Worst Hill Sachs Fracture Ever!!!

So bad it sheared the greater tuberosity right off.  No Bankart, but I guess the glenoid is so tough that it forced the humerus to take all the energy.



Knee Dislocation

A very uncommon but also very important event.  There is an association with popliteal artery injury, be it dissection or transection/laceration.


  • anterior and posterior dislocations most common
    • in my experience, posterior dislocations much more common, but sample bias is substantial because this is a rare event
  • structural disruption of the knee joint including cruciate ligaments and collateral ligaments, often with associated meniscal tears.
    • on MRI, the knee is usually “trashed”.
    • reports end up being lengthy because of the extent of injury.
  • Fractures common.
  • associated popliteal artery injury estimated at 30%.


Glenoid Avulsion of the Glenohumeral Ligament (GAGL)

This is a fairly uncommon finding but the findings in this case are clearly posttraumatic. There is an impaction fracture the greater tuberosity and the labrum is essentially circumferentially torn even though the tear is not visible in the posterior labrum. Although not visible, it is still likely present. The glenoid avulsion of the glenohumeral ligament is clearly visible on the annotated images.
