FDA Clears Medtronic's Bone Cement to Treat Sacral Fractures

By Medtronic | March 15, 2017

Minimally invasive procedure provides more options for osteoporotic fracture patients suffering from pain.

Medtronic plc announced that the U.S. Food and Drug Administration (FDA) has granted 510(k) clearance of Kyphon Xpede Bone Cement for fixation of pathological fractures of the sacral vertebral body or ala using sacral vertebroplasty or sacroplasty—expanding the product's indications beyond treatment of vertebral fractures due to osteoporosis, cancer or benign lesions.
 
Sacral insufficiency fractures (SIFs) are a common cause of debilitating lower back pain in the elderly, with incidence ranging from 1 to 5 percent in at-risk populations.1,2 According to the National Osteoporosis Foundation, about 54 million Americans have osteoporosis and low bone mass, placing them at increased risk for a fracture. Breaking a bone is a serious complication of osteoporosis, especially with older patients. Osteoporotic bone breaks are most likely to occur in the hip, spine or wrist, but other bones can break, too—including the sacrum.3
 
"Sacral insufficiency fractures are associated with a tremendous amount of pain and debilitation for individuals who have them," said Dr. Douglas Beall, chief of Radiology Services at Clinical Radiology of Oklahoma. "Having this new indication with Kyphon Xpede Bone Cement to use in the treatment of sacral fractures will help to address this patient population."
 
A recent multi-center retrospective study of 243 patients with osteoporotic SIFs treated with sacroplasty reported significant pain relief for patients immediately following the procedure and after one-year follow-up; authors indicated that there were no major complications or procedure related deaths. The study reported a low procedure-related complication rate with 1 of 243 subjects (0.4 percent) having symptomatic leakage requiring decompression.2
 
"We are pleased to expand our therapies for interventional physicians treating osteoporotic patients to include those suffering from sacral insufficiency fractures," said Jeff Cambra, general manager of the Interventional Pain Therapies business, which is part of the Restorative Therapies Group at Medtronic. "As the pioneers in balloon kyphoplasty for treating vertebral compression fractures, this expanded indication for Kyphon Xpede Bone Cement demonstrates our long-term commitment to continuously innovate and empower physicians to deliver the best clinical solutions to their patients."
 
Kyphon Xpede Bone Cement is a quick-to-dough bone cement that provides ease of handling and allows sufficient time for careful, minimally invasive use. When paired with the Kyphon Cement Delivery System, clinicians can minimize their radiation exposure by standing up to four feet away from the radiation source during injection, which has been measured to reduce hand radiation exposure by 70 percent.4

Based on an internal testing of 24 total cadaveric procedures (n=12 using Kyphon CDS and n=12 using Kyphon(TM) Bone Filler Device). Dosimeters were placed on the wrist and fingers to measure radiation when delivering bone cement into the vertebral body. Radiation result reported is based on adherence to the Directions for Use.
