Suffering from an aching back, truck
driver Mikel Hehn went to see surgeon Jeffrey Gerdes in 2008.
The St. Cloud, Minnesota, doctor diagnosed spinal disc
degeneration, commonly treated with physical therapy, and said
surgery wasn’t called for.
Unhappy with the answer, Hehn turned to a money grubbing slime Ensor Transfeldt, a
surgeon at
Twin Cities Spine Center in Minneapolis. Transfeldt
performed fusion surgery on Hehn, screwing together three
vertebrae in his lower spine.

Fusion aims to limit painful spine movements. This one
didn’t work out. Two years later, the pain in Hehn’s neck, lower
back, buttocks and thighs is so bad that he can’t hold a job and
seldom leaves home, he said in an interview.
“There’s days when I just can’t take it and the tears
run,” said Hehn, 52, who lives in Sartell, Minnesota. He said
he takes oxycodone for pain, Soma to sleep,
Lexapro for
depression and Imitrex for headaches.
Hehn’s surgery generated a $135,786 bill from Abbott
Northwestern Hospital in Minneapolis, feeding a national boom in
costly fusion surgeries. It also illustrates how spine surgeons
have prospered from performing fusions, which studies have found
to be no better for common back pain than physical therapy is --
and a lot more dangerous.
The number of fusions at U.S. hospitals doubled to 413,000
between 2002 and 2008, generating $34 billion in bills, data
from the federal
Healthcare Cost and Utilization Project show.
The number of the surgeries will rise to 453,300 this year,
according to Millennium Research Group of Toronto.
Unnecessary Surgeries
The possibility that many of these and other surgeries are
needless has gotten little attention in the debate over U.S.
health care costs, which rose 6 percent last year to $2.47
trillion. Unnecessary surgeries cost at least $150 billion a
year, according to John Birkmeyer, director of the Center for
Healthcare Outcomes & Policy at the University of Michigan.
“It’s amazing how much evidence there is that fusions
don’t work, yet surgeons do them anyway,” said Sohail Mirza, a
spine surgeon who chairs the Department of Orthopaedics at
Dartmouth Medical School in Hanover, New Hampshire. “The only
one who isn’t benefitting from the equation is the patient.”
The Twin Cities Spine bill for Hehn’s surgery was $19,292,
his medical records show. The firm received $8,978 after an
insurance discount, $7,742 of it for Transfeldt’s services.
Hehn’s insurer paid after his
bid for workers’ compensation
coverage was denied on grounds he wasn’t injured on the job.
Royalties, Consulting Fees
Another beneficiary was
Medtronic Inc., which makes
products for spinal surgery, including Infuse, a bone-growing
material widely used in fusions. Infuse accounted for $17,575 of
Abbott Northwestern’s charges, Hehn’s medical bills and
insurance records show.
Infuse, approved by the U.S. Food and Drug Administration
in 2002, had sales of $840 million last year.
Medtronic paid six of the 10 Twin Cities Spine surgeons --
including Transfeldt -- $1.75 million in royalties and
consulting fees in the first nine months of this year. It also
makes other financial contributions to the firm.
“Product usage is not a part of any development or
consulting relationship” between Medtronic and doctors, said
Brian Henry, a company spokesman.
Eleven Twin Cities Spine fusion patients, most of whom
tried to get or hold onto coverage benefits through the
Minnesota Workers’ Compensation Court of Appeals, said in
interviews that the surgery did nothing to relieve their back
pain, and in several cases left them worse off than before.
Hooked on Morphine
The patients illustrate the costs and risks of fusion
surgery. They are not a scientifically representative sample of
Twin Cities Spine patients, the majority of whom the firm says
are happy with the treatment they receive.
One of the 11 died of a methadone overdose when his pain
worsened after surgery and he couldn’t afford prescription
painkillers, his mother said. Another patient said he is hooked
on morphine to ease the burning sensation in his back where
screws and rods were implanted in an operation that cost his
insurer $60,000.
