When a person has a disease, it should be considered more serious if it reaches a point where surgery is required. Whether it is a fracture of a limb caused by trauma that requires internal fixation with incision, a herniated lumbar disc that compresses a nerve that requires disc removal, or a degenerative hyperplasia of the cervical spine that compresses a nerve and causes neck and shoulder pain and hand numbness and muscle atrophy that requires decompression and fixation and fusion, all of these diseases have a common feature, that is, there is an abnormality in a structure in the human body. The fracture, the original overall bone split into two or three pieces; lumbar disc herniation, the nucleus pulposus tissue break through the posterior longitudinal ligament into the spinal canal; cervical spondylosis, bone hyperplasia is too large to compress the nerve. There are other conditions, such as tumors in the intestines, hematomas in the skull, ventricular septal defects in congenital heart disease, and so on, all of which are structural abnormalities. Structural abnormalities are not simply functional disorders that can be treated by resting and taking some medication. To put it bluntly, it is to restore the original normal structure, which is our modern medical surgery. In the case of lumbar disc herniation, for example, the pathogenesis is not complicated: the protruding disc compresses the adjacent nerves and causes radiating pain in the lower limbs, and the weight-bearing capacity of the lumbar spine decreases after the disc is herniated, leading to back pain. The principle of treatment is to remove the herniated disc and release the nerve compression. So how can a herniated disc be removed? With a little anatomy, we can see that the herniated disc is in the central part of the spinal canal, in front of the dural sac that houses the nerves, and surrounded by either sensitive nerve tissue or a venous plexus that is prone to rupture and bleeding, so how can the herniated disc be safely and completely removed? How can humans do this without destroying other structures in the body? Doctors are not gods! Medical science is so advanced today that we can only first make a small opening in the patient’s skin, cut the subcutaneous tissue and fascia, peel away the muscle, open a small window between the laminae of the spinal canal, cut off part of the ligaments of the spinal canal, oh, into the spinal canal, but be more careful, but also the dural sac and nerve root sleeve (which is full of nerve tissue) with special tools to block away, finally see the protruding disc tissue, and then is carefully Then, the herniated disc was carefully separated and slowly removed. This process is very stressful and much more complicated than repairing appliances or cars! However, this is not the end of the process. The disc tissue remaining between the vertebrae is removed bit by bit, and the ruptured bleeding veins are coagulated with special instruments to stop the bleeding. Speaking of which, do you still care whether the incision on the skin is larger or smaller? Normal people will know that the size of the incision is not important, but the key is whether the problem inside is completely and thoroughly solved. Of course, the surgeon’s surgical level can influence the size of the incision here, and the more skilled the surgeon, the smaller the incision will be to solve the problem inside. However, neither the patient nor the surgeon should pursue the miniaturization of the wound so much that the key problems inside are not solved. You can’t lose the watermelon and pick up the sesame. In today’s increasingly advanced modern medicine, as physicians, we must not only get the inside right, but also address the surface skin issues. First, we try to reduce the incision as much as possible on the basis of ensuring that the key problems inside are completely solved; second, we try to choose the wound in a less conspicuous position; finally, we choose advanced intradermal suture, which not only does not have the traditional interrupted suture “centipede foot”, but also does not need to remove the suture. If the incision is not important, why do we need to go to so much trouble? I don’t know what other surgeons think, but I personally think that a perfect surgery is like a piece of fine art, and that perfectly healed wound is its label!
