Keywords:sacroiliac joint, lumbar spine, age-related change

【Purpose】
Many hip disease patients have coexisting limber spine disease. The concept of hip-spine syndrome was mentioned by Offierski and MacNab, which has been used to describe patients with coexisting hip arthrosis and lumbar spine disorders. Our previous study suggested that the age-related changes of the sacroiliac joint(SIJ)was related to that in the hip joint. The purpose of this study was to clarify the relationship in the age-related change of lumbar spine(LS)and SIJ using morphological analysis.
【Methods】
SIJ and LS(osteophyte of vertebral body and degenerative changes of zygapophysial joint)and periarticular osteophytes of six major joints in 42 modern male skeletons were quantitatively examined macroscopically. A corrected index of age-related change, which was the gap value(Gap), was calculated. Moreover, the degree of curvature in the anterior border line around the iliac auricular surface was calculated as a quantitative indicator, constriction ratio(CR). Some correlation coefficients were examined with Gaps and CR.
【Results】
The Gap in the major six joints was poorly correlated with that in the SIJ. Additionally, there was a weak positive correlation between the Gap in the left SIJ and LS. However, there was no positive correlation between Gap in the vertebral body and the mean value of CR of both sides.
【Discussion】
These results suggested that the age-related changes of SIJ is related to that of LS and that stability of SIJ might affect the extent of the mechanical stresses to the lumbar vertebral bodies. These findings may become the useful basic data to grasp pathological condition of the patient of joint disease of spine-pelvic-hip region.
