BACKGROUND The natural history of hip instability (without subluxation or dislocation) and treatment in infants remain controversial. We performed a retrospective cohort case-only study with blinded, prospectively collected data to assess normalization of the acetabular index in consecutive untreated infant hips with sonography instability. METHODS Consecutive hips meeting inclusion criteria ...

Failure of total hip arthroplasty with acetabular deficiency occurred in 55 patients (60 hips) and was treated with acetabular revision using morsellised allograft and a cemented metal-backed component. A total of 50 patients (55 hips) were available for clinical and radiological evaluation at a mean follow-up of 5.8 years (3 to 9.5). No hip required further revision of the acetabular component...

We conducted this animal study to demonstrate whether exposing the acetabulum in immature rabbits to extracorporeal shock waves induces bone formation in the acetabulum. Five thousand shock waves of 100 MPa each were directed, from outside, at the acetabular roof of eight immature rabbits. At each of two time points (4 and 8 weeks) after treatment, the pelvises of four rabbits were removed and ...

We carried out a morphometric analysis of acetabular dysplasia in patients with cerebral palsy requiring hip surgery using three-dimensional CT. We evaluated 54 hips in 27 patients. The contralateral normal hips of ten patients with unilateral Perthes' disease were used as a control group. The acetabular defects were assessed qualitatively as anterior, posterior or global. Quantitative assessme...

INTRODUCTION Acetabular fractures are a common problem among young males. An acetabular fracture with disruption of the joint surface, if untreated, will rapidly lead to post-traumatic osteoarthritis. Proper reduction and internal fixation depend on accurate classification and the quality of imaging. CASE PRESENTATION We present an unusual form of acetabular fracture, which is not included in...

We describe a modified surgical technique for the reconstruction of major acetabular defects using a coned acetabular component (the Stanmore 'ice-cream' cone prosthesis) and report its early clinical outcomes. A single surgeon performed 28 acetabular reconstructions using a stemmed-cone acetabular prosthesis (mean age 70.9 years; 61% female) in 15 oncology patients with periacetabular metastas...

INTRODUCTION Open reduction and internal fixation (ORIF) is standard care for most acetabular fractures. With increasing numbers of acetabular fractures in the elderly, the risk of revision surgery and conversion to total hip replacement (THR) is increasing. Alarmingly, about 20-25% of acetabular fractures in the elderly following ORIF needed revision and conversion to delayed THR. METHODS Re...

BACKGROUND Loosening of acetabular components often leads to bony defects. Management of extensive acetabular bone loss in hip revision arthroplasty can be a tremendous challenge. QUESTIONS/PURPOSES We asked whether a reconstruction with impacted bone grafts will provide a durable and pain-free function in extensive acetabular defects. We specifically determined the (1) survival rates with th...

Background:Management of acetabular fractures in the senior population can be one of the most challenging injuries tomanage. Furthermore, treating surgeons have a paucity of information to guide the treatment in this patient population.The purpose of this study was to determine: (1) demographic and epidemiologic data, (2) mortality rates for nonoperativecompared to operative management at diffe...

INTRODUCTION In case of severe post-tuberculosis osteoarthritis of the hip, arthrodesis, excision arthroplasty, or total hip arthroplasty may be considered. The latter can be challenging, because destruction of the joint, and most importantly the acetabulum, is frequently seen. To fill up acetabular bone stock loss during total hip arthroplasty, there is the possibility to use bone auto-grafts ...
