Abstract
Objective To explore the safety and efficacy of transpseudarthrosis osteotomy with interbody fusion in the treatment of Ankylosing Spondylitis (AS) patients with kyphotic spinal pseudarthrosis by a single posterior approach. Methods Twelve consecutive patients with spinal pseudarthrosis underwent transpseudarthrosis osteotomy and interbody fusion with a polyetheretherketone (PEEK) cage by a single posterior approach. The operative time, intraoperative blood loss, and complications were recorded. Radiographic and clinical results were assessed preoperatively and at the final follow-up. Results The average operative time was 201.9 min and the mean blood loss was 817.5 ml. The visual analogue scale (VAS) improved significantly from 6.7 preoperatively to 1.1 at the final follow-up. The average correction of the segmental kyphosis at the level of the pseudarthrosis was 22.3°. Bony fusion was achieved in all patients, and there was no obvious loss of correction at follow-up. Conclusion Transpseudarthrosis osteotomy at the level of the pseudarthrosis can be safely performed and surgical repair of pseudarthrosis with interbody fusion by a single posterior approach was feasible.
Highlights
Chronic inflammatory rheumatic disease affects the axial skeleton, causing characteristic inflammatory back pain, which leads to structural and functional impairments and a decrease in the quality of life [1]
The purpose of this study is to evaluate the effectiveness and safety of this technique
The human leukocyte antigen B27 (HLA-B27) test was positive in all patients
