Abstract: A three-dimensional fracture fixation device is provided for treating clavicle fracture with the intent to protect the supraclavicular nerve from later iatrogenic transsection injury that may occur when the fixation bone plate is removed. The essential components of the three-dimensional fracture fixation device include at least one fixation locking plate, a nerve protection scutum (shield), junctional hooks connecting the fixation locking plate and supporting the nerve protection scutum (shield), and bone screws, which are assembled to form a defined space to accommodate the supraclavicular nerve during open reduction and internal fixation.
