Hof Radial Head

Front 1

Ipsilateral distal forearm and wrist should be examined witha radial head fracture. Tenderness to palation or stress at the DRUJ may indicate the presence of what lesion?

Back 1

Essex-Lopresti lesion

Front 2

What is an essex-lopresti lesion?

Back 2

Radial head fracture-dislocation with associated interosseous ligament and DRUJ disruption

Front 3

Besides AP and lateral, this view will provide visualization of the radiocapitellar articulation

Back 3

Greenspan view (beam angled 45 degrees cephalad)

Front 4

What is the classification scheme for radial head fractures?

Back 4

Mason classification

I: Nondisplaced
II: Marginal fx with displacement
III: Comminuted involving entire head
IV: A/w dislocation of elbow (Johnston)

Front 5

Which is more sensitive: Anterior or Posterior fat pad sign?

Back 5

Posterior

Front 6

Indications for surgery in an isolated partial radial head fracture

Back 6

1. Block to motion + Mason II
2. Displacement of large fragment >2 mm without a block to motion

Front 7

How are most radial head fractures treated?

Back 7

Nonoperatively

Front 8

What is the most common problem patients encounter after an isolated radial head fracture?

Back 8

Elbow stiffness

Front 9

What approach will you use to perform an ORIF of an isolated partial radial head fracture? What structures are at risk?

Back 9

Kocher exposure (Anconeus and ECU)

LCL, PIN

Front 10

What is a potential problem with radial head prosthesis?

Back 10

Oversizing the radial head implant and thus potentially "overstuffing" the joint
