Hi Son,
It is a great case to follow up,
I agree the defect in the interosseous membrane has a persisting defect and the surrounding muscle now looks much better as the surrounding haematoma / interstitial b blood / oedema has resolved.
I still think the muscle immediately adjacent to the tibia has an abnormal appearance, but it is much improved from the last scan.
I doubt the defect in the interosseous membrane will ever completely recover, I suspect a layer of fibrosis will develop across the defect.
Great follow up!
This case has made me much more focussed on assessing the interosseous membrane, something I don’t think I have considered enough in the past.
