Upper limb: Distal Radial Fractures Flashcards
describe the mechanism by which distal radial fractures are usually sustained
fall onto outstretched hand(FOOSH)
what different types of distal radial fractures can occur
Colles, Smith’s, Barton’s or comminute intra-articular fractures
describe what a Colles fracture is
extra-articular fracture of distal radius within an inch of the articular surface and with dorsal displacement on angulation
what does treatment of Colles fracture depend on
degree of displacement angulation, presence of dorsal communication and functional demand of patient
which Colles fractures tend to have a better outcome in terms of pain, ROM, grip strength and function
fractures which heal with less angulation and shortening
how may minimally displaced or undisplaced Colles fractures be treated
with splintage alone
describe how displaced/angulated Colles fractures are treated
plaster cast, or if unstable after reduction/ORIF can be used to pin distal fragment in place
what neurovascular injuries can be associated with Colles fracture
median nerve compression from stretch of the nerve or bleed into the carpal tunnel
describe what a Smith’s fracture is
a volarly displace or angulated extra-articular fracture of the distal radius
which mechanism is usually the cause of a Smith’s fracture
falling onto back of flexed wrist
what treatment should all Smith’s fractures receive and why
ORIF using plate and screws because they are highly unstable injuries
describe what a Barton’s fracture is
intra-articular fractures of distal radius involving dorsal or volar rim, where the carpal bones pf wrist sublux with displaced rim fragment
what treatment is required for Barton’s fracture
ORIF
what does ORIF mean
open reduction and internal fixation
what may cause a comminuted intra-articular distal radial fracture
high energy trauma or very poor bone quality
