When Zhang was 3 years old, he had a slight thoracic depression, and the attentive mother of Zhang soon found out. But she thought that calcium deficiency caused by the calcium supplement will do. In the following years, his mother gave him calcium every day, but the depression not only did not get better, but also heavier than when he was a child, and so on until Zhang was in the third grade. A few months ago, the family wanted to buy a new dress for him, but to the store the child said nothing to take off clothes to try on, and also with his father had a fight. The school organized a trip to the beach to play, Xiao Zhang simply do not want to swim, back has been sullen. The physician found that Zhang’s chest is concave, like a bowl, is typical of the “funnel chest”. Funnel chest is a chest wall deformity. The human chest bone is divided into ribs and rib cartilage. The cartilage is underneath the hard rib cage. If the rib cartilage grows too fast and exceeds the length of the rib cage, it can only grow inward or outward, and if it grows inward, it will be sunken in, forming a “funnel chest”. Is there a calcium deficiency in the “sunken chest”? ”The ratio between men and women is 4 to 1. That is to say, if someone in your immediate family has a “funnel chest”, your offspring will have a higher chance of getting the disease, so pay attention to it. In some cases, no one in the patient’s family has the disease, but they have the gene that causes the disease. In fact, “funnel chest” is so obvious that parents can see the difference as soon as the baby is born and can feel it more clearly by touching it. However, parents or inexperienced physicians often treat this phenomenon as a calcium deficiency, “which is one of the most common misconceptions among patients. Because of this, many patients delay treatment. In fact, calcium supplementation cannot cure or prevent funnel chest. Calcium deficiency does affect bone development, but the bone problem caused by calcium deficiency is clinically known as “beaded chest”, the sternum looks particularly irregular to the naked eye, while “funnel chest” is much more regular. In addition, there are other symptoms of calcium deficiency, such as excessive sweating, easily startled, tiredness, sleep disturbance, etc. In addition to misdiagnosis caused by wrong diagnosis, the patient’s low self-esteem also makes the disease repeatedly delayed diagnosis and treatment. Some parents did not find the problem when they were young, while patients with the problem have low self-esteem and often have to dress up tightly for fear of being ridiculed. They do not dare to swim in the water because they are afraid to wear a close-fitting swimsuit. Even on hot days, they do not dare to wear thin clothes, so even their parents do not know about it, and they keep delaying treatment. Surgery around the age of 10 is the best time Surgical treatment is the only effective means. If the symptoms are mild, you can observe first to see if it has developed more seriously. If it has affected the aesthetics, then surgery can be done to solve it. In contrast, surgical solution is advocated for moderate and severe patients. This is because, in severe cases, thoracic inversion can lead to special body shapes such as scoliosis, hunchback, and abdominal protrusion. Even symptoms such as panic and shortness of breath after activity, recurrent respiratory infections, anterior heart area pain and palpitations occur. The best time for surgery is from 6 to 15 years old, with the best around 10 years old. At this time, the development of the thorax has been basically formed, too young for fear of affecting the development, and older, the bones have grown hard, if the operation is more painful for the patient himself, the operation is also more difficult. The surgery is performed by making two small openings at hidden locations on both sides of the thorax and using a thoracoscope, the plasticized steel plate is placed into the thorax to lift the sternum, and the deformity is corrected, and the plate is removed 2 to 3 years later when the thorax is plasticized and stable.
