Spinal cord stimulation is an important therapy option for the treatment of chronic neuropathic pain of spinal or peripheral etiology. As with any implantable device, complications may arise. These must be promptly identified and managed to maintain patients in successful therapy. ⋯ Lead migration is one of the most common complications of spinal cord stimulation, and left untreated can lead to loss of therapy and possible device explant. A strategy for correcting this issue is needed, and we present an unusual case to consider when faced with a loss of therapy from lead migration.

Chronic opioid therapy may lead to high level tolerance development, hyperalgesia, and central sensitization, which further complicates long-term therapeutic management of chronic pain patients. In this case, we encounter a patient who was receiving over 15,000 morphine milligram equivalents through their intrathecal pain pump. Unfortunately, the intrathecal pump was inadvertently cut during a spinal surgery. It was deemed unsafe to delivery IV equivalent opioid therapy in this case; instead, the patient was admitted to the ICU and given a four-day ketamine infusion. ⋯ Ketamine may play an important role in attenuating not only tolerance but also acute withdrawal in a setting where rapid or instant weaning from high dose chronic opioid therapy is needed.

Review Meta Analysis
Efficacy of epidural analgesia for intractable cancer pain: A systematic review.
Epidural analgesia is a common technique for managing perioperative and obstetric pain. Patients with cancer who cannot tolerate opioids or not responding to conventional treatment may benefit from epidural analgesia. Therefore, this systematic review aimed to analyze the efficacy and safety of epidural analgesia in patients with intractable cancer pain. ⋯ Coadministration of epidural opioids, local anesthetics, and adjuvants may provide better pain relief for intractable cancer pain. However, we must assess the patients to ensure that the benefits outweigh the risks before epidural analgesia. Therefore, further high-quality studies are required.
