The post-amputation (pain) syndrome, including stump pain, phantom limb sensation, and phantom limb pain is common but difficult to treat. Refractory stump pain in the syndrome is an extremely challenging and troublesome clinical condition. Patients respond poorly to drugs, nerve blocks, and other effective treatments like spinal cord stimulation and surgery. Pulsed radiofrequency (PRF) technique has been shown to be effective in reducing neuropathic pain. This report describes a patient with persistent and refractory upper limb stump pain being successfully relieved with PRF of brachial plexus under ultrasound guidance after a 6-month follow-up period, suggesting that PRF may be considered as an alternative treatment for refractory stump-neuroma pain.
截肢后（疼痛）综合征，包括残端痛、幻肢感和幻肢痛很常见但难以治疗。该综合征中难治性残端痛是极具挑战性且棘手的临床病症。患者对药物、神经阻滞以及脊髓刺激和手术等其他有效治疗反应不佳。脉冲射频（PRF）技术已被证明在减轻神经性疼痛方面有效。本报告描述了一名上肢残端持续性难治性疼痛患者，在超声引导下接受臂丛神经PRF治疗后，经过6个月随访期疼痛成功缓解，提示PRF可被视为难治性残端神经瘤疼痛的一种替代治疗方法。
