Im not a spinal surgery fan but it was comforting to read
 Anterior Lumbar Spine Surgery: A Systematic Review and Meta-Analysis of Associated Complications
According to the report “complication rates with anterior lumbar spine surgery are relatively low, with the most common complications occurring at a rate of 1-3%. Complication rates are related to surgical technique, approach, and implant characteristics. Further randomized controlled trails are needed to validate the use of preventative measures including CTA and the use of an access surgeon”
Still tough on the 1-3% though!
