Final answer:
The question regarding the sizes in which PPFx proximal Femur plates come is not explicitly answered in the provided context. Proximal femur plates are used in surgeries to stabilize femoral fractures and their sizing is crucial for effective fixation.
Step-by-step explanation:
The proximal femur plates are medical devices used to provide stabilization and fixation of femoral fractures. Their sizing typically corresponds with the anatomical variation and the size of the femur in different individuals. In practice, these plates can come in a variety of sizes; however, the specific options available for the PPFx proximal Femur plates, as mentioned in the given context, are not provided. It's important for surgeons to select the proper size to ensure correct placement and effectiveness of the fixation, keeping in mind the complex ossification process of the femur bone and the changes it undergoes throughout development. Secondary ossification centers, as well as the appearance and fusion of epiphyseal plates, are critical to the accurate interpretation of radiographic images and the appropriate management of fractures in both children and adults.
