Introduction. This study aimed to evaluate the effects of @entity1344 ( @entity1344 ) on clinical and radiographic outcomes, including spinal pelvic alignment. Method. Consecutive @entity1 who underwent 1- or 2-level @entity1344 for @entity4720 , mild @entity179 , or @entity179 were included. Clinical outcomes were evaluated by Visual Analogue Scale for back and @entity158 , @entity717 Index, and the Japanese Orthopedic Association scores. Radiographic outcomes were assessed by radiographs and computed tomography. Pelvic incidence and @entity1515 ( @entity1515 ) were also compared. Results. In 206 @entity1 with an average follow-up of 51.1    20.8 months, there were 87 screws (8.2%) in 42 @entity1 (20.4%) that were loose. All clinical outcomes improved at each time point after operation. @entity1 with loosened screws were 45 years older. Furthermore, there was a higher risk of @entity1349 in @entity1344 involving S1, and these @entity1 were more likely to have loosened screws if the @entity1515 failed to increase after the operation. Conclusions. The @entity1344 @entity1349 rate was overall 8.2% per screw and 20.4% per @entity1 at more than 4 years of follow-up. Older @entity1 , S1 involvement, and those @entity1 who failed to gain @entity1515 postoperatively were at higher risk of @entity1349 .
