i broken my wrist how can I still practice

Personally, I say relax and let your wrist heal completely.  Sometimes when trying to do to much when you have an injury only makes it worse and prolongs the time it takes to fully heal.

I too broke my wrist 40 years ago (I'm 60) and every year since when I start the golf season, it breaks again as soon as I hit a couple of drives and a few wedges on the first few holes.  It's a fracture in one of the carpal bones that couldn't be pinned like the rest of the carpal bones (of which there are a lot) at surgery.  A lot of Tylenol 3's and compression bandages until it eventually heals after playing 20 rounds (with a lot of pain) because it heals in a pronated position because the hand is now in that position more than in an off season supinated position where your hand/wrist isn't wrapped over and extended like in the grip at impact.

I'm a lefty and it's the left wrist and It swells and is very painful and it cannot be fixed by surgery, so each spring it breaks and I deal with it.  In the fall, it's fine because I go back to normal use once the clubs are retired for the season.

Don't know where the break is in your wrist, but hope you fully heal before you even begin thinking about hitting a ball or taking some turf.

A broken wrist will probably limit upper body work, so work on lower body/hip work. I had a similar situation a few years ago, I broke my foot. I worked on upper body and made huge progress after a few weeks!

I broke my wrist 11 weeks ago and I have just started to hit balls.  

I hit some balls one handed when my cast was on. The most important thing for you is to just let it heal. Don't force it - that'll only make things worse.

Sorry to hear you broke the wrist! Depending on which one you broke you can do one handed drills with low speed hits. This will improve your thing and transition.  Same can be done for putting with the left hand to make sure your take away is good.  With the right you can make sure it is going to your target.  

Last season early on my grandson broke his wrist. So as the old addage goes drive for show putt for dough! Well for six weeks everyday we hit the putting green from all distances and all breaks he's 15 now and one hell of a putter in the long run think it helped his game tremendously. He plays scrambles with my running buddies many a days just to get him putting for us. We still have him off the tees but his approach and putts are money. So you may consider that as a way to shave strokes.