Twin Cities Spine performs fusions on patients with
conditions the surgery doesn’t treat effectively, said Brian
Nelson, an orthopedic surgeon and medical director of a
Minneapolis clinic that
stresses exercise for back pain. Nelson
said he used to perform fusions and has been in the operating
room with at least three of the 10 Twin Cities Spine surgeons.
“I have a lot of respect” for the practice and its
surgical skills, Nelson said. “But we have a fundamental
disagreement. I think there are too many people being fused.”
Risk Warnings
Payments by medical-device makers pose an “irresistible”
temptation to tailor treatment to more-lucrative procedures,
said Eugene Carragee, chief of spine surgery at Stanford
University in Palo Alto, California. “There is precious little
in human nature to suggest this proposition is unlikely.”
Twin Cities Spine believes in a “conservative course of
treatment in the vast majority of cases,” according to an e-
mailed statement from Lisa Arrington, the practice’s marketing
director. There are some people for whom surgery is appropriate,
she wrote, and numerous patients “have experienced successful
outcomes from spinal fusion procedures,” regaining
functionality. The operations “reduced pain and improved their
quality of life,” she said.
The firm declined to comment on individual patients, and
did not make the doctors who treated them available for comment.
Twin Cities Spine surgeons routinely warn of potential surgical
risks, including nerve damage, blood clots and the need for more
surgery, according to letters provided by several patients.
Degenerative Disc Disease
Financial relationships with medical companies are
disclosed to patients and do not influence whether surgery is
performed, according to the statement from Arrington. Royalties
are not received by Twin Cities Spine doctors on devices they
use in surgery, the e-mail said.
Fusion has helped spine surgeons become the best paid
doctors in the U.S. Their average annual salary is $806,000,
more than three times the earnings of a pediatrician, according
to the
American Medical Group Association, a trade organization
for doctor practices.
One of the most common causes of back pain is degenerative
disc disease, or the breakdown in the soft, puck-shaped cushions
between the vertebrae. Pain also comes from a condition called
stenosis, or the narrowing of the spinal canal, which can be
caused by bulging discs or arthritis.
Narcotics For Pain
British and Norwegian researchers found fusion no better
than physical therapy for disc-related pain in three studies,
totaling 473 patients, published in the journals Spine, Pain and
the British Medical Journal between 2003 and 2006. A 2001
Swedish study of 294 patients in Spine found fusion better than
physical therapy that was less structured than the kinds used in
the other studies.
Rates of complications from surgery in three of the
European studies -- including bleeding, blood clots, and
infections -- were as high as 18 percent. None reported
complications from physical therapy. The four studies are cited
in journals as the only head-to-head, randomized comparisons
between the two treatments.
In a U.S. study in Spine in 2007, surgeons reported fusion
was successful in only 41 percent of 75 patients suffering from
lower-back disc degeneration. Success measures included pain
reduction. Two years earlier in the same journal, surgeons found
a 47 percent success rate among 99 patients, 80 percent of which
were taking narcotics for pain two years later. Both studies
compared fusion to artificial disc replacement in trials
submitted to the FDA.
Evidence ‘Lacking’
Evidence that fusion is better than a simpler procedure
called decompression for stenosis is “lacking,” a study in the
Journal of the American Medical Association found earlier this
year. The study also found that fast-growing complex fusions --
those joining more than three vertebrae -- carried a 5.6 percent
risk of life threatening complications, more than double the 2.3
percent rate for decompression, which usually involves cutting
away damaged discs or bone pressing on spinal nerves.
Twin Cities Spine performs 3,000 spine surgeries a year,
1,300 of them fusions, and accounts for 75 percent of the spine
operations at
Abbott Northwestern, according to Daryll Dykes, a
surgeon in the practice. More than 4,000 spine procedures a year
are performed at Abbott Northwestern, the most of any U.S.
hospital, according to its website.
The practice generates big bills. Medica Health Plans, one
of Minnesota’s largest insurers, says it pays a median of
$26,021 for back surgeries performed by Twin Cities Spine,
including hospital and doctor fees. The medians range between
$12,814 and $23,546 for all other spine and orthopedic practices
in the area, Medica says.
