Brachial Plexus Birth Palsy-Glenohumeral Dysplasia Following Neonatal Brachial Plexus Palsy: Presentation and Predictive Features During Infancy

Glenohumeral Dysplasia Following Neonatal Brachial Plexus Palsy: Presentation and Predictive Features During Infancy

Pdf Summary

Glenohumeral dysplasia (GHD) often occurs in infants with neonatal brachial plexus palsy (NBPP) and can affect the functional outcome of nerve and musculoskeletal reconstruction. Researchers conducted a study to evaluate the presence and severity of GHD in infants undergoing surgical exploration for NBPP and to identify potential predictive factors for early maladaptive shoulder morphology. The study included 19 infants who underwent surgery and had a magnetic resonance imaging (MRI) scan. Of these infants, 74% had GHD of Waters class 2 or higher. The severity of GHD was associated with increasing age and factors related to muscular imbalance. Specifically, less severe GHD was associated with more severe palsies and greater total shoulder active range of motion and pectoralis major muscle mass. The study also found that patients with Erb palsy tended to have worse GHD compared to those with complete plexus palsy. The findings of this study underscore the importance of early screening and assessment of GHD in infants with NBPP in order to optimize treatment outcomes.
