颈椎椎板成形术(Cervical Laminaplasty)

椎板开门手术,即椎板成形术,通过外科手术将椎板一侧或双侧切开,使椎板向后外侧移位以扩大椎管。最早由日本平林和中野报道,后经许多学者在实践中加以改进,并提出了改良的手术方法。

  Laminaplasty is a surgical procedure that treats a painfully restricted spinal canal by creating more space for the spinal cord and nerve roots, immediately relieving pressure. This interactive video provides an overview of the laminaplasty procedure for cervical spinal stenosis.

  椎板成形术用于治疗引起的疼痛的椎管狭窄。手术为脊髓和神经根创造更多的空间,迅速解除压迫。本视频简要介绍椎板成形术治疗颈椎管狭窄症。

Overview(概述)

  This surgical procedure crates more space for the spinal cord and nerve roots torelieve the painful pressure of spinal stenosis, a narrowing of the spinal canal that can result from arthritis.

  本手术为脊髓和神经根创造更多的空间,能缓解椎管狭窄压迫产生的疼痛。椎管狭窄是因关节炎等原因引起的椎管管径变小。

Preparation(准备)

  Anesthesia is administered, and the patient is placed in a face-down position. The surgeon s an incision on the back of the neck to access the cervical spine.

  麻醉后,患者取俯卧位。术者在颈后作切口,以显露颈椎。

Cutting the Vertebra(切开椎骨)

  On one side of the spine, the surgeon scores each lamina-the bony area that covers the spinal cord - to a vertical groove. On the other side, the surgeon carefully cuts all the way through each lamina.

  在脊柱的一侧,术者在每个椎板(覆盖在脊髓后方的骨性结构)上划痕,作一条垂直的骨槽,在对侧,将椎板完全切断。

Pressure Relieved(解除压迫)

  The grooves act as hinges, allowing the vertebrae to open like a door. This s more space in the spinal canal, immediately relieving pressure from the spinal cord and nerve roots. the surgeion examines the spinal canal and removes any bone spurs or other sources of compression.

  骨槽充当合页,使椎骨象门一样打开,这样可以为椎管创造更多的空间,立即解除了脊髓和神经根的压迫。术者检查椎管并去除骨赘和其它致压因素。

Wedges Placed (放置楔子)

  Ther surgeon inserts small wedges of bone graft material to hold the bone open. Screws and metal implants secure the vertbrae and the bone wedges.

  术者在开门侧放入楔形的小移植骨块,以保持骨板张开。用螺钉和接骨板固定椎骨和楔形骨块。

End of Procedure and Aftercare(手术结束及术后护理)

  The incision is closed and bandaged, and drains may be placed in the wound to prevent fluid buildup. A soft cervical collar may be used. Physical therapy may be needed.

  关闭并包扎切口。伤口内放置引流管防止积液。可能需要使用软颈托保护以及物理治疗。
