Abelson, Reed. "The Spine as a Profit Center," New York Times, 30 December 2006, pp.
Spinal-fusion surgery is one of the most lucrative areas of medicine. An estimated half-million
Americans had the operation this year, generating billions of dollars for hospitals and doctors.
But there have been serious questions about how much the surgery actually helps patients with
back pain and whether surgeons' generous fees might motivate them to overuse the procedure.
Those concerns are now heightened by a growing trend among some surgeons to profit in yet
another way — by investing in companies that make screws and other hardware they install.
The parts can be highly profitable. A single screw that goes into the spine, for example, sells for
about $1,000 — at least 10 times the cost of making it.
Within the medical device industry, it has been well chronicled how companies use consulting
ties and other financial relationships to try to gain favor with the surgeons using their devices.
But critics are especially troubled by the emerging trend in spinal devices, which so far has
occurred largely under the radar.
Doctors' taking significant ownership stakes in spinal parts makers, critics say, provides an extra
financial incentive for a doctor to recommend a surgery. It may be one of the most distinct
examples yet of the way monetary considerations can play a role in the way doctors practice
Such doctors face "an awfully pernicious conflict of interest," said Dr. Richard A. Deyo, a
physician and health services professor at the University of Washington in Seattle.
About 30 start-up companies have begun selling spinal devices, including screws, in the last
couple of years. And industry experts say about a dozen companies have doctors among their
investors. Because most of the companies are private and the relationships are not publicly
disclosed, there is no way to know how many spine surgeons around the country are partial
owners of device makers.
Typically, patients are not aware of the doctor's financial interests. One patient who is suing her
surgeon for malpractice learned only during the legal discovery process that her surgeon had a
financial interest in the maker of the artificial disk he installed in her spine.
Federal regulators have voiced concerns about the growing popularity of the investment
arrangements, which would potentially violate antikickback laws if doctors receive stock or are
otherwise compensated to use or recommend certain devices.
"This is an area that is new and growing," Vicki L. Robinson, a senior attorney in the Office of
Inspector General at the Department of Health and Human Services, said in an interview. In a
recent letter to a device industry trade group, Ms. Robinson wrote that the "ventures should be
closely scrutinized under the fraud and abuse laws."
Some spine surgeons are also concerned about whether they and their colleagues should enter
into such arrangements. "These are, I believe, unethical and bias the doctors' choice for what is
best for the patient," said Dr. Charles D. Rosen, a spine surgeon at the University of California at
Irvine, who is the president of the newly formed Association of Ethical Spine Surgeons. The
group has about 75 members so far, who have agreed not to invest in companies whose devices
But doctors who do sometimes use the products of companies in which they invest say they do
not let financial interests influence their medical judgment. Some surgeons and companies say
that patients can even benefit because the collaboration means the devices have been better
designed to meet their needs.
But industry experts say that that doctors' financial needs may be also be a big motive.
As surgeon fees have fallen over the years, doctors have been increasingly attracted to other
sources of revenue, said Dr. John Cherf, an orthopedic surgeon in Chicago who also advises
hospitals about health care trends. That is why many surgeons have invested in specialty
hospitals, he said.
And now, devices "are the low-hanging fruit," he said. "There's a lot of money in devices."
One of the fastest growing companies is Allez Spine, of Irvine, Calif. It was founded on a
business model that called for the 120 doctors who invested in Allez to serve as "its customer
base," according to a lawsuit filed by a former chief executive last April. Those doctors, who pay
$50,000 or more to become investors, own two-thirds of the company, according to legal filings.
Selling the company's screws to its "investor-doctors" was a way to "generate more profits for
the company" according to a related lawsuit involving the former executive.
At one midsize Nevada hospital, a surgeon who performs many spinal fusions is an Allez
investor who uses the company's screws, said an administrator. He spoke on condition of
anonymity because the hospital fears alienating its surgeons. While some doctors at the hospital
who invested in Allez choose not to use its screws, others seem "financially driven" to select
them, he said.
The identities of most of the surgeons who invest in Allez are not publicly disclosed. And the
doctors who could be identified and were called for comment did not return repeated telephone
Dr. Edward Geehr, president of Allez Spine, said that many of his surgeon-investors did not use
the company's products, although he declined to say how much of the company's sales came
from surgeons who were not also investors.
The company offers hospitals products at lower prices than the competition, Dr. Geehr said,
although he declined to discuss specific pricing.
The spinal device market, which has doubled in the last three years, is particularly attractive to
newcomers, said Stan Mendenhall, the editor of Orthopedic Network News, an industry
newsletter. Spinal screws are relatively simple to develop and cost only $65 to $100 to make, he
said, often by a supplier that handles the production of screws for a variety of companies.
