Neither Carinatum nor Excavatum: Insights Regarding the Novel Postprematurity Thoracic Dysplasia and Traditional Harrison Grooves

In recent years, a new chest wall malformation (CWM), the postprematurity thoracic dysplasia (PPTD), was reported. It was characterized as an inward deviation of the anterior tips of the 6th ribs and a personal history of prematurity and respiratory distress. At the moment, PPTD's prevalence and etiology are yet to be defined. Thus, we aimed to explore and identify patients with a compatible morphology within a large cohort of patients with CWM.
