Carpal tunnel release: a randomized comparison of three surgical methods.

A single-blind, randomized, controlled trial was done to compare the results of carpal tunnel release using classic incision, short incision, or endoscopic technique. In total, 90 consecutive cases were included. Follow-up was 24 weeks. We found a significantly shorter sick leave in the endoscopic group. No significant differences in pain, paraesthesiae, range of motion, pillar pain, and grip strength could be found at 24 weeks of follow-up, although intermediate significant differences were seen, especially in grip strength, in favour of endoscopic technique. No major advantage to using a short incision could be found. There were no serious complications in either group. The results indicate that the endoscopic procedure is safe and has the benefit of faster rehabilitation and return to work.

[Emergency room patients and alcohol consumption]. / Skadestuepatienter og alkoholforbrug.

To investigate the consumption of alcohol among emergency room patients, we included 395 patients above 18 years old entering the emergency room during a period of ten days. The patients completed a questionnaire about alcohol consumption, smoking habits and medication. In our investigation 56% of the men and 25% of the women had a daily consumption above the limits recommended by the Ministry of Health (three drinks daily for men and two for women), while 41% men and 14% women consumed at least five drinks daily or 35 per week. Trauma seen in male patients with high alcohol consumption was characterised by excessive damage to the head, trauma of the lower limb and blows from an object, person or an animal. The alcoholic women were characterised by excessive chemical injuries, incisions and stab wounds, and trauma of the upper limb. In conclusion a surprisingly large amount of emergency room patients can be defined as alcohol abusers and drinking is found to be associated with excessive damage.

Reduction of injuries in downhill skiing by use of an instructional ski-video: a prospective randomised intervention study.

Despite various attempts at prevention, injury in downhill skiing continues to be a worrisome recreational problem. The purpose of this study was to test the effect of an instructional ski video on the behaviour and injuries of 763 downhill skiers. They were enrolled in two study groups, based on whether or not an instructional video had been shown in their bus on the way to a skiing resort. The video focussed on information regarding how to get started in downhill skiing and injury prevention. The outcome parameters, behaviour (binding test and adjustment), injury risk, type and consequence, were registered on the return trip 8 days later by a questionnaire. In the intervention group all outcome parameters changed significantly. The binding test was performed by 86% in the intervention group and by only 59% in the control group (P < 0.05). Adjustment of the bindings was done by 22% in the intervention group vs 14% in the control group. Regarding injury risk, 205 injuries were seen in 158 persons (20.7%) which is 26 injured skiers per 1000 skier-days and 33.6 injuries per 1000 skier-days. In the intervention group 16% of all skiers were injured vs 23% in the control group, yielding a reduction in injury risk of 30% (P < 0.05). Injuries caused by falls were seen in 12.6% in the intervention group vs 16.2% in the control group (P < 0.05). Injuries caused by collision were seen in 6% of the intervention group vs 12% in the control group (P < 0.05). The overall mean injury risk was 16 injuries per 1000 falls. Knee injuries made up 32.6% of the total. For inexperienced skiers the knee injury risk was significantly lower if the bindings had been tested (P < 0.05). Therefore, an instructional ski video can change the behaviour of downhill skiers and reduce the injury risk and consequences significantly.
