I broke my scaphoid bone about 6 weeks ago and am still in plaster. i am hoping it wont take as long as last year when i fractured the one on my other arm and it took 6 months to heal! my doctor has referred me to have a bone scan-got the letter yesterday. I have to have an injection and then go back 3 hours later. can anyone tell me what will happen and what results the doctors might be looking for. i am fed up with breaking my arms- have spent far too many summer months in plaster recently!
