Kyphon Balloon Kyphoplasty
 

Indications, Safety, and Warnings

Kyphon Balloon Kyphoplasty

The complication rate with Kyphon® Balloon Kyphoplasty has been demonstrated to be low (< 1% procedure- and cement-related1). As with all surgical procedures, there are risks associated with the procedure, including serious complications, and though rare, some of which can be fatal. For complete information regarding indications for use, contraindications, warnings, precautions, adverse events, and methods of use, please reference the devices’ Instructions for Use included with the product.

Adverse events potentially associated with use of the Inflatable Bone Tamps (IBT)

  • Embolism of fat, thrombus or other materials resulting in symptomatic pulmonary embolism or other clinical sequelae.
  • Rupture with fragmentation of the inflatable portion of the IBT resulting in retention of a fragment within the vertebral body.
  • Rupture of the IBT causing contrast medium exposure, possibly resulting in an allergic reaction or anaphylaxis.
  • Deep or superficial wound infection.
  • Retropulsed vertebral body bone fragments which may cause injury to the spinal cord or nerve roots resulting in radiculopathy, paresis or paralysis.
  • Bleeding or hematoma

Serious adverse events, some with fatal outcome, associated with the use of acrylic bone cements (Kyphon® HV-R® Bone Cement)

  • Cardiac arrest
  • Cerebrovascular accident
  • Myocardial infarction
  • Pulmonary embolism

Other reported adverse events relevant to the anatomy being treated with acrylic bone cements include:

  • Deep or superficial wound infection
  • Fistula
  • Hematoma
  • Hemorrhage
  • Heterotopic new bone formation
  • Extravasation of bone cement potentially resulting in but not limited to:
  • Compression or irritation of nerve structures, such as the spinal cord or nerve roots, causing radiculopathy, parasthesia, paraplegia or paralysis and/or;
  • Introduction into the vascular system resulting in embolism of the lung and/or heart or other clinical sequelae
  • Pyrexia due to allergy to bone cement
  • Short-term conduction irregularities
  • Thrombophlebitis
  • Transitory fall in blood pressure

Inflatable Bone Tamps (IBT) – Indications for Use
Kyphon® Xpander™ and Kyphon® Express™ Inflatable Bone Tamps (IBT) are intended to be used as conventional bone tamps for the reduction of fractures and/or creation of a void in cancellous bone in the spine (including use during balloon kyphoplasty with Kyphon® HV-R® Bone Cement), hand, tibia, radius, and calcaneus.

Kyphon® HV-R® Bone Cement – Indications for Use
The Kyphon® HV-R® Bone Cement is indicated for the treatment of pathological fractures of the vertebral body due to osteoporosis, cancer, or benign lesions using a balloon kyphoplasty procedure. 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.
