Pedicle Subtraction Osteotomy & Vertebral Column Resection for Severe Kyphoscoliosis (PSO/VCR)

National Science & Tech Award

国家卫健委四级骨科手术临床技术规范准入 · National Science & Tech Progress Award / Severe Rigid Kyphoscoliosis Realignment

For rigid kyphoscoliosis (Cobb >100°), posterior vertebral column resection (PVCR) and pedicle subtraction osteotomy (PSO) deliver >72% correction via a single posterior approach with multimodal neuromonitoring, keeping paraplegia risk below 0.5%.

Severe Scoliosis Cobb Angle Correction Rate

72.8% - 78.4%

Control: 仅 45.0% - 55.0% (并发症率超45%)

Evidence Level

Chinese Expert Consensus on Osteotomies for Severe Rigid Spinal Deformities (2024)

Spine & European Spine Journal 500+ 例多中心长期随访注册队列

Treatment Course

5-7 天 (全脊柱 EOS 站立位成像 + 肺功能综合评定与 Halo 牵引预适应)

One-time definitive spinal reconstruction; wear custom brace for 3 months; lifelong upright alignment.

Global Advantage

Direct Billing Available

Mechanism of Action (MOA)

Posterior VCR 3D De-rotation & Sagittal Alignment Pathway

1

Single-Stage 360° PVCR: Complete circumferential vertebral column resection through a single posterior incision without thoracotomy.

2

3D Multi-Axial De-rotation: Multi-rod construct achieves >75% Cobb correction, restoring true sagittal vertical balance.

3

Real-Time Multimodal Neuromonitoring: Synchronous MEP/SEP monitoring keeps permanent neurological deficits below 0.5%.

Patient Profile & Indications

Quantified entry criteria and stages for foreign referral

Severe rigid idiopathic or congenital kyphoscoliosis (Cobb angle >90°-130°).

Severe angular kyphosis post-ankylosing spondylitis or tuberculosis (>90°).

Severe post-fusion pseudoarthrosis or severe junctional kyphosis revision.

Strict Exclusion Red Lines

• ✕Irreversible complete spinal cord transection with complete paraplegia.
• ✕End-stage cardiopulmonary failure unable to tolerate prone anesthesia.
• ✕Active uncontrolled systemic sepsis or acute active tuberculosis.
