Preliminary study on a single balloon cross-midline expansion via unipedicular approach in kyphoplasty.

Background: Recently, bilateral transpedicular kyphoplasty with a single balloon was performed for osteoporotic vertebral body compression fractures (OVCFs) to reduce the fees of the operation, but the time of operation and radiation exposure are longer. The aim of this study was to determine the safety and effectiveness of a single balloon cross-midline expansion via unipedicular approach in kyphoplasty for OVCFs.

Methods: Thirty-six patients with painful OVCFs (61 vertebrae) were enrolled in this research.

[Percutaneous kyphoplasty with double or single balloon in treatment of osteoporotic vertebral body compressive fracture: a clinical controlled study].

Objective: To evaluate the clinical efficacy of percutaneous bipediculary kyphoplasty with double or single balloon I treatment of osteoporosis vertebral compressive fractures.

Methods: Fifty-one patients with painful osteoporotic vertebral compressive fracture involving 69 vertebrae. 19 males and 32 females, aged 72.
