Is cervical spine surgery done from the front or from the back? I will answer this question briefly: Indications for anterior surgery: compression from the spinal nerve in front of the disc, bone spur compression, relatively limited, not many segments (not more than three discs range) Advantages: 1, less bleeding, less trauma, fast recovery 2, can restore or maintain the normal physiological curvature of the cervical spine Disadvantages: for multi-segment, severe spinal cord compression is not applicable. Indications for posterior surgery: Applicable to multi-segmental cervical spondylosis (more than three discs) with cervical stenosis or continuous posterior longitudinal ligament ossification. Advantages: Indirect decompression is achieved by decompression and reconstruction of the posterior cervical lamina. It is less risky than the anterior approach and is more effective. Limitations: Not suitable for patients with cervical kyphosis. To summarize, the key to cervical spine surgery from the anterior or posterior approach is the direction of compression of the spinal cord and the number of compressed segments, as well as the physiological curvature of the cervical spine to make a suitable choice for the patient.
