Definitions
- the osteosynthesis plate 5 consists of a thermoplastic material which can be deformed at a temperature slightly above body temperature, but which is dimensionally stable at body temperature.
- a material can be, for example, a modified methacrylate, in particular a polyethyl methacrylate, which can be deformed at a temperature of approximately 50 ° C.
- Reinforcing fibers 9 are embedded in the plastic mass, for example continuous carbon fibers, which on the one hand reinforce the osteosynthesis.
