STUDY DESIGN: Retrospective case series. PURPOSE: To assess the effect of non-kyphotic aligned congenital C3-4 @entity8213 on the adjacent segment in 10 @entity1 . OVERVIEW OF LITERATURE: In the cervical spine, fusion disease at the adjacent motion segments may be a risk factor for potential neurological compromise and @entity204 . METHODS: Radiograms of 10 @entity1 13 to 69 years of age presenting with neck/shoulder discomfort or @entity158 with or without @entity130 history were examined. C3-4 @entity8213 was found incidentally in all @entity1 on routine examination radiographs of cervical spine. RESULTS: @entity1347 ( @entity1347 ) was not found in the three @entity1 younger than 39 years of age. Five of the 10 (50%) @entity1 , including a 67-year-old @entity1 , did not develop @entity4720 in any of the cervical mobile segments. Spondylosis was observed only in the caudal 1-2 mobile segments in the remaining five @entity1 . The youngest was a 40-year-old male who had @entity4720 in the two caudal mobile segments (C4-5 and @entity9509 ). Spondylosis was limited to the two close caudal mobile segments and was not in the cranial segments. Flaring of the lower part of synostotic vertebra associated with advanced narrowed degenerate disc was evident in five @entity1 . CONCLUSIONS: Mobile segment @entity4720 in the individuals with congenital monosegment C3-4 @entity8213 over age of 40 years may be a natural manifestation of aging and is not solely an adjacent segment disease directly and fully related with congenital C3-4 @entity8213 .
