“…Although this kind of injury will seldom be a radiologic diagnosis, tympanic membrane rupture should be kept in mind in regard to patients who are exposed to explosive blasts (Fig 4). The initial blast wave can also cause ossicular fractures and dislocations (20,21). Although less important in the acute phase of injury triage, these injuries can be diagnosed at dedicated thin-section CT of the temporal bone (22).…”

Although most trauma centers have experience with the imaging and management of gunshot wounds, in most regions blast wounds such as the ones encountered in terrorist attacks with the use of improvised explosive devices (IEDs) are infrequently encountered outside the battlefield. As global terrorism becomes a greater concern, it is important that radiologists, particularly those working in urban trauma centers, be aware of the mechanisms of injury and the spectrum of primary, secondary, tertiary, and quaternary blast injury patterns. Primary blast injuries are caused by barotrauma from the initial increased pressure of the explosive detonation and the rarefaction of the atmosphere immediately afterward. Secondary blast injuries are caused by debris carried by the blast wind and most often result in penetrating trauma from small shrapnel. Tertiary blast injuries are caused by the physical displacement of the victim and the wide variety of blunt or penetrating trauma sustained as a result of the patient impacting immovable objects such as surrounding cars, walls, or fences. Quaternary blast injuries include all other injuries, such as burns, crush injuries, and inhalational injuries. Radiography is considered the initial imaging modality for assessment of shrapnel and fractures. Computed tomography is the optimal test to assess penetrating chest, abdominal, and head trauma. The mechanism of blast injuries and the imaging experience of the victims of the Boston Marathon bombing are detailed, as well as musculoskeletal, neurologic, gastrointestinal, and pulmonary injury patterns from blast injuries.

“…In the present case, a distortion force may have induced fracture of the posterior crus of the stapes, as also reported for stapes dislocations following head injury [5]. In patients with persistent conductive hearing loss and imaging considered to be normal, some authors recommend surgical exploration to demonstrate and simultaneously treat the ossicular lesion [6]. We emphasize the importance of early tympanometry, which may suggest dislocation of the ossicular chain in the presence of increased compliance.…”

“…To our knowledge, no case of isolated fracture of the posterior crus of the stapes has been previously reported. The low incidence of this site can be explained by the anatomy of the stapes, as the posterior crus is protected by the annulus and supported by the stapedius tendon [6]. In the present case, a distortion force may have induced fracture of the posterior crus of the stapes, as also reported for stapes dislocations following head injury [5].…”
