1. Why is internal fixation often used during spinal surgery? The spine is connected by 26 vertebrae and is the main bone of the human body. It supports the body weight and also plays the function of protecting the nerves, blood vessels and internal organs. When fractures, dislocations, instability and damage from various causes occur in the spine, the only way to solve the problem is through surgery. The purpose of surgery is to relieve pressure on the nerves, stabilize and support the spine, and restore the normal anatomical relationship of the spine. Because the spine is a bony structure, it can only be supported and stabilized by rigid internal fixation. The current internal fixation used in spine surgery is usually titanium alloy material, which is very biocompatible and has very little effect on the human body. Therefore, the internal fixation material itself does not cause any adverse consequences to your health. 2.What are the precautions after spine surgery? (1) The anatomy of the spine is complex and the location is deep. Surgery on the spine is not a simple matter and requires certain equipment and technical conditions to perform this surgery. When you have a problem with your spine it is very painful, not only can you not work, but it affects your rest and can cause lifelong disability in serious cases. This is why it is important to have confidence and to overcome certain difficulties and to be prepared to fight against the disease. For example, the limitations of hospitalization, the inconvenience of life, the pain caused by surgery, etc.. You have to overcome all of them. As the saying goes: long pain is not better than short pain, as long as you overcome the difficulties, you can overcome all diseases and recover your health as soon as possible. (2) In terms of diet: within 7 days after surgery, the main focus should be on flowing juice, with many meals and few meals (such as chicken soup, fish soup, egg soup, juice, milk, etc.). This not only ensures the supply of sugary nutrients, but also reduces the number of bowel movements and the burden of nursing care. (3) In terms of functional rehabilitation: The spine is the main bone of the human body, which has the function of support, protection and movement. It takes a certain amount of time to fully recover after surgery. For example; it takes about 3 weeks for the repair of soft tissues and 3-6 months for the surgical repair of bony structures. How does rehabilitation take place during this time? Do more straight leg raising exercises for the lower extremities and exercises for the upper extremities in bed for 10 days after surgery. In the 15 days after the surgery, you can continue to strengthen the upper and lower limb exercises, and gradually resume sitting and standing activities. Three weeks after surgery, you can go down to the ground with the protection of a brace. Avoid weight-bearing for 3 months. Regularly come to the hospital for review 1-3 months after discharge. 3.What cases should be removed after spinal internal fixation surgery? (1) For anterior cervical, anterior thoracolumbar and posterior upper cervical surgery, the internal fixation should not be removed under normal circumstances. If the internal fixation is loosened or broken, it is better to remove it. (2) The internal fixation of posterior thoracolumbar spine surgery can be taken out around the postoperative period. If you do not come to the hospital to take out the internal fixation in time, you need to come to the hospital for review in 2-3 months regularly. If there is loosening or fracture, you should come to the hospital to take it out in time. (3) after the spinal internal fixation surgery, stay in the body for a long time, subject to numerous extrusion of the body’s center of gravity and muscle contraction, if the patient also has osteoporosis, the internal fixation is easy to fatigue loosening or fracture. Just like a strong stool bought from the mall, it will loosen and break after frequent use. Once the internal fixation is loose or broken, there is no need to worry too much. Please visit a spinal surgery specialist for a review, and the doctor will take care of the situation accordingly.
