Heel bruising is a typical symptom of a heel fracture, so what causes a heel fracture. Heel fracture is the most common of all tarsal fractures, accounting for about 60% of all tarsal fractures. Most of them are caused by vertical impact on the heel after falling from a high place and landing on the foot. So what are the symptoms of heel bruise? I. Symptomatic manifestations Patients with this disease mainly have the following manifestations: 1. post-traumatic injury, heel pain, unfavorable standing, walking. 2, local swelling, pressure pain, deformity, or feel the bone rubbing sound. It is not difficult to determine the fracture based on the typical history of trauma, heel pain and pressure pain, heel bruising, wide and flat deformity, outward tilt of the heel bone, and disappearance of the normal depression below the outer ankle. The angle of intersection of the two lines is called the heel tuberosity line, and the angle of intersection of the two lines is called the heel tuberosity angle (Bhler angle), which is normally 20°-40°. (1) Posterior calcaneal fracture: There are also longitudinal fractures, transverse fractures and avulsion fractures. (2) Anterior calcaneal fracture: the fracture line passes through the anterior calcaneal joint. (3) Talar fracture: The talar process of the heel bone is broken, mostly with displacement. (4) Fracture of the anterior tuberosity near the talocrural joint: In fact, the joint has been affected here, so attention should be paid in the treatment. (2) Articular fracture: depending on the form and degree of damage, it can be divided into the following 4 types: (1) Tongue type fracture: mostly caused by vertical violence. (2) Depression type fracture: also caused by longitudinal vertical external force. (3) stump type fracture: a longitudinal (oblique) fracture that affects the talar dice and heel talar joint. (4) Crush type fracture: Mostly caused by strong compressive violence. The patient’s heel may be extremely swollen, the posterior ankle sulcus may become shallow, and the entire hindfoot may be swollen and painful, which may be misdiagnosed as a sprain. x-ray examination, in addition to the lateral film, should be taken to determine the type and severity of the fracture. In addition, the heel bone is a spongy bone and there is often no clear fracture line after compression, so it is sometimes not easy to distinguish. Only a few cases require CT scan or MRI examination.
