The Pointer Sisters

The Pointer sisters are known for the fame of their song, “I’m So Excited,” during the disco era. But their story is more complicated than that. As their song lyric begins, “Tonight’s the night we’re gonna make it happen” their producer totally misunderstood the mood and dallied in flagrante delicto. The Sisters, as their surname implies, responded by kicking in unison and repeatedly striking the producer with their platforms and four-inch heels (de rigueur footwear for Disco) .

 Question: Which structure was likely injured by the heavy blows to the indicated area?

Postscript: The story is completely apocryphal, but could have happened, just saying.  The sisters were daughters of a church minister, but their other big hit was “Slow Hand”.
