Posterior decompression and fixation is often proposed, but it is associated with a traumatic posterior approach, a large wound, and blood loss, a high risk of surgery site infections, and also instability of the metal fixation is possible. Also important is the increase in the surgical procedure cost due to the use of metal implants. An excellent alternative to standard posterior decompression and fixation is a method with isolated decompression of the cervical canal via posterior approach, which does not require any metal fixation.",[59,60,61],"Cervical Degenerative Disc Disease","Cervical Stenosis","Posterior Spine Surgery","2025-06-12",{"date":64,"type":38},"2025-06-17",{"date":66,"type":38},"2025-05-19",{"date":68,"type":20},"2026-08",{"name":44,"class":45},1,""]
