Purpose

Vertebroplasty is considered nowadays one of the most powerful procedure in the treatment of vertebral compression fracture (VCF) in patients affected by osteoporosis, as well as patients with painful osteolytic vertebral lesions or selected trauma-induced fractures. One of the mail drawbacks is considered PMMA leakage related to excessive fluidity of the cement. Kummel disease or avascular osteonecrosys (AON) of the vertebra is an uncommon condition due to previous VCF with necrotic evolution of the fracture generally with severe cortical bone defects. We use a new kind of cement radiofrequency-sensible (RF Kyphoplasty - RFK) both to reduce the risk of extravertebral leakage and to restore the physiological hight of the vertebra without using osteotomic devices.

Methods & Materials

On a cohort of 1224 patients undergone to VP-KP procedure from 2003, 15 patients affected by AON were selected. The evaluation on heigh restoration and pain reduction according to a VAS scale were performed. After introducing a Jamshidi cannula inside the osteonecrotic area, RFK was performed.

Results

In all the patients but one the vertebra height after RFK increased significantly in comparison with pre-op scans (+35% m.v.). The pain related to the disease disappeared in 2 to 7 days after treatment. No extravertebral leakage of the RF sensible PMMA was appreciated on 2D CT scan after the treatment.

Conclusion

RF Kyphoplasty seems to be a new powerful technique in treating patients affected by AON.
