Percutaneous transpedicular intracorporeal cage grafting for Kümmell disease.

Abstract

Osteonecrosis with progressive collapse and segmental kyphosis can lead to intersegmental instability in some osteoporotic vertebral compression fractures (OVCFs). These conditions are known as Kümmell's disease and often require anterior column reconstruction in elderly patients. We attempted anterior column reconstruction by percutaneous transpedicular intracorporeal cage grafting (PTICG) with short-segment pedicle screw fixation and described the steps, with discussions on the surgical indications and pros and cons. PTICG is expected to be an alternative to vertebral anterior column reconstruction, which can preserve the thoracolumbar posterior arch and paravertebral musculature.
