The 6 week period following surgery is a time for healing and caution. My doctor did recommend using traction AFTER this period was over. I had excision and grafting and the traction was to help keep the graft tissue stretched and plicable as it was "settling in". My doctor particularly wanted me to use traction during months 3 through 6 post surgery. I'm quite pleased with the results 2 years later.

Anybody else tried using it after the surgery? The idea is stretching the scar tissue thus maximizing the length expansion capacity of LGX.
