CEN REVIEW QUESTION SET WITH
ACCURATE ANSWERS
◉ What is the 'mirror image' of a Monteggia fracture?
Answer: A Galeazzi fracture-dislocation.
◉ What happens to the radius and ulna in a Galeazzi fracture?
Answer: The radial shaft fractures while the ulna dislocates at the
wrist.
◉ What is a Colles' fracture?
Answer: A break in the distal radius occurring within 2.5 cm of
the wrist joint.
◉ What is the common mechanism of injury for a Colles' fracture?
Answer: A fall onto an outstretched, pronated hand (FOOSH
injury).
◉ What is the characteristic deformity associated with a Colles'
fracture?
Answer: The 'dinner-fork deformity'.
◉ What are the radiographic findings of a Colles' fracture?
,Answer: Dorsal displacement, impaction, altered articular tilt, and
associated ulnar injury.
◉ What does dorsal angulation in a Colles' fracture indicate?
Answer: A backward tilt of 10° or more on a lateral view may
guide surgical manipulation.
◉ What does the 'dinner-fork deformity' resemble?
Answer: The curve of an overturned fork.
◉ What is a Galeazzi fracture-dislocation?
Answer: A complex forearm injury involving a fracture of the
radial shaft and dislocation of the distal radio-ulnar joint.
◉ How should radiographs be taken for a Galeazzi fracture?
Answer: They must include the entire length of the radius and
ulna, and both elbow and wrist joints in two projections.
◉ What happens to the ulna in a Galeazzi fracture?
Answer: The distal end of the ulna dislocates due to the
shortening of the fractured radius.
◉ What are the four cardinal symptoms of a significant knee
injury?
Answer: Pain, swelling, giving way, and locking.
, ◉ What might patients report at the moment of a knee injury?
Answer: Hearing or feeling a 'pop' or 'crack', indicating a complete
ligament rupture.
◉ What is the role of the interosseous membrane in the forearm?
Answer: It acts as a connector between the radius and ulna,
holding them together.
◉ What happens to the radius and ulna when one bone fractures?
Answer: The other bone or the ligaments binding them together
are often also injured.
◉ What is the clinical presentation of a Colles' fracture?
Answer: Obvious deformity, severe pain, and tenderness localized
to the distal radius.
◉ What is the pediatric presentation of a Colles' fracture?
Answer: An angulated fracture of the distal radius or an
epiphyseal fracture.
◉ What is the significance of the ulnar styloid in a Colles'
fracture?
Answer: It is frequently avulsed by the triangular fibro-cartilage
during the injury.
