Nope, that’s straight up bullshit. It was either osteotomized in surgery (cut out), or it was missing as a result of the injury. Both of these are semi common in fractures like that and for the fibula it’s fine. The fibula does not bear weight and really just helps add stability tonthe ankle joint, so as long as the lateral malleolus (the bottom of the fibula) is in tact there’s usually no problem.
