Lee had an undisplaced Colles' fracture, the radius and ulna at the wrist. He had no surgery, hence no pins or screws. He was in a cast for, I believe, six weeks: first a long one for four weeks, then a short (below elbow) cast. Injuries like this are common and usually heal without any problems. You're right that all fractures are different, and some wrist fractures can be devastating, but that isn't the case here. Still, it typically takes six to nine months to really get back to normal from an injury like this, and even then there can be complications like recurrent tendonitis and carpal tunnel syndrome. I imagine he'll be fine by spring training, though he might require a little more time off than he used to get before the injury. I believe Jeff Kent had a similar injury about five years ago. He's done fine, though I heard he had to have a small procedure on the wrist when he was in Houston. Hope this helps.
