Overview
Brief Summary
Patients who underwent operative treatment of an ankle fracture with or without following removal of the osteosynthetic material are examined by a specific ankle provocation test, a questionnaire and X-Rays to evaluate the clinical, functional and radiological outcome compared to a healthy control group
Detailed Description
The study includes all patients operated from 09.12.2012 to 31.12.2020. Patients will undergo an X-Ray at least two years after primary surgery or at least one year after removal of the osteosynthetic material. The patients operated from 09.12.2012 to date are therefore a retrospective cohort, the patients from to date until 31.12.2020 a prospective cohort. This method is used to achieve the highest possible number of patients in a define period of time with no alteration of surgical technique. All patients in the retrospective cohort are contacted at least 2 years after surgery (or 1 year after removal) via phone call or letter, informed about the study and asked to participate. In case of informed consent, they are invited to the study site. They are asked to complete the questionnaires and they undergo X-Ray of the affected and the non-affected ankle. All patients in the prospective cohort are informed about the study and asked to participate in the outpatient clinic. In case of informed consent, they are invited to the study site at least 2 years after surgery. They are asked to complete the questionnaires and they undergo na X-Ray of the affected and non-affected ankle.
