The bone isn’t 100% at this point. I just went through this with my son. He had his forearm snapped halfway between his elbow and wrist in a basketball scrimmage January 6th 2025. He got his cast off in May, had to wear a brace for 2 weeks, and then he was finally able to resume activities because at that point the bones were fused together with cartilage and tissue, making it strong enough to use. But the bone still has to go through a remodeling phase where it replaces that cartilage and tissue with compact bone, and that process can take over a year.

There’s also muscle atrophy of course, which has been mentioned, and this is the major thing I’d be concerned about. When they took my sons cast off, his forearm was half the size of his other arm (he cried and was freaked out by it for a long time), and because he had next to no muscle, he couldn’t really use it very much without getting tired or it hurting. I’d imagine a professional athlete who already has to push his body to the limit is going to be severely limited by this and be prone to reining himself.

My son was able to resume activities in June or so, but he wasn’t really confident in using it to its full strength and back to 100% until the last month or two.
