Summary
Early surgical resection of pediatric hemivertebrae significantly corrects congenital scoliosis and kyphoscoliosis, preventing severe spinal deformities. This double-approach hemivertebral resection offers sustained, safe correction in children.
Area of Science:
- Pediatric Orthopedics
- Spinal Surgery
- Congenital Deformities
Context:
- Congenital scoliosis and kyphoscoliosis often result from hemivertebrae.
- Deformities typically worsen in children with specific hemivertebra types and locations.
- Natural history indicates progressive spinal deformation without intervention.
Purpose:
- To evaluate the long-term outcomes of hemivertebral resection in pediatric patients.
- To assess the effectiveness of a double posterior and anterior approach with convex fusion.
- To determine if early surgical correction prevents severe spinal deformity progression.
Summary:
- Fifteen pediatric patients with progressive scoliosis/kyphoscoliosis due to hemivertebra underwent resection and fusion.
- Mean follow-up was 12.1 years, with significant improvements in segmental (70.5%) and total scoliosis (58.7%).
- Trunk imbalance improved from 31% to 9%, demonstrating sustained correction.
Impact:
- Hemivertebral resection via a double approach is an effective early treatment for congenital spinal deformities.
- The procedure safely corrects existing deformation and prevents future deterioration.
- Early intervention leads to sustained, positive outcomes in pediatric spinal deformity management.
