Detailed surgical management, magnetic resonance imaging (MRI), and computer tomography (CT) images of a broken annular closure device (ACD) have not been reported yet. In this case, a 28-year-old male presented with a new onset of radiculopathy three years after lumbar discectomy and placement of an ACD. The CT-myelography and MRI revealed a recurrent disc herniation (RDH) and dislocation of a broken ACD. ACD removal was performed and confirmed breakage due to RDH with scarring around the RDH and displaced ACD. Implant-associated complications and management should be reported in detail in order to enhance knowledge on device-related complications.
详细的手术管理、磁共振成像（MRI）和计算机断层扫描（CT）图像的环形封闭装置（ACD）破裂尚未报道。在这种情况下，一名 28 岁男性在腰椎间盘切除和 ACD 放置后三年出现新的神经根病。CT 脊髓造影和 MRI 显示复发性椎间盘突出症（RDH）和破裂的 ACD 脱位。进行了 ACD 切除，并证实由于 RDH 导致的断裂，伴有 RDH 周围的疤痕和移位的 ACD。应详细报告与植入物相关的并发症及其处理方法，以增强对器械相关并发症的认识。
