This item was discussed during the TUG meeting in Antwerp. See https://conf.spaces.snomed.org/wiki/spaces/TRANSLATIONUSERGROUP/pages/174161988/2025-10-21+-+Translation+User+Group+Meeting+Antwerp.
There are two possibilities for further discussions:
1 Keep ‘digit of hand’ as a parent concept and finger 1, finger 2, finger 3, finger 4 and thumb as direct children, i.e. without ‘finger’ as an intermediate concept for finger 1, 2, 3 and 4. This will match how anatomy of this area is conceptualized in member countries present in the Translation User Group. However, this will have consequences for the ontology which are not analyzed.
2 Keep the current anatomy model in the body structure hierarchy, but introduce ‘digit of hand’ as parent of ‘finger’ and ‘thumb’ consistently in other hierarchies. This pragmatic option will probably have less consequences, but not eliminate the problem entirely.
