title: [Analysis and experimental study of reasons for breakage in the bone fracture plate during internal fixation].
abstract: Bone fracture plate has been in clinical use for internal fixation of fracture, however, during healing, the steel plate breaks occasionally. This paper applied the static strength theory to imitate the pressed down combination out of shape that was borne by single limb of human body standing. Fracture was made on low limbs of the fresh dead body, fixed with a bone fracture plate. Strain measure was made on a bone fracture plate. Additionally, fatigue experiment and four-point bending experiment were carried out on a bone fracture plate. The reason for a breakage in the bone fracture plate was analyzed with static strength theory and low period fatigue theory.
