If your median nerve is severed, what action is most likely affected
Pronation
If you break off the coronoid process of ulna, what action is most likely affected?
Extension/flexion
A patient falls on an outstretched hand, you suspect
Colle’s fracture: distal radius
Limiting structures of flexion
L: posterior radiocarpal and posterior part of joint capsule
Limiting structure of extension (wrist)
L: anterior radiocarpal and anterior part of joint capsule
B: opppostion between radius and carpal bones
Limiting structure of abduction (wrist)
L:UCL and medial joint capsule
B: opposition between styloid process of radius and scaphoid
Limiting structure of adduction
L:radial collateral and lateral part of joint capsule
Action of supraspinatus
Abduction for fist 15 degrees
Action of infraspinatus
External rotation of humerus, stabilization
Action teres minor
