What does the medical abbreviation TIB mean?

Answer 1

The word TIB in medical terms means tibia, which is the larger of the two bones in the leg located between the knee and the ankle. The smaller bone in the same region of the leg is known as the fibula. An example of the use of these words is "Tib/Fib fracture", which is a fracture or crack in the two bones of the lower leg. I cannot verify that the definition above is the only definition of TIB as it relates to medical terminology.
You'll hear "tib" used as shorthand for "tibia," as in, "My mother had a tib/fib break."
