First, surgical correction.
This operation is suitable for patients with very serious O-leg or already complicated with osteoarthritis and joint pain. The advantage of surgery is passive treatment and immediate correction, without perseverance and persistence. The defect is that the surgical techniques are different, and most of them need osteotomy, which is painful, risky and expensive. 1. External fixator plus inverted U-shaped osteotomy of tibial tubercle. The advantages of this method mainly include: simple and safe osteotomy, fast bone healing, not easy to delay healing, easy to master the angle of plastic correction with external fixator, accurate bone healing angle and easy to adjust. Patients can move on the ground during the treatment, and the muscles of lower limbs will not atrophy. 2. Inverted U-shaped osteotomy of tibial tubercle and external fixation with tubular plaster after operation. According to statistics, the complete correction rate of O-leg deformity can reach more than 70%.
Second, non-surgical correction methods.
Manipulative correction is used to treat O-leg by correcting joint displacement. The principle of leggings and plus O meters is basically the same, which is to relax the medial collateral ligament of knee joint and restore the stable structure of medial and lateral knee joint. So as to make the tibia rotate outwards and achieve the purpose of correction. The advantages of non-surgical correction are low cost and low risk, while the disadvantages are active treatment, slow effect and long-term persistence. Without perseverance, it is impossible to achieve the goal of correction. 1, the principle of minimally invasive needle knife treatment is mainly to release the soft tissue of contracture disorder, because most O-legs are caused by soft tissue disorder, and the force line of lower limbs is abnormal, so the human body is a whole and must be adjusted as a whole. 2. Correction of the front splint and leggings This method is simple and easy, and the ligaments at the knee joint are adjusted by the pressure generated by the splint and binding. Its advantages are no need of operation and simple operation. The disadvantage is that you need to persist. Moreover, splint and binding are easy to damage the blood vessels and nerves in the knee joint, and even cause nerve necrosis in severe cases. 3. The instrument is also adjusted by adjusting the medial and lateral ligaments of the knee joint. The disadvantage is that active treatment is needed, and the length of correction cycle needs to be determined according to the patient's physique and perseverance, which is much higher than the cost of splint and binding. The advantage is that it can avoid damage to the blood vessels and nerves of the knee joint. 4. Orthopedic insole Orthopedic insole is high outside and low inside. When walking and standing, they can give the calf a force to rotate outward, which can prevent the aggravation and formation of O-shaped legs caused by poor walking posture. It is convenient to use, but it is effective for patients with mild O-leg, not suitable for patients with high O-leg. 5. The correction method of "O" leg through exercise is as follows: (1) Stand up straight, put your feet together, do squats with your knees in your hands, and stand in front of you for 20 ~ 3o times. (2) Bend down, and make circular movements with both hands and knees to the left and right for 20-30 times. (3) Keep your feet slightly open, bend over, and tuck your knees in your hands to stop your knees from leaning inward. Stop for 10 second each time and do it for 5 ~ 10 times. (4) Stand with two feet in parallel. First, take the heel as the axis and do toe abduction and internal rotation; Then do heel abduction and internal rotation 20 ~ 30 times with tiptoe as the axis. (5) Sit in a chair and try to hold the book with your calf for a while. If you tie your knees with rubber bands, the effect will be more obvious. (6) Sit on your knees, your waist collapses, your feet slowly move outward, and your waist will gradually straighten. Do 15 ~ 20 times. (7) Squat down, with hands akimbo, upper body upright, legs apart 15-20cm, toes slightly outward, and slowly squat down with knees together when inhaling, as deep as possible and pause for one minute, feeling the leg muscles tense. When exhaling, slowly open your knees, stand up straight and repeat 10 times. Knees and thighs are close together when squatting, which is very effective for correcting O-legs. The lower you squat, the better. It is very important to prevent O-legs from getting heavier. Except O-legs caused by congenital and organic diseases, most other O-legs are caused by acquired bad habits (kneeling, cross-legged, exercising, walking posture, etc.). ). Pay attention to these in daily life to avoid the formation of O-legs. Even patients who have been corrected by various methods should pay attention to various bad habits to avoid recurrence of leg types.