There are about 100 companies in the spinal devices field, and some of the newest and fastest
growing have some level of doctor ownership, Mr. Mendenhall said.
Patients who find out about these ties can be upset, as was Patricia Kennedy, whose
disk-replacement operation in September 2002 was performed by Dr. Richard A. Balderston, a
spine surgeon in Philadelphia.
Ms. Kennedy says the surgery was unsuccessful and made her condition even worse. She is now
suing Dr. Balderston for malpractice, and the maker of the artificial disk, Spine Solutions, for
Ms. Kennedy says she did not fully understand that the disk was experimental. She discovered
only later that Dr. Balderston was an investor in a venture capital fund that owned Spine
Solutions at the time of the surgery. A lawyer for the company declined to comment.
The company and the doctor "failed to disclose that Dr. Balderston had a significant financial
interest in the outcome of the experiment," according to the lawsuit.
"I've really been guinea pigged and betrayed," Ms. Kennedy said in an interview.
A lawyer from the firm representing Dr. Balderston said the firm had a policy of not commenting
on pending litigation. The case is expected to go to trial in March, according to Ms. Kennedy.
Even hospitals where spinal-fusion surgeries are performed may not know when doctors own a
piece of a device maker. A few hospitals, though, require the device makers and doctors to tell
them about the arrangements.
At Hoag Memorial Hospital Presbyterian in Newport Beach, Calif., several doctors are investors
in Allez, including Dr. William Dobkin, a surgeon at the hospital. He did not return repeated
calls for comment.
"We use heavy disclosure practices with our vendors and our physicians to understand these
relationships," said Jennifer Mitzner, the chief financial officer for Hoag.
At the Tenet Healthcare hospital chain, the California hospitals it owns have signed a contract
with Allez that calls, among other things, for the doctors to agree to disclose any ownership
interests to their patients.
Allez says physicians who invest in the company and use its products in California disclose those
ties to patients. "All our relationships are disclosed," Dr. Geehr said.
Some of the new companies aim to recruit surgeons who perform a high volume of back
operations, according to doctors who have been approached. The exact nature of the investment
opportunity is left vague in the discussions, the doctors say, with details made available only to
those who agree to become investors.
One surgeon described being contacted by Globus Medical, a start-up company in Audubon, Pa.
The surgeon said he was not persuaded to use Globus screws and other hardware, despite the
sales representative's mention of the "good opportunities" available if he were to become a large
The policies of Globus forbid its representatives from offering stock to reward surgeons who use
their products, said Dave Demski, chief financial officer of Globus.
The doctors who do invest, Mr. Demski said, are doing so because they are interested in owning
stock in businesses they understand, like Globus. "It's really based on their enthusiasm for what
we're doing," he said.
At Alphatec Holdings, a company in Carlsbad, Calif., doctors are shareholders because they have
either invested directly or are paid in stock for consulting, according to filings by Alphatec,
which is one of the few publicly held companies among the small start-ups.
The chairman of Alphatec's scientific advisory board is Dr. Stephen J. Hochschuler, a prominent
surgeon who helped start the Texas Back Institute, one of the largest spine clinics in the country.
For his work as an adviser, Dr. Hochschuler received a restricted stock grant that was worth
about $640,000 when Alphatec went public in June, according to the company's public filings.
Because the share price has fallen, the grant — which vests over five years — is currently now
worth only about $270,000.
Dr. Hochschuler, in a written response to an interview request, said doctors should work closely
with device companies like Alphatec. "Surgeon involvement in the development of surgical
devices is paramount in the creation of these devices and techniques that allow our patients to
return to their lives in a more timely fashion, with less pain," he wrote.
Dr. Hochschuler's ties to the company do not influence his choice of devices, he said in a
follow-up e-mail message. He said he had used the Alphatec implants "probably less than 5 times
so that I thoroughly know and understand the pros and cons."
An Alphatec spokesman also said physicians played an important role in developing new
products. "There is a critical relationship between physicians and engineers at Alphatec," said the
spokesman, David Schull.
Some surgeons who have bought Alphatec stock argue that their holdings are no different than
their investments in any other company.
Dr. E. Claiborne Irby Jr., a surgeon in Richmond, Va., who invested in Alphatec before it went
public, says he uses its devices, but not exclusively. "I don't change anything I do because of any
kind of investment," he said.
But federal regulators and law-enforcement officials are on the lookout for surgeons who step
over the line.
Doctors "are supposed to make the decision based on the best interest of the patient," said Peter
Winn, a lawyer in the United States attorney's office in Seattle, who has aired his concerns in a
speech to spine surgeons.
To do otherwise, he said in an interview, "is a violation of the ethical rules, and it has been since
the time of Hippocrates."
