Luxatio erecta humeri is a rare type of inferior glenohumeral dislocation with a unique radiographic appearance; however, the magnetic resonance imaging findings associated with this dislocation have not been described in the radiology literature. The purpose of this study is to identify magnetic resonance imaging findings associated with this uncommon type of glenohumeral dislocation. ⋯ Common magnetic resonance imaging findings in patients with a prior luxatio erecta humeri dislocation include rotator cuff tears, injury to the glenoid labrum, and injury to both the anterior and posterior bands of the inferior glenohumeral ligament. These findings are compatible with the mechanism of dislocation in luxatio erecta, and noting these findings on magnetic resonance imaging may suggest that the patient has sustained a prior inferiorly directed glenohumeral dislocation such as luxatio erecta.

There is still a paucity of information about the clinical presentation, treatment and imaging findings of latissimus muscle tears. Only one study has specifically described the magnetic resonance imaging (MRI) features of latissimus tendon tears. We describe a case of a high-grade tear in the latissimus muscle tendon in an active water skier with no significant prior medical history. MRI demonstrated at least a 50% tear of the latissimus tendon, manifesting as increased signal intensity on T2-weighted sequences and surrounding edema, as well as a diminutive tendon at the humeral insertion.

Cervical transforaminal epidural steroid injection for the management of cervical radiculopathy: a comparative study of particulate versus non-particulate steroids.
To determine if a particulate steroid which has a risk for embolic infarct would be more effective than a non-particulate steroid for transforaminal epidural steroid injection (TFESI). The purpose of this study was (1) to compare the effect of cervical TFESI using particulate (e.g., triamcinolone) and non-particulate (e.g., dexamethasone) steroids and (2) to evaluate the effectiveness of cervical TFESI in general. ⋯ There was no significant difference between particulate or non-particulate steroid for the effect of cervical TFESI. Cervical TFESI was effective in managing cervical radiculopathy in general.

To investigate features of crush extremity fractures associated with massive earthquake on digital radiography (DR) and multidetector computed tomography (MDCT). ⋯ Multiple and comminuted fractures, predominantly in the lower extremities, could be considered as features of crush extremity fractures associated with the massive Sichuan earthquake.

The aim of this research was to survey how occult fractures of the scaphoid bone are both imaged and managed initially. ⋯ The survey revealed a wide variation in the management of occult fractures of the scaphoid. MRI has been shown to be both sensitive and specific in diagnosing occult carpal bone fractures. There is a need to standardise the management of these injuries to ensure early diagnosis and limit unnecessary wrist immobilisation.
