Methods: Establishing three dimensional model and finite element analysis we calculated the stress in and around the fracture faces when distal radius fracture was fixated with DRMC. Results: Axial holding stress produced by holding part of DRMC on distal radius was 14. 66 MPa. The maximum stress of holding part was 40-70 MPa the minimum stress was 3-7 MPa and the stress of compression part was 20 - 40 MPa. Conclusion: The distribution of stress produced by DRMC around the fracture line is reasonable and axial holding stress can help stabilize fracture during earlier period. The existence of longitudal compression and memory effect can transfer fixated disused section into developed section and enhance fracture healing.
