When the broken bones make the ankle unstable, surgeons usually fix them with metal screws and plates. Metal hardware holds the bones in place well, but it can cause irritation, can loosen or break, and often has to be removed in a second surgery later.\n\nThis study looks at a different kind of screw called the RemeOs magnesium-based screw. It is made from a magnesium alloy and is designed to slowly dissolve and be absorbed by the body over about two to three years after it has done its job of holding the bone together. Because it dissolves on its own, patients may not need a second surgery to remove the hardware. These screws are authorized by the U.S. Food and Drug Administration (FDA) for use in medial malleolus ankle fractures. In this study, they are being used as an off-label indication.\n\nThe purpose of this study is to learn how well these magnesium screws work and how safe they are when used to repair unstable ankle fractures. The study will enroll at least 25 adults (ages 18 to 80) who have an unstable ankle fracture that needs surgery. All participants will have their fracture repaired with RemeOs screws as part of their normal surgical care.\n\nAfter surgery, participants will be followed for 12 months. They will return for check-ups at about 6 weeks, 3 months, 6 months, and 12 months. At these visits, the study team will examine the ankle, take X-rays to see how the bone is healing and how the screws are dissolving, ask about any complications, and have participants fill out questionnaires about their ankle function and pain.\n\nThe main thing the study measures is ankle function at 12 months, scored using a standard ankle questionnaire (the Olerud-Molander Ankle Score). The study also tracks pain, healing on X-rays, how the screws break down over time, and any complications such as infection, loss of fixation, non-healing, or the need for additional surgery.\n\nThe surgery, X-rays, and follow-up visits in this study are the same care patients would receive whether or not they take part. The only research-specific parts are giving consent and filling out the study questionnaires. Taking part is voluntary and does not change the care a patient receives.",[66,67],"Ankle Fractures","Syndesmotic Injury",[69,70],"Magnesium-based screw","Biodegradable implant","NOT_YET_RECRUITING","2026-07-24",{"date":74,"type":75},"2026-07-27","ACTUAL",{"date":77,"type":60},"2026-08",{"date":79,"type":60},"2029-03",{"name":5,"class":6},1]
