1980 -- tonsils
1990 -- R shoulder used to dislocate 8-10 times a year and was pretty messed up by the time i finally agreed to have the arthroscopic surgery. no problems since. YAY!
7/2002 -- my car accident. had R tibia put back into my body, ankle joint cleaned out from having my ankle, tibia and fibula crushed, had an external fixator installed to hold my foot anatomically in place for three months while the tibia and fibula grew back, had a plate with 7 screws installed on my fibula, had multiple large lacerations on my R knee sewn up (i still have a torn meniscus that hasn't been dealt with) and had two long pins inserted into my R big toe to hold it anatomically in place (they were removed a month later in the doctor's office which was wild. i guess it could happen because the nerves required to lift my big toe took 9 months to grow back so i didn't experience a lot of pain as 2 6" or so pins were pulled out of my toe as i just sat there.)
10/2002 -- external fixator removed, ankle cleaned out again, bone graft on my R tibia and plate with 7 screws installed on my tibia (bone graft didn't take and i had a broken leg for 2 years while i used a bone stimulator to help the bone grow back).
there's always the potential for further surgeries as i continue to recover.
