Procedure of the Month

This is the case of a 68 year-old male suffering from severe back pain for 3 months. Patient failed conservative treatment with high doses of analgesics. MRI was performed, as shown in Figure 1 below. This T2-weighted image clearly revealed evidence of acute fracture with bone marrow edema at the L1 level. Which choice do you think best describes the patient's treatment options (click on the x-ray below to take the multiple choice/guess test)?

Elegance in Spine: Extracavitary Approaches
The delicate task of dealing with spinal problems is getting a bit less complex, says Dr. Francis Shen. Orthopedists can now remove a section of rib and approach the front of the vertebrae from the back in an oblique direction.

Endotec Beats FDA, Strikes Blow for Innovation
Endotec has struck a blow for every orthopedic surgeon who wants to develop a better device. See how the company’s founders took on the FDA and got a federal judge to charge the agency with “stymieing progress and technological advancement.” How did they do it? Read on.

From Obesity to Osteoarthritis, the Carpal Tunnel Connection
It’s certainly no surprise that Carpal Tunnel Syndrome (CTS) is an exceedingly common orthopedic malady. But, as PearlDiver’s data show, the linkage between obesity, osteoarthritis and other conditions to CTS is most surprising. Check it out.

Using DNA to Predict Scoliosis
Six million people (estimate from the National Scoliosis Foundation) have scoliosis in one form or another. The primary age for onset of idiopathic scoliosis is 10-15 years old. Finally, there is a test which can reliably predict scoliosis. Fewer X-rays. Lower cost. Better outcomes.

New Capital, New Science for Cartilage Repair
$36 million invested in the last couple of months. TiGenix has more than that in the bank to fund market penetration. Then a new paper last week finds molecular cause of OA. Cartilage repair momentum is building.

Should I Become a Physician-Employee?
Large healthcare institutions are increasingly purchasing orthopedic practices. What does this mean for patient referrals? How beneficial can it be for orthopedists? The upside is more stability, among other things…and one of the downsides is loss of freedom.

Outrageous Whistleblower Lawsuit Challenged
Spine surgeons sued by whistleblowers in Boston are fighting back. Their lawyer is outraged and says the claimants are just shopping an old and settled case to another judge. Is this the proverbial lipstick on a pig? Find out.

Medical Education Under the Microscope – Is It Up to Today’s Challenges?
Where is the line drawn between what medical schools, residencies, and professors should provide to students and what doctors-in-training should reach for themselves?

The Underlying Meaning of Zimmer’s Purchase of Abbott Spine

Resurging Lumbar and Cervical Total Disc Replacement Markets! New PearlDiver Estimates
Rumors of the TDA market’s demise were premature. Increasingly positive long term patient data is at the core of a resurging lumbar and cervical TDR market. Senior analyst Matt Menze tackles the TDA market and interviews one of the fathers of TDR, Dr. Scott Blumenthal from the Texas Back Institute. Where is this market actually heading? We think to the $2 billion range by 2015. All details here.

Six Days in June – Biomet and Zimmer Battle for Distributors in Kentucky
Documents filed recently in a Kentucky lawsuit pull the curtain back on an epic battle between Biomet and Zimmer. For six fevered days in June 2007, Biomet CEO Jeff Binder and founder Dane Miller went into the trenches to save one of their own. For all the details, read on.

Multicenter Clinical Trials: Do They Get the Respect They Deserve?
They’re not fast or sexy, but they are critical…large trials, that is. With multiple sites and principal investigators who donate their time, large trials are more complex—and normally yield more actionable data—than smaller, quicker studies. But large trials don’t always get the respect they deserve. And, says at least one physician-researcher, this could affect the future of the field.

Patent Wars: Medtronic Attacks NuVasive
MSD’s lawsuit came amid a period of declining spinal implant market share – from a peak of 60% in late 1998 (just prior to being acquired by Medtronic) to, we estimate, 36% currently – and a growing sense that MSD’s reign as the king of spine was coming to a close. What’s really behind Medtronic’s attack on its former senior exec? Read on.

Theken Spine Announces First Vu aPOD Surgery
By Elizabeth Hofheinz, MEd, MPH
July 30, 2008

No more wondering about wandering implants…Theken Spine has announced that Mukund Gundanna, M.D., of College Station, Texas, has performed the first surgery for the Vu aPOD™, the first anterior lumbar intervertebral fusion (ALIF) implant with an optional internal SpinPlate to receive FDA clearance. The outcome of the surgery is thus far positive.

According to the company, Vu aPOD uses the patient’s cortical bone in the anterior part of the vertebral body as a buttress when engaging the internal SpinPlate, enhancing implant stability. Theken received FDA clearance to market Vu aPOD in the United States in early July.

“The surgery went very well and the Vu aPOD was simple to use,” stated Dr. Gundanna in the news release. “The SpinPlate is like nothing I have used before. It reduces any concerns about implant migration. It truly provides better fixation for the patient.”

Commenting to OTW was Jack Maertens, VP Marketing, who noted, “The Vu aPOD is in limited release and is scheduled for full product launch in fall 2008. Upon full product launch, Vu aPOD will be available through Theken’s authorized independent distribution network.”