Porsches, Ferrari, Mercedes
One Twin Cities Spine surgeon, Manuel Pinto, 56, earned
$1.85 million from the practice in 2007, according to filings in
his divorce proceedings that year. He told state superior court
in Minneapolis that he and his wife’s assets included two
Porsches; a Ferrari 430 coupe; a Mercedes Benz; two other cars;
three boats and proceeds from the $1 million sale of a farm
where the Pintos bred Lusitano horses.
Pinto’s 7,185-square-foot house presides over a wooded
promontory on Lake Minnetonka. Valued at $4 million in 2007, the
house has a swimming pool and 50 yards of beach.
In addition to Transfeldt, Pinto is one of the six surgeons
who receive payments from Medtronic. The others are Francis
Denis, Timothy Garvey, Joseph Perra and James Schwender.
Schwender, 44, earned $1.2 million from the practice and
$440,000 from royalties and consulting in 2008, divorce filings
show. Schwender bought his lakefront home outside Minneapolis
for $2.6 million in 2005, according to real estate records.
‘90 Percent Success’
Twin Cities Spine performed 1,100 lumbar, or lower-back,
fusion surgeries in 2009, Dykes said. Of those, he added, 380
patients had degenerative disc disease and another problem such
as stenosis, and 282 had degenerative disc disease alone.
Twin Cities Spine doesn’t have any scientifically validated
studies on the success of fusion for those in the latter group,
Dykes said. He called them “the controversial patients.”
Spinal fusion on back-pain patients is performed as a last
resort after less invasive treatments fail, he said. Measuring
outcomes has been difficult because researchers, doctors and
payers can’t agree on criteria for success, he said.
“Living Well With Back Pain,” a 2006 consumer guide
produced by Twin Cities Spine and published by HarperCollins,
states that, “With proper patient selection and optimal
surgical techniques, the success rate for spinal fusion surgery
for back pain is now about 90 percent.”
Two-Level Surgery
A letter from Pinto to patient Robin Washburn in 2005 said
surgery offered “a very good chance” of success, adding that a
“good to excellent outcome” would mean at least a 70 percent
reduction in pain.
Two spinal fusion surgeries later, her back is worse than
ever, said Washburn, who is 40 and a 911 dispatcher in Grand
Rapids, Minnesota. Washburn’s insurer, Blue Cross Blue Shield of
Minnesota, paid $80,000 for the two procedures.
“Before it was annoying. Now, it’s pain every day, all
day, worse when it’s cold,” she said in an interview.
Ninety-eight percent of Twin Cities Spine’s post-operative
patients who responded to a 2009 survey would choose or
recommend the group for surgical care, according to Arrington’s
e-mailed statement. She said about a third of patients responded
to the survey.
Patients that the practice recommended to Bloomberg News
for interviews reported being happy with their surgeries. One of
them, Jody Rasmusson, 48, of Minneapolis, underwent her second
spinal surgery in three years by Dykes in October 2009. One year
after the two-level fusion and decompression, the shooting pain
in her back and legs was gone, said Rasmusson, a bank customer-
service agent. A level is the space between two vertebrae; a
two-level surgery means three vertebrae were fused.
Playing Football
Before Robert Gumatz, 60, had a five-level spinal fusion by
Dykes in November 2009, the grain-company manager had so much
back and hip pain he was losing the use of his legs, he said. He
had stopped playing soccer with his kids and taking nightly
walks with his wife. A year later, “I can play tackle football
if I want to,” said Gumatz, of Oakdale, Minnesota. “I know I’m
an exception. I have no pain.”
For 50 years, surgery was a calling at Twin Cities Spine.
Led by surgeon John H. Moe, a pioneer in correcting scoliosis,
or abnormally curved spines, the group’s doctors rebuilt the
twisted backs of
children with polio and other malformations --
vertebra by vertebra.
They traveled at least 90 days a year, often paying their
own way, to show doctors around the world how to mend childhood
spinal deformities, said David Bradford, who spent 20 years at
the practice before becoming chair of orthopedics at the
University of California at San Francisco in 1991.
