[Radiological factors influencing pulmonary function test in severe spinal deformity]

Area of Science:

• Orthopedics
• Pulmonology
• Radiology

Background:

• Severe spinal deformities significantly impact patient health.
• Pulmonary function can be compromised in individuals with spinal deformities.

Purpose of the Study:

• To characterize pulmonary dysfunction patterns in severe spinal deformity.
• To identify radiological predictors of pulmonary function impairment.

Main Methods:

• Retrospective analysis of 66 patients with severe spinal deformity.
• Preoperative pulmonary function testing (PFTs) and radiographic assessments.
• Correlation and regression analyses to link deformity measurements with PFT results.

Main Results:

• 86% of patients exhibited impaired PFTs, with over half showing moderate to severe dysfunction.
• A restrictive pulmonary function pattern was common.
• Major curve magnitude and number of involved thoracic vertebrae significantly correlated with pulmonary function.

Conclusions:

• Preoperative pulmonary dysfunction is prevalent in severe spinal deformity.
• Spinal curve magnitude and thoracic vertebral involvement are primary risk factors for pulmonary impairment.
