New Lordosis Study Findings Reported from Department of Neurosurgery (Early Compensatory Segmental Angle Changes At L3-l4 and L4-l5 After a L5-s1 Interbody Fusion for a Grade 1 Spondylolisthesis).

A new study conducted by the Department of Neurosurgery in Seattle, Washington, explores the effects of lumbar interbody fusion on compensatory changes in lordosis. The study focused on patients with grade 1 spondylolisthesis who underwent interbody fusion at the L5-S1 level. The results showed that a greater amount of lordosis achieved at L5-S1 was associated with a greater reduction of segmental lordosis at the adjacent L4-L5 and L3-L4 levels. Additionally, the study found that preoperative pelvic incidence played a role in influencing lordotic correction. This research provides valuable insights into the effects of interbody fusion on lordosis and can contribute to the development of treatment strategies for spondylolisthesis.
