Summary
Cervical osteotomy with internal fixation is a stable technique for ankylosing spondylitis. Transcranial electrical stimulated motor evoked potential (TES-MEP) monitoring aids in preventing permanent spinal cord damage during surgery.
Area of Science:
- Spine surgery
- Neuromonitoring
- Orthopedics
Background:
- Cervical kyphosis in ankylosing spondylitis often requires surgical intervention.
- Cervical osteotomy is a complex procedure with potential neurological risks.
Purpose of the Study:
- To evaluate the efficacy and safety of C7 osteotomy with internal fixation.
- To assess the role of transcranial electrical stimulated motor evoked potential (TES-MEP) monitoring in cervical osteotomy.
Main Methods:
- Retrospective review of 16 patients undergoing C7 osteotomy with internal fixation.
- Comparison of surgical outcomes between sitting (group S) and prone (group P) positions.
- Utilized TES-MEP for intraoperative neuromonitoring.
Main Results:
- All patients achieved solid bone consolidation without loss of correction.
- The prone position allowed for more stable fixation and simplified post-operative immobilization.
- TES-MEP monitoring identified neurological events, enabling timely interventions in most cases.
Conclusions:
- C7 osteotomy with internal fixation is a reliable and stable surgical technique.
- Prone positioning optimizes fixation and allows for less restrictive post-operative bracing.
- TES-MEP is a valuable neuromonitoring tool for preventing permanent spinal cord injury during cervical osteotomy.
