Balloon Kyphoplasty
The article discusses a case of an 84-year-old female who experienced complications during a vertebral body stenting system (VBS) procedure. The stents used in the procedure “toppled over” before the filling cement was fully applied, resulting in the need for an additional posterior fusion to maintain stability. The article highlights the importance of proper stent positioning and control of stent expansion during the VBS procedure. It also emphasizes the potential material-related complications associated with VBS that may be under-reported. The case serves as a reminder of the need for careful technique and monitoring during VBS procedures

The proper injection of cement into a VBS requires dual correct stent positioning, and careful control of requisite stent expansion. In an 84-year-old female with a T12 vertebral body fracture and a remarkable vacuum cleft, the VBS procedure resulted in an inadvertent injection into one stent thus warranting a secondary posterior fusion.

Abstract Background: Vertebral body stenting systems (VBSs) are superior to balloon kyphoplasty for performing vertebral augmentation and height restoration. However, VBS may likely result in more material-related complications that have been under-reported. Here, an 84-year-old female’s vertebral stents “toppled over” before the filling cement was fully applied, thus necessitating an additional posterior fusion. Case description:,

Case description: An 84-year-old female presented with low back pain after a fall. Dynamic standing and decubitus X-rays revealed a vertebral compression fracture at T12 resulting in an intravertebral vacuum cleft (i.e., the lowermost level of diffuse idiopathic skeletal hyperostosis). When the VBS was performed, the stents “toppled over” just after removing the balloon catheters; we successfully restored with the cement volume in one stent but not the other, thus warranting an additional posterior fusion to maintain stability.

In an 84-year-old female with a T12 vertebral body fracture and a remarkable vacuum cleft, the VBS procedure resulted in an inadvertent injection into one stent thus warranting a secondary posterior fusion.
