Yes...the shoulder is dislocated, but did you notice anything else? (see figure 1)

Glenoid Fossa Fracture: (Image submitted by Dr. George Kochman)

Fractures of the glenoid fossa occur when the head of the humerus collides with the glenoid margin; classically, by a laterally directed force. Although less than 10% of glenoid fossa fractures result in significant displacement, surgical repair is indicated if: 

• Fracture displacement >10mm
• >33% involvement of posterior glenoid fossa
• >25% involvement of anterior glenoid fossa
• Persistent humeral head subluxation

Ectopic Pregnancy Pearls

1. Considering the history above, transvaginal ultrasound should be performed regardless of quantitative beta-HCG; even if below the discriminatory zone (<1500-1800)
2. Transvaginal ultrasound suggests ectopic pregnancy (as in the case above), with an empty uterus and free pelvic fluid (Figure 1).
3. The above history plus free abdominal fluid on FAST exam also suggests the diagnosis and should expedite management (Figure 2). 
4. Please remember that ~15% of ectopic pregnancies present with normal menses.

Many thanks to Dr. George Kochman for submitting this case!
