INTRODUCTION Recurrent dislocations of hip replacements are a difficult challenge. One treatment option for recurrent dislocations is the use of a dual mobility cup. The aim of this study was to retrospective investigate the effect of dual mobility cups as a treatment for recurrent dislocations in a consecutive series. Materials and. METHODS 56(More)
Total hip arthroplasty (THA) as primary treatment for displaced femoral neck fractures is controversial as THA is associated with higher rates of dislocation but lower rates of re-operation compared to hemiarthroplasty (HA). A dual mobility cup (DMC) design is associated with lower dislocation and re-operation rates in elective surgery. Is this also the(More)
Thirty-one patients admitted with the first bleeding episode from oesophageal varices were randomized in a double-blind manner to receive oral propranolol, 160 mg daily, for 6 months (n = 15) or matching placebo (n = 16) for the same period. Endoscopy was performed each month during the 6 months and additionally after a further 3 months. The oesophageal(More)
The plasma clearance and extraction ratio of indocyanine green (ICG) were followed in cats anesthesized with chloralose. In one series of experiments the ICG infusion rate was raised stepwise and in another the hepatic plasma flow was changed by replacing part of the blood volume with erythrocytes, plasma, or dextran (Macrodex). For unknown reasons blood(More)
A total of 87 femoral exchange revision procedures were performed in 80 patients. Mean follow-up time was 3.6 years. Patients were followed prospectively. At follow-up, 5 patients had died, and 74 (93 %) completed follow-up. Results were evaluated on the basis of incidence of re-revisions and other complications, patient satisfaction, and preoperative and(More)
Acute prehepatic portal hypertension was mechanically induced in Göttingen minipigs. A 125% increase in portal pressure resulted in a significant decrease in estimated hepatic blood flow. The decrease in blood flow was accompanied by a 25% reduction in the 'true' clearance of indocyanine green and an 18% decrease in splanchnic oxygen consumption. Judged(More)
In 10 Göttingen mini-pigs esophageal varices developed after banding of the portal vein. In five pigs the varices were treated by paravariceal injection of polidocanol, and the rest served as controls. As judged from endoscopy and portography, the varices disappeared after four sclerotherapy sessions within 4 weeks, and at the same time portal venous(More)
Portal venous hypertension was induced in Göttingen minipigs by banding the portal vein. The pigs were checked repeatedly during the following 24 weeks. Portal pressure increased immediately on banding, from 8.4 +/- 0.7 mm Hg to 19.4 +/- 0.7 mm Hg, and remained constant throughout the observation period. Within 5 weeks all pigs developed esophageal varices,(More)
17 acetabular revisions (16 patients) were performed for recurrent dislocations. 14 patients were examined clinically and radiographically after mean 3 (1-8) years. We found malpositions of components in 12 of 17 cases. 8 of 17 had redislocations and 2 were rerevised. Harris hip scores improved from 57 to 70. 10 of 14 patients were satisfied with the(More)
