OBJECTIVE: The Stoppa approach in its modified form is an intrapelvine approach for the treatment of acetabular fractures. It is an alternative to the ilioinguinal approach. Goals are the gentle soft-tissue preparation, anatomic reduction and stable internal fixation. Here, the approach is described in detail together with possible expansion possibilities. INDICATIONS: The Stoppa approach in particular is used for the treatment of fractures of the anterior column with participation of the quadrilateral surface, transverse fractures, T-type fractures, but also 2-column fractures when the main pathology is located in anterior portions of the acetabulum...

BACKGROUND: Various attempts have been made to assess the inclination angle of the acetabulum utilizing new imageprocessing technologies to enable three-dimensional reconstruction of the acetabulum. However, reliability of these methods has not been estimated in comparison with anatomical measurements. This study developed a geometric method for measuring the acetabular inclination with radiograms and evaluated the reliability of this method by comparing the anatomically measured acetabular inclination angle of the same dry pelvic bone...

PURPOSE OF THE STUDY: The key problem of implant fixation in THR is stress distribution, i.e. load transmission between bone and implant. The closer the load transfer is to the original physiological situation, the easier the adaptation of the periprosthetic bone to the new biomechanical conditions after implantation of the cup and the safer is its longlasting fixation. The aims of the studies were 1) to get information about the physiological load transfer in the normal hip joint, 2) to get information about the load transfer between acetabulum and acetabular sockets and vice versa, 3) to measure the periacetabular pelvic bone deformation as the stimulator of the remodelling process (third stage of osseointegration) in the normal hip joint and in hip joints fitted with different acetabular cups, 4) to study the morphological stages of osseointegration of a non-cemented press-fit cup and to compare the morphological structure of the periacetabular bone with the biomechanical data obtained by the in vitro studies and finally, 5) to compare the clinical and radiological outcome of follow-up studies of the senior author's "Press-Fit cup" with the theoretical hypotheses according to the experimental observations...

OBJECTIVE: To determine the long-term effects of juvenile pubic symphysiodesis (JPS) in dysplastic puppies. STUDY DESIGN: Prospective, randomized, clinical trial. ANIMALS: Seven dysplastic Chesapeake Bay retrievers and 2 beagle-crosses (BX1 and 2). METHODS: Five puppies had JPS performed with electrocauterization at 12, 16, 20, 22, and 24 weeks of age, respectively. Two puppies served as controls. BX1 and BX2 were used to obtain biopsies of the symphysis...

The sacroiliac region is the link through which the weight of the trunk is transmitted to the legs and a region frequently indicated by patients as the site of back pain. Sacral fractures often remain undiagnosed and untreated and frequently result in neurologic symptoms and deficits. Since a systematic approach is used to analyse the pelvic ring fractures with CT scans, the surgical management of sacral fractures had become a focus of interest. Stabilization is important for survival of the patient and may improve the long-term functional results of treatment of such injuries...

This report documents our limited experience with total hip replacement requiring large bone-graft reconstruction of the acetabulum with internal fixation. Four of the 14 patients were elderly and had a fresh fracture of the acetabulum; 6 had severe loosening of the acetabular companent with non-union, necessitating plate fixation along the pelvic rim in 5 patients. Four patients had large defects after tumor resection. In only 1 of these 14 cases did loosening occur. Our results are promising and we plan to increase the use of pelvic plates in these extremely unstable cases...
