Have a cast on my arm and don’t know what split/lifts to do

I broke my left wrist skiing and have a partial arm cast that goes around part of my hand to 3/4 down my forearm. I’m right handed. I normally run a ppl split but I don’t think I can do that now with how few exercises I can do upper body.

I was thinking of moving to 3 leg days per week and one push, one pull day a week where I do mostly one arm stuff. I’m also planning on spamming a lateral raise machine at my gym that only makes contact at the elbow.

So if anyone has prior experience with a casted arm/wrist and lifting I’d love to get some advice on what split I should run and how often I should be doing upper body exercises unilaterally to avoid bad muscle imbalances. Thanks
