Filter by: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.
Early treatment is considered essential for developmental dysplasia of the hip (DDH), but the choice of screening strategy is debated. The investigators evaluated the effect of a selective ultrasound (US) screening programme. All infants born in a defined region during 1991-2006 with increased risk of DDH, i.e. clinical hip instability, breech presentation, congenital foot deformities or a family history of DDH, were subjected to US screening at age one to three days. Severe sonographic dysplasia and/or dislocatable/dislocated hips were treated with abduction splints. Mild dysplasia and/or pathological instability, i.e. not dislocatable/dislocated hips were followed clinically and sonographically until spontaneous resolution, or until treatment became necessary. The minimum observation period was 5,5 years.
The aim of the randomized controlled trial was to determine whether the addition of a general or of a selective ultrasound screening program resulted in more appropriate criteria for treatment and a reduced prevalence of late DDH compared with clinical examination alone.
Follow up study of patients, who despite periacetabular osteotomy, need a total hip arthroplasty, to see outcome.
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.
This is a retrospective study assessing pre- and postoperative radiographic indices of hip dysplasia in order to identify factors predicting failure following Periacetabular Osteotomy (PAO).
A prospective case-control study of the clinical and radiographic outcome of periacetabular osteotomy in patients with and without preoperative acetabular labral tears.
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.
