View clinical trials related to Hip Dislocation.
Filter by:The study will evaluate the radiographs (x-rays) of 100 patients with a TriFIT total hip at 2 weeks, 3 months, 6 months, 12 months, and yearly following surgery to see if there has been any movement or wear in the hip stem over the course of the study. The study will also record clinical data on each patient using various functional tests and questionnaires at the same intervals.
Between January 1 2006 and December 31 2013, at our department 324 patients underwent hemiarthroplasty (HA) for displaced femoral-neck fracture with a bipolar prosthesis (Variokopf, Link®, Germany) by the use of the posteriolateral approach. Patients with pathological fractures and HA performed with direct lateral approach were excluded. A retrospective cohort study were conducted. Patients with prosthetic dislocation formed one group and patients without dislocation formed the control group. As standard, post surgery radiographs (anteroposterior and lateral) were taken. After these were performed patient started weight bearing as soon as possible. Clinical data regarding patient demographics, details of the surgical procedure and the medical comorbidities were collected by the use of patient and operative records. Radiological analysis with position evaluation was performed using the post surgery radiographs by measuring Wiberg angle, inequality of leg length and femoral offset of the prostheses and compared with non-operated hip joint using the post surgery x-ray images. Our hypothesis were that patients with single- or recurrent dislocations had shortened postoperative leg length, decreased femoral offsed and a Wiberg angle less than 25 degrees.
Aim of the current study is to test the non-inferiority hypothesis of differences in early hip dislocation between a group of patients who will be restricted to sleep in supine position and a group without restricted sleeping position during the first eight weeks after a total hip replacement following a posterolateral surgical approach
Pathogenesis of hip dysplasia Hip dysplasia is multifactorial in origin influenced by genetic and intrauterine factors, such as mechanical (rump presentation and oligohydramnios) and hormonal factors1. To ease the passage through the birth canal, the hip joint is quite mobile perinatally. Postnatally, the laxity of the ligaments will subside and the femoral head will normally position itself deeply in the acetabulum2. The theory is that if the femoral head does not migrate sufficiently into the acetabulum, dysplasia may develop because the matrice to stimulate acetabular growth is not correctly positioned. Normally, at birth the femoral head sits deep in the acetabulum held by surface tension of the synovial liquid. The growth and the hemispherical morphology of acetabulum are dependent on the presence of a normally growing and correctly placed spherical femoral head that works as a convex matrice. If for some reason the normal development is disturbed pre- or postnatally, pathologic relations may develop between the femoral head and the acetabulum3, leading to hip dysplasia. Purpose of this research project is to investigate if the correction of the acetabulum is accurately performed when the surgeon use navigation equipment during PAO.
The purpose of this study is to monitor the performance of the DeltaMotion cup system in the treatment of patients with hip joint disease requiring 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 purpose of this study is to establish whether or not there is a clinical advantage to the use of Aquamantys® System from Medtronic Advanced Energy (formerly Salient Surgical Technologies) in patients undergoing primary total hip arthroplasty via the anterior supine intermuscular surgical approach in terms of blood loss, transfusion and wound healing. Wound healing will be assessed by a blinded observer and based upon a simple and subjective criteria: a) as expected, b) better than expected or c) worse than expected. The blinded observer is experienced in the care of the surgical patient and wound evaluation.
The main objective of this study is to predict cartilage contact pressures in the hip after periacetabular osteotomy (PAO).
The purpose of this study is to 1) evaluate the effectiveness of the Plastizote abduction brace compared to the Pavlik harness in the treatment of developmental dysplasia of the hip (DDH) and 2) compare parent/caregiver satisfaction between the Plastizote abduction brace and the Pavlik harness. The investigators hope to learn which brace treatment is best for a definable population so the appropriate brace can be chosen initially avoiding the time, expense, and frustration of a failed technique.
The purpose of this study is to examine the movement pattern in patients with hip dysplasia preoperative, six and 12 month after minimally invasive approach for Periacetabular osteotomy (PAO). Secondary to examine the movement pattern in patients compared to healthy controls and historical data.
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.
