STUDY DESIGN: Cross-sectional study. OBJECTIVE: To investigate the relation between lumbosacropelvic morphology and the presence and degree of @entity528 . SUMMARY OF BACKGROUND DATA: @entity571 of the facet joints is one of the most common degenerative changes in the spine. It is considered to be formed secondary to repetitive stress or @entity130 and @entity85 with secondary overload. The cause(s) of facet joints @entity571 , however, have not been clearly identified. METHODS: Abdominal computed tomography (CT) images of 723 @entity1 which were taken between the years 2010 and 2014 were evaluated retrospectively. @entity1 with prior lumbar spinal surgery, serious @entity154 on CT, @entity10145 , severe @entity1635 , were excluded from the study. To eliminate the age- and sex-related differences in spinopelvic morphology, a study group was formed of the remaining subjects by including @entity1 from a specific age group (30-35 yr) and same sex (females). For each @entity1 the presence and grade of @entity528 was investigated. In addition, pelvic incidence (PI), sacral slope and the angles of L1-L5 lumbar @entity1515 , sacral table, L5 vertebra posterior, and sacral @entity1513 were measured for each @entity1 . RESULTS: Sacral slope, sacral @entity1513 , and L1-L5 lumbar @entity1515 angle were significantly higher in @entity1 with osteoarthritic compared with normal subjects (P = 0.015, P = 0.018, P = 0.016). L5 vertebra posterior and sacral table angle were found to be significantly lower in @entity1 with osteoarthritic than in normal subjects (P = 0.019, P = 0.007). The degree of @entity528 was noticed to increase parallel to the decrease in the sacral table angle and L5 vertebra posterior angle, and to the increase in the L1-L5 lumbar @entity1515 , PI, and sacral slope. CONCLUSION: A close relation exists between the presence and degree of @entity528 and lumbosacral pelvic morphology. Prevalence and degree of the degeneration in facet joint increases as the angle of sacral slope, L1-L5 lumbar @entity1515 , and PI increases or the angle of sacral table and L5 vertebra posterior decreases. LEVEL OF EVIDENCE: 4.
