BACKGROUND-Mortality is increased after a hip fracture, and strategies that improve outcomes are needed.
Background: Limited knowledge exists on injuries among professional alpine skiers. Objective: To describe the risk of injury and the injury pattern among competitive World Cup alpine skiers during the competitive season. Methods: Retrospective interviews were performed with all World Cup athletes from 10 nations at the end of the 2006-7 and 2007-8 winter seasons, and all acute injuries occurring during the 4.5-month competitive season were recorded. If the athlete was not present, their coaches or medical personnel were interviewed. Results: A total of 191 acute injuries were recorded among 521 World Cup alpine skiers. As many as 86 injuries (45%) occurred during World Cup/World Ski Championship competitions, corresponding to an injury rate of 9.8 injuries per 1000 runs (95% CI 7.8 to 11.9). The injury rate was found to increase with increasing speed (slalom 4.9 injuries per 1000 runs, 95% CI 2.5 to 7.4-giant slalom 9.2, 5.1 to 13.3-super-G 11.0, 5.2 to 16.8-downhill 17.2, 11.6 to 22.7). The most frequently injured body part was the knee, with 68 injuries (36%), and 37 of these were severe. The overall injury rate was higher in males than in females, but not for knee injuries. Conclusions : The risk of injury among World Cup athletes in alpine skiing is even higher than previously reported. The knee is the most commonly injured body part and with many severe injuries. Injury rate increased with a higher speed and was higher among males than in females. While the injury risk for recreational skiers has been well documented based on prospective injury recording systems since the early 1970s, 1-3 there are almost no data published on the injury pattern and injury risk for competitive alpine skiers. Recent data on professional skiers competing in diverse disciplines from downhill with high speed, long jumps and minimal protection to slalom with technical demands are limited to two single-event studies (Olympic Games 1994 and Junior World Championships 1995).4 5 However, several crosssectional studies among active skiers have shown that 72-83% of world class skiers have sustained at least one previous serious injury. [6][7][8][9] Although these studies are decades old, they indicate that the risk of injuries is high.The aim of this study was therefore to describe the risk of injury and the injury pattern among competitive World Cup alpine skiers during the competitive season. METHODS Study design and populationWe conducted retrospective interviews with World Cup alpine skiers from 10 nations at the end of the 2006-7 and the 2007-8 winter seasons because a methodological study 10 found this to be the best method available to record injuries among World Cup ski and snowboard athletes. We defined the winter season as starting on 1 November or, if earlier, the first World Cup race of the season, lasting until the interviews took place. For the 2006-7 season, the first World Cup alpine event was in Levi, Finland on 11-12 November. The first races scheduled in Sölden, Austria 28-29 October were cancelled because o...
Hemiarthroplasty is the most commonly used treatment for displaced femoral neck fractures in the elderly. There is limited evidence in the literature of improved functional outcome with cemented implants, although serious cement-related complications have been reported. We performed a randomized, controlled trial in patients 70 years and older comparing a cemented implant (112 hips) with an uncemented, hydroxyapatite-coated implant (108 hips), both with a bipolar head. The mean Harris hip score showed equivalence between the groups, with 70.9 in the cemented group and 72.1 in the uncemented group after 3 months (mean difference, 1.2) and 78.9 and 79.8 after 12 months (mean difference, 0.9). In the uncemented group, the mean duration of surgery was 12.4 minutes shorter and the mean intraoperative blood loss was 89 mL less. The Barthel Index and EQ-5D scores did not show any differences between the groups. The rates of complications and mortality were similar between groups. Both arthroplasties may be used with good results after displaced femoral neck fractures.
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.
