HIPS-2 is a set of image processing modules which provides a powerful suite of tools for those interested in research, system development and teaching. In this paper we first review the design considerations used to develop HIPS-2 from its predecessor (HIPS'). Then, a number of further developments are outlined which are under consideration. These include the development of a graphical user int...

Femoroacetabular impingement causes pain in the hip in young adults and may predispose to the development of osteoarthritis. Genetic factors are important in the aetiology of osteoarthritis of the hip and may have a role in that of femoroacetabular impingement. We compared 96 siblings of 64 patients treated for primary impingement with a spouse control group of 77 individuals. All the subjects ...

PURPOSE To report mid-term results of total hip arthroplasty (THA) using the Opti-Fix Plus Hip System (Opti-Fix Hip), and to assess the correlations between peri-implant bone changes and the distal medullary occupancy rate. METHODS 11 men (13 hips) and 53 women (58 hips) aged 24 to 87 (mean, 61) years underwent THA using the Opti-Fix Hip, with a modular stem and a distal sleeve, and were foll...

BACKGROUND Biomechanical parameters of the hip have been suggested to have an important influence on the development of osteoarthritis. We aimed to find out whether higher stress is generated in a hip that subsequently results in earlier hip arthroplasty compared to the contralateral hip in the same subject. METHODS Standard anterior-posterior pelvic radiographs with no or subtle radiological...

OBJECTIVE To evaluate the clinical and radiological medium-term results from surgical treatment of developmental hip dysplasia through Salter innominate bone osteotomy and Ombrédanne femoral shortening. METHODS Fourteen patients were evaluated, with surgical treatment on 18 hips (seven right-side hips and eleven left-side hips) using the proposal technique, performed between 1998 and 2008. Th...

BACKGROUND Although little is known, a limited number of three-dimensional computed tomography (CT) images of the pelvis present focal concavity of posterior superior acetabulum. The purpose of the present study was to investigate this morphologic deformity and its relation with dysplasia and retroversion in adults who were expected to have the original morphology of the acetabulum after growth...
