Summary description of the study

Following an ankle surgery, a surgical procedure is often performed where the osteosynthesis material (plates/screws) is removed, in order to reduce discomfort or pain related to the osteosynthesis material. Our research project aims to study whether the effectiveness presented by this surgical procedure is superior to conservative treatment, that is, without surgery. To this end, we will recruit patients who have recently undergone surgery for an ankle fracture. They will then be randomly assigned to one of two groups, either in the group where the material (plate/screws) will be removed, or in the group where the material will be kept in place. Patients will need to complete two questionnaires at the beginning and at the end of the study (at 6 months) and we will then compare the results.
