Kyphon™ Balloon Kyphoplasty uses orthopaedic balloons to restore vertebral height and correct angular deformity from vertebral compression fractures (VCF) due to osteoporisis, cancer, or benign lesion. After reduction, the balloons are deflated and removed. The resulting cavity (void) allows for a controlled deposition of Kyphon bone cement — which helps form an internal cast and stabilize the fracture.
The Kyphon Balloon Kyphoplasty product is used to treat pathological fractures of the vertebral body due to osteoporosis, cancer, or benign lesions. Cancer includes multiple myeloma and metastatic lesions, including those arising from breast or lung cancer, or lymphoma. Benign lesions include hemangioma and giant cell tumor.
Components of the Kyphon Balloon Kyphoplasty system include:
Use of bilateral balloon kyphoplasty increases the lift force with less exerted stress on the in vitro model endplate vs. unilateral balloon kyphoplasty based on an engineering test environment that measured balloon lift force, balloon contact area and balloon exerted stress.
Results indicated that the unilateral and bilateral approaches to balloon kyphoplasty are statistically significant in all features assessed. The bilateral approach yielded a lift force that was 105% greater than the unilateral approach (102.66lbf v. 49.99lbf, respectively). The bilateral approach had a contact area that was 279% compared to the unilateral approach (1.34in2 v. 0.48in2, respectively). The exerted stress for the bilateral approach was 26% less than that of the unilateral approach (77.97psi v. 105.00psi, respectively).

The complication rate with Kyphon™ Balloon Kyphoplasty has been demonstrated to be low. There are risks associated with the procedure (e.g., cement extravasation), including serious complications, and through rare, some of which may be fatal.
