Human bones are part of the human body. Bones are composed of bone tissue, and living bone cells are part of the bone tissue.
Regardless of the fact that all orthopedic surgeons have heavy tools in their hands, like other surgeries, all treatments that orthopedic surgeons help patients also hope to use the body's own cells to repair damaged parts. This is the most natural, longest-lasting, and lowest side effect.
According to this idea, the best bone to fill the gap should be autologous bone. Autologous bone is obtained by taking part of the patient's own healthy bone or extracting bone material from a large bone. It is usually cancellous.
Just thinking about this bone removal surgical step, patients and their families can feel the tremendous pain that the patient has to endure. In the past, before breakthroughs in materials science were made, doctors and patients had no choice but to take this path. Therefore, autologous bone
Not the best way.
It is said that using the patient's own cells is the best, but what if autologous bone is not used? Don't make a mistake here. What doctors hope to use is the self-repair function of human cells, and whether or not autologous bone is used is not completely equal.
Through continuous research and progress in materials science, scientists and medical scientists have discovered that they only need to find materials that can be integrated with human cells for grafting, just like salt and water will eventually become one. There is no need to use other tissues of the patient's body to fill in the graft.
Gap. This is the forefront of contemporary medical research. When we go to various departments for medical treatment, the proper term we often hear doctors say is the biocompatibility of materials.
Gu JiaoIn addition to biocompatibility, bones have the characteristics of bones. Orthopedic surgeons must consider other professional factors when choosing materials for their specialty. For example, the material needs to function like human bone and be able to meet the mechanical conduction of the human body.
It has certain mechanical properties. The material must have a microporous structure that allows human cells to penetrate and grow. It is best to be absorbed and digested by human tissue like absorbable sutures. In this case, the material needs to be absorbed at a rate similar to that of bone cells.
Consistent. Finally, just like plaster, which allows doctors to shape it, human bones themselves have a three-dimensional shape.
The above requirements once again reflect that medicine is a science that integrates the most cutting-edge technologies of all sciences. Is there such a material? Yes, there is, but the best one has definitely not been found. If it could be found, human beings would have cracked the science of life long ago and could replace God's creation.
Human. Therefore, the application of human bone cannot completely replace all application scenarios of autologous bone.
Back to the current surgical patient. The patient is a teenager. The doctor will definitely not cut off a piece of the child's own healthy bone unless he has no choice. However, this spinal surgery removes a whole piece of the patient's bone, unlike other spine surgeries.
In bone defect surgery, artificial bone can be used to fill the missing part. To put it simply, if the entire bone is removed and there is too much bone, it is not suitable to fill it with artificial bone. If you want to reuse human cells, seeds cannot be sprinkled without soil.
For this purpose, the doctor adds artificial bone to the patient's autologous bone as a mixed filling, which is equivalent to using the artificial bone to make up for the insufficient amount of autologous bone to replace part of the role of the autologous bone for a certain period of time and wait for the growth of the autologous bone. The mixing ratio can be one to one.
What can be done with autogenous bone without cutting other bones? Doctors can use local materials. For example, spine surgery often uses decompressed bone to make mixed autogenous bone, and the broken ribs are crushed into pieces for waste utilization.
