    Human bones are part of the human body. Bones are composed of bone tissue. Living bone cells are part of the bone tissue.

    ?????????????????????????????????????????????????????????????????????????????????????????????????????????????

    According to this idea, the bone block to fill the gap should preferably be autogenous bone.  Autologous bone is obtained by removing part of the patient's own healthy bone or extracting bone material from a large bone, which is usually cancellous.

    Just thinking about this bone removal surgical procedure, the patient and his family can feel the tremendous pain that the patient needs to endure.  Before breakthroughs in materials science were made in the past, doctors and patients had no choice but to take this path without suffering any more pain.  Therefore, autologous bone is not the best way.

    It is said that it is best to use the patient¡¯s own cells, but what if autologous bone is not used.  Make no 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 equated.

    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. The term we often hear doctors say when we go to various departments for medical treatment is the biocompatibility of materials.

    In addition to biocompatibility, bones have the characteristics of bones, and orthopedic surgeons must consider other specialty factors when choosing their own specialty materials.  For example, this material needs to function like human bone, be able to meet the mechanical conduction of the human body, and have 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 tissues like absorbable sutures. In this case, the material needs to be absorbed at about the same rate as bone cells grow.  Finally, just like plaster, which allows doctors to shape the shape, the human bone itself has a three-dimensional shape.

    The above requirements once again reflect that medicine is a science that combines the most cutting-edge technologies of all sciences.  Is there such material?  Yes, there are, but I definitely haven¡¯t found the best one.  If it could be found, humans would have cracked the science of life long ago and could replace God in creating humans.  Therefore, the application of human bone cannot completely replace all autologous bone application scenarios.

    Back to the current surgical patient.  The patient is a teenager, and the doctor will definitely not cut off a piece of the child's own healthy bone unless he has no other choice.  Unfortunately, this spine surgery removes a whole piece of the patient's bone, unlike other bone defect surgeries where artificial bone can be used to fill the missing area.  To put it simply, after removing the whole bone, there are too many missing bones and it is not suitable to fill it with artificial bone. If you want to reuse human cells, you cannot sprinkle seeds into it 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 artificial bone to make up for the insufficient amount of autologous bone, replacing part of the role of autologous bone for a certain period of time, and waiting for the autologous bone to grow.  The mixing ratio can be one to one.

    What can you do with autogenous bone without cutting other bones?  Doctors can source materials locally.  For example, spinal surgery often uses decompressed bone to make mixed autologous bone, and the broken rib is crushed into pieces and used as waste.  (Remember the website address: www.hlnovel.com
