Active clinical trials for "Hip Dislocation"

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 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.

The aim is to compare QOL and hip specific outcome measures in patients with a single or recurrent episode(s) of THA dislocation and patients with a THA without any dislocation.

The aim is to describe the characteristics of children with cerebral palsy in Denmark. Furthermore, we want to focus on status of the children's hips.

A retrospective study evaluating clinical and radiographic early outcomes of total hip arthroplasty and revision hip arthroplasty with DELTA Multihole TT cup.

Closed reduction is where the thigh bone is placed into the socket without any surgical incision being made. This is more likely to be performed in a child under the age of four year. The femoral head is gently manipulated into the socket, whilst the child is under anaesthetic. Once the femoral head is in place, a hip Spica is applied and can remain in place for up to three months to maintain the hip in the correct position. This allows time for healing and for the socket and the thigh bone to mould together as a joint. The purpose of this study was to identify and evaluate risk factors of avascular necrosis (AVN) after closed treatment for developmental dysplasia of the hip (DDH). assessed according to Salter's classification system.

The aim of this study is to prove the improvement of pubo-femoral distance by early abduction splintage in one-month-old infants with developmental dysplasia of the hip (with a clinical stable hip but an abnormal hip ultrasonography).

The primary objective is to report the true incidence of hip dislocations in primary THA patients within 2 years of index surgery. Secondary, patient and component characteristics (age, sex, comorbidity, cemented/uncemented, approach, head diameter) are analyzed as potential risk factors for dislocation. Specific components may be analyzed based on number.

Acetabular dysplasia often accompanies by acetabular bone hyperplasia and osteonecrosis of the femoral head. These pathological changes can alter the position of the center of the femoral head. Thus, measurement errors will be generated on the anteroposterior radiographs of the adult pelvis involving centre-edge angle, acetabular angle (Sharp angle), and acetabular head index, eventually resulting in the inaccurate diagnosis of acetabular dysplasia. Herein, the investigators describe the protocol to verify three novel X-ray indicators, including offshoring index (OFI), moving up index (MUI) and teardrop baseline offshoring index (TBOI) of the femoral head. All data will be expressed as relative ratios, as the investigators expect to make an accurate diagnosis through avoiding the generation of errors resulting from measurement angles.

Children with cerebral palsy have an increased risk of hip dislocation, which is a painful and severe complication of cerebral palsy. The 20-years evaluation of the Swedish surveillance programme shows that hip dislocation in children with cerebral palsy can be prevented with regular clinical and radiographic examination and early intervention. We would like to determine the individual risk for hip displacement for Danish children with CP in The Danish Cerebral Palsy Follow-up Program. This could be a valuable clinical tool in deciding on further follow-up and treatment.
