Significant new observations on cervical spine trauma.

The results of a computer analysis of 399 patients with documented fractures and/or dislocations of the cervical spine are summarized. Vertebral arch fractures were present in half of all patients with radiographic evidence of cervical spine trauma. Two-thirds of the patients had two or more injuries. Isolated disk injuries were rare and, when present, were characterized by a vacuum sign. The dens fracture, with or without atlantoaxial dislocation, was rarely associated with injury elsewhere in the cervical spine. The study suggests that the routine five-film cervical spine examination is inadequate to detect the most common traumatic lesions. Thus vertebral arch views (pillar views) should be obtained if there is evidence to suggest hyperextension as the mechanism of injury. In addition, the study underscores the importance of aggressively searching for multiple abnormalities.

Horizontal fracture of the anterior arch of the atlas.

Horizontal fracture of the anterior arch of the atlas can be easily overlooked on lateral radiographs. The fracture is not associated with neurological deficit but may be the cause of severe pain. A review of the literature reveals only 3 previously reported cases. Seven new cases, including 2 without other cervical spine fractures, indicate a much higher incidence than was previously thought. Hypotheses about the mechanism of injury are discussed.

Toxopachyosteose diaphysaire tibio-peroniere (Weismann-Netter-Stuhl syndrome): two case reports.

Two patients with the Weismann-Netter-Stuhl syndrome are presented, one with classic and widespread findings, the other with minimal changes. Subsequent to its initial description in the French literature seven cases have been reported in English. The syndrome is characterized by anterior bowing of the tibia and fibula with posterior cortical thickening and trabecular irregularity in the region of bowing. Other long bones may be similarly affected. Scoliosis and pelvic findings are frequent. Short stature is usually present. The syndrome appears to be a generalized diaphyseal dysplasia.

Kaposi's sarcoma in bone: a case report with unusual radiographic findings and an abnormal radioisotope scan.

The authors present a case report of Kaposi's sarcoma involving the bones of the forearm, wrist, and hand. Typical features of rarefaction, osteoporosis, cysts, and cortical erosions were present. Rarely seen changes of a bubbly expansion of the lesions and periosteal reaction were also present. This is the first radioisotope bone scan reported in Kaposi's sarcoma to the author's knowledge. The literature about osseous manifestations of Kaposi's sarcoma is reviewed.

Computed tomography in the evaluation of severe facial trauma.

Computed tomography (CT) is a simple, rapid, and safe method of evaluating patients with severe facial trauma. It has its greatest value in defining the extent of soft tissue damage as well as in assessing the skeletal disruption. In a group of 32 patients with severe facial trauma, CT outlined the degree of soft tissue and skeletal fracture. In 13 of these patients who also underwent conventional pleuri-directional tomography CT was determined to be just as effective in identifying all fractures. CT was also shown to be useful for follow up evaluation of patients with previous severe facial trauma.
