Whether or not the free bone fragments of the heel, talus and navicular bone of the right foot need to be removed mainly depends on the size of the free bone fragments, whether or not there is a possibility of entering the joint and whether or not the bone fragments will affect the healing of the fracture and other factors. 1. Size of free bone fragments: Generally speaking, free bone fragments are small, and the displacement is small, so most of them do not need to be removed. On the contrary, if the fracture fragment is large, which may affect the fracture healing or even lead to deformity, most of the time it is recommended to take it out or give incision and fixation. 2. Whether it enters into the joint: if there is a risk that the fracture fragments will enter into the joint and lead to joint compression, then it needs to be taken out in time. 3. Whether the fracture block interferes with fracture healing: If the fracture block is large and interferes with fracture healing or deformity healing, it needs to be removed or incised for internal fixation. Whether the fracture block needs to be removed or not, it is necessary to take x-ray examination, and if necessary, also need to take CT and three-dimensional reconstruction examination to determine the size and location of the fracture block, and then determine the specific treatment plan under the guidance of specialists.
