💡 AI Summary & Key Takeaways
– Hyperkyphosis exceeding 50–60 degrees often stems from Scheuermann’s disease, osteoporosis, or structural wedge deformities.
– Corrective spine osteotomies restore global sagittal alignment and alleviate thoracic pain.
– Advanced rigid fixation provides immediate structural stability.
– Corrective spine osteotomies restore global sagittal alignment and alleviate thoracic pain.
– Advanced rigid fixation provides immediate structural stability.
Clinical Overview of Thoracic Hyperkyphosis
Normal thoracic kyphosis ranges between 20° and 40°. When sagittal curvature exceeds 50°–60°, it is classified as hyperkyphosis, commonly triggered by Scheuermann’s disease, congenital malformations, or post-traumatic collapse.
Surgical Correction and Sagittal Alignment
Surgical management focuses on restoring harmonious global sagittal balance and relieving spinal cord tension:
- Ponte and Smith-Petersen Osteotomies: Facilitating multi-level posterior column shortening to achieve gradual, safe extension.
- Dual-Rod Rigid Fixation: Maintaining anatomical thoracic contouring while allowing rapid fusion.
