ABSTRACT
The success of spine surgery is variable among patients. Finding reliable predictors of successful outcomes will not only maximize patient benefit, but also increase the cost effectiveness of surgery. Recent research has demonstrated the importance of patient specific factors in predicting patient outcomes, including gender. While many studies show that female patients present with worse pain and function pre-operatively, there is conflicting data on whether male and female patients reap the same benefits from lumbar spine surgery. In this manuscript we review the current research on gender and sex differences in pre-operative characteristics and post-operative outcomes and comment on the need for more studies to better elucidate the mechanism driving the conflicting evidence.
