Annular ligament tear and/or radial head subluxation from annular ligament
30
What are the symptoms of radial head instability and/or Nursemaid's elbow?
Pain with palpation of radial head with anterior displacement of the radial head, and restriction to posterior glide
31
What coupled motions are present at the ulna and radius with supination of the elbow?
Ulnar adduction Radial head anterior glide
32
What coupled motions are present at the ulna and radius with pronation of the elbow?
Ulnar abduction Radial head posterior glide
33

80-90
34
Normal ROM for extension of the wrist
70
35
Normal ROM for adduction of the wrist
30-40 | This is ulnar deviation
36
