Traditional bone filling materials are easy to be accompanied by complications, but new inventions can avoid this risk.
He Jincang, deputy director of the South Branch, explained that after 20 years of hard work behind this invention, exciting results have finally been achieved. The strength of scientific researchers in Taiwan Province can definitely be on an equal footing with other countries in the world. Dr. Li Jingwei, director of surgery at Chengda Hospital, pointed out that the traditional bone filler is taken from another bone of the patient, which will definitely cause additional scars and possible complications and prolong the operation time. The newly invented biomedical materials can avoid the above risks, which is the biggest bright spot. In addition, it also has the advantages of rapidity, effectiveness and conformity with physiological conditions, which is helpful for clinicians to operate and restore patients' health smoothly.
Traditional bone cement is made of biological bone materials or synthetic polymers, which can infect, spread diseases and inflammatory reactions in vivo, but newly developed materials have been able to overcome these problems. Dr. Li Jingwei also said that this product is purely a combination of minerals, its components are calcium and phosphorus, and it does not contain organic substances in traditional medical materials, which can avoid rejection and reduce the risk of infection.
There have been many successful clinical cases of using "calcium-based" materials to reduce inflammation.
This invention has a living success story for reference. A 22-year-old man had a sunken forehead due to a car accident. The patient didn't want to have a complicated operation, so he chose to stick the bone mud with a needle. After 3 years of follow-up, the effect is good. 1 A 75-year-old uremia patient, suffering from severe diabetes and long-term renal dialysis, underwent coronary artery bypass grafting due to myocardial infarction complicated with heart failure. The operation went smoothly and the heart function recovered well. However, due to poor sternum healing, it is impossible to breathe spontaneously, and even it has cracked, so it is necessary to suture the sternum again. Adding "Sugu Granule" during operation? In order to promote bone regeneration, the patient recovered after the second operation 14 days, and the sternum healed well.
Chen Jinhui, a professor of materials department at Chengda University, said that the bone paste and bone granules used in orthopedics and dental implants are mainly made of artificial materials "calcium-based", which are characterized by not causing foreign bodies or inflammatory reactions and can be used immediately in acute stage. Among them, Sugu granules have high absorption rate and can be completely replaced by new bone several months after implantation, achieving the effect of rapid healing. Su bone mud will not disintegrate when it comes into contact with blood and body fluids, thus avoiding fatal problems such as vascular embolism caused by bone mud, but traditional bone mud cannot rule out this risk.
The material of Su Gu Mud will be combined with new bone, and the postoperative effect of patients is good.
Professor Zhu Jianping from the Department of Materials explained that the reason why Sougou mud won't disintegrate is that the team can skillfully control the growth mechanism of calcium-based nano-whiskers in Sougou mud at different speeds in different environments (such as pH, hardener concentration, etc.). These two artificial bone materials will be closely combined with new bone after implantation, and there will be no fibrous tissue on the interface, which has high bone induction, and then 100% will be replaced or replaced by healthy new bone.
Many patients with bone diseases in plastic surgery, orthopedics, cardiac surgery and dentistry in Chengda Hospital have been treated with this new artificial bone material. Some people have achieved good results after three years of follow-up, and they have also proved excellent performance in clinical application. This newly developed medical material is expected to benefit more patients in the future.
