ABSTRACT
[Objective]To discuss the basic principles and methods of surgical protocols in treating multilevel cervical disc herniation.[Method]The surgical protocols patients underwent operation based on patient's changes in radiology.Protocols varied from anterior approach discectomy,partial corpectomy with bone grafting and plate fixing;titanium mesh+plate;titanium mesh+plate in major segment and decompression with trepan+cage in secondary segment;combined anterior and posterior surgical procedure.[Result]Totally 96 cases of cervical spondylosis in different types were observed.After average 32 months of follow-up,an overall excellent and good rate in 90% of the cases was obtained.[Conclusion]To choose the appropriate surgical protocol for different multilevel cervical disc herniaion or degenerative myelopathy patients,every treatment should rely on patient's symptoms and changes in radiology.We must check out which vertebra is major segment or secondary segment,generalized or localized,with or without developmental stenosis of cervical spinal canal.Most patients can achieve satisfied prognosis by anterior approach decompression with bone grafting and plate fixing.Intervertebral bone grafting and plate fixing is preferred to single level degenerative.Anterior decompression with approach discectomy,partial corpectomy with bone grafting and plate fixing is preferred to 2 or 3 level degenerative.Combined anterior and posterior surgical procedure is the best method to treat generalized degenerative or obvious stenosis of cervical spinal canal,and continuous type OPLL.In conclusion,the key to excellent prognosis of cervical spondylosis is choosing the right operation for the right patient.
