Purpose: Several risk factors for adjacent segment disease (ASD) after posterior lumbar interbody fusion (PLIF) have been reported. High pelvic incidence (PI) has been identified as risk factors for L4 anterior slip in cases of lumbar degenerative spondylolisthesis. Correcting the slip with L4-L5 fixation merely restores the lumbar alignment, but the PI itself remains unchanged.

The purpose of this study was to compare the efficacy of HU and DXA T-scores in predicting adjacent vertebral fractures (AVF) following balloon kyphoplasty (BKP) using the same computed tomography and DXA at one institution.
Methods: The study included 84 cases (20 males, 64 females, mean age 79.
Article Synopsis
- The study investigated whether prior adjacent vertebral fractures (AVF) influence the development of new AVFs after balloon kyphoplasty (BKP) in patients with a history of fractures.
- Data from 133 patients undergoing BKP revealed no significant difference in AVF occurrence between those with previous fractures (Group P) and those without (Group C), although Group P had lower bone quality and more prior fractures.
- Within Group P, previously fractured vertebrae had a significantly lower incidence of new AVFs compared to contralateral non-fractured vertebrae, indicating a potential protective effect of prior fractures against further AVFs.
Background: Prevention of adjacent vertebral body fracture (AVF) following balloon kyphoplasty (BKP) is a key challenge. The objective of this study was to develop a scoring system that could be more extensively and effectively used to determine the surgical indications for BKP.
Methods: The study involved 101 patients aged 60 years or older who had undergone BKP.
Background: Recently, it is widely known that global sagittal balance (GSB) influences the postoperative outcome of the spine. The purpose of this study was to investigate the relationship between GSB and the incidence of early adjacent vertebral fracture (AVF) following balloon kyphoplasty (BKP).
Methods: This study included 96 patients (19 males, 77 females, mean age 77.
