1: The chart is readable because even though it has an early ascendant it's in virgo which rules health consciousness and worrying.
2: Her wrist is not broken. She is ruled by Jupiter and Neptune, and her wrists are ruled by the Sun and Mercury, and her health is ruled bythe Moon, and Mercury. There are no applying aspects betwen any of these planets. This shows that her wrist is not broken
BTW im not that experienced at horary astrology so can anyone else confirm my conclusion?
