Spinal cord stimulation (SCS) has been widely used in the treatment for chronic refractory neuropathic pain. Although it may be effective and convenient, the implanted pulse generator that is the internal power supply chain of SCS involves cost and surgical risk when the implanted battery is depleted and needs to be replaced. We review a patient who was implanted an internal pulse generator with a non-rechargeable battery. The non-rechargeable battery was chosen due to quadriplegia after spinal cord injury, and was expected to function for several years. However, the device was stopped functioning 3 months after the implantation. The electrodes of SCS were activated at higher frequency due to quadriplegia, resulting in increased energy consumption, which shortened battery longevity. Therefore, it is important to calculate in advance estimated life of the battery when inserting SCS. We should choose a rechargeable battery if the required energy is high.
