Summary
Spinal osteotomies correct sagittal plane imbalances caused by deformities like kyphosis. Different osteotomy types offer varying degrees of correction for conditions such as degenerative imbalance and ankylosing spondylitis, improving patient outcomes.
Area of Science:
- Orthopedic Surgery
- Spinal Surgery
- Deformity Correction
Background:
- Spinal deformities, including thoracic kyphosis and loss of lumbar lordosis, cause sagittal plane imbalance.
- These deformities lead to significant functional and psychological impairment.
Purpose of the Study:
- To review various spinal osteotomy techniques for correcting sagittal plane imbalance.
- To highlight the indications and efficacy of different osteotomy procedures.
Main Methods:
- Review of spinal osteotomy techniques: Smith-Petersen osteotomy, pedicle subtraction osteotomy, cervical extension osteotomy, and vertebral column resection.
- Discussion of their degrees of correction and specific patient populations.
Main Results:
- Smith-Petersen osteotomy: ~10° correction per level, suitable for degenerative imbalance.
- Pedicle subtraction osteotomy: 30-40° correction per level, preferred for ankylosing spondylitis.
- Cervical extension osteotomy: Addresses cervical flexion deformities.
- Vertebral column resection: For severe, combined deformities.
Conclusions:
- Spinal osteotomies are effective in correcting diverse spinal deformities and sagittal plane imbalances.
- Neurologic complications are the most common, but patient satisfaction and functional outcomes are generally high.
