When Ms. Huang was 2 years old, she was found to have a deformed thoracic vertebrae. Some bones protruded. Due to family financial difficulties, and the children did not cry, they gradually forgot, and the result turned into a hunchback. Yesterday, the experts of the Institute of Digital Medicine of Nanjing First Hospital used 3D printing technology to make Ms. Huang, who had been humpback for 50 years, straight up the waist and grew 4 cm.
Congenital thoracic deformity, women's height fixation
Ms. Huang, 52, has been walking on her waist. A few days ago, she came to the Department of Orthopaedics, Nanjing First Hospital. I hope that the experts can help her cure the hunchback and let the body straight up and grow taller.
According to Ms. Huang, she had this problem every hour. When she was 2 years old, her family found a bone on her back. Because the family was poor and had many children at the time, they did not go to the hospital. Later, her back became more and more raised, and her height was always fixed at 150 cm.
After careful examination, Ms. Huang was diagnosed with congenital spinal deformity. Dr. Yao Qingqiang, Ph.D., Nanjing First Hospital, deputy director of the Institute of Digital Medicine of Nanjing Medical University and deputy director of the Key Laboratory of Digital Orthopaedics, told the reporter that there are 12 thoracic vertebrae in normal people, but her thoracic vertebrae in the 12th section showed developmental abnormalities. As a result, the formation of a hunchback, if left to develop, may lead to damage to the spinal cord, and even paralysis.
So, how can we let the body straighten up and grow taller? The first hospital expert thought of 3D printing technology.
3D printing "thoracic vertebrae", design surgery in advance
It is reported that due to the need to implant steel nails on the thoracic spine for reduction, the most important blood vessels and nerves of the human body can be densely distributed in the thoracic vertebrae. Once the steel nails are slightly deviated, it may damage the blood vessels and nerves, causing paralysis and death. . In order to ensure the safety of the operation, the first hospital doctor first input her thoracic CT and magnetic resonance raw data into a computer editing software linked with the 3D printer , and use the editing software to reset and restore her thoracic vertebrae. Subsequently, the doctor added powdered gypsum and adhesive to the 3D printer. After 10 hours, the “thoracic vertebrae†exactly the same as Ms. Huang was successfully printed.
Yao Qingqiang said that in the past, when the 3D printer technology was not used, the general thoracic deformity surgery had to open a mouth of about 10 cm, and after many attempts to implant the steel nail into the thoracic vertebra. The operation time is long, the wound is large, and the surgical path and accuracy are also prone to deviation. With 3D printing technology, the medical staff first locates the simulated thoracic vertebra exactly the same as Ms. Huang, and plans the personalized plan that is most suitable for the patient. After several simulated operations, the doctor then officially performs the operation for the patient. The normal condition is shortened by half, and the amount of intraoperative blood loss is small. Compared with traditional surgery, the operation has reduced risk, high precision, small damage and quick recovery. You don't have to wait for the surgery to find out, the nails are more accurate, so you can be foolproof.
3D printing human body parts in the next two or three years
Yao Qingqiang said that in addition to this routine surgery, the Institute of Orthopaedics currently implements 3D printing of bone, blood vessels, tumors and other tissues, but the application of 3D printing technology is still in its infancy, mainly to help patients design surgery in advance.
However, the First Hospital of Nanjing has gradually tried to develop a "prosthesis" printed by 3D printing technology, which is directly filled in the surgical defect, that is, the bones of the shape that can be done in the future can be, the patient can rely on this Technology achieves “private ordering†rather than using a line of products that are now standardized. It is expected that in the next two to three years, bone materials that can be placed into the human body in 3D printing will be developed. The 3D printer can print human organs and print out personalized "components" for patients.
