椎管重建避免了传统手术的弊端,是目前椎管内肿瘤切除术中维持脊柱稳定性及保持椎管完整性的主要手段。椎管重建主要包括全椎板切除重建、半椎板切除重建及部分半椎板切除重建等方式,椎管重建的理念强调术中要保留椎弓根、关节突关节、韧带、棘突、椎板等维持脊柱稳定的后部结构,术后要保持椎管的完整性,避免硬脊膜周围的粘连。研究表明:经一侧半椎板入路半椎板或部分半椎板切除后椎管重建,能够在不影响切除肿瘤的情况下,将损伤降低到最小限度。椎管重建的不断发展为处理椎管内肿瘤提供了可靠的保障。
Spinal canal reconstruction to avoid the disadvantages of traditional surgery is the main means of maintaining spinal stability and maintain spinal integrity during resection of spinal canal. Spinal reconstruction includes laminectomy and reconstruction, resection and reconstruction of the half-laminectomy and partial resection and reconstruction of the half-laminectomy. The concept of spinal canal reconstruction emphasizes that the pedicle, the facet joint, the ligament, the spinous process and the vertebral column Plate and other structures to maintain the stability of the spine after surgery to maintain the integrity of the spinal canal, to avoid adhesions around the dura. Studies have shown that: one half of the laminectomy half or a half of the laminectomy after spinal canal reconstruction, can not affect the excision of the tumor, the damage will be reduced to a minimum. The continuous development of spinal canal reconstruction provides a reliable guarantee for the treatment of spinal canal tumors.
