ReviewNeurolysis, neurectomy, and nerve repair/reconstruction for chronic pain.
Neuropathic pain may be a result of focal injury to a peripheral nerve. The treatment algorithm begins with nonoperative, then operative, options. ⋯ Neurectomy is an option in primary cases where numbness is an acceptable alternative to dysesthetic pain, or as an alternative following failed neurolysis. Nerve repair or reconstruction may improve pain by guiding axons past the neuroma.

ReviewPercutaneous spinal cord stimulation for chronic pain: indications and patient selection.
Percutaneous spinal cord stimulation has a clinical benefit in selected patients with chronic neuropathic pain related to failed back surgery syndrome and complex regional pain syndrome. Patients with other peripheral neuropathic pain syndromes may also respond favorably. The cause of the chronic pain must be established to rule out remediable causes. ⋯ A psychological evaluation identifies patients who may not benefit. Risk factors for infection should be corrected where possible. This safe, reversible treatment should be considered early for patients with intractable peripheral neuropathic pain.

ReviewDeep brain stimulation for chronic pain: intracranial targets, clinical outcomes, and trial design considerations.
For over half a century, neurosurgeons have attempted to treat pain from a diversity of causes using acute and chronic intracranial stimulation. Targets of stimulation have included the sensory thalamus, periventricular and periaqueductal gray, the septum, the internal capsule, the motor cortex, posterior hypothalamus, and more recently, the anterior cingulate cortex. The current work focuses on presenting and evaluating the evidence for the efficacy of these targets in a historical context while also highlighting the major challenges to having a double-blind placebo-controlled clinical trial. Considerations for pain research in general and use of intracranial targets specifically are included.

Nerve blocks are often performed as therapeutic or palliative interventions for pain relief. However, they are often performed for diagnostic or prognostic purposes. ⋯ The most common nerve blocks for chronic pain and that may be applicable to the neurosurgical patient population are reviewed in this article. This article is an introduction and brief synopsis of the different available blocks that can be offered to a patient.
