ABSTRACT

Diagnosis: Posterior Shoulder Dislocation

History: 19 y.o. soldier was medically evacuated from XXXX for a shoulder injury sustained on a work detail. He lifted air conditioners out of a truck with the help of another soldier. He denied any fall or other acute trauma. He sought medical treatment at the base clinic. Conservative treatment efforts did not alleviate his pain and he was medically evacuated to a stateside tertiary hospital under the care of the orthopedic service.

Findings: Image 1 is an AP 40 degree oblique radiograph of the right shoulder. Normally, there should be no overlap between the humeral head and glenoid at this angle. Note the slight overlap of the humeral head and the glenoid, which is suggestive of a posterior shoulder dislocation. Image 2 is a lateral, transcapular Y view, which demonstrates that the humeral head is posterior to the glenoid and inferior to the acromion. Image 3 is an axillary view, which again demonstrates the posterior position of the humeral head in relation to the glenoid.

Ddx: posterior shoulder dislocation

Dxhow: Plain radiographic findings are diagnostic

No MeSH data available.


40 degree oblique view: medial border of humeral head is demonstrated by arrow. Note the overlap of the humeral head with the glenoid. In a normal shoulder, there should be no overlap at this angle.
