Abstract:

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 medicine.
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 anti-kickback 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 they use.

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 calls. 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 product liability.

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 user.
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.”
