Is Complex Regional Pain Syndrome a Cause of Post-Operative Syndrome in the Lumbar Spine? - A Case Report -

Complex regional pain syndrome (CRPS) along with post-operative syndrome in the lumbar spine shows confusing and duplicated symptoms, and this makes it difficult to make a clear differential diagnosis. Therefore, the patient with post-operative syndrome in the lumbar spine suffers losses of time and money, and the surgeon who diagnoses and treats post-operative syndrome in the lumbar spine also agonize from the patient's losses. It is necessary to provide these patients with a multidisciplinary approach to their disease and symptoms. We diagnosed herniation of an intervertebral disc of the lumbar spine (L4/5) and we performed discetomy twice in different hospitals. However, the symptoms did not improve, so we re-operated and performed discetomy along with monosegmental fixation using pedicular screws and interbody cages. There was improvement of pre-operation symptoms, but neurogenic symptoms occurred and then progressed after the surgery. Therefore, we report here on the case of CRPS that was diagnosed with the exclusion of the causes of post-operative syndrome in the lumbar spine, and the patient was finally effectively treated with spinal cord stimulation. Although differentiating post-operative syndrome in the lumbar spine from CRPS is difficult, we recommend suspecting CRPS as the cause of post-operative syndrome in the lumbar spine and taking CRPS as the main interest in order to diagnose and treat CRPS more effectively and accurately.
