Mary Cassatt was one of the three great female impressionists along with Berthe Morisot and Marie Bracquemond. Most of Cassatt's paintings focused on domestic scenes of mothers, infants, and children, almost exclusively female. Her paintings depicted children with common pediatric orthopaedic conditions like tibial torsion, metatarsus adductus, and asymmetric medial thigh skin folds. It was during this same time that clinical scientists were establishing the scientific foundations of our modern understanding of these pediatric orthopaedic conditions.
