Summary
BACKGROUND: Posterior lumbar interbody fusion (PLIF) has turn into a basic surgical technique for degenerative lumbar ailments. Though many reviews have targeted on single-level PLIF, few have targeted on 2-level PLIF, and no report has coated the fusion standing of 2-level PLIF. The aim of this examine is to research medical outcomes and fusion for 2-level PLIF through the use of a mix of dynamic radiographs and multiplanar-reconstruction computed tomography scans.
METHODS: This examine consists of 48 consecutive sufferers who underwent 2-level PLIF for degenerative lumbar ailments. We assessed surgical procedure length, estimated blood loss, issues, medical outcomes as measured by the Japanese Orthopaedic Affiliation (JOA) rating, lumbar sagittal alignment as measured on standing lateral radiographs, and fusion standing as measured by dynamic radiographs and multiplanar-reconstruction computed tomography. Sufferers have been examined at a follow-up level of four.eight±2.2 years after surgical procedure. Thirty-eight sufferers who didn’t bear lumbosacral fusion comprised the LL group, and 10 sufferers who underwent lumbosacral fusion comprised the LS group.
RESULTS: The imply JOA rating improved from 12.1 to 22.1 factors by the ultimate comply with up examination. Sagittal alignment was additionally improved. All sufferers had fusion within the cranial stage. Seven sufferers had nonunion within the caudal stage, and the LS group (40%) had a considerably poorer fusion price than the LL group (97%) did.
CONCLUSIONS: Surgical outcomes of 2-level PLIF have been passable. The fusion price at each ranges was 85%. All nonunion was noticed on the caudal stage and concentrated at L5-S stage in L4-5-S PLIF.
