- Brachy- (prefix)
- : Short. From the Greek brachys meaning short. The prefix "brachy-" appears in a number of medical terms including brachycephaly, brachydactyly, and brachytherapy: {{}}Brachycephaly is a short head, one that is short in diameter from front to back. Brachydactyly means short, stubby fingers and toes. Brachdactyly is a frequent feature of syndromes of congenital malformation (constellations of birth defects) including Down syndrome (trisomy 21). Brachytherapy is radiation treatment given by placing radioactive material directly in or near the target, which is often a tumor. The opposite of brachytherapy is teletherapy, treatment in which the radiation source is at a distance from the target.
