OBJECTIVE: To point out our selection criteria for spinopelvic fixation in degenerative spine disease in adults. METHODS: Between 2005 and 2008, 25 patients who underwent lumbosacral spine surgery with spinopelvic fixation with iliac screws were analysed. Selection criteria: 1) Severe deformities associated with pelvic imbalance. 2) Multilevel fusion associated with degenerative disease of the first mobile space. 3) Revision surgeries: Kyphoscoliosis or high-grade spondylolisthesis. We assessed age, sex, pre and postoperative Oswestry Score and complications. RESULTS: Age was 55 to 75 years (mean 67.8). Two patients (8%) were male and 23 (92%) female. Mean follow-up: 2.5 years. Preoperative Oswestry Score : 67.44%; postoperative: 9.76%. Three complications were found: one acute infection, one pseudoarthrosis, and loosening of iliac screws in one patient. CONCLUSION: The spinopelvic fixation with iliac screws is a simple technique which allows an optimal distal anchorage in lumbosacral fusions for revision surgeries and complex deformities.