Adapting Fusion
At home, Bradford said surgeons operated weekly at Gillette
Children’s Hospital in St. Paul, Minnesota, usually for free.
“‘It was just what you did; that’s why we became doctors,”
said Bradford, now a professor and chair emeritus at UCSF’s
spine center. “We weren’t in medicine to make gazillions.”
While senior surgeons continue to research and treat
crippling disease, Pinto and other protégés have also adapted
the fusion techniques Moe pioneered to surgery for common back
pain, said Robert Winter, the firm’s research director.
Twin Cities Spine surgeons published articles on fusion
techniques for back pain and presented results at professional
meetings. Its financial relationship with
Medtronic, the largest
maker of spinal implants in the U.S., began as early as 2002,
when, according to a deposition by Pinto, he began receiving
money from the company, which is based in Fridley, Minnesota.
Medtronic Money
In addition to the $1.75 million it paid the six Twin
Cities Spine surgeons this year, Medtronic and three other
device companies give the practice a total of $100,000 to
$500,000 for a fellowship program, Arrington said. Twin Cities
Spine calls it the largest such program in the country and says
it has trained 140 spine surgeons.
Medtronic also has
disclosed contributing $150,000 in 2008
to a non-profit that Schwender heads to spread the use of
minimally invasive surgical devices. The contribution
represented 95 percent of the non-profit’s expenses that year,
according to the organization’s latest-available tax filings.
In 2004, Pinto was seeing Jean Kingsley, 57, a patient who
had had two previous fusion surgeries and was still suffering
back pain. Pinto told her, according to a hospital report he
wrote, that more “surgical treatment could provide her with
some relief of her pain” if her symptoms “were extremely
severe, unrelenting” and had “failed extensive conservative
care,” which “appeared to be the case.”
Not Negligent
Her third operation, a daylong procedure by Pinto in
September of that year, fused 13 vertebrae along her entire
spine and was a disaster. Kingsley, of Milaca, Minnesota,
returned home paralyzed from the waist down, according to
hospital records in a lawsuit she brought against Pinto. A jury
in Minnesota state court found earlier this year that Pinto was
not negligent in the case.
The judge awarded $46,616 in attorney’s fees to Pinto,
which Kingsley said she can’t pay. She has appealed the
decision. Her case is a “unique set of events for which even in
retrospect there is no obvious explanation that one can prove,”
Pinto said in his 2008 deposition, in which he estimated he
performed 400 to 500 back surgeries a year.
Abbott and Twin Cities Spine billed a combined $239,000 for
the surgery, Kingsley’s records show. Insurer Medica says it
paid about a third of that amount after a discount.
Kingsley arrived home in a wheelchair, wore a diaper for
two and a half years and had a home health aide visiting to
bathe her in bed, she said in a deposition in the case. As her
condition improved, she said she was able to move short
distances with the aid of leg braces and a walker.
‘I’m Paralyzed’
Today, Kingsley lives alone after the 2008 death of her
husband. She said she takes medication for depression and
doesn’t do “much of anything,” usually watching television and
reading, and lives off Social Security benefits from her
husband’s death. “Now I don’t feel any pain,” Kingsley said in
an interview. “I’m paralyzed.”
Pinto co-authored a study in Spine in 2009 on 125 of his
patients who had, like Kingsley, undergone fusions of four or
more vertebrae. The study, which a Twin Cities Spine fellow
presented at six surgical conferences around the globe,
concluded that patients with extensive degenerative pain “can
be successfully treated with surgical intervention.”
The Pinto study showed why back-pain patients should avoid
spinal fusions, said Stanford University’s Carragee. The paper
tracked progress in only 80 of the 125 surgical patients; “what
happened to the other 45 patients?” Carragee asked.
Lifting a Keg
Twenty-seven of the 80 patients needed a second surgery,
while about 40 percent of the patients had complications,
including 5 percent of the men who suffered permanently
diminished sexual function, Carragee said.
“This should make you pretty cautious about doing this
kind of stuff,” he said.
