Hand

Question 1

REVERSE OBLIQUE PROJECTION
_____ Recommendations
PP: Hand rotated 45o
internally
RP: 3rd MCP joint
CR: ┴
ER: To demonstrate severe metacarpal deformities
fractures

Answer 1

Lane-Kennedy-Kuschner

Question 2

TANGENTIAL OBLIQUE PROJECTION
____ Recommendation
PP: Hand in PA position; hand rotated 40-45o
toward ulnar surface & 40-45o
forward; MCP joints
flexed 75-80o
; hand dorsum resting on IR
RP: MCP joint of interest
CR: ┴
ER: To demonstrate metacarpal head fractures

Answer 2

Kallen

Question 3

PP: Hand in lateral position; digits extended; ulnar
aspect down (lateromedial projection); radial aspect
down (mediolateral projection; more difficult to
assume); thumb 90o
to palm
RP: 2
nd MCP joint
CR: ┴
SS: Lateral projection of the hand in extension
ER: To localize foreign bodies and metacarpal
fracture displacement

Answer 3

LATERAL PROJECTION
In Extension

Question 4

____ Position: Eliminates superimposition
of all phalanges (except proximal phalanges)

Answer 4

Fan Lateral

Question 5

___ METHOD
PP: Hand rotated 5o
posteriorly from true lateral
position (removes superimposition of 2nd
-4th
metacarpals); thumb extended;
RP: Midshaft of 5th metacarpal
CR: ┴
ER: To better demonstrate fractures of 5th
metacarpal

Answer 5

Lewis

Question 6

PP: Hand in natural arch position; digits relaxed
RP: 2
nd MCP joint
CR: ┴
SS: Lateral projection of the hand in flexion
ER: To demonstrate anterior or posterior
displacement in fractures of metacarpals

Answer 6

LATERAL PROJECTION
In Flexion

Question 7

____ METHOD
AP OBLIQUE PROJECTION
PP: Hand supinated; medial aspect against IR; 45o
sponge support
RP: b/n level of 5th MCP joints of both hands
CR: ┴
SS: AP oblique projection of both hands
ER: To diagnose rheumatoid arthritis
