Abstract

BACKGROUND
Traditional balloon kyphoplasty is comprised of a series of complex procedure, including entering a guide pin, placing a stylet and cannula over the guide pin, a hand-driven drilling to create a large channel, inserting a bone tamp and inflating the balloon to make the void. To find a convenient and manageable method for the restoration of compressed vertebrae, a new simple tool, the Sunflower Kyphoplasty, was designed using the restorative power of metal instead of an inflatable bone tamp. METHODS: To reduce the time-consuming complex procedures for making the void, and to reduce the pain during the creation of a large channel, we made a one step access portal with a 10-gauge cannula biopsy needle, which was much smaller than the 8-gauge cannula balloon traditional kyphoplasty working channel. To reduce the cost, we made a four-alae of stainless steel instead of an inflating balloon to make the void. Lastly, to evaluate the restoration, the average anterior, middle and posterior body heights of 10 patients before and after the treatment for fracture pain within 3 months and the volume of cement injected were measured. RESULTS: Using a unipedicular approach, the mean operation time was 22.5+/-5.6 minutes, the pain during the procedure was tolerable under local anesthesia with 30 mg of intravenous ketorolac, and height gains were 17+/-7, 15+/-5 and 14+/-3% of the predicted average anterior, middle and posterior heights. The mean volume of injected cement was 4.3+/-0.6 ml. CONCLUSIONS: Compared with traditional kyphoplasty, with a large working cannula and expensive balloon, a new method, the Sunflower Kyphoplasty, is less painful and time-consuming procedure during void construction. The volume of injected cement and height restoration were satisfactory.
