59F with suspected PTT tear

This is an anatomy question.  Is the segment indicated by the white arrow an accessory slip of the PTT or the plantar navicular-medial cuniform capsule?  The red arrow indicates the main insertion onto the medial pole navicular. References mention accessory slips inserting onto the cuneiforms and 2nd-4th MT bases.  I'm not clear if that includes the base of the medial cuneiform.  Do you know?

58F Chronic Refractory Hip Pain

There is G Minimus Tendinosis and High grade insertional tear with contiguous partial tear of the Vastus Lateralis. This looks similar to the contiguous delaminating type tear we see in athletic pubalgia at the Rectus Abdominis-Adductor Longus aponeurosis.  Is there a common aponeurosis in this location?  I've seen this many times.
