Should percutaneous vertebroplasty be used to treat osteoporotic fractures? An update.

Acrylic cement vertebroplasty is being increasingly used to treat osteoporotic vertebral compression fractures (VCFs), although no controlled studies supporting this trend have been published. Vertebroplasty remains controversial as a treatment for osteoporotic fractures because it is a local response to a systemic disease and because the pain caused by osteoporotic fractures usually subsides within a few days or weeks. Current data suggest that pain severity may decrease by half, on average, in 90-100% of patients. Although vertebroplasty is usually well tolerated, serious neurological complications have been reported in a few patients. The most common adverse event is nerve root pain, usually caused by leakage of the cement into the intervertebral foramen. Whether vertebroplasty is followed by an increased risk of osteoporotic fractures in the adjacent vertebras remains unclear. Resorbable cements are being developed and may provide better results than the acrylic cements used today. At present, acrylic cement vertebroplasty to treat osteoporotic VCFs is appropriate in only a minority of patients selected carefully by a multidisciplinary team including a rheumatologist.
