Treatment of Andersson lesion-complicating ankylosing spondylitis via transpedicular subtraction and disc resection osteotomy, a retrospective study

摘要

Andersson lesion (AL) can occur in patients with ankylosing spondylitis (AS). Surgical instrumentation and fusion is considered the principle management in symptomatic AL that fails to resolve from a conservative treatment. However, there is significant controversy over the ideal management. The purpose of this study is to introduce our experience and explore the efficacy and feasibility of transpedicular subtraction and disc resection osteotomy technique for patients with AL-complicating AS.
