Elbow/Ulna/Radius Flashcards
What condition is likely the cause of these findings?
RA (bc bilateral)
- Extensive erosive changes are visualized at the ulnartrochlear and radiocapitellar joints with an associated complete loss of those joint spaces.
What condition is likely the cause of these findings?
What condition is likely the cause of these findings?
Olecranon bursitis
DDX for olecranon bursitis = RA, Trauma, Infection, Gout
What condition is likely the cause of these findings?
- Osteophytes present around the ulnartrochlear joint and at the radial head
- Subchondral sclerosis is present at the ulnatrochlear joint without visible joint space loss.
- An ossific density is noted at the anterior margin of the ulnatrochlear joint.
DX: OA/DJD
MC fracture in the elbow in adult =
Radial head
(2nd MC = Olecranon)
What condition is likely the cause of these findings?
Acute intra-articular comminuted fracture of the radial head (Chisel fracture)
MC elbow fracture in children =
Supracondylar fx

What condition is likely the cause of these findings?
What condition is likely the cause of these findings?
DX: Acute comminuted fracture of proximal ulna with associated dislocation of the proximal radius → this pattern of disruption is referred to as a Monteggia fracture dislocation
Angulated fx of proximal 1/3rd of ulna w/ radial head dislocation anterior & outward =
Monteggia fx
Fracture of radius at the junction of middle & distal 1/3rd & associated subluxation of distal ulna =
Galeazzi fx
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?
- “Dinner fork” deformity → distal radial fx w/ posterior angulation
- Acute comminuted transverse fracture of the distal radial metaphysis (Colles fracture)
- Acute transverse fracture with displacement of the ulnar styloid process
- Mild to moderate osteoporosis with small artery calcification is suggestive of either diabetes or hyperparathyroidism
What condition is likely the cause of these findings?
What condition is likely the cause of these findings?
Septic arthritis (monarticular joint inflammation)
What condition is likely the cause of these findings?
Aggressive process of bonel; most likely osteosarcoma other possibilities are ewings sarcoma and osteomyelitis.
What condition is likely the cause of these findings?
- Bilateral lateral bowing of the radius and ulna with marked shorting of the ulnas → resulted in a decreased carpal angle
- Two sessile exostosisare noted at the distal aspect of the ulna on the right
- Similar findings although not as clear in there morphology are present on the distal left ulna and bilateral radius.
DX: bilateral madelungs deformity secondary to hereditary multiple exostosis.
