No just those, but knees, our vertebra as a supporting column is terrible, human hips - just ask any mother how well those are designed for childbirth. Do a search and you will find unnumerable examples of bad design in all animals. The reason is that evolution can only work with what is present, a condition that a supreme being would not (I would assume) be bound to.
I am no expert on biological body designs. It was Stephen C. Meyer who stated to the effect that in engineering all designs require a whole suite of parameters, and so tradeoffs and compromises are inevitable to create the best overall result.
