Sagittal Spine Balance in Patients With Chest Wall Deformity

Assessment of sagittal spine balance in patients operated on for anterior chest wall funnel deformity.

Inclusion criteria

age 10-18 idiopathic funnel chest Haller index above 3.2

Exclusion criteria

Previous surgery within the chest and spine regions Anterior chest wall deformities caused by other disease syndromes (e.g. Marfan syndrome, Ehlers-Danlos syndrome) Haller index below 3.2

Study protocol:

• Computed tomography of the chest.
• Before the procedure, x-ray of the entire spine in a standing position, including the entire chest, pelvis and hip joints in the anterior and lateral projections (technical parameters will be provided separately).
• Six months after the procedure, x-ray of the entire spine in a standing position, including the entire chest, pelvis and hip joints in the anterior and lateral projections (technical parameters will be provided separately).

The following are measured:

• Haller index
• Asymmetry index
• Assessment of the Cobb angle in the case of disorders in the frontal plane - before and 6 months after the procedure
• Assessment of the sagittal balance of the spine (details in a separate document) - before and 6 months after the procedure

We assess:

• Deviations in sagittal balance in patients before the procedure by X-ray.
• Change in the distance between the sternum and the anterior part of the nearest vertebral body after virtual reproduction of the correct sagittal balance by AI.
• Change in the distance between the sternum and the anterior part of the nearest vertebral body 6 months after the Nuss procedure by X-ray.

Objective:

• Does the funnel deformity affects the sagittal balance of the spine?
• Does restoring the correct balance reduce the distance between the retracted sternum and the spine (AI)?
• Does the sagittal balance of the spine change 6 months after surgical treatment?

Inclusion criteria

• idiopathic funnel chest
• Haller index above 3.2

Exclusion criteria

• Previous surgery within the chest and spine regions
• Anterior chest wall deformities caused by other disease syndromes (e.g. Marfan syndrome, Ehlers-Danlos syndrome)
• Haller index below 3.2
