Osseous drill holes to promote granulation tissue: radiologic appearance.

Skin grafting following extensive soft-tissue loss is often delayed until adequate granulation tissue can be generated. Surgical drill holes into the marrow cavity promote development of granulation tissue. This article illustrates the radiology appearance of these drill holes in four patients.

Protocol-driven radiologic evaluation of suspected cervical spine injury: efficacy study.

The American College of Surgery currently recommends routine performance of lateral cervical radiography of C-1 to C-7 for all patients admitted with a history of major blunt trauma. A survey of 125 North American hospitals with experience in acute trauma care revealed that 96% obtain cervical radiographs as a routine or protocol study on all patients who have suffered major blunt trauma. To ascertain the cost-benefit effect of this practice, a prospective study was conducted during a 19-month period to compare the results of admission bedside clinical assessment of the cervical spine and the outcome of cervical radiography and computed tomography (CT) performed on 408 patients admitted with a history of major blunt trauma.

Mediastinal tumors presenting as spontaneous hemothorax, simulating aortic dissection.

The usual causes of hemomediastinum and hemothorax include chest trauma, rupture of an aortic aneurysm or aortic dissection. We report two patients who presented with a clinical picture of aortic dissection. In both patients, the chest radiograph revealed anterior mediastinal masses.
