Epiphyseal fracture of the lower end of the left fibula mainly occurs in children, and it is relatively serious because the epiphysis affects bone growth. Epiphyseal fracture is a common type of fracture in children. Clinically, epiphyseal fractures are categorized into five types according to the X-ray presentation of the fracture: type 1 simple epiphyseal fracture; type 2 epiphyseal fracture with triangular-shaped epiphyseal bone fragments attached; type 3 epiphyseal fracture is separated from the plate; type 4 fracture is passed through the epiphyseal part, epiphyseal plate, and enters into the joint; and type 5 epiphyseal fracture is completely separated. Regardless of the type of epiphyseal fracture, closed reduction internal fixation, incision reduction internal fixation, or external fixation bracing is required. Epiphyseal fractures of the lower limbs are often more serious than those of the upper limbs because the epiphysis determines the growth of the bone, which is mainly dependent on the long bones of the lower limbs, and the bones of the lower limbs are load-bearing, which is likely to result in shortening deformity after epiphyseal fracture or unequal lengths of lower limbs due to the stagnation of the growth of the lower limbs due to the injury. If a fracture of the lower epiphysis of the left fibula is diagnosed, early treatment is recommended to minimize the adverse effects of the disease.
