UPPER LIMB NIGHT BEFORE
Bones & Joints
Clavicle → midshaft fracture → Radial nerve
Humerus → midshaft: Radial nerve; distal: Median/Ulnar nerve
Radius/Ulna → distal fractures; Colles fracture = “dinner fork” deformity
Carpals (8) → Some Lovers Try Positions That They Can’t Handle; Scaphoid
fracture → avascular necrosis risk
Joints:
Shoulder: Ball-and-socket → flex/ext, abduction/adduction, rotation
Elbow: Hinge → flex/ext, minor pronation/supination
Wrist: Condyloid → flex/ext, radial/ulnar deviation
Muscles & Nerves
Elbow flex: Biceps brachii, Brachialis → Musculocutaneous
Elbow ext: Triceps brachii → Radial
Forearm supination: Biceps brachii → Musculocutaneous
Wrist flex: Flexor carpi radialis → Median
Wrist ext: Extensor carpi radialis → Radial
Hand intrinsics: Interossei → Ulnar
Thenar: Opponens pollicis → Median
Clinical Correlations
Wrist drop → Radial nerve
Claw hand (4th/5th) → Ulnar nerve
