Balloon kyphoplasty (BKP) is an innovative interventional procedure for treating VCFs. Performed with the patient under
conscious sedation (awake but sedated), a small skin incision is made and a cannula is inserted through a pedicle into the
the vertebral body under fluoroscopic guidance. A manual drill creates space for a balloon to be inserted into the vertebral body, with two radio-opaque marker bands indicating the balloon location within the vertebra. The balloon is inflated with radio-opaque contrast liquid under fluoroscopic visualization to monitor the inflation pattern within the vertebra. The omnidirectional balloon expansion lifts the endplates and restores the anatomical shape of the vertebra. The balloon is then deflated and removed, leaving behind a void. This void is filled with bone cement, which acts as an internal cast to stabilize the fracture.
Access to the fractured vertebral body is made with small diameter stainless steel tools (i.e., a solid rod stylet and a
cannulated working channel). A cannula is placed through each pedicle for bilateral access. Inflatable bone tamps (IBTs) are placed through the cannulas and inflated to reduce the fracture. Once the desired reduction is achieved, the IBTs are deflated and removed, leaving behind a void. The resulting void is filled with bone cement, which acts as an internal cast to stabilize the fracture. BKP is typically performed on an outpatient basis, and patients can go home.
