Our study shows a broad acceptance of safety devices in leisure sport. A lot of studies have proved the value of helmets to prevent injuries. The introduction of mandatory helmets at least for children and juveniles in alpine sports would be well accepted. Males show a significantly riskier behaviour on ski pistes than females. Efficient controls on ski pistes to avoid ruthless behaviour would be appreciated and declined by equal numbers.
Tibial fractures are still a frequent injury in alpine skiing. Increasing dynamics by means of improved material lead to enlarged forces on the lower extremity. Rotation forces are the major cause of tibial fractures. Therefore it is necessary to adjust the binding to the weight and abilities of the athlete. Also the appropriate choice of the right ski boot is essential. We recommend an internationally standardized marking regarding the flexibility of ski boots to enable the customers to compare the ski boots.
Isolated ruptures of the urinary bladder following minor traumas are a rare abdominal lesion. Diagnosis and treatment are a challenge to emergency physicians and surgeons. This case shows a 46-year-old patient admitted for a minor brain injury after falling during an episode of alcoholic intoxication. Ultrasound and CT scan of the abdomen showed intraabdominal fluid without a parenchymatous lesion. Also a hematuria was significant. The retrograde cystography showed intraabdominal contrast agent. The rupture of the urinary bladder was confirmed by laparoscopy and was intracorporal sutured in double layer technique. Without any postoperative complications the patient was discharged after 4 days. The retrograde cystography after 10 days showed no leckage and the urinary catheter could be removed.
Impaired osseointegration in osteoporotic bone because of increased micromovement is not to be expected in the investigated cementless hip cups as no relevant differences in micromovement were found between normal and osteoporotic bone stock. On the basis of the good clinical results with the Monoblock cup, the upper limit of 100 µ of micromotion for osseointegation in macerated bone is probably set too low.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
