Introduction: Radiofrequency (RF)-Kyphoplasty is a new development in vertebral
augmentation procedures with an innovative cement application system. The aim of
this prospective study was to evaluate the efficacy of this novel technique. First
clinical results in the treatment of osteoporotic vertebral fractures are
presented.Materials and Methods: Twenty-eight patients (19 women, 9 men, average
age 70.8 years) with thirty-nine symptomatic osteoporotic vertebral fractures located
in the thoracic and lumbar spine were treated between May 2009 and January 2010.
Fractures were diagnosed on standard radiographs, whereas the symptomatic level
was identified by MRI. Reduction of pain was evaluated using the visual analogue
scale (VAS). For clinical assessment the Oswestry Disability Index (ODI) score was
documented before and after surgery. Leakage of cement was assessed on standard
plain radiographs and classified into type B (basisvertebral vein), type S (segmental
vein), and type C (cortical defect). Results: All the patients studied experienced an
early and persistent pain relief (VAS) after treatment and improved significantly in the
quality of daily life (ODI). Although there were no technical problems in the
performance, cement leakage occurred in 13 of 39 (33%) augmented vertebrae,
whereas extravasation through cortical defects (type C) was the most common (85%)
complication. Non of the patients suffered from a constriction of the spinal channel or
any other life-threatening complications. Conclusion: RF-Kyphoplasty represents an
efficient alternative treatment option for symptomatic osteoporotic vertebral fractures
and may offer new therapeutic options in the treatment of pathological vertebral
fractures following RF tumor ablation.
