～にけがをする versus ～をけがする
"私は左手にけがをした" means that your left hand was injured. "私は左手をけがした" means you
injured your left hand. Similar meaning, left hand is injured in both, but the
focus of blame is different. Both are correct.

They are both correct.

As you can see in [this J-J dictionary
entry](https://kotobank.jp/word/%E6%80%AA%E6%88%91-489585#E5.A4.A7.E8.BE.9E.E6.9E.97.20.E7.AC.AC.E4.B8.89.E7.89.88),
[怪我]{けが} can be _a noun_ and _a する-verb_ , so you can say for example:

> 「彼は事故で腕 **に** 怪我 **を** した。」(← 怪我 is a noun)  
>  「彼は事故で腕 **を** 怪我した。」(← 怪我 is a suru-verb)  
>  "He injured his arm in an/the accident."

The only difference that I can feel is... the latter sounds just a little bit
more casual/less formal than the former.
