HANDS ALL X-RAY POSITIONS
HAND X-RAYS
PA HAND – This position done to visualize Fractures,
dislocations of the bones, congenital deformities, or other anomalies of hand
Collimation – to include entire hand and carpals bones. For finger
include distal tip of affected finer to proximal end of metacarpals bones
Centering point – entering hand at 3rd metacarpal
joint
Cassette size - - 24×30cm
Centering ray- perpendicular to the cassette
FFD- 100cm
Cassette orientation - portrait or depend on patient
Protection – gonads shielding is advisable
Position of patient – the patient should be seated at the
end of the table with legs parallel to the table end and affected limb on the
table and place affected hand finger palmer side down on cassette.
OBLIQUE HAND
OBLIQUE HAND - This position done to visualize Fractures,
dislocations of the bones, congenital deformities, or other anomalies of hand

include distal tip of affected finer to proximal end of metacarpals bones
Centering point – entering hand at 3rd metacarpal
joint
Centering ray- perpendicular to the cassette
Cassette size - - 24×30cm
FFD- 100cm
Cassette orientation - portrait or depend on patient
Protection – gonads shielding is advisable
Position of patient - the patient should be seated at the
end of the table with legs parallel to the table end and affected limb on the
table and place affected hand/ginger Palmer side on a 45° sponge/angle thumb side raised slightly.
LAETRAL HAND
LATERAL HAND - This position done to visualize Fractures,
dislocations of the bones, congenital deformities, or other anomalies of hand
Collimation – to include entire hand and carpals bones. For finger
include distal tip of affected finer to proximal end of metacarpals bones
Centering point – To enter hand metacarpal joint
Centering ray- perpendicular to the cassette
FFD- 100cm
Cassette size - - 24×30cm
Cassette orientation - portrait or depend on patient
Protection – gonads shielding is advisable
Position of patient - the patient should be seated at the
end of the table with legs parallel to the table end and place affected hand
with thumb raised, down on cassette. To properly visualize the phalanges the
fingers should be positioned in fan like arrangement as per pic above. This is
not require if the area of the interest is the metacarpal bones.
PA THUMB
PA THUMB - This position done to
visualize Fractures, dislocations of the bones, congenital deformities, or
other anomalies of thumb
Collimation – to include distal
thumb and distal carpal bones
Centering point –metacarpal
Centering ray- perpendicular to the
cassette
FFD- 100cm
Cassette orientation – all three
thumb images can fit on one film and pa image should be to the medial side of
the film
Protection – gonads shielding is
advisable
Cassette size - - 24×30cm
Position of patient - the patient
should be seated at the end of the table with legs parallel to the table end
and place affected limb on the table and
place hand in lateral position with little finger on cassette and laying thumb
so that it is parallel with the cassette. A sponge can be used to steady the
thumb if required.
