Proximal radius fracture

Question 1

Most sensitive test for Essex Lopresti

Answer 1

Tenderness at DRUJ

Rx : lateral view in pronation

Question 2

Essex Lopresti reduction of DRUJ

Answer 2

Supination then K Wire for 6 weeks

Question 3

Radial head fracture, typical mechanism

Answer 3

FOOSH with arm in pronation and elbow in extension

Question 4

Not isolated radial head fracture in (%)

Answer 4

30%
above all when valgus stress
- Essex-Lopresti
- Capitulum humeri
- ligamental injury

Question 5

Radial head resection vs radial head prosthesis

Answer 5

If ulnar ligament intact, can be excised (no luxation)
If radial head lfracture-dislocation (including Essex Lopresti), prosthesis (cave no silicone prosthesis for Essex-Lopresti)

Question 6

Radial head fracture, conservative if

Answer 6

• articular step not < 2mm

- subcapital with < 15°

Question 7

Radial Head Approach

Answer 7

Kocher aka lateral aka posterolateral approach between:

• Anconeus (radial n.)
• ECU (PIN)
  
  • incise supinator in pronation to move PIN away, stay posterior to avoid PIN lesion

Alternative : Kaplan

• ED
• ECRB/ECRL
• CAVE n.radialis

Question 8

Elbow terrible triad

Answer 8

Dislocation
Radial head fracture
Coronoid fracture
