Despite humanity’s long experience with amputations, postamputation pain remains a highly prevalent, incompletely understood, and clinically challenging condition. There are two main types of postamputation pain: residual limb pain (including but not limited to the “stump”) and phantom limb pain. Despite considerable overlap between the two, they also have distinct clinical features, risk factors, and pathophysiological mechanisms. Central, peripheral, and spinal mechanisms may all contribute to the protean manifestations of persistent postamputation pain; an improved understanding of these mechanisms will be essential to identify the most promising interventions for the prevention and treatment of postamputation pain. Although there are currently no standardized prevention or treatment recommendations for any type of postamputation pain, an evidence-based, multimodal strategy including pharmacological agents, nonsurgical procedures, surgery, complementary and integrative techniques, and assistive technologies may prevent the development of chronic postamputation pain after amputation and/or optimize treatment outcomes.
