Severe kyphotic deformity resulting from collapses of cemented and adjacent vertebrae following percutaneous vertebroplasty using calcium phosphate cement. A case report.

Percutaneous vertebroplasty (PVP) has been increasingly performed for the treatment of osteoporotic vertebral compression fracture. Despite its minimally invasive procedure, several complications associated with PVP have been reported, including adjacent-level vertebral fracture. Although rare, recollapse of the same vertebrae after PVP has also been reported. However, previous studies have not described a case in which collapses of both the cemented vertebrae and adjacent-level vertebrae occurred following PVP. Here, we report a rare case of severe kyphotic deformity resulting from collapses at the cemented and adjacent vertebrae after PVP using calcium phosphate cement (CPC). The patient required a highly invasive reconstruction procedure as a salvage surgery.
