Acute posterior shoulder dislocation (ultrasound)


Posterior shoulder dislocation is not commonly diagnosed on ultrasound as is usually easily seen on x-ray.

This patient presented to our outpatient ultrasound department having had an x-ray at another institution, which was reported as normal.

She then went to have confirmatory x-rays at our institution as well as a subsequent post-reduction CT, which showed the reverse Hill-Sachs defect.
