Upper Limb Nerve Entrapments Flashcards
What radial nerve entrapment involves compression of the radial nerve against the head of the humerus with weakness in all radial nerve innervated muscles and sensation over the dorsal lateral hand, thumb, and fingers?
Crutch Palsy
What radial nerve entrapment involves compression of the radial nerve from prolonged stretch in spiral groove of humerus under the common insertion of the deltoid and triceps which roofs over the spiral groove of the radial nerve causing everything weak except for the triceps?
Saturday Night Palsy
What radial nerve entrapment of the deep radial nerve (motor) as it passes thru the Arcade of Froshe in the supinator leading to weakness of the finger and wrist extensors?
Supinator Palsy (does not involve the Supinator though)
What Radial nerve entrapment causes compression of the superficial radial nerve as it enters the hand causing sensory loss over the dorsal lateral hand, thumb, and fingers?
Handcuff Palsy
What Ulnar nerve entrapment causes compression from holding head in hand with elbow flexed on edge of table, trauma to nerve from hitting a point (table, countertop, etc)?
Retrocubital compression
What Ulnar nerve entrapment creates repetitive episodes of medial epicondylitis resulting in a thicken roof over tunnel compressing nerve in the tunnel creating weakness in ulnar hand muscles, decreased sensation in proper digital ulnar, palmar ulnar and dorsal ulnar nerves?
Cubital Tunnel syndrome
What involves the ulnar nerve that creates Repetitive episodes of medial epicondylitis resulting in a thicken roof over tunnel compressing nerve in the tunnel creating weakness in ulnar hand muscles, decreased sensation in proper digital ulnar, palmar ulnar and dorsal ulnar nerves.?
Cubital Tunnel syndrome
What causes weakness in ulnar innervated hand muscles, sensation loss over palmar aspects of medial one and a half digits?
Pisiform-Hamate Syndrome
What is another name for Pisiform-Hamate Syndrome?
Entrapment of the canal of Guyon
What median nerve entrapment can compress median nerve leading to a Pronator syndrome with a weak pronator and sensory loss over palmar aspect of lateral 3 1⁄2 digits and skin over thenar eminence?
Ligament of Struthers
What median nerve entrapment involves poorly localized forearm pain and weakness of flexion of the DIP joint of Digit 1 (flexor pollicis longus) and the DIP joints of Digit 2 & 3 ( flexor digitorum profundus of digits 2 & 3). Patient cannot make an “OK” sign with their thumb and index fingers as DIP joints do not flex due to muscle weakness.
Anterior interosseous nerve
What median nerve entrapment involves weakness in all median muscles distal to the pronator teres?
Pronator syndrome
What median nerve entrapment involves compression of the median nerve in the carpal tunnel with weakness of median innervated intrinsic hand muscles?
Carpal Tunnel syndrome
