Spinal deformities and lung function in adults with osteogenesis imperfecta

Area of Science:

• Pulmonary Medicine
• Orthopedics
• Genetics

Background:

• Limited research exists on spinal deformities and lung function in adults with osteogenesis imperfecta (OI).
• Spinal cord deformities can significantly affect respiratory assessments in OI patients.

Purpose of the Study:

• To determine the prevalence and severity of spinal deformities in adults with OI.
• To evaluate lung function in this population.
• To investigate the correlation between spinal deformities and lung function compromise.

Main Methods:

• Radiographic assessment of spinal deformities using a semi-quantitative (SQ) approach and calculating the Spinal Deformity Index (SDI).
• Spirometry to assess lung function, utilizing both measured and arm-span height for predictions.
• Analysis of correlations between spirometry variables and spinal deformity metrics.

Main Results:

• 67% of adults with OI exhibited vertebral deformities, predominantly in the mid-thoracic region.
• Scoliosis was present in 46% of patients.
• Significant negative correlations were found between spirometry results and spinal deformities, highlighting the impact of these conditions on lung function.

Conclusions:

• Osteogenesis imperfecta (OI) patients commonly present with spinal deformities that affect both body height and lung function.
• Lung function testing in OI patients requires correction for reduced body height using arm-span measurements.
• Spirometry evaluation is recommended for OI patients when vertebral deformities are suspected.
