Multiplanar Humeral Shape Changes from Infancy to Adulthood in Patients with Birth-Related Brachial Plexus Palsy: A Cross-Sectional Analysis.

Background: Birth-related brachial plexus palsy (BRBPP), occurring in up to 1.7% of live births, may have drastic effects on quality of life for those failing to recover shortly after birth. As humeral shape changes correlate with function in older children with BRBPP, the purpose of this study is to evaluate the temporal patterns of humeral shape pathology resulting from unilateral BRBPP spanning the arc from infancy to adulthood, strengthening our knowledge as a basis for clinical intervention.

Humeral Development Throughout the Arc of Childhood-A 3D MRI Study.

A quantitative understanding of humeral morphology through the arc of pediatric development is crucial in optimizing the treatment of pediatric shoulder-related orthopedic disorders and athletic overuse injuries. However, data regarding modern normative humeral development are not available. Thus, the aim of this study is to derive biomechanically relevant humeral size and shape measures from a pediatric cohort spanning infancy to adulthood (age 0.
