BACKGROUND Six acute traumatic hip dislocations in pediatric patients were retrospectively analyzed. Types of dislocations, associated lesions, treatment methods, complications, and clinical and radiological outcomes were reviewed. METHODS Six child patients treated due to traumatic hip dislocation between 2007 and 2011 in our clinic were included in the study. While five of the patients were...

for total hip arthroplasty have become popular over the past few years. However, the shorter incision leads to higher soft-tissue tension, increasing the chances for dislocation. We describe the case of a woman who underwent total hip arthroplasty by a minimally invasive variation of a common arthroplasty procedure and suffered dislocation of the femoral component from the acetabulum into the p...

The extra-articular impingement of the greater trochanter against the ileum is an underrated cause of early dislocation in total hip arthroplasty. In this preliminary study, the authors assess the effectiveness of an anterior longitudinal osteotomy of the greater trochanter for preventing dislocation. A total of 115 patients underwent a total hip arthroplasty through a posterolateral approach. ...

Only two cases have been reported of congenital dislocation of the hip in infants born after extrauterine pregnancies. We report a further two and discuss the management and the variable outcome. These cases seem to confirm that congenital dislocation of the hip is associated with moulding forces rather than being a teratological abnormality.

The umbilical cord was employed as a source of collagen in 10 children with congenital dislocation of hip. The amount of collagen and its solubility were measured in slices of the cords and in the umbilical veins and compared with the values in normal subjects. Both the amount of collagen and its solubility were decreased in children with congenital dislocation of the hip.

We used a large prospective institutional registry to determine if there is a 'safe zone' that exists for acetabular component position within which the risk of hip dislocation is low and if other patient and implant factors affect the risk of hip dislocation. Patients who reported a dislocation event within six months after hip arthroplasty surgery were identified, and acetabular component pos...
