 patients, the patient is younger than 50 years - mid-life, working, socially active and sexually active. The investigators have a tendency within in the orthopedic society to mainly focus on the technological aspects of the procedure and tend to forget that this is a key event for the patient with widespread consequences for the patient and his future life. Hip- and knee arthroplasties is without no doubt two of the most important and successfully surgical procedures ever introduced. The economical cost for osteoarthritis treatment has exploded in the developed world over the last decade, with a yearly growth on 8%. Because of the limited lifetime for an artificial hip or knee, this treatment can be unfortunate for the young patient. This has over the last years led to an increased interest for joint preserving surgery. Over the last twenty years it has been tried to delay the time for total hip arthroplasties for patients with hip dysplasia with the aid of Ganz osteotomy. Since this technique was introduced back in 1988, the research on the topic has had its main focus on optimizing the operation technique. So as with surgery with artificial hip or knee the investigators have a lack of knowledge regarding the social, work related, psychological and sexual aspects of this treatment. Purpose The consequences of an artificial hip or knee joint regarding patients' social-life, work, psychological and sexual aspects gain very little attention international. The investigators apply most of our research funds exclusively to research and development of the surgical track and procedure, new prosthesis designs or coatings. The investigators find this study highly relevant because this kind of studies has been preformed for several chronic diseases but not osteoarthritis and its treatment. With this study the investigators wish to examine the social, work related, psychological and sexual aspects of end stage osteoarthritis. This will lead the way for improved information to the patient and improve the surgeons' possibilities for chosen the correct time for surgery.

NCT ID: NCT01285843 Completed - Osteoarthritis Clinical Trials

Periprosthetic Bone Mineral Density After Total Hip Arthroplasty Performed Through a Minimally Invasive Anterior Approach (AMIS) With Either an AMIStem or a Quadra Femoral Component

Start date: September 2010
Phase: N/A
Study type: Interventional

This is a monocentric, prospective, randomized clinical survey to verify if the periprosthetic remodelling brought about either the AMIStem or the Quadra femoral component is equivalent.

NCT ID: NCT01193673 Completed - Hip Dysplasia Clinical Trials

Discovering the Gene(s) Causing Developmental Dysplasia of the Hip (DDH)

Start date: January 2010
Phase:
Study type: Observational

The primary objective of the study is to find the gene(s) responsible for causing DDH. The secondary objective of the study is to determine the mode of genetic transmission of DDH.

NCT ID: NCT00872066 Completed - Clinical trials for Rheumatoid Arthritis

A Study to Assess the Long-term Performance of SmartSet® HV and SmartSet® GHV Bone Cements in Primary Total Hip Replacement

Start date: March 2006
Phase: Phase 4
Study type: Interventional

The purpose of this study is to monitor the performance of artificial hip joints implanted with two different bone cements, SmartSet® HV and SmartSet® GHV, in the treatment of patients with hip joint disease requiring a total hip replacement. Patients who enter the study will be randomly allocated to SmartSet® HV or SmartSet® GHV and will be evaluated at regular intervals following hip surgery using patient, clinical and x-ray assessments

NCT ID: NCT00843258 Completed - Clinical trials for Developmental Dysplasia of the Hip

Treatment for Mild Hip Dysplasia in Newborns

Start date: February 1998
Phase: N/A
Study type: Interventional

Developmental dysplasia of the hip is the most common musculoskeletal disorder in infancy, with a reported prevalence of 2% of all newborns. Although newborn screening programs based on clinical examination with Ortolani and Barlow tests were introduced in the 1950's and 1960's with early abduction splinting of the 2% testing positive, the prevalence of late cases warranting surgery has remained stable, around one per 1000. This has led to the introduction of ultrasound as an additional diagnostic tool, resulting in treatment rates of until 5-6%. This three fold increase in abduction splinting treatment is partly due to the initiation of treatment of infants in whom mild hip dysplasia but no hip instability has been identified. The benefit of early treatment of mild dysplasia in a hip that is neither dislocated nor dislocatable is unclear. Further, abduction splinting is not without risk, with avascular necrosis being reported in around 1%. The investigators conducted a masked, randomized, controlled trial to examine whether mildly dysplastic but stable or instable hips would benefit from early treatment, as compared to watchful waiting.

NCT ID: NCT00578851 Completed - Osteoarthritis Clinical Trials

A Clinical Investigation of the C2a-Taper™ Acetabular System

Start date: April 2006
Phase: N/A
Study type: Observational

The objective of this study is to gather clinical and survivorship information for the C2a-Taper™ Acetabular System, a ceramic-on-ceramic hip articulating system.

NCT ID: NCT00516555 Completed - Clinical trials for Stress, Psychological

EBIS: The Eindhoven Breech Intervention Study

Start date: October 2007
Phase: N/A
Study type: Observational

The purpose of this study is to evaluate whether successful external cephalic version is associated with maternal thyroid function and mood state in pregnant women with breech presentation at term. The relationship between successful external cephalic version and neonatal thyroid function will also be investigated. A possible beneficial effect of successful external cephalic version on the development of congenital hip dysplasia will be evaluated.

NCT ID: NCT00208442 Completed - Osteoarthritis Clinical Trials

A Randomised Single Centre Study to Compare the Long-term Wear Characteristics of Marathon™ and Enduron™ Polyethylene Cup Liners in Primary Total Hip Replacement

Start date: June 1, 2001
Phase: Phase 4
Study type: Interventional

The purpose of this study is to compare the performance and compare the wear characteristics of two polyethylene cup liners, Marathon™ and Enduron™, 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 polyethylene cup liners, Marathon™ or Enduron™ and will be evaluated at regular intervals using clinical and x-ray assessments.
