The third of three reviews of research on spinal surgery for neck pain was recently published by a group of well-known pain experts (van Middelkoop, et al., 2012; van Middelkoop, et al., 2013; Verhagen, et al., 2013). The investigators undertook the reviews of the research on different aspects of neck surgery because the most recent previous studies, done as Cochrane reviews (Fouyas, et al., 2002; Nikolaidis, et al., 2008), were now outdated. So, they systematically reviewed the latest published research on different types of spinal surgery for neck pain to determine whether and how such surgeries are effective. What they found was that spinal surgery for neck pain is not any more effective than other, less invasive, therapies.
