[This website - shoes and life] approaching summer, dressed in a "tap, tap" sound of dragging people to a cool feeling, stylish and comfortable flip flops become a must-have item for young people summer. However, the Shanghai Railway Administration recently issued a micro-blog reminder that wearing a flip flop is harmful and counts out its “seven sinsâ€: it causes pain in the back heel, arches and toes; it causes strain on the toes and even nerves in the tendon; it can easily cause sprained muscles in the calf muscles. And plantar fasciitis; hardened skin and chapped heel; causing hip and lumbar pain; the feet more vulnerable to trauma; lack of protection of the toes, but also lead to severe pressure fracture of the phalanx. Earlier, it was reported that wearing a flip flop movement can cause rupture of the Achilles tendon, knee joints, waist, buttocks, and injury to the spine. What's the fear of wearing flip flops, which can lead to the injury of human bones? What kinds of hazards may be hidden when wearing flip flops? Under what circumstances need treatment? What should you pay attention to when choosing shoes? Which people are not suitable for wearing flip-flops? Medical guidance / Dr. Xiao Jin, Head of the Department of Foot and Ankle Surgery, Orthopaedic Hospital of Guangzhou General Hospital of Guangzhou Military Command answered the question.
Weibo rumors: wearing flip-flops can cause phalangeal fractures? rare!
In recent days, Weibo has suggested that in the “five crimes†of flip flops, due to the lack of protection of the toes, the flip flops can also lead to severe pressure fractures of the phalanges.
In this regard, Dr. Xiao Jin, head of the Department of Foot and Ankle Surgery, Orthopaedic Hospital of Guangzhou General Hospital of the Guangzhou Military Region stated that the 'phalangeal pressure fracture' in microblogs should be 'stress fracture of the phalanges'. "Stress fracture" refers to a fracture that develops over a long period of time due to long-term weight-bearing or excessive exercise. It is also called a fatigue fracture or a march fracture. The most common site for stress fractures is the sacrum, not the phalanx. “But the current academic literature in China does not find that the flip-flop will cause stress fracture of the phalanges. In principle, it can be introduced that due to the lack of support of the arch, strains are caused and stress fractures are caused; but this is actually a very extreme case. Life is not rare and rare, and it may even have exaggerated ingredients."
Previous reports also pointed out that long-term wear of flip flops can cause rupture of Achilles tendons and hip involvement. Xiao Jin believes that "Achilles tendon rupture" and "phalangeal fracture" are rare in clinical practice and are extreme cases. As for "hip to the buttocks," it is also specious, "accurately speaking, it should be the result of fatigue in the pelvic and spinal muscles."
Hazard: 1/6 heel pain related to wearing flip flops
“Although the use of flip flops is well received by everyone, wearing flip flops will change the point of force when the person stands upright, resulting in an unbalanced force on the feet.†Xiao Jin explained that when a person stands upright, he is forced by 3 points: Heel, 1st metatarsal head, 5th metatarsal head. The normal foot has a foot arch on the medial side, and the arch can ensure three-point force balance. It plays an important role in protecting the structure of tendons, ligaments, and blood vessels of the plantar foot, cushioning pressure, and adapting to uneven ground. If the foot arch is too low to cause a flat foot, or if the foot arch is too high to form a high bow foot, the force of the foot will be unbalanced and pain and deformity will occur easily.
"The most common hazard of flip-flops is heel pain, followed by flat feet. Among the patients with heel pain, 1/5 to 1/6 are related to wearing flip-flops." Xiao Jin said that wearing long flip-flops , there will be some of the following hazards:
1. Heel pain
When walking normally, the body tends to lean forward. However, due to the fact that the sole is flat and the center of gravity of the shoe is moved backwards, the flip flops are too thin to effectively absorb the recoil of the ground. The plantar fascia or fat pad is vulnerable to impact, resulting in severe heel pain. Heel bone spurs will appear.
2. Can not support the arch, resulting in flat feet
Most flip flops are too thin, too flat and too soft to give strong support to the arches. Wearing for a long period of time can also easily cause leg and local muscle strain. In the period of growth and development of children and children wearing too much, it may also form a flat foot deformity.
3. Toe deformity, forming a claw toe
Flip-flops rely on only two thin straps to connect shoes and feet. When walking, the forefoot and toes will be subconsciously strained to buckle the soles of the shoe due to concerns that the shoes will be removed. For a long time, it can cause toe muscle spasm, chronic inflammation, and severe formation of paws.
4. Joint aging and pain in the lower back and lower limbs
If the bottom of the shoe is flat, people tend to lean back. When swiftly walking, the body's center of gravity tends to lean forward, so that the knee will naturally bend, and the muscles in the pelvis's waist will also change to adapt to this change. Also, when wearing a flip-flop, the pace is often short and the pace is fast, which accelerates the wear of lower limb joints. Especially in the elderly, long-term wearing may result in fatigue of the knee, pelvis, and spine muscles, degeneration of the lower back and knee joints, ankle joints, bone hyperplasia, and pain.
5. The skin becomes hard and the feet are easily injured
The feet are exposed for a long period of time, and the summer sun exposure can easily make the skin of the feet dry, aging, and even cleft.
Treatment: Heel pain does not improve for half a year
"Heel pain is related to improper shoes, too much walking, and the degeneration (ageing) of the person's plantar fascia. Most of the heel pain is a self-limiting disease. It usually gets better and heals itself in about half a year. Intractable, repeated attacks of heel pain, will go to the hospital for treatment." Xiao Jin said so.
Patients with milder symptoms should first exchange a pair of suitable shoes. The best choice is sports shoes. In addition, physical therapy can be performed, such as hot foot bath, foot massage; or physical therapy such as ultra-short wave, shock wave.
In severe cases, drug treatment, functional exercise and bracing are required. Drug treatment includes anti-inflammatory analgesia, blood circulation, and placement of a small drug packet made of ground Chinese medicine at the pain point (heel) to relieve symptoms. Functional exercise is mainly stretching the ankle. As for brace treatment, it includes night splints and customized insoles to keep the ankles taut, dorsiflexed.
Protection: Elderly children should not wear flip flops
Xiao Jin reminded adults that it is not recommended to wear flip flops for long periods of time. Each time it is best not to exceed 1 hour. In addition, the elderly and children should not wear flip flops. This is because the use of flip flops will increase the joint wear of older people, and it is easy to fall and cause fractures. Children, on the other hand, are prone to deformed flat feet. In addition, people with foot problems such as flat feet, unstable ankle joints, stomping feet, and pregnant women do not recommend wearing flip flops. When exercising, climbing, or traveling, you may walk to a hard and uneven path and you should not wear flip flops. And some white-collar workers are used to putting a pair of drags in the office to ease the fatigue of wearing high-heeled shoes. Xiao Jin reminded that due to the smoothness of the tiles in office buildings, it is important to pay attention to the prevention of wrestling.
How to choose the right shoes? Xiao Jin trick: "The correct shoes should be designed to be about 3 to 5 cm high heel, hard bottom cushion, wrapped in the back of the foot, arch support shoes. Do not choose those who fold Soft, shoe that can be twisted on the sole. If you want to wear flip flops, it is recommended to choose a flip-flop with a wider heel strap and a slightly higher heel.
Xiao Jin also introduced that usually at home can ease the heel pain relief health care methods. In addition to using hot water to soak your feet, or perform foot massage, and press the foot arch more often, you can also use your foot to gently squash a small ball (such as tennis ball), use the sole of your foot to gently roll the ball, massage and stimulate The point of the arch can also reach the purpose of stretching the calf muscles.
