Risk factors for adjacent segment disease after posterior lumbar interbody fusion and efficacy of simultaneous decompression surgery for symptomatic adjacent segment disease.
A retrospective study. ⋯ Patients whose facet joint at the adjacent segment had a more sagittal orientation had postoperative anterior listhesis, which caused symptomatic ASD. Simultaneous decompression surgery without fusion at the adjacent level was not effective for these patients, but rather, there was a possibility that it induced symptomatic ASD.

Minimally invasive transforaminal interbody fusion surgery for the old fracture of the thoracolumbar junction.
Retrospective analysis of the clinical outcomes of 15 patients with the old thoracolumbar junction fracture treated by minimally invasive surgery (MIS) transforaminal interbody fusion surgery. ⋯ MIS transforaminal interbody fusion is a safe and effective procedure for old thoracolumbar junction fracture with chronic pain. Improvement of kyphosis is limited and occurrence of nonunion is relatively high.

Usefulness of an early MRI-based classification system for predicting vertebral collapse and pseudoarthrosis after osteoporotic vertebral fractures.
Retrospective review. ⋯ Our results suggest that the radiologic prognosis can be estimated to a limited extent by determining the degree and extent of osteoporotic vertebral fractures using an early magnetic resonance imaging-based classification.

A novel minimally invasive technique for the treatment of high-grade isthmic spondylolisthesis using a posterior transsacral rod.
Case report of 3 patients with high-grade isthmic spondylolisthesis treated using a novel minimally invasive technique using a posterior transsacral rod. ⋯ We have shown the technical feasibility of anterior and posterior fusion for severe L5-S1 spondylolisthesis using a minimally invasive percutaneous technique through a transsacral approach. The main advantage of a posterior transsacral axial rod fixation is that it creates a structurally sound anterior column support, thus eliminating the problems related to bone grafts and eliminating the complications associated with an anterior approach. Our preliminary results suggest that this technique is feasible and seems to be associated with favorable outcome, although larger studies are warranted to verify these findings.
