Clinical and radiological relationship between posterior lumbar interbody fusion and posterolateral lumbar fusion.

摘要: Abstract Background Posterolateral lumbar fusion (PLF) is the most popular technique for stabilizing spine. Biomechanically, PLF decreases segmental motion in posterior column, which presumably reduces facet joint pain. Posterior interbody (PLIF) may decompress nerve roots by distracting collapsed disc space, and achieving optimal relation to load-bearing capacity. The purpose of study was examine role fixation vs pedicle transverse assess treated adjacent space height changes over time. Methods One hundred patients who underwent PLIF noninstrumented process (n = 55) or instrumented 45) between 1996 1998 were evaluated retrospectively. Outpatient charts follow-up films reviewed. Bone determined using Brantigan Steffee's classification clinical outcome Prolo scale. Disc heights at levels measured. Analysis variance χ2 statistical techniques used data analysis. Results increased better maintained patients. resulted a nonsignificant tendency toward higher rates. No differences functional outcomes found groups. There no correlation preservation outcome. Conclusions does not seem impact fusion, efforts maintain it be unwarranted.
