lacinate ligament...question

Posted by Terry D. on 6/20/03 at 09:55 (122430)

This might sound like a dumb question...but I've not had it answered.
When the posterier nerve is released by cutting the lacinate ligament what now holds the nerve, tendon, and ligament in place so it doesn't 'bowstring' etc.? And if all 4 tunnels are released what keeps these nerves in place?
Thanks for any insight.

Terry,

Very good question.

I don't know the answer, but I do know that I've been one or two comments in the literature about problems resulting from tendons that moved out of place after TTS surgery.

Terry:

Only the 'roof' of the canal that holds the nerve in place is being cut, so the nerve still has a place to lie. The nerve is not under enough tension to bowstring.
