Total or artificial disc replacement is a procedure that aims to maintain the intervertebral disc height while restoring the physiologic motion a person would have with a healthy disc. This video provides step-by-step information on total disc replacement. 人工椎间盘置换术目的在于维持椎间盘高度，保留正常椎间盘所具有的生理活动。本视频逐步展示有关椎间盘置换的知识。  警告：请在有WIFI的场所观看视频，土豪请随意。
Total Disc Replacement Back Surgery 人工腰椎间盘置换术 Overview（概述） One goal of this procedure is to relieve the pain caused by pinche nerves or discogenic pain in the lumbar spine by replacing a diseased or damaged disc with specialized metal and polyethylene implants. 该手术的目的之一是使用特殊金属材料和聚乙烯内植物更换病变受损的椎间盘，以缓解神经压迫引起的疼痛或椎间盘源性腰痛。 Disc Removed（去除椎间盘） Through a small incision in the abdomen, the diseased disc is removed from between the vertebral bodies. 通过腹部小切口，将病变椎间盘从两个椎体之间去除。 Debris removed（去除碎片） The end surfaces of the vertebral bodies are cleared of all diseased disc cartilage and readied for the metal endplates of the prosthesis. The vertebral bodies are spred apart to relieve the pressure on the pinched nerve root and to accept the prosthesis. 椎体表面病变的椎间盘软骨清除干净，为假体的金属终板作准备。椎体之间撑开，以缓解受累神经根的压迫并接纳假体。 Implant Inserted（植入内植物） Metal implants of the appropriate size are selected, inserted into the opening, and tapped into position. 选择合适型号的金属内植物，植入椎间隙，并轻敲到位。 Core Inserted（植入内核） The polyethylene sliding core is inserted between the endplates. 在金属终板间植入聚乙烯滑动内核。 End of Procedure（手术结束） The spine is returned to normal posture, which seats the endplates in the vertebrae bones and holds the sliding core in position. The position of the prosthesis is carefully evaluated visually and with X-rays. 脊柱恢复正常姿势，金属终板紧靠椎体骨质并将滑动内核维系在位。通过观察X线仔细评估假体位置是否合适。 （高晨珉 转） |
