Advances in Vertebral Augmentation Systems for Osteoporotic Vertebral Compression Fractures

Figure 5

A percutaneous nitinol coil guidewire (a) is coiled within the cancellous portion of the fractured vertebral body. (b) Afterwards, a radiopaque PEEK implant is delivered incrementally via the nitinol coil guidewire (c) and then a nesting, cylindrical column is formed that provides vertical displacement, which may restore the height of the fractured vertebra (d) [10]. Fluoroscopic images illustrating the procedure of using the Kiva VCF treatment system (e). After removing the coil, a radiopaque PEEK implant was implanted (f) to provide structural support to the vertebral body and then bone cement was injected through the implant, as shown by lateral (g) and anteroposterior (h) fluoroscopic images [10].
