Summary
Significant advancements in understanding and treating sagittal plane deformity have occurred. Proper surgical planning and pelvic role understanding are crucial for maintaining sagittal balance during lumbar fusion.
Area of Science:
- Spine surgery
- Orthopedics
- Biomechanical analysis
Background:
- The past decade has seen major progress in comprehending and managing sagittal plane deformities.
- Normative values for sagittal plane geometry and the pelvis's role have been clarified through recent studies.
Purpose of the Study:
- To review current understanding of sagittal plane deformity.
- To highlight the importance of surgical planning in lumbar fusion for maintaining sagittal balance.
- To describe osteotomy techniques for restoring sagittal alignment.
Main Methods:
- Review of recent studies on sagittal plane geometry and pelvic contribution.
- Analysis of surgical techniques for lumbar degenerative disease fusion.
- Description of osteotomy methods for sagittal alignment restoration.
Main Results:
- Improved understanding of normative sagittal plane values.
- Recognition of the pelvis's critical role in sagittal balance.
- Established importance of surgical planning and patient positioning in lumbar fusion.
- Detailed description of osteotomy techniques for correction.
Conclusions:
- Sagittal balance is paramount in lumbar fusion for degenerative disease.
- Osteotomies are effective for restoring sagittal alignment when necessary.
- Continued research refines the understanding and treatment of sagittal plane deformities.
