Using 3D printing to treat lower limb bone defects

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study focuses on the diagnosis and treatment of lower limb bone defects using a novel 3D printing technology developed by the Orthopedics Department of Peking University Third Hospital. The TCBridge system allows for personalized and accurate repair of significant bone defects, enabling patients to safely bear weight and engage in functional exercises shortly after surgery. By establishing a multi-center clinical case cohort, the study aims to gather comprehensive data on the effectiveness of this innovative approach in treating various types of bone defects.
