颈椎椎管狭窄症及其手术治疗的研究

STUDY OF THE CERVICAL STENOSIS AND ITS OPERATIVE TREATMENT

本文报告75例颈椎椎管狭窄症及手术治疗情况。41例由于创伤诱发临床发病,占54.1%。狭窄的颈椎椎管可与包含的脊髓维持相对平衡而不发病,而创伤和退变是引起临床发病的主要原因。在某些条件下,颈椎椎管狭窄症,脊髓仅现局限或节段性压迫,因此,选择前路减压有直接切除致压物的作用,而广泛性多节段压迫则宜取后路减压。本组随访平均1.5年,优良率为84%(63/75)。

In order to study the pathogenesis and treatment of cervical stenosis,the authore repo-rted 75 cases with cervical stenosis that were operated.The onset of the diseases are causedby injury in 41 cases.34 cases have no obvious cause.From this study we found that thespinal cord can adapt,itself to the developmental narrow cervical spinal canal and there is noclinical manifestation in the person with developmental narrow of cervical spinal canal.Dege-neration and trauma are the main causes of the onset of the disease.In most circumstancesthe narrow cervical spinal canal only make partial segmental compression on the spinal cord.Therefore,anterior decompression can resect directly the material that compress the spinalcord.Extensive or multsegmental compression should be decompressed by posterior decompre-ssion or firstly by anterior and then by posterior decompression.The follow-up after ope-ration averaged 1.5 years.Excellent and good results were obtained in 84%(63/75)cases.
