人工颈椎间盘置换术(ARTIFICIAL CERVICAL DISC REPLACEMENT (PCM))

人工颈椎间盘置换术,是用人工椎间盘假体,替代受损的颈椎间盘,解除突出椎间盘或骨赘对脊髓和神经的压迫,保留病变颈椎间隙的活动度。

Overview(概述)

  (Caution: Investigational Device)(注意:试验性设计产品)

  A goal of this procedure is torelieve the pain caused by pinched nerves due to a damaged disc in the cervical spine. The diseased or damaged disc will be replaced with a specialized implant.

  人工颈椎间盘置换术的目的是治疗因颈椎的椎间盘损伤导致神经受压而出现的疼痛。术中,用特殊的内植物来替换病变或受损的椎间盘。

Removing the Disc(去除椎间盘)

  The surgeon s a small incision in the front of the neck to gain access to the spine. The diseased disc is removed from between the vertebral bodies.

  术者在颈前部作一小切口以显露脊柱。首先将椎体间的病变椎间盘去除。

Preparing the Vertebrae(准备椎体)

  The surfaces of the vertebral bodies are cleared of all damaged disc tissue and shaped to accept the implant.

  将椎体表面所有受损的椎间盘组织去除,并塑形以容纳内植物。

Implanting the Disc(植入椎间盘)

  The PCM? artificial disc is inserted into the space between the vertebrae and carefully tapped into place. The endplates are designed to bond tightly to the vertebral bodies, stabilizing the spine.

  将PCM人工椎间盘插入到椎间隙,并小心地敲击到位。所设计的终板可紧紧地与椎体相结合,从而稳定脊柱。

Alternative Treatment: Spinal Fusion(替代治疗:脊柱融合)

  The spinal fusion procedure uses a metal plate to connect the vertebrae above and below the removed disc.

  脊柱融合术是用金属接骨板连接椎间盘切除的上下两个椎体。

PCM® Artificial Disc(PCM®人工椎间盘)

  The PCM® implant is designed to preserve motion.

  PCM®假体设计用于保留脊柱的运动功能。
