BACKGROUND AND PURPOSE Several studies have demonstrated an increased intracapsular pressure in several hip disorders such as septic arthritis, synovitis, and trauma. We therefore measured the intracapsular pressure in different positions in early dysplasic hips and its relation to the concentration of interleukin-1beta (IL- 1beta), the volume of joint fluid, and the clinical and radiographic f...

Surgical management of iliopsoas pathology that fails conservative treatment is controversial. Potential complications following tenotomy include recurrent painful internal snapping, postoperative pain, and hip flexor weakness. Concerns are even greater in dysplastic patients, whom the may play a role as an anteromedial stabilizer. Although data demonstrate arthroscopic for snapping safe effect...

the natural history of an untreated case of a developmental dysplasia (dislocation) of the hip (ddh) associated with multiple congenital abnormalities is reported in a 55-years-old man. the patient’s complaints and the varieties of the typical manifestations emerged in other parts of the body throughout the life are reviewed and discussed as comorbidities of a dysplastic condition. two-stage bi...

INTRODUCTION Revision acetabulum arthroplasty is one of the common procedures, which has been on the rise recently. Many implants are available in the market with variable results. Aseptic loosening is the most common indication for revision acetabulum arthroplasty. Birmingham dysplasia cup has been used occasionally in these complex procedures. We know that these implants have provided good re...

After late reduction of the hip in children with developmental dysplasia the acetabular contour slowly improves and it is difficult to know if and when acetabular reconstruction is required. We studied the radiographs of 19 patients with unilateral dislocated or subluxated hips which had been reduced between the ages of one and two years. Preoperatively, all the affected hips showed acetabular ...

Several studies have documented the failure of neonatal clinical screening to reduce the incidence of hip dislocation later in infancy. In addition, the practice of splinting unstable hips is said to result in the treatment of many infants who would have developed normally if left unsplinted. Ultrasound provides a detailed image of the bony and cartilaginous neonatal hip. The results of convent...

Dysplasia of the human hip is characterised by insufficient anterolateral covering of femoral head by the acetabulum. In our study, we evaluated dysplastic human hip joints using biomechanical parameters (the peak contact stress in the weight-bearing area of the hip - pmax) and X-ray image parameters (the centre-edge angle - thetaCE, the transverse acetabular inclination angle - thetaUS, the ac...
