Hi welcome to Healthcaremagic
Hi.... It takes around 90 to 100 days for a fracture
to get united to the normal form...The gap in the radius will be filled with the new bone called as callous, which will appear by 2 to 3 weeks and mature by 3 months.., there will be mild restriction of the movement of the elbow joint.. but after some time it will come back to normal.., after 1 of 2 years they will remove the implant..
Hope I have answered your question..
