Weber B Ankle Fractures With Associated Posterior Malleolus Fracture

ClinConnect Summary

This clinical trial is looking at the best way to treat specific types of ankle fractures, particularly those that include a small piece of bone at the back of the ankle called a posterior malleolus fracture. Researchers want to find out if fixing this bone fragment during surgery leads to better recovery and outcomes for patients compared to not fixing it. Ankle fractures are quite common, and there's still a lot of debate among doctors about the best treatment approach, especially since many practices are based on tradition rather than solid evidence.

To participate in this study, patients should be between 18 and 65 years old and have a specific type of ankle fracture known as Mason and Molly type 2A or 2B, along with a Weber B fracture. They must also have a noticeable displacement of the posterior malleolus. Eligible participants will be randomly assigned to either have the bone fragment fixed during surgery or not. The study is taking place at several hospitals in Norway, and by gathering more information, it aims to help establish clearer guidelines for treating these types of fractures in the future. If you choose to participate, you can expect to receive careful monitoring and support throughout the process.
