Ischemia is an important etiology of painful neuropathies. We generated a mouse system of ischemic neuropathy by ligation‐reperfusion of the femoral artery to mimic neuropathic pain and nerve injury patterns observed clinically. Mice exhibited spontaneous neuropathic pain behaviors, which were most obvious after ischemia for 5 h. Mechanical and cold allodynia developed by post‐operative day (POD) 7 and persisted through the experimental period up to POD 56. Neuropathic pain behaviors were alleviated with intraperitoneal gabapentin (50 and 100 mg/kg) in a dose‐dependent manner. Large‐fiber deficit assessed with nerve conduction studies was demonstrated by reduced amplitudes of the compound muscle action potential (CMAP) on POD 7 (48.4% of the control side, p < 0.001). Small‐fiber impairment was demonstrated by decreased epidermal nerve density (END) on POD 7 (29.1% of the control side, p < 0.001). Reductions in CMAP amplitudes and ENDs persisted through POD 56. Our system replicated the clinical manifestations of ischemic neuropathy: (1) neuropathic pain with cold and mechanical allodynia and (2) nerve injury to both large and small fibers with pathologic and physiologic evidence. This system produced by a simple procedure provides an opportunity to investigate mechanisms and further treatments of ischemic neuropathy on genetically engineered mice.
