Q

For wrist that cannot be extended to w/in 15o of vertical
CR aligned // to palmar surface
Angled an additional 15o toward the palm

Mcquillen Martensen Suggestion

:GAYNOR-HART METHOD
TANGENTIAL PROJECTION

25
Q

PP: Dorsiflex the wrist; lean forward (to place carpal canal tangent to IR)
RP: Midpoint of the wrist
CR: ┴
SS: Carpal canal/tunnel
ER: Taken when patient cannot assume/maintain Gaynor-Hart Method

SUPEROINFERIOR PROJECTION

26
Q

For limited dorsiflexion of the wrist
Placed 45o sponge under palmar surface of the hand
Slightly elevates the wrist to place the carpal canal tangent to CR
With slight degree of magnification due to increased OID
