Is it normal for boys to have x legs?

Correction of "O-leg" and "splayed leg" O-leg is commonly known as bowleg, which is called genu varum in medicine and genu valgus in medicine, which is a common deformity in China. Especially teenagers, the incidence rate is higher. If young men and women get this kind of lower limb deformity, they will not only lose their physical beauty, but also walk badly. Sometimes, it will affect their participation in the army and work, thus affecting their love. Some of them will become depressed and even pessimistic. The main cause of deformity of "O" leg and "X" leg is rickets in children. A few are sequelae caused by cartilage development disorder, fracture, trauma and osteoma. When children suffer from rickets, due to the lack of calcium salt, the cartilage of epiphyseal hyperplasia can not be ossified normally, and the original bone is decalcified and absorbed, and the bone becomes soft and cannot tolerate gravity. In addition, the ligaments around the knee joint relax and lose the support and protection to the bones, so the calf bones bend and deform, and "O" and "X" legs appear. This kind of leg deformity not only affects body shape and bodybuilding, but also has a great impact on human health, and people often don't know enough about its harm. Knee varus or valgus destroys the normal stress distribution of the knee joint, which increases the biological stress on one side of the joint and decreases the biological stress on the opposite side. Over time, it will also cause knee pain when walking, and joint activity will also be affected, which will easily lead to osteoarthritis. Correcting this deformity can not only improve bodybuilding, but also improve the uneven stress distribution of knee joint. In recent years, external fixator combined with inverted U-shaped osteotomy of tibial tubercle has been applied to plastic treatment of "O" and "X" legs in China and achieved good results. The advantages of this new treatment mainly include: osteotomy is simple and safe, bone healing is fast, and it is not easy to delay healing. The use of external fixator is convenient to master the angle of plastic correction, which can make the angle of bone healing accurate and convenient to adjust; During the treatment, patients can move on the ground and the muscles of lower limbs will not atrophy. According to statistics, the complete correction rate of deformity can reach more than 96%. This new method also has the advantages of fast osteotomy healing and short course of treatment. Plastic surgeons may also increase their height after surgery, which can generally increase by about 2 cm after surgery, so they are welcomed by patients.
