Complications of Iliac Screw in Spinopelvic Fixation With Adult Spinal Deformity: Complications of Iliac Screw in Spinopelvic Fixation

ABSTRACT

STUDY DESIGN: Retrospective study. OBJECTIVES: To evaluate clinical & radiologic significance about complications of spinopelvic fixation with iliac screw in patients with adult spinal deformity. SUMMARY OF LITERATURE REVIEW Complications of iliac screw fixation in adult spinal deformity patients was obscure in spite of the good results of iliac screw fixation. MATERIALS AND METHODS: We analyzed 27 patients, followed over 1-year, with adult spinal deformity (lumbar degenerative kyphosis, degenerative lumbar scoliosis, flat back syndrome). The study was done for complications of iliac screw fixation by clinical and radiological evaluations. RESULTS: Post-operative iliac screw prominence were 15 cases (55.5%), iliac screw breakage was 1 case (3.7%), bursitis was 1 case (3.7%), sacroiliac joint pain were 5 cases (18.5%), halo sign around iliac screw were 23 cases (85.1%), and 3 cases (11.1%) were performed reoperation. There was no significance between halo sign and sacroiliac joint pain. CONCLUSIONS: Iliac screw fixation is a very useful operative method without severe complications on spinopelvic fixation. There are some complications of iliac screw fixation and iliac screw prominence is a most common problem, but few counterplan exits. So, further studies about reducing complication method, management protocols of iliac screw complication were needed.
