Eighteen months after implantation of a C6-C7 cervical artificial disc (ProDisc-C; DePuy Synthes), a 44-year-old woman presented with right-sided C7 radiculopathy. Imaging revealed posterior subsidence of the prosthesis, with C7 foraminal stenosis. An ultrasonic curet was used to safely and effectively extract the prosthesis without neurologic complication; safe access for the insertion of an intervertebral cage was facilitated.
The ultrasonic curet was a safe and effective adjunct for revision artificial cervical disc replacement surgery; this technique may help to reduce potential injury to neural structures in a procedure with a traditionally high complication rate.
一名44岁女性在植入C6 - C7颈椎人工椎间盘（ProDisc - C；Depuy Synthes）18个月后，出现右侧C7神经根病。影像学检查显示假体向后沉降，伴有C7椎间孔狭窄。使用超声刮匙安全有效地取出了假体，未出现神经并发症；为插入椎间融合器提供了安全通道。
超声刮匙是人工颈椎间盘翻修手术中一种安全有效的辅助工具；该技术可能有助于在传统上并发症发生率较高的手术中减少对神经结构的潜在损伤。
