      abstract = {Lumbar spine problems are conditions of great significance  in the United States.  In the  American working-age  population, low back and leg pain is the number one cause  of disability.  Direct medical costs related to back pain  have been estimated at $25 billion per year, and the costs  to society are even higher. This project aimed to explore  the relationship between payer status and practice  variation in lumbar spine surgery in Oregon.},
