Ulna
Radius
5 Metacarpal Bones
How many joints does the wrist have?
A. 14 Joints
B. 15 Joints
C. 16 Joints

D. 17 Joints
What are some symptoms of carpal tunnel syndrome?
- Paraesthesia and pain at night
- Gradual numbness of the fingers while driving
- Atrophy of the thenar muscles; decrease opposition
- Functionally: dropping items, difficulty buttoning shirt, impaired pinch and grip strength
Tests performed for carpal tunnel syndrome
- Tinel Sign
- Phalen Test
- Wrist Extension
- AROM and MMT
- Sensory Assessment
- Coordination Assessments
Tinel Sign
Tapping from proximal palmer crease to distal palmer crease, positive if parasthesia in the median nerve distribution
Phalen Test
Patient places dorsal aspects of hands together, maintains wrist flexion for 60 seconds
Wrist Extension
(testing for carpal tunnel syndrome)
Palms of hands together, extension for 60 seconds
AROM and MMT
(testing for carpal tunnel syndrome)
Oppenens pollicis
Sensory Assessment
(testing for carpal tunnel syndrome)
Decreased sensation through the median nerve distribution
Ligament in the wrist help maintain BLANK alignment.
Ligaments in the wrist help maintain intercarpal alignment.
What are wrist ligaments classified as?
Extrinsic or Intrinsic
Where do extrinsic ligaments attach in the wrist?
Extrinsic ligaments are proximally attached to the radius or ulna and attach distally within the wrist.
Where do intrinsic ligaments attach in the wrist?
Intrinsic ligaments both attach at the proximal and distal attachments within the wrist.
What are the extrinsic ligaments of the wrist?
Dorsal Radiocarpal
Radial Collateral
Palmer Radiocarpal
Triangular Fibrocartilage Complex (TFCC)
What does the triangular fibrocartilage complex (TFCC) support?
Supports at the distal radial ulnar joint
Holds the head of the ulna in the ulnar notch of the radius
Is a primary stabilizer of the distal radioulnar joint
TFCC Tear can result in
Painful clicking, decreased grip strength
Often mistaken for a radial fracture
What are the intrinsic ligaments of the hand?
Short Distal Row
Intermediate
Long
Where do the wrist flexors attach?
Attach at the medial epicondyle; Humerus
Where do wrist extensors attach?
Attach at the lateral epicondyle; humerus
Pollicis is the…

C. Thumb
D. None of the above
C. Thumb
True/False
Wrist Extensors stabilize the wrist when the forearm is pronated.
True
Tenodesis Grip
A passive hand grasp and release mechanism, affected by wrist extension or flexion
FOOSH stands for?
