CHT Exam Prep – Wrist UPDATED ACTUAL Exam Questions
and CORRECT Answers
Which ligament is known as a ligament of a Testut? Describe it. - !@#$%%%%%
(ANSWERS)The
radioscapholunate ligament. %%%%%%
More appropriate classified as a "mesocapsule," relatively weak, lacks collagen bundles, but
has more vascular and neural tissues than other ligaments. Part of the extrinsic ligamentous
system.
Which carpal bone acts as a sesamoid bone? Which tendon inserts on it? - (ANSWERS)The
Pisiform. The FCU inserts onto it.
Which area of the wrist has ligaments rich in nerve endings, important for proprioception and
neuromuscular control? - (ANSWERS)The Triquetrum.
Note - the radial column has less innervation, but is important for mechanical stability.
What is the TFCC load test? - (ANSWERS)Ulnarly deviate the patient's wrist and move the prox
carpal row in a volar/dorsal direction with gentle manual compression over the TFCC.
What is the major stabilizer of the DRUJ? - (ANSWERS)TFCC
Piano key test - (ANSWERS)stabilize radius with one hand- with 2nd hand press volarly on ulna
and then dorsally- test in BOTH pronation and supination, compare to other side
+ = "spring back" reaction of the ulna
+ = DRUJ instability
What is a coalition? - (ANSWERS)an incomplete separation of the embryological cartilage. One
large bone appears without an articulation bet two bones. A lunotriquetral coalition usually
does not affect ROM and is usually asymptomatic.
Scaphoid Shift Test - (ANSWERS)AKA Watson test. To perform the test, the examiner grasps the
wrist with their thumb over the scaphoid tubercle (volar aspect of the palm) in order to prevent
the scaphoid from moving into its more vertically oriented position in radial deviation. For the
test, the wrist needs to be in slight extension. The patient's wrist is then moved from ulnar to
radial deviation. The examiner will feel a significant 'clunk' and the patient will experience pain
if the test is positive.
Mild diagnostic value for ligament injury of the SLL.
Can have 30% false positive with laxity in the wrist.
