hello Linbin,
thanks a million for your advice. Joint limitation can be caused by scar tissue from stitches. Moreover, 2 pins are used for fracture in tibia. Now skin condition is good. May I discuss you if I have difficulties because I'm a junior physiotherapist. I need to read so many books. I also need examination to be skillful. Please share me your knowledge and experiences.
I wish you good health and great happiness.
yours sincerely, thiri
