Palmar dislocation of the trapezoid is a rare injury, which results from substantial trauma to the wrist. It is associated with other bony or ligamentous injuries in the wrist. ⋯ Treatment of choice is open reduction and internal fixation, which generally achieves good functional results. We describe a new case of palmar dislocation of the trapezoid and review the world literature with emphasis on the radiographic findings.

Eosinophilic fasciitis in a military recruit: MRI evaluation with clinical correlation.
Eosinophilic fasciitis (EF) is an uncommon connective tissue disease. We report a patient with EF who presented with episodic swelling and stiffness of his legs and forearms in combination with peripheral eosinophilia. ⋯ The complete clinical imaging and pathological findings are described in this report. Cross-sectional imaging is useful in diagnosing EF and in the appropriate clinical scenario may be helpful in differentiating EF from other connective tissue diseases.

Review Comparative Study
Magnetic resonance imaging in the evaluation of ligament injuries.
Magnetic resonance imaging has had a dramatic effect on the means by which we diagnose ligament injuries. Tears resulting from either acute trauma or overuse can be detected noninvasively, directing appropriate therapy be it conservative or surgical. For the elite athlete, earlier diagnosis leads to earlier intervention, or alternatively, a normal MRI examination can result in an earlier return to play. While MRI is accepted for the diagnosis of certain injuries such as complete tears of the cruciate ligaments of the knee, other injuries, such as partial cruciate ligament tears or tears of the intercarpal ligaments of the wrist, remain controversial.

The case of a 51-year-old man with Ewing's sarcoma of the thumb is presented. The tumor involved the distal phalanx of the right thumb, associated with an impressive extraskeletal mass. Histology revealed a round cell sarcoma with a positive immunoreactivity with monoclonal antibody O13. Five years after disarticulation at the metacarpophalangeal joint, the patient is alive without recurrence or metastasis.

Luxatio erecta of the hip: a critical retrospective.
The term "luxatio erecta" has been borrowed from the shoulder to identify rare traumatic hip dislocations in which there is inferior dislocation of the femoral head and inversion of the femoral shaft. A review of the literature is presented along with an additional illustrative case. The mechanism of injury, and the radiological and physical appearance of the patient, indicate that there are two subtypes of dislocation hitherto lumped together under the single term.
