Object. Osteoporotic vertebral fractures occasionally lead to late-onset collapse, kyphosis, persistent back pain, and disability. The authors describe a series of patients in whom they performed percutaneous vertebroplasty by using calcium phosphate cement (CPC) to obtain early pain relief and improve the integrity of the osteoporotic vertebral body (VB).

Methods. Between August 2000 and February 2001, they performed 17 percutaneous transpedicular CPC-assisted vertebroplasty procedures in 16 patients who harbored thoracic or lumbar osteoporotic vertebral fractures. Following repositioning and curettage of the pathological soft tissues, CPC-assisted vertebroplasty was percutaneously performed in four patients with osteoporotic burst fracture and pseudarthrosis (Procedure A). In situ CPC-assisted vertebroplasty was performed in 12 patients with fresh vertebral …
