Deck 13: Splinting Applications

Question 1

Extreme ulnar deviation results in:

A) a biomechanical block of wrist extension.
B) shortening of the ulnar deviators.
C) shifting of both rows of carnal bones.
D) all of the above.

Answer 1

D

Question 2

In terms of biomechanical considerations,the firm cone should be placed with the small end in the _____ side of the palm.

A) radial
B) ulnar

Answer 2

B
This position is consistent with the biomechanics of the ulnar side of the hand.

Question 3

The following arch supports a cylindrical grasp:

A) transverse.
B) longitudinal.
C) oblique.
D) palmar.

Answer 3

B
This arch includes the carpometacarpophalangeal arches.These arches are formed for each finger by the corresponding metacarpal bones and phalanges.The arches are concave on the palmar surface;the "keystone" of each arch lies at the level of the metacarpophalangeal joint.In its simplest form,this arch supports a basic cylindrical grasp.If the arches are expanded,the hand is longer.This arch allows the palm to flatten and cup itself around objects.

Question 4

The most effective method to lengthen soft tissue is:

A) high load brief stretch.
B) passive range of motion (ROM).
C) low-load prolonged stretch.
D) joint mobilization.

Question 5

Digit platforms should only be used:

A) at night.
B) when proximal realignment does not relax the digits.
C) when the digits are at risk for contracture.
D) all of the above.

Question 6

The hand-based thumb abduction splint is applied for:

A) functional activities.
B) immobilization.
C) inhibition of thumb adduction.
D) contracture prevention.

Question 7

At rest,the second metacarpal is aligned:

A) with the ulna.
B) with the radius.
C) midline between the radius and ulna.
D) with the carpal arch.

Question 8

The concept of dual obliquity states that objects held in the hand assume _____ oblique angle(s).

A) 1.
B) 2.
C) 3.
D) 4.

Question 9

The suggested splint for a proximal interphalangeal contracture is a _____ splint.

A) serpentine
B) tone and positioning
C) belly gutter
D) resting

Question 10

The literature reviewing dorsal- and volar-based splinting is:

A) supportive of dorsal-based splints.
B) supportive of volar-based splints.
C) inconclusive.
D) not in support of splinting at all.

Question 11

Proper palmar support implies that the:

A) third metacarpal head is superior to the other metacarpal heads.
B) splint progresses beyond the distal palmar crease.
C) first metacarpal is supported.
D) all of the above.

Question 12

The effectiveness of the inflatable pressure splint has:

A) not been proven.
B) been proven related to inhibition of spasticity.
C) been proven related to increasing functional use of the upper extremity.
D) been proven regarding contracture prevention.

Question 13

The collateral ligaments are lengthened by:

A) digit extension.
B) digit flexion.
C) application of resting splints.
D) thumb opposition.

Question 14

Loss of distal interphalangeal joint flexion may be due to:

A) oblique retinacular ligament contracture.
B) joint contracture.
C) both a and b.
D) none of the above.
