Symptoms of an<unk>  can be similar to those of<unk>  sprains (pain, swelling, limited range of motion), though typically they are often more severe by comparison. It is exceedingly rare for the<unk>  joint to dislocate in the presence of ligamentous injury alone. However, in the setting of an<unk> , the talus can become unstable and subluxate or dislocate. Patients may notice ecchymosis ("black and blue" coloration from bleeding under the skin), or there may be an abnormal position, alignment, gross instability, or lack of normal motion secondary to pain. In a displaced, fracture the skin is sometimes tented over a sharp edge of broken bone. The sharp fragments of broken bone sometimes tear the skin and form a laceration that communicates with the broken bone or joint space. This is known as an open fracture and has a high incidence of infection if not promptly treated.<unk>  anatomy
