Proposing the Retrosternal Angle as a Diagnostic Measure for Banana Sternum in Pectus Excavatum

In brief

This article introduces the retrosternal angle (RSA) as an objective diagnostic criterion for identifying banana sternum in pectus excavatum patients. The proposed measure addresses the current lack of standardized definition for this anteriorly convex sternal variant, which impacts surgical decision-making regarding bar placement during repair.

• Banana sternum (anteriorly convex sternum) in pectus excavatum complicates surgical repair and may require crossing bars during correction.
• Current definitions of banana sternum are subjective, creating inconsistency in surgical planning and decision-making.
• The retrosternal angle (RSA) is proposed as an objective, measurable criterion to standardize the diagnosis of banana sternum.
