Comminuted fracture of the left heel is a relatively common fracture in clinical practice, and most of the fractures are caused by a direct external force. When a comminuted fracture of the left heel occurs, the first treatment is conservative, and the patient can be instructed to rest in bed, elevate the affected limb, perform a manual repositioning under anesthesia, and give a plaster brace or brace for external fixation after successful repositioning. After successful repositioning, external fixation such as plaster brace or brace is given. Then, X-ray of the fracture site is reviewed regularly to observe the position of the fracture. If the conservative treatment is not satisfactory, surgery can be considered as the next step. An incision can be made and internal fixation such as a hollow nail, kerfing pin or plate can be given. After the occurrence of a comminuted fracture of the left heel, the patient should consult a doctor promptly and take the correct treatment after the correct diagnosis by the doctor in order to recover the fracture as soon as possible.
