Abstract
Our aim was to describe the immediate or early complications and technical failures occurring during balloon kyphoplasty (BKP) procedures and attributable to balloon inflation. We performed a retrospective review of all consecutive kyphoplasty procedures performed in our institution from May 2005 to October 2006. Fifty-one patients were treated by BKP at 75 spinal levels, and 137 vertebroplasties were performed as well. Several recurrent complications or procedural failures were observed during BKP: cortical or endplate fracture by balloon expansion (4 vertebrae), partial vertebral re-collapse after deflation (4 vertebrae), balloon rupture during inflation (5 vertebrae), and transient hyperalgia after the procedure (11 patients, 27.5%). Several symptomatic or asymptomatic complications and technical failures can occur during BKP. Some modifications of the usual kyphoplasty technique may decrease the frequency of these complications.

AND PURPOSE: Our aim was to describe the immediate or early complications and technical failures occurring during balloon kyphoplasty (BKP) procedures and attributable to balloon inflation
Percutaneous balloon kyphoplasty (BKP)1 is an interventional radiologic technique that has been used in the treatment of vertebral compression fractures due to various causes such as osteoporosis, metastases, or trauma
In BKP, inflated balloon tamps are used to restore the height of the vertebral body and correct kyphosis before injecting bone cement for stabilization of the fracture
Summary
Our aim was to describe the immediate or early complications and technical failures occurring during balloon kyphoplasty (BKP) procedures and attributable to balloon inflation. The purpose of this article was to review the possible technical failures and complications in BKP that are related to balloon expansion inside the vertebral body and to discuss possible modifications of the usual kyphoplasty technique that can be applied to decrease the incidence of these events
