The retrospective analysis of the effect of balloon kyphoplasty to the adjacent-segment fracture in 171 patients.
Analysis of the adjacent-segment fractures in 171 balloon kyphoplasty (BK)-performed patients. ⋯ If the patients experience severe or mild back pain with higher preoperative KA, especially in the first 2 months, then they deserve detailed radiologic examination. To avoid subsequent fracture in the same or adjacent level, vertebral body should be filled adequately and sagittal balance should be obtained with KA correction. BK alone did not influence the incidence of subsequent VCF.

Does lumbar disk degeneration increase segmental mobility in vivo? Segmental motion analysis of the whole lumbar spine using kinetic MRI.
This is a retrospective analysis of lumbar segmental motion using Kinetic magnetic resonance imaging(KMRI). ⋯ In functional positions assessed utilizing weight bearing KMRI, segmental motion at levels with degenerated disks was decreased. The contribution of upper lumbar segments to the total lumbar motion was not smaller than that of the lower segments. The L5–S1 level showed the smallest ROM in lumbar motion.

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.

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.

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.
