The story of the word

ἰσχίον named the hip joint. The ischium is the part of the pelvis that takes your weight when you sit, and its thickened tuberosity is what trainers call the sit bone. Sciatica is the same Greek word taken through Latin with the first vowel worn away: ἰσχιαδικός, of the hip, became sciaticus, and the nerve that runs down the back of the leg still carries the hip's name.
