The Spine Journal's impact factor has experienced steady growth in the past few years, going from a rating of 2.902 in 2009 to 3.290 in 2011.
Impact factor is based on two elements: the numerator, which is the number of cites in the current year to any items published in the journal in the previous two years; and the denominator, the number of substantive articles, or source items, published in the same two years, according to a research paper on the topic.
Eugene J. Carragee, MD, a spine surgeon at the Stanford University School of Medicine, is the editor in chief of the journal, which is the scientific publication of the North American Spine Society.
"Under the thoughtful and courageous stewardship of Dr. Carragee and its editorial team, The Spine Journal has elevated and protected the integrity of scientific publishing, and most importantly, the health and safety of patients everywhere," said NASS President Michael H. Heggeness, MD.
