There is a piece of heel bone fracture that is not necessarily a comminuted fracture. Fractures of the heel bone can be categorized as transverse fractures of the heel bone, avulsion fractures of the calcaneal tuberosity, and comminuted fractures of the heel bone. A comminuted heel fracture can be diagnosed if the patient has more than 2 fragments of the heel bone, or if the fragments are T-shaped or Y-shaped. If a fragment of bone is present after a heel bone fracture, it is not necessarily a comminuted fracture. A comminuted fracture of the heel bone usually results in a disruption of normal anatomy. X-rays may show breakage, displacement and dislocation of the heel bone. Therefore, it is not enough to judge whether the fracture is a comminuted fracture based on the presence of a fragmented piece of bone in the heel bone fracture alone, and it is necessary to make a comprehensive judgment through a combination of various examinations. If there is a fracture of the heel bone, it is recommended to go to the hospital to take pictures to confirm the type of fracture, and under the guidance of the doctor to carry out targeted treatment.
