Rotational acetabular osteotomy (RAO) 4) is an interventional strategy that seeks to reduce the abnormal high stress concentra...

A 10-year-old girl with Apert syndrome underwent a Le Fort III osteotomy with the positioning of internal and external distraction devices. The operation was straightforward with no intraoperative complications. Very soon after completion of surgery an anisocoria (unilateral dilation of a pupil) was noticed. This was followed by intracranial oedema which was fatal. The aetiology was dissection ...

We reviewed the results of 277 intertrochanteric valgus-extension osteotomies performed between 1973 and 1975 for primary or secondary osteoarthritis. The average age of the patients was 51 years and follow-up varied from 11 to 15 years. At the latest evaluation 67% of the hips were good or excellent on the Merle D'Aubigné scale. Better results were obtained in patients under 40 years of age wi...

INTRODUCTION Periacetabular osteotomy (PAO) is an effective joint-preserving procedure for young adults with developmental dysplasia of the hip. Although PAO provides excellent radiographic and clinical results, it is a technically demanding procedure with a distinct learning curve that requires careful 3D planning and, above all, has a number of potential complications. We therefore developed ...

Once used routinely, trochanteric osteotomy in total hip arthroplasty now is usually limited to difficult primary and revision cases. There are three types: the standard trochanteric osteotomy and its variations, the trochanteric slide, and the extended trochanteric osteotomy. Each has unique indications, fixation techniques, and complications. Primary total hip arthroplasty procedures requirin...

BACKGROUND The treatment of middle-aged patients with periacetabular osteotomy remains controversial. The goal of the present retrospective study was to analyze the intermediate to long-term functional and radiographic results of periacetabular osteotomy in patients below and above the age of forty years. METHODS Between February 1990 and December 2004, 166 periacetabular osteotomies were per...

The aim of this study was to determine the vertical and anteroposterior alterations in the soft, the dental and the skeletal tissues associated with the facial profile after Le Fort I maxillary impaction in conjunction with sagittal split osteotomy for mandibular advancement performed in patients with a high angle Class II skeletal deformity.The study population consists of 21 patients (11 fema...

Les transformateurs de prédicats ont été introduits par Dijkstra et ont permis de fonder la théorie des preuves de programmes et la théorie de l’affinement des systèmes d’actions. Ce texte analyse le lien existant entre les transformateurs de prédicats et les systèmes d’actions affinés. Les hypothèses d’équité sont prises en compte et une uniformisation de la présentation permet de démontrer le...

Surgical maxillary repositioning in individuals with vertical maxillary deficiency may be accompanied by skeletal instability. Long-term skeletal changes in 13 patients who underwent a Le Fort I downsliding osteotomy were studied retrospectively. Nine patients underwent a single-jaw procedure, and 4 patients underwent a bimaxillary procedure. Rigid fixation was used in 10 patients, and wire ost...
