Hi.
I could not for three weeks post injury. On my first doctor’s visit post hospital discharge I asked about this and was given the OK to do so. She stated she put so much metal in me (2 plates and 14 screws) that the bones were not going to shift with sleeping.
However, I don’t know about you TPF details. Therefore, I would suggest you speaking to your doctor. TPFs are so individualistic that everyone and their needs are different. The treatment course for one can be different for the treatment course of another.
