An increasingly common surgical procedure for repairing spinal fractures might not be all it’s cracked up to be–in fact, the surgery had the same effect on patient’s pain as a placebo, two studies report in the New England Journal of Medicine.
The technique, called vertebroplasty, involves injecting medical cement into a fractured spine bone to strengthen it. More than 38,000 such procedures are done in the United States every year and the number has been [increasing] rapidly, nearly doubling from 2001 to 2005 [Reuters]. But the new studies showed that the procedure alleviated pain about the same amount as a placebo “surgery,” in which the physicians tapped on the spine and piped in the smell of cement to make groggy volunteer subjects believe they were receiving the real thing.
Researchers found that 36 volunteers who received sham surgery did just as well as 35 who got the real operation. A separate test, of 131 people at 11 medical centers, … also found that sham surgery produced a comparable degree of pain reduction and movement [Reuters].
