Glad to hear the surgery is over and successful. He should get the splint off and the stitches out on his next visit and go into the mechanical brace. My son was surprised that he started out at 120 degrees flexion and 30 extention...much more open then he expected it to be...he thought he would start out at 90 degrees..so he was alittle nervous when the dr set it and said your good to go and walked out. He made me get the dr to come back in and check it because he thought he made a mistake lol. He got used to it pretty quickly and becuase he started college about 4 weeks after surgery the doctor had him wear it all the time for 3 months and then had him wear it whenever he went out to class or practice just as a reminder that he still had limitations. He is now 3 weeks into his throwing program and throwing at 60ft. So far so good. No pain just a little soreness but dr says all normal stuff. Next hurdle will be throwing off the mound in late Feb. Good luck to your son with his rehab.
