Low Scoliosis Revision Surgery Rate Seen at Center

Last Updated: September 18, 2009.

In patients with idiopathic scoliosis who undergo primary fusion surgery, reoperation rates may vary greatly between institutions, according to a study in the Sept. 15 issue of Spine.

FRIDAY, Sept. 18 (HealthDay News) -- In patients with idiopathic scoliosis who undergo primary fusion surgery, reoperation rates may vary greatly between institutions, according to a study in the Sept. 15 issue of Spine.

Scott J. Luhmann, M.D., of Washington University School of Medicine in St. Louis, and colleagues studied 1,057 patients who underwent surgery at a mean age of 14.4 years and followed them for a mean of 5.7 years.

The researchers found that the reoperation rate was significantly lower than the rate reported in a previous study (3.9 versus 12.9 percent). They also found that the most common indications for reoperation were infections (34 percent), pseudarthroses (26 percent), and postoperative curve progression of the adjacent unfused spine (17 percent).

"Multiple patient, surgeon, and institutional factors are likely to account for marked differences in the reoperation rates after primary spinal fusion for idiopathic scoliosis at various medical centers," the authors conclude.

The study was supported by corporate and industry funds; at least one author reported a financial relationship with a study sponsor.
