From the pic posted, Florence Welch sustained a fracture of the head of her third metatarsal which is the central long bone in the forefoot. When there is little displacement of shifting of bone as in this case, surgery is not necessary. Keeping off of the foot allows bone to heal without further injury or movement and shifting. Patients routinely ask in situations like this how long they have to be off the foot and off work. Typical bone healing takes 6-8 weeks. The key is staying off the foot so return to work is dependent on the physical demands of the job. In this case, to the joy of her fans she will continue to perform, but in a less active way. We wish her a speedy recovery.
