Answer to Trivia Question…

This is an inferior dislocation at the glenohumeral joint, otherwise known as Luxatio Erecta Humeri

Luxatio Erectae

Inferior dislocation accounts for less than 0.5% of shoulder dislocations.  The characteristic clinical finding is that the patient holds their arm up as if wanting to ask a question in class.

Biker hit by car…

This is a humerus radiograph of a biker who was “clipped” by a car and fell on their side:

Humerus fx 2Humerus fx 1

The image shows a comminuted fracture of the proximal humerus.  It is important, as discussed on past posts, to ensure the axillary nerve is intact as well as the axillary artery.  The other important consideration in this case is obtaining a “Y” or “Axillary” view of the shoulder to make sure you aren’t missing a dislocation either anterior or posterior to the glenoid fossa.

Shoulder pain…

This patient had a fall on his shoulder and had pain, deformity of the shoulder.  Here are his radiographs:

This is a simple radiograph of an anterior glenohumeral dislocation (shoulder dislocation).  One can see the importance of a good Y-view (second image)  or an Axillary view (not seen here).  These alternate views help determine if the shoulder is anteriorly or posteriorly dislocated.  Knowing this will help aid in proper reduction.

Lesson is:  always get two views with radiographs.  (mainly directed at early medical learners, forgive me if you experienced learners just yawned)

Left Inferior Glenohumeral Dislocation (Shoulder dislocation)

It is very important to develop an algorithm when looking at imaging, ekgs, etc.  In my routine evaluation of an xray the last thing I do is look at the bones.  In this image if one looks at the left shoulder you can see an inferior glenohumeral dislocation, otherwise known as luxatio erecta.  This was read by the attending radiology physician as no traumatic pathology.  As the ED physician I had the luxury of knowing the patient couldn’t adduct her arm and it was easily caught on xray.
