  4. Anatomy?

  5. Axillary view AC Joint Glenoid Acromion

  6. Pathology?

  7. Bilateral Clavicle fx

  9. Pathology?

  10. Anterior glenohumeral (shoulder) dislocation. How do we know it is anterior?

  11. Anterior glenohumeral (shoulder) dislocation. The fact that we see the humeral head in profile tells us it is externally rotated (it would be internally rotated if the patient was dislocated posteriorly.) An internally rotated humeral head looks like a “light bulb”.

  13. We can also obtain an “axillary view” and see that the humeral head is anterior to the glenoid. Anterior glenohumeral (shoulder) dislocation.

  14. Anatomy?

  15. Anatomy? Trapezius Acromion Supraspinatus Supspinatus tendon Glenoid Subscapularis Deltoid

  16. Pathology?

  17. Rotator Cuff tear (tendon should be black)

  18. Anatomy?

  19. Anatomy? Olecranon/coronoid fossa Medial epicondyle Capitellum Trochlea Radial Head Radial Tuberosity

  20. Anatomy?

  21. Anatomy? Olecranon/coronoid fossae Radial head Coronoid process Olecranon

  22. Pathology?

  23. Supracondylar fracture of the humerus in a child

  24. Pathology?

  25. Posterior dislocation of elbow

  26. Pathology?

  27. Proximal ulna fracture With fracture subluxation of radial head This combination of injuries is known as a “Monteggia fracture.”

  28. Pathology?

  29. Elbow fracture dislocation Fracture of the olecranon with anterior dislocation of radius and ulna. Air in soft tissues indicates that it is an “open” fracture.

  30. Pathology?

  31. Fracture of the radius and ulna

  32. Pathology?

  33. Distal radial “buckle” or “torus” fracture. The bone has “crumpled” rather than broken.
