Anterior vs. posterior approaches in the management of multilevel degenerative cervical myelopathy: a systematic review and meta-analysis Open
Both surgical approaches yield comparable long-term outcomes, with anterior surgery demonstrating statistically significant early functional advantages, shorter LOS, and lower odds of C5 palsy. However, these advantages diminish over time,…
