Filter by:It has been postulated that use of a larger femoral head could reduce the risk of dislocation after total hip arthroplasty, but only limited clinical data have been presented in third generation alumina bearings. The purpose of this study is to evaluate the effect of femoral head size for total hip arthroplasty using third generation alumina bearings on the joint stability and clinical results. The investigators hypothesized that larger ceramic head group has a similar rate of dislocation and clinical results in smaller ceramic head group.
The aim is to determine if the use of infiltration with an adrenalin solution in the operative field of Total Hip Arthroplasty (THA), allays a significant reduction of the cumulated volume of bleeding (pre and post operative) without increasing the per and post operative risks. At the same time, the effect on the post operational pains is evaluated.
The purpose of this study is to demonstrate survivorship of the femoral stem at 5 years.
The purpose of the Post Approval Study of the ABC and Trident® systems is to continue to demonstrate the safety and efficacy of the alumina-on-alumina bearing surfaces combined with the appropriate shell in a cementless application.
The primary objective of the study is to demonstrate the linear wear rates of the Trident® X3 polyethylene insert are superior to a polyethylene control group wear rate at 5 years postoperative. This measurement will be evaluated by comparing digitized images of serial radiographs obtained over a follow-up period of 5-years.
The purpose of this study is to evaluate clinical and radiographic outcome data in patients implanted with the Accolade® TMZF® femoral stem.
It has been reported that the operative approaches have an effect on clinical outcome in total hip arthroplasty. The purpose of this prospective study was to compare clinical and radiological outcomes between anterolateral approach and posterolateral approach in total hip arthroplasty.
The purpose of this study is to evaluate the efficacy and safety of various doses of YM150 (the experimental drug) compared to enoxaparin in the prevention of venous thromboembolism in patients that are undergoing elective hip replacement surgery.
The study is a prospective, controlled, randomised and assessor blind study that investigate if the need for bank blood transfusion could be reduced in patients, undergoing primary or revision total hip replacement surgery, who receive their own blood back with the medical device Sangvia. A comparison in need for bank blood will be made between patients that either receive their own blood back or not.
Rehabilitation plays an important part after total hip arthroplasty. In this common practice few studies have been performed on this issue. The aims of this study were: 1. to examine the immediate effects of a walking skill training program on walking, stair climbing, balance, self-reported physical functioning physical functioning, pain and self-efficacy compared to a control group without supervised physiotherapy 2. to examine whether the effects persisted 12 months after surgery
