ABSTRACT
[Objective]To summarize and evaluate the curative effect of anterior decompression approach by using cervical retractor systems to treat cervical spondylosis.[Method]From April 2002 to October 2004,68 cases were performed anterior undermined far-reaching decompression and fusion with autograft and titanium plate internal fixation by using removing disc merely at the single-level or separately at the multilevels employing CCR self-retractor and Caspar cervical retractor systems via interspinal approach.The cases were followed up,and serial roantgcnographic evaluations being applied.Then the height of involved intcrspinal space was measured preoperatively and after 12 months postoperatively,and the spinal function was evaluated in accordance with the standard of Japanese Orthopeadic Association(JOA),and then all results were compared statistically.[Result]51 of all cases were followed up,of which 50 were better,1 was improved,no one worsened.After 12 months postoperatively,roentgenographic appearance showed that the allograft healing and interbody fusion of all patients were achieved,and the reserving height of involved interspinal space and JOA evaluation postoperatively were significantly superior to both preoperatively.No complications such as cervical spinal cord injury,internal fixation unfastening,and hematoma turned up.[Conclusion]Anterior decompression approach by using cervical retractor systems to treat cervical spondylosis could better reserve the height of involved interspinal space,and improve the spinal function significantly.
