When Tom Callaghan had a hole-in-one on the fourth hole of his favorite golf course in 1998, he didn't expect to be carried off the course less than an hour later after collapsing in agony on the ninth tee. A tumor had disintegrated a vertebra in the middle of his back, compressing his spinal cord and causing unbearable back pain. Then 51 and practicing law, Callaghan was diagnosed with multiple myeloma, a cancer of bone, and given just two years to live.

Callaghan is one of an estimated 100,000 Americans suffering from multiple myeloma. The International Myeloma Foundation estimates that as many as half of these patients will experience fractures of the spine causing debilitating back pain and substantially reducing quality of life.

"I couldn't stand up straight," Callaghan said. "The pain was constant. I couldn't stand for more than a couple minutes without severe pain. And I couldn't play golf, which is my passion."

Callaghan learned about a treatment option, Balloon Kyphoplasty, to address his vertebral compression fractures and underwent the procedure three times: once in May 2001 and twice in August 2001.

"My pain was relieved almost immediately after the procedure," said Callaghan, now 57. "It was truly remarkable. I was able to play golf that summer. I could stand up straight and walk pain-free." Ever the fighter, Tom has also exhibited remarkable improvement during the six years since his diagnosis. "I have an immense and renewed appreciation for life and all that goes with it. Every day is precious," Tom remarks.

Balloon Kyphoplasty, pioneered by Kyphon, is a minimally invasive spine procedure that has been demonstrated to achieve sustained vertebral body height restoration and angular deformity correction in patients with vertebral body compression fractures caused by osteoporosis, cancer, and benign lesions. The procedure is associated with significant and maintained reduction in back pain, improvement in quality of life, and increase in ability to perform activities of daily living and patient mobility. As with most surgical procedures, there are risks associated with kyphoplasty, including serious complications, although the complication rate with balloon kyphoplasty has been demonstrated to be low.

"I am very proud to play a role in helping our physician customers deliver substantial quality of life improvement to patients like Tom, who suffer terribly from diseases like multiple myeloma," commented Richard Mott, president and chief executive officer of Kyphon Inc. "Since the procedure was launched in 2000, over 100,000 patients have been treated."

Callaghan and Mott will be interviewed about Balloon Kyphoplasty on Monday, December 6, 2004 on American Health Radio, a nationally syndicated health radio program hosted by Scott Broder. The program will air live at 6:00 p.m. Central Standard Time on Monday, December 6, and can be accessed at http://www.wrmn1410.com. A replay of the program will be available on Wednesday, December 8, at 8:00 p.m. Central Standard Time and on Friday, December 10, at 6:00 p.m. Central Standard Time.
