title: Radiological ageing process in the cervical spine of Nigerian women.
abstract: The study was designed to determine the age of commencement of ageing process in Nigerian women Four hundred (400) consecutive women requesting for cervical spine radiographs where recruited for this study. A study chart was made showing different variables like osteoarthrosis, detached osteophytes, postural ulterations and disk degenerations in a four year period from 1st January, 1993 to 31st December, 1996 the modified Kellgren and Lawrence grading system was used to assess radiographic changes. The highest rate of osteoarthrosis (31.13%) was found in the fifth decade. Incidence of postural alterations of the cervical spine rose sharply in the 5th and 6th decades of life. Grade 2 osteoarthrosis (Kellgren and Lawrence) was commonest (61.3%); Grades 3 and 4 had the lowest incidence (3.45%). Disc degeneration was commonest in the 5th; the most involved disc was C5/C6 and the least involved was C2/C3. It is concluded that the ageing process in the Nigerian women commences in the fourth decade of life, and apparently shows no difference with caucasian women.
