AI Article Synopsis
- This study investigates the connection between shoulder function and MRI findings in children with neonatal brachial plexus palsy (NBPP).
- Researchers assessed shoulder strength and muscle condition in 16 children, focusing on two specific muscles and the shape of the glenoid.
- Results showed that greater fatty infiltration in the subscapularis muscle was associated with decreased muscle thickness and poorer shoulder function, suggesting the need for detailed muscle evaluation in MRI assessments for NBPP patients.
Article Abstract
Purpose: The relationship between functional shoulder deficits in children with neonatal brachial plexus palsy (NBPP) and magnetic resonance imaging (MRI) shoulder abnormalities was evaluated.
Methods: Shoulder function was assessed in 16 children (mean age: 5.8 years; range: 3-12 years) with NBPP based on shoulder rotator muscle strength, as measured using an isokinetic dynamometer and the modified Mallet score. The thickness and fatty infiltration of the subscapularis and infraspinatus muscles, and the morphology of the glenoid on MRI, were also determined.
Results: The highest subscapularis fatty infiltration subgroup of NBPP patients promoted the highest alteration muscle thickness and modified Mallet score.
Conclusions: In NBPP children, subscapularis impairments play a major role in the functional limitations. This study of pediatric NBPP patients highlighted the value of adding an examination of the muscles to routine MRI assessment of bone parameters in the shoulders of NBPP children.
