Progress on laminoplasty in spinal canal disease / 中国骨伤

ABSTRACT

Surgery is the preferred method for the treatment of spinal canal disease, surgical method involves laminectomy and laminoplasty. The ideal spinal surgery not only should fully expose the spinal canal, completely resect the occupied position and remove the spinal cord compression, but also should maintain the stability of spinal biomechanics. Because of the different realization of clinician to safeguard and rebuild the spinal stabilization during opertion of spinal canal disease, and choice of surgical method and how to maintain the stability of spine biomechanics has become a hot of research in this field. Many scholars have studied it in order to reduce the influence of laminectomy on the spinal stability. Laminoplasty can directly relieve the nerve roots compression caused by increasing or reconstruction of vertebral canal volume, and allow the migration of spinal cord to dorsum and depart from disc and vertebral body. Laminoplasty not only can fully expose and decompress during operative, but also may prevent the postoperative spinal instability. In addition to these condition of extensive disease, severe bone destruction or combined with osteoporosis, the laminoplasty is the most ideal method for single spinal canal disease in theoretically.
