EFFICACY OF PERCUTANEOUS BALLOON KYPHOPLASTY AS A DIAGNOSTIC TOOL IN VERTEBRAL COMPRESSION FRACTURES

British Association of Spinal Surgeons (BASS)



Abstract

Purpose

To elucidate the efficacy of carrying out additional vertebral biopsy procedure during percutaneous balloon kyphoplasty as a tool in determining malignant etiology.

Methods and Results

We performed 138 percutaneous balloon kyphoplasty procedures in 85 patients during august 2007 to march 2010. Gender distribution was 25 males and 60 females. Age distribution was 33 to 85 years, with an average age of 67.4 years.

The senior surgeon attempted vertebral biopsy during percutaneous balloon kyphoplasty procedure only when there was a clinical/operative suspicion of malignancy. We did not routinely biopsy all vertebrae, as this would mean additional procedure adding to the cost and operating time.

In 42 procedures vertebral biopsy was attempted, of which 5 samples were reported as insufficient specimen. 37 biopsies (88%) were successfully analyzed. 3 biopsies (8.1%) were positive for malignancy. There were no complications encountered in the cases where additional biopsy procedure was carried out.

Conclusion

There is not much literature supporting routine use and efficacy of biopsies during percutaneous balloon kyphoplasty procedures.

Although the quality of bone could make vertebral biopsy challenging in all cases, we feel that improved technique of taking biopsies and maybe increasingly performing the additional biopsy procedure could detect more positive malignancies.

Routine biopsies during percutaneous balloon kyphoplasty may be invaluable in diagnosing malignancies.
