I'm not a good person to ask about surgery of LTN as in Melbourne Australia when I injured the LTN 20yrs ago-there wasn't the expertise here to even get any advice it's so rare. My understanding is surgery would only help for impingement/ obstruction.

My focus has been on functional restoration through clinical pilates, neurophysio /bobath technique, occupational therapy etc. Still pain remains a major issue for me and poor use of arm in raised position. However, I have hardly any winging after all my hard work and it makes a big difference to function at waist level. Don't be disheartened, my anatomy made me susceptible to developing bilateral TOS over time so your situation may have a much more optimistic outlook. booklover
