1. A computer-aided method for fracture reduction, comprising:
acquiring an anteroposterior image and a lateral image of a fracture site, wherein the anteroposterior image comprises an anteroposterior image of a first bone and an anteroposterior image of a second bone, and the lateral image comprises a lateral image of the first bone and a lateral image of the second bone, the first bone and the second bone being two bones at the fracture site;
determining a vector of an axis of the first bone in a spatial coordinate system based on the anteroposterior image and the lateral image of the first bone, and determining a vector of an axis of the second bone in the spatial coordinate system based on the anteroposterior image of the second bone and the lateral image of the second bone; and
determining an included angle between the first bone and the second bone in the spatial coordinate system based on the vector of the axis of the first bone in the spatial coordinate system and the vector of the axis of the second bone in the spatial coordinate system, wherein the included angle is configured to indicate a direction of fracture reduction;
wherein determining the vector of the axis of the first bone in the spatial coordinate system based on the anteroposterior image and the lateral image of the first bone comprises:
acquiring an actual equation of an anteroposterior axis of the first bone based on the anteroposterior image of the first bone, and acquiring an actual equation of a lateral axis of the first bone based on the lateral image of the first bone; and
determining the vector of the axis of the first bone in the spatial coordinate system based on the actual equation of the anteroposterior axis of the first bone and the actual equation of the lateral axis of the first bone; and
determining the vector of the axis of the second bone in the spatial coordinate system based on the anteroposterior image of the second bone and the lateral image of the second bone comprises:
acquiring an actual equation of an anteroposterior axis of the second bone based on the anteroposterior image of the second bone, and acquiring an actual equation of a lateral axis of the second bone based on the lateral image of the second bone; and
determining the vector of the axis of the second bone in the spatial coordinate system based on the actual equation of the anteroposterior axis of the second bone and the actual equation of the lateral axis of the second bone.
