Skiing danger？ This is actually a misunderstanding, please put away the raiders.
The Beijing Winter Olympics is still in full swing. See if you are not addicted after all, or do it-put on skates and snowboards, and feel the thrill of speeding down on the ice or snow, which is the most enjoyable moment for ice and snow enthusiasts.
However, any sport is fun and dangerous, and ice and snow sports are no exception.
Damage is not divided into novice and expert.
Xiao Jing and his friend Lao Wu went skiing. Because Xiao Jing usually skied less, he has been leading and protecting Lao Wu to slide down the primary road. By the last slide, everyone was tired, but Lao Wu felt it was a pity that he hadn’t skated the advanced road yet, so he went to the advanced road. Xiaojing didn’t rest, and he continued to slide the primary road …
Coincidentally, both of them accidentally fell down. Xiao Jing said that he was too tired, and there was no one to guide him. He just felt that there was something wrong with his movements when he started sliding, and he soon hit the guardrail. Lao Wu, who has several years of skiing experience, sprained his knee after falling because he was too fast on the advanced track and didn’t do enough corner movements.
After examination, Xiao Jing’s knee was slightly sprained, but Lao Wu, who has more skiing experience, was injured more seriously because of too fast, and the anterior cruciate ligament of his knee was broken, so he had to undergo arthroscopic reconstruction.
The situation of Xiao Jing and Lao Wu is very common on the snow field. In the snow season of 2017-2018, the number of skiers in Yanqing Ski Resort in Beijing reached 297,000, and 428 people needed emergency treatment due to injuries, of which 61 people needed to be transferred to hospital for treatment. There have also been cases of death caused by skiing accidents in China.
90% of "Ice Man" is a novice.
90% of ordinary ice and snow sports fans in China are beginners, and most of them have not received professional guidance from regular coaches and have not fully mastered skiing skills. When an emergency happens, due to the lack of sufficient coping experience and skills, people often panic and mishandle, which leads to their own injuries or injuries to others.
Although some people have several years of experience in ice and snow sports, they are blindly confident and choose to slide on the snowy road that does not match their ability; Even some experienced skiers blindly challenge difficult skiing movements in pursuit of excitement, pursue the pleasure of flying down, leave safety behind and eventually fall into pain.
When doing ice and snow sports, what conditions are likely to lead to sports injuries?
01 Lack of risk awareness
Most ordinary ice and snow lovers are not fully aware of the dangers of this sport and are not fully prepared for the potential risks. The correct way is to participate in ice and snow sports with good mental state and high concentration.
02 technical action is not standardized
Mastering the correct basic technical movements is the premise to avoid injury accidents.
03 insufficient preparation activities
Most people don’t have the good habit of warming up and doing adequate preparatory activities before exercise, and don’t realize that warm-up exercise is an important means to reduce sports injuries. In the cold outdoors, due to the influence of low temperature, great changes have taken place in muscle expansion and contraction function, cardiopulmonary adaptation, blood circulation and joint flexibility. Warm-up and warm-up activities have a strong protective effect on human body, especially joints, which can increase muscle temperature, lengthen muscle fibers, increase joint flexibility, improve the functions of various organs and tissues of the body, make the human body enter the exercise state faster and more smoothly, and reduce the occurrence of sports injury accidents.
04 Too much exercise and too long time.
First of all, excessive exercise can easily lead to muscle fatigue, leading to the deformation and irregularity of skiing movements, and then accidents, ranging from muscle ligament damage to fracture and even vascular nerve damage; Secondly, long-term excessive exercise will lead to joint and muscle strain.
05 failed to replenish energy in time.
During skiing, the body consumes a lot of energy, so we must pay attention to supplementing nutrition and energy, never continue to exercise in poor physical condition, and avoid taking part in strenuous skiing during diet control or "weight loss". Good physical fitness is maintained by adequate nutrition. Without good physical fitness as a guarantee, any beautiful skiing skills are difficult to show.
If the above mistakes can be avoided, ice and snow sports are actually not dangerous.
Skiing and first aid.
In mass ice and snow sports, knee joint injury ranks first, ankle joint injury and shoulder joint injury rank second. Most people who go to the sports medicine department of the hospital to see the emergency department have these kinds of injuries.
The most common knee injuries are medial collateral ligament rupture, anterior cruciate ligament rupture, meniscus tear, patella dislocation, etc. Ankle injuries are mainly ankle lateral collateral ligament tears and ankle fractures caused by ankle sprain.
The posture of tumbling and suddenly falling on one’s back during skiing may cause injuries to the head and neck, lumbar vertebrae and sacrococcygeal vertebrae.
Fracture is also a common sports injury, and the most common parts are wrists, ankles, knees, lumbar vertebrae and cervical vertebrae.
In addition, although joint dislocation and cutting injury are not universal, the harm is enormous.
Let’s talk about the common types of ice and snow sports injuries and suggestions for treatment.
01 meniscus injury of knee joint
Torsion of knee joint can cause meniscus tear and ligament rupture, and the injured person will have obvious symptoms such as knee joint pain, swelling and limited movement, and in severe cases, the joint will not be straightened. It is suggested to consult a sports medicine doctor in a big hospital as soon as possible. Many people may need arthroscopic surgery.
Fracture of anterior cruciate ligament of knee joint
When falling on the ice and snow, if the strength of spraining the knee joint is relatively large, it may lead to the injury of the medial collateral ligament and the rupture of the anterior cruciate ligament. Once the anterior cruciate ligament breaks, the knee joint will be severely painful and the joint will swell up. If you endure it, it will lead to instability of the knee joint. Generally, arthroscopic auxiliary surgery is needed to rebuild the cruciate ligament. It is recommended to seek medical treatment as soon as possible, and find a specialist to make a clear diagnosis and determine the treatment plan.
03 medial collateral ligament rupture of knee joint
The medial collateral ligament injury mostly occurs when the knee joint is slightly flexed and the calf is suddenly everted. After the medial collateral ligament is broken, the medial knee joint is swollen, local pain and subcutaneous congestion. If the swelling of the medial side of the knee joint is particularly serious, and besides the obvious tenderness of the medial side of the knee joint during physical examination, the opening feeling is also very obvious, then it can basically be diagnosed as a complete rupture of the medial collateral ligament, which may be accompanied by anterior cruciate ligament injury. If it is not completely broken, you can not do surgery, conservative treatment with long leg plaster knee flexion 30 inversion (preferred) for 3~4 weeks, and then change the adjustable chuck support; Or a movable support with a chuck is fixed for 6-8 weeks; If MRI shows that the deep and shallow layers are completely broken, or even some ligaments have been embedded in the joint space, emergency surgery is needed.
04 ankle sprain
The incidence of ankle sprain is very high, which is generally varus injury, which is easy to cause ligament damage of the lateral ankle, and severe ankle sprain will cause ankle fracture.
After on-site treatment of ankle sprain, you should seek medical advice in time. It is best to go to a professional department in a big hospital, such as sports medicine or ankle surgery. It is best if you can find a doctor who specializes in foot and ankle in sports medicine. The doctor will give a more reasonable treatment plan according to the severity of the injury, which is conducive to the follow-up rehabilitation of patients. Surgical treatment is the first choice for patients with lateral collateral ligament of ankle joint combined with joint capsule tear, especially for athletes and young people who like sports. Ligament rupture is serious, or for ankle fracture, conservative treatment, emergency operation or delayed operation should be chosen according to the specific type and severity of the fracture.
