Wrist fractures

March 2018 | by EMauthor


Colles fracture


Fracture within 2.5 cm of articular surface with a combination of deformities (dorsal shift and tilt, radial shift and tilt, and impaction)

Check radial pulse and median nerve function

Minimally displaced fractures

oBelow elbow back slab

oAnalgesia

oFracture clinic follow up

oWill need manipulation if articular surface of radius is angulated more than 10 deg or if there is significant shortening

Place in a below elbow back slab with mild flexion and ulnar deviation

Arrange a fracture clinic follow up

Comminuted or unstable fractures, especially in young adults, will need internal fixation, refer to orthopaedics


Smith fracture (reverse Colles)


Volar angulation of distal radius

Unstable fracture, will need a buttress plate in many cases

ED manipulation is essentially a reverse of the Colles manipulation finished off with a volar slab in dorsal angulation.  Orthopaedic team must review patient in the department (and will usually ambulate them; but they cannot be referred by ED to fracture clinic)


Barton fracture


A variant of Smith fracture with involvement of the articular surface

Unstable fractures that need internal fixation

Refer to orthopaedics


Scaphoid fracture


Can result from a fall on outstretched hand or kick back injury

Clinically suspected from mechanism of injury and tenderness over the anatomical snuff box and tenderness over dorsal surface of scaphoid (which is more specific )

Other clinical signs include pain on telescoping the thumb and pain on ulnar deviation of the wrist

Ask for scaphoid views

If obvious fracture identified, then

oScaphoid plaster

oAnalgesia

oFracture clinic follow up

If x-ray negative but clinically suspected then

oScaphoid plaster

oAnalgesia

oED review clinic in 10-14 days with plaster removal on arrival

Beware that fracture of radial styloid and  of the base of thumb metacarpal can give ASB tenderness


Avulsion fracture of triquetral


Commonly missed

Local tenderness over the triquetral

Look for the avulsed part on lateral view of the wrist

Treat with bandage and mobilisation or back slab if too painful

Refer to fracture clinic


Fracture of hook of hamate


Can be a sports injury

Tenderness over the hamate (ulnar side of wrist)

Will need special views, ask for senior help or bring to review clinic if in doubt


 Key point: triquetal and hook of hamate fractures are rare and are therefore missed more frequently.  Have a low threshold for seeking advice


Lower radial fracture in children  


Undisplaced fractures of the distal radial metaphysis, Greenstick/Buckle fractures.

oBelow elbow back slab

oAnalgesia

oFracture clinic

oAngulated fractures of lower radial metaphysis

oThose will need manipulation even if greenstick, refer to orthopaedics

Slipped radial epiphysis

oUsually of Salter-Harris 2 type

oRefer to orthopaedic or discuss with senior as they need prompt manipulation and plaster immobilisation
