Help! I’m Not Sure What Infrasternal Angle I Have!

Those pesky people who have infrasternal angles right in the middle. What do you call him?

Well in this case study, we talk about some tips and tricks for pinpointing the ISA that you are dealing.

We also dive into the following topics:

  • A couple quick tests to confirm the infrasternal angle
  • Why the xiphoid process is an unreliable reference point
  • How to prioritize treatments for someone who is compressed in all directions with asymmetries.
  • How shifting at different degrees of flexion changes the pelvic mechanics


  1. Hey Zac, can you please summarize the treatment plan in the debrief? Can you include the goal I believe was it left hip or shoulder ER with left foot forward etc. I got a little lost. Thanks.

  2. I’m pretty sure I’m a narrow, but I can fit my whole hand between my rib cage and ASIS on both sides. I do have a really long torso, but maybe there’s another explanation?

    1. Are you looking at the inferior thoracic aperture and top of iliac crest? Those are your markers.

    1. Could be wide? But hard to say without seeing. I trust the ISA first.
