Relationship between developmental canal @entity850 and surgical results of anterior decompression and fusion in @entity1 with XXXX .

@entity1 @entity3799 @entity8939 @entity850 @entity528
BACKGROUND: Anterior cervical decompression and fusion (ACDF) has long been the preferred treatment for @entity3799 ( @entity3799 ). However, few studies have focused on surgical results of @entity3799 in @entity1 with developmental canal @entity850 ( @entity8939 ). The purpose of this study was to investigate @entity8939 as a comorbidity in @entity1 with @entity3799 and the correlation between surgical results and @entity8939 . METHODS: From January 1995 to December 2005, 122 @entity1 treated with ACDF for @entity3799 were enrolled in this retrospective study. Pavlov's ratio was used to evaluate cervical spinal canal size, with a value of   <   0.82 at least one level indicating @entity8939 . @entity1 were divided into two groups: those with @entity8939 preoperatively ( @entity8939 group, n   =   50 [41.0  %]) and those without @entity8939 ( @entity8939 , n   =   72). Clinical data and radiological parameters were compared between groups. RESULTS: There were no significant differences in preoperative and 2-year follow-up Japanese Orthopedic Association scores between groups. Both groups achieved satisfactory fusion rates ( @entity8939 , 92.0  %; non- @entity8939 , 93.0  %). @entity528 ( @entity528 ) was detected in 66.0  % of @entity1 in the @entity8939 group and in 43.0  % of @entity1 in the @entity8939 (p   =   0.01). However, there was no significant difference in the incidence of @entity528 requiring surgery between groups (p   =   0.20). DISCUSSION: @entity8939 is a common comorbidity in @entity1 with @entity3799 . The findings of this study have added knowledge on the correlation between @entity8939 and @entity528 after anterior fusion surgery. CONCLUSIONS: @entity8939 did not affect neurologic improvement postoperatively at short-term follow-up. Although @entity8939 increased the incidence of @entity528 after anterior fusion, it did not predict @entity528 requiring surgery. Therefore, @entity1 with @entity8939 must receive close follow-up.
