Question 4

Monteggia Fractures

Answer 4

I: Cranial lux of radial head with cranioproximal angulation of ulna fx

II: Caudal luxation of radius with caudal angulation of ulna

III: Lateral lux of radius

IV: Fx of proximal R/U with cranial lux of the radius

Question 5

Accessory Carpal bone fractures

Answer 5

I: avulsion fracture of the distal margin of the articular surface at the attachment of the ligament from accessory carpal bone to the ulnar carpal bone

II: proximal margin of the articular surface of the accessory carpal bone at the attachment of the ligaments that connect the accessory carpal bone to the distal radius and ulna

III: avulsion at the distal surface at the palmar end of the accessory carpal bone

IV: avulsion at the tendon instertion of the flexor carpi ulnaris muscle at the caudoproximal surface

V: Comminuted