Twin Cities Spine, in its statement, said Pinto’s study was
the first to report on such extensive fusion surgery for
degenerative back pain, an operation it said “is in no way
comparable” to less complicated procedures.
Schwender first performed fusion surgery on Catherine
Engels in May 2001, after finding she had a herniated disc. She
came to see him again on June 4, 2003, complaining of sharp back
pain, her medical records show.
Engels, now 50, received Schwender’s support for a workers’
compensation claim, in which she said she injured her back
lifting a keg at a liquor store where she worked in July 2000.
Schwender said in a deposition that the incident was “a
significant contributing factor” to Engels’s back problems.
‘
Constant, Sharp Pain’
The workers’ compensation judge
rejected her claim, finding
“multiple significant inconsistencies” between her and
Schwender’s testimony, on one side, and the medical records
submitted by six doctors Engels saw before Schwender, on the
other. Two of those doctors said Engels hadn’t attributed her
back pain to any specific injury, and others said Engels
attributed the pain to lifting patio brick, the judge found.
Schwender operated a second time on Engels in January 2004,
removing the screws and rods he’d put in her spine and
decompressing the spinal canal. It didn’t help. By then,
Schwender told Engels, the rods and screws had shifted and
caused permanent nerve damage, she said in an interview. Now she
has “constant, sharp pain” down her left leg, treated with
drugs and a neurostimulator in her back designed to send out
current that interferes with pain signals.
“I went through with fusion thinking it would be the cure-
all,” Engels said. “It wasn’t.”
OxyContin, Hydrocodone, Elavil
Dan Bebault was suffering from lower back and leg pain when
he visited Twin Cities Spine’s Garvey in May 2006. Garvey
discussed surgery with him and told him he’d “likely” be able
to return to light work three to six months afterwards,
according to Bebault and notes Garvey made on the case. “He
pretty much talked me into it,” Bebault said.
The fusion took place in August that year. When Bebault
returned to see Garvey five months later, he said, his life was
falling apart. The pain had spread to his neck and arms, and
OxyContin, hydrocodone and Elavil weren’t helping much.
Bebault’s wife had left him after the surgery; he hadn’t worked
in four years.
Garvey wasn’t sympathetic, said Bebault, a 53-year-old
former machinist who lives in Brooklyn Park, Minnesota. “He
said my life was like an old country-western song and he didn’t
want to hear about it,” Bebault said in an interview at his
home. “He said come back if I want more surgery.”
Methadone Overdose
Additional fusion surgery for Bebault’s neck “would be an
option,” Garvey’s chart notes from this time say. Bebault, now
reunited with his wife and on Social Security disability,
decided against more surgery and quells the pain in his back and
neck with 120 milligrams a day of morphine, plus occasional
vicodin, valium and amitriptyline, an anti-depressant.
He said he feels “withdrawals” when his morphine wears
off, shaking and sweating. His surgery cost his former
employer’s
workers’ compensation insurer $48,633; Garvey’s fee
was $5,870.
“The patient is like a piece of meat; everybody’s making
money off the guy,” Bebault said.
Garvey did a three-level spinal fusion on Ross Tamminen in
April 2006. Six months later, Tamminen, a heavy-equipment
operator, reported severe pain again in his back and legs,
according to documents from a
case in state workers’ comp court.
As a treatment option, Garvey proposed more surgery to
examine the fusion site, remove the implants in Tamminen’s
spine, and perform decompression. His employer’s insurer denied
a coverage request, saying surgery wasn’t warranted, according
to court filings.
The rest of the story comes from Tamminen’s mother, Barbara
Grove. Denied federal disability benefits and in intractable
pain, Tamminen ran out of money for painkillers, she said, and
began taking methadone obtained through friends.
He died of an overdose on June 20, 2008, 26 months after
spinal fusion. He was 41.

if I did he'd kick my fat ass. About a minute later I spied a car turd. A
car turd is one of those big fucking brown ice chunks that fall from

and having no impulse control I picked up that icy fucker and fired it
at the that mouthy dip shit and it knocked him silly. He went on the
attack and not wanting to get pummeled I told him Proud threw it.
