Targeted Interventional Therapies for the Management of Postamputation Pain: A Comprehensive Review

Postamputation pain (PAP), including residual limb pain (RLP) and phantom limb pain (PLP), remains a significant and debilitating complication after limb loss. Despite advances in pharmacological management, many patients experience inadequate pain relief, underscoring the need for alternative therapeutic strategies. Objective: This narrative review critically synthesizes current interventional therapies for PAP, focusing on mechanisms, clinical efficacy and practical application. Methods: A literature search was conducted in PubMed, EMBASE, Scopus and Web of Science databases for studies published between 2015 and 2025. Relevant articles on peripheral nerve interventions as well as different neuromodulation techniques were included. Results: Peripheral interventions (such as alcohol neurolysis, radiofrequency ablation (RFA) and cryoneurolysis (CNL)) and neuromodulation techniques (including spinal cord stimulation (SCS), dorsal root ganglion (DRG) stimulation and cauda equina stimulation (CES)) demonstrate promising outcomes for PAP. Peripheral nerve stimulation (PNS) shows favorable safety and efficacy profiles and may help prevent the chronification of pain. Conclusions: Contemporary interventional therapies represent valuable options in the multidisciplinary management of PAP. Nevertheless, further research is required to standardize clinical algorithms, optimize therapeutic decision-making and improve long-term outcomes and quality of life for individuals with PAP.
