Oh dear - when will injuries to my grandsons stop. This time Joshua again. His leg has been hurting him for a while and today he had x rays and cat-scan. The bone graft (from a cadaver) has not taken and has caused an infection. He will be operated on at the end of March and a rod will be inserted in his knee down to his ankle. He will only be in overnight and must walk straight away. Hopefully this will be the last. Sarah.
