Management of Post-Amputation Pain.

Introduction: The prevalence of amputation and post-amputation pain (PAP) is rising. There are two main types of PAP: residual limb pain (RLP) and phantom limb pain (PLP), with an estimated 95% of people with amputations experiencing one or both. Medical Management: The majority of chronic PAP is due to phantom limb pain, which is neurogenic in nature. Common medications used include tricyclic antidepressants, gabapentin, and opioids. Newer studies are evaluating alternative drugs such as ketamine and local anesthetics. Rehabilitation Management: Mirror visual feedback and cognitive behavioral therapy are often effective adjunct therapies and have minimal adverse effects. Surgical Management: Neuromodulatory treatment and surgery for neuromas have been found to help select patients with PAP.

Conclusion: PAP is a complex condition with mechanisms that can be located at the residual limb, spinal cord, and brain - or a combination. This complex pain can be difficult to treat. The mainstays of treatment are largely medical, but several surgical options are also being studied.
