ReviewIntrathecal pain pumps: indications, patient selection, techniques, and outcomes.
Intrathecal drug delivery represents an advanced modality for refractory chronic pain patients as well as intractable spasticity. This article reviews the advantages and indications for intrathecal therapy, as well as recommendations for proper patient selection using a multidisciplinary team to provide a global assessment of the impact of chronic pain on the patient's well-being. The goals and expectations of trialing are discussed alongside advantages and disadvantages of several trialing techniques. A discussion of outcomes is presented for patients with chronic pain due to both malignant and nonmalignant causes.

The article discusses chronic pain rehabilitation and describes its components and some of the core operating principles. Outcomes in chronic pain are best when multiple treatment strategies with a focus on functional restoration are employed, and this is often best done in an interdisciplinary pain rehabilitation program.

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.
