Wrist/Hand Flashcards
What condition is likely the cause of these findings?
- Loss of the distal interphalangeal joint spaces of all the digits is accompanied by subchondral sclerosis and osteophytes.
- Nonuniform loss of joint space is present at the 1stmetacarpal phalangeal joint.
- Diminished joint space visualized at the proximal interphalangeal joints of the 3rd and 4th digits.
DDX for affecting DIPS →
Nodules at distal interphalangeal joints = ____ nodes
Nodules at proximal interphalangeal joints = ____ nodes
Heberden
Bouchard
What condition is likely the cause of these findings?
Erosive osteoarthritis
What condition is likely the cause of these findings?
What condition is likely the cause of these findings?
DX: Psoriatic arthritis
- Distal interphalangeal joints narrowed at 2nd, 3rd, 4th and 5th digits on right and 2nd and 3rd digits on the left with associated small subchondral cysts.
- Marginal erosions are present at these same joints at the bases of the distal phalanges with associated adjacent periosteal reactions given the mouse ears appearance.
What condition is likely the cause of these findings?
Characteristics of ____ include:
- Predominate involvement of DIPs and PIPs with sparing of the metacarpal phalangeal and carpal jointso
- Involvement of all joints in a single digit → known as the ray pattern
- Asymmetric from side/side and digit/digit
- Marginal erosions with adjacent periostitis, “mouse ears”
- Whittling of phalanx, erosion into articular surface “pencil in cup”
- Can see sclerosis of distal phalange “ivory phalanx”
Psoriatic Arthritis

DX: Progressive systemic sclerosis
DDX for distal phalanx erosion: HPT, Psoriatic Arthritis, PSS
What condition is likely the cause of these findings?
RA
What condition is likely the cause of these findings?
RA
What condition is likely the cause of these findings?
(Normal on left; Often first sign of this disease process)
What condition is likely the cause of these findings?
Deposition arthritis → gout most likely
What condition is likely the cause of these findings?
What are the difference types of arthritis demonstrated here?
What condition is likely the cause of these findings?
- Transverse lucency is noted extending through the waist of the scaphoid. There is 100% apposition between fracture fragments with no angulation or rotation.
DX: Transverse non-comminuted fracture through the waist of the scaphoid
What condition is likely the cause of these findings?
What condition is likely the cause of these findings?
“Pie sign” of lunate on AP
DX: Lunate dislocation
What condition is likely the cause of these findings?
What condition is likely the cause of these findings?
What condition is likely the cause of these findings?
What condition is likely the cause of these findings?
- Anterior angulation of distal aspect of distal fragment
DX: Acute non-comminuted mid shaft fracture of the 5thdigit (bar-room fracture).
Fx that occurs at base of first metacarpal and can be intra-articular =
Bennett fx
What condition is likely the cause of these findings?
- Well defined lucency is noted in the base of the proximal 5th phalange; Medullary based with mild bony expansion. There is cortical disruption present. Subtle stippled calcification is visualized in the matrix.
DX: Enchondromais the most likely diagnosis with an associated pathological fracture
