Elbow dislocations are classified by the position of the radio-ulnar joint relative to the humerus.1 Images 1, 2, and 3 show a left posterior elbow dislocation; the radius and ulna (red lines) are displaced posteriorly with respect to the distal humerus (blue line). The lateral view of the elbow most clearly shows this: trochlear notch of the ulna (red line) is empty and displaced posteriorly relative to the trochlea (blue line). There is no associated fracture. Images 4 and 5 show the elbow status-post reduction, demonstrating proper alignment of the distal humerus (blue line) with the radius and ulna (red lines).

Physical exam revealed an open dislocation of the proximal interphalangeal joint (PIP) of the right fifth digit. X-ray confirmed dislocation and revealed no fractures. The patient received a tetanus booster, Cefazolin, and the dislocation was then washed out and reduced. Multiple reduction attempts were made and were only successful once the metacarpophalangeal joints were held in 90 degree flexion, which relaxed the lateral bands and enabled the finger to be reduced.

Chest x-ray and bedside ultrasound revealed a large right pleural effusion, estimated to be greater than two and a half liters in size.

Hampton’s Hump in Pulmonary Embolism

DOI: https://doi.org/10.21980/J83W27Issue 1:1[mrp_rating_result]

In the lateral view chest x-ray, there is a Hampton’s Hump, a pleural based, wedge-shaped opacity at the base of the right lung, representing lung infarction (black arrow). These findings correlate with the sagittal view on CT angiography of the chest. The CT chest also shows a filling defect in the distal posterior basal segmental pulmonary artery (white arrow), as demonstrated by the absence of contrast enhancement in the distal portion of the vessel. This is associated with an opacification of the lung parenchyma distal to the occlusion (red arrow), representing lung infarction.
