When bones are so close to each other then the mask would be about the bone itself.

Since you can segment these bones without too much difficulty using Grow from seeds effect with the [new masking feature](https://discourse.slicer.org/t/new-segment-editor-feature-masking-in-grow-from-seeds-effect/4978), a good approach could be to use “Segment registration” extension to register segments one by one.
