Symptomatic vertebral hemangiomas: a report of four cases.

Neural compression complicating vertebral hemangioma is associated with: compression fracture, hematoma, epidural extension of tumor, and/or bony expansion or "ballooning." Four cases of symptomatic vertebral hemangioma are presented. Discussion includes imaging modalities, preoperative embolization, and surgical approach.

Combined ankle and subtalar instability.

Ipsilateral ankle and subtalar instability has been alluded to in the orthopaedic literature. A case demonstrating this combined instability pattern is presented and a technique for documenting this disorder is described.

Elbow injury: a new imaging approach.

The authors describe a new technique for evaluating traumatic conditions to the elbow: the radial head-capitellum view. This projection has proved useful in demonstrating minimally displaced or nondisplaced fractures of the radial head, capitellum, and coronoid process. The radial head-capitellum view not only delineates the fracture, it also defines the extent of displacement.

A comparative study of the electrophysiologic effects of Striadyne, adenosine triphosphate and adenosine in the canine heart.

The chronotropic and dromotropic effects of the intra-atrial administration of 0.97, 1.93 and 2.90 microM/kg Striadyne, the pharmaceutical form of adenosine triphosphate (ATP) for clinical use, ATP, and adenosine, were compared in 13 anesthetized dogs. Striadyne, ATP and adenosine exerted transient dose-dependent negative chronotropic and dromotropic effects. There was no significant difference between the electrophysiologic effects of Striadyne and ATP which were significantly more pronounced than those of adenosine. Atropine (0.2 mg/kg) significantly attenuated the electrophysiologic effects of 2.90 microM/kg Stridyne and ATP but not those of adenosine. It is concluded that Striadyne and ATP have similar electrophysiologic effects which are more pronounced than those of adenosine mainly due to vagal involvement in their mechanism of action.

Radial head-capitellum view in elbow trauma: clinical application and radiographic-anatomic correlation.

The radial head-capitellum view, first reported 2 years ago, has proved useful in the evaluation of elbow trauma. Minimally displaced or nondisplaced fractures of the radial head, capitellum, and coronoid process are better demonstrated on this special projection than on traditional radiographs of the elbow. To test the accuracy of this view, 50 patients with trauma to the elbow were examined and routine anteroposterior, lateral, and external oblique radiographs were compared with this special angled projection. In 10 patients, the conventional studies either were negative or failed to show the full extent of the fracture, whereas the radial head-capitellum view demonstrated the abnormality in every case. A human cadaver elbow specimen was used in a radiographic anatomic correlative study to further confirm the usefulness of this technique. It revealed that fractures of the posterior half of the radial head were particularly difficult to diagnose on the traditional lateral view. The radial head-capitellum view not only distinctly delineated these fractures, it showed the full extent of their articular displacement. The authors recommend the use of this technique in all cases of chronic and acute trauma to the elbow joint.

The pelvic digit.

The authors present an illustrative case report of "pelvic digit" and discuss this benign skeletal anomaly. The similarity of this condition to posttraumatic myositis ossificans, avulsion injuries of the pelvis, and osteochondroma is pointed out.

Rheumatoid arthritis simulating other lesions.

Radiographs of patients with rheumatoid arthritis can sometimes be misleading. Seven of 69 patients with RA had radiographs sufficiently atypical to lead clinicians to suspect other disorders (e.g., gout, lupus erythematosis, thrombophlebitis). Five of these cases are presented and the diagnosis in each case is discussed.
