What is meant by collapsed wrist?this ___/ or this -------\
When your wrist is collapsed it is like rope at an angle scraping against an edge of a table. When your wrist is in the correct position the tendons or "ropes" are straight and dont scrape against the bone. Just having your wrists collapsed does not cause the problem. Your fingers have to be moving as well. The finger movement causes the tendons to scrape and cause inflamation. The inflamation causes swelling which makes the hole that the tendons and arteries go through become tight.
