Oh those seem cool, maybe I will order some or sign up for a gym to try.

This is a good suggestion – they will take some strain off the wrists and increase range of motion per rep as an added bonus!

Again though, since we’re not just dealing with routine strain and pain, but actual broken bones that required medical attention, I do think it’s important that OP answers the questions in my original comment before we can give a hard recommendation (past the flexibility advice they asked for which I think is likely safe to suggest on).

We don’t know the extent of their injuries (from broken bones to any torn muscles and ligaments connected to the injuries) or where they are at in their recovery. If they’re still early in the recovery process, or if they recovered but were injured in a way that caused permanent fragility, they might need to wait longer and do lighter things to even build up to pushups or heavily modify the form by doing them on their knees.

I’m not knocking this though, I do think you have a fantastic suggestion here, I just want to make sure we don’t put it in OP’s head that they can grab a pair of these and start pumping out pushups. There are just too many talented athletes that thought they could forgo medical advice and ended up with permanent injuries that hindered them from ever improving or being as great as they were, as well as military members that tried to push through problems instead of seeing the doc and ended up on permanent profile as a result. If OP needs to start with low-weight assisted machines first (especially if they’re a high body weight) or low-resistance bands, etc., before pushing up their body weight on a pair of these, we need to know!
