Light at the end of the Tunnel
Flexor Digitorum Superficialis (4), Flexor Digitorum Profundus (4), Flexor Pollicis Longus (1) and the Median Nerve
The tendons of the wrist enter through this many dorsal compartments
Muscle action does not directly affect movement of the carpal bones. True of False?
True
This muscle is deep to both the Flexor Digiti Minimi Brevis and Abductor Digiti Minimi
What is Opponens Digiti Minimi
Chronic Median Nerve damage. Digits 1-3 are extended and cannot be flexed.
Sign of Benediction
Extensor Pollicis Brevis and Abductor Pollicis Longus run through this compartment
What makes up the radio-carpal joint?
The scaphoid and lunate articulate with the distal radius, functioning as a synovial condyloid joint.
Opponens Pollicis is deep to these 2 Thenar Muscles
What are Flexor Pollicis Brevis and Abductor Pollicis Brevis
Erb's palsy is damage to the upper rachial plexus and affects the shoulder/elbow.
Klumpke's palsy is damage to the lower brachial plexus and affects the hand.
These 2 structures run superficial to the Volar Carpal Ligament
The Palmaris Longus Tendon and the Palmar Cutaneous Branches
The 3rd compartment only has this structure traveling through it
The Extensor Pollicus Longus
This structure lies between the Ulna and the Triquetrum
The Triangular Fibrocartilagenous Complex
The Hypothenar muscles are on this side of the hand
Medial side (pinky side)
Median nerve is injured. Weakness in the anterior forearm. Paresthesia in hand ( digits 1-3 and the palm)
Pronator Teres Syndrome
These are the 4 structures that travel between the ligaments
Ulnar nerve and Ulnar artery, Flexor Carpi Ulnaris and Flexor Carpi Radialis
Extensor Digiti (Communis) and Extensor Indices (Proprius) travel through this compartment
The 4th compartment
The Palmar (limits supination) and Dorsal (limits pronation) Radio-Ulnar Ligaments
There are 3 Palmar Interorssei, where do they sit and what action do they cause
Between digits 2+3, 3+4, 4+5. They cause adduction of the fingers
Long standing Ulnar nerve damage. Hyperextension of the MCPs. Flexion of the PIPs and DIPs.
Ulnar Claw Hand
Bow-stringing
Dequervaine's Tenosynovities is....
Inflammation to the 1st compartment
These 2 ligament provide support to the radiocarpal and midcarpal joints
The medial and lateral collateral ligaments
What fingers are Dorsal Interossei acting on and how many on each finger? what action do they cause?
Index (1), Middle (2) and Ring (1). Abduction of the fingers
Ulnar nerve is injured. Weakness in forearm. Paresthesia in digits 4+5.
