Correction of a Severe 90° Spinal Curve with Pedicle Subtraction Osteotomy

A patient presented with a severe 90-degree long spinal curve, resulting in significant spinal imbalance, postural deformity, and restricted mobility. Due to the severity and rigidity of the curve, advanced spinal deformity correction surgery was required to restore alignment and improve overall function.

Following comprehensive clinical assessment and detailed imaging studies, a personalized surgical plan was developed to achieve optimal correction and long-term spinal stability.

Understanding Severe Spinal Deformity

Severe spinal curves can progressively worsen over time, leading to postural imbalance, back pain, reduced flexibility, and limitations in daily activities. When the curve becomes rigid, conventional correction techniques may not provide adequate results.

Therefore, advanced osteotomy procedures are often necessary to achieve meaningful correction and restore spinal balance.

Surgical Procedure Performed

Pedicle Subtraction Osteotomy (PSO)

A pedicle subtraction osteotomy was performed to correct the severe deformity. This advanced technique involves removing a wedge-shaped portion of the vertebra, allowing the spine to be realigned into a more natural position.

As a result, significant correction of the rigid spinal curve was achieved.

Multilevel Facetectomy

Facetectomy was carried out at multiple levels to release stiff spinal segments and improve flexibility during correction.

Furthermore, this procedure helped facilitate safe and effective realignment of the spine.

Long Segment Fixation

After deformity correction, long segment fixation was performed using specialized spinal implants and rods. This stabilization technique helped maintain the corrected alignment and provided long-term support during healing.

Outcome

The surgery successfully corrected the severe 90-degree spinal curve and restored better spinal balance. Additionally, the procedure improved posture, stability, and overall functional outcomes while reducing the risk of further deformity progression.

Benefits of Surgical Correction

• Significant improvement in spinal alignment
• Better posture and body balance
• Enhanced spinal stability
• Improved mobility and daily function
• Prevention of curve progression
• Better long-term quality of life

Conclusion

This case demonstrates the successful correction of a severe 90-degree spinal deformity through pedicle subtraction osteotomy, multilevel facetectomy, and long segment fixation. By utilizing advanced spinal reconstruction techniques, excellent deformity correction and long-term spinal stability were achieved, helping the patient regain improved posture, function, and confidence.
