Crushing Tramadol 150mg extended-release to bypass the time-release mechanism?

About a year ago, I was prescribed Tramadol 150mg extended-release for a vertebral fracture.

I have 1–2 pills left over and thought about taking them, as I’ve wanted to try them again for a while.

However, because they are extended-release, they aren't as strong and last a very long time. So my question is:

Can I crush the pills and just swallow them? Is 150mg safe, or is that already too much all at once? Is this a very dangerous thing to do, or is it okay?

Of course, I am aware that drug use, especially opioids, carries risks, but I mean specifically in this case. Unfortunately, I can't find much online regarding safer use dosages.
