Use of a novel maximum protrusion index to describe severe pectus carinatum

In brief

This study addresses the lack of standardized severity grading for pectus carinatum by introducing the Maximum Protrusion Index (MPI), a novel measurement that captures the point of maximal chest protrusion. Unlike the traditional Haller Index, which underestimates deformity, MPI aims to improve clinical decision-making and facilitate insurance approvals for treatment.

• Current Haller Index underestimates pectus carinatum severity by measuring to posterior sternum instead of maximal protrusion point.
• Lack of standardized PC severity grading creates barriers for clinical decision-making and insurance authorization.
• Maximum Protrusion Index (MPI) offers a more accurate measurement by targeting the point of greatest chest wall deformity.
• Novel MPI metric may improve objective assessment and treatment planning for severe pectus carinatum cases.
