Current strategy for chronic pain after spinal surgery

ABSTRACT

Failed back surgery syndrome was recently renamed, as chronic pain after spinal surgery (CPSS) by international classification of disease-11. CPSS is a challenging clinical condition. It has a variety of causes associated with preoperative, intraoperative and postoperative periods. Also, psychosocial factors should be considered. Diagnostic tools must be used differently, for each patient. Imaging and interventional nerve block for diagnosis, should be used properly. Strategy of management requires a multidisciplinary approach. The effect of conservative management (medication, interventional management) and invasive procedure (spinal cord stimulator, intrathecal drug delivery system) has been studied by many researchers. However, an evidence-based guide on management of CPSS, remains necessary, and further research is needed. This review focuses on understanding and clinical approaches for CPSS.
