Distal Radial Fracture Flashcards
History questions for someone with suspected distal radial fracture
- Mechanism of fall
- Hand position when fall
- Pain - SQITARS
- PMH - RF for OP, previous #, rheumatological disease?
- DH - steroids, OTC, anticoags
- Social - smoker?
Most common 3 types of distal radial #
- Smiths
- Colles - most common
- Bartons
Deformity and mechanism seen in Colles vs Smiths #
Assessing NV status of hand
- Median - OK sign, touch radial surface of distal 2nd digit
- Ulnar - Pinch paper, look for froments sign, touch ulnar surface of 5th digit
- Radial - thumb extension against resistance, dorsal surface of 1st webspace
Deformity seen on Colles x-ray
- Dorsal angulation
- Decrease in volar tilt
What is measured on x-ray when diagnosing distal radial # and normal values?
- Volar tilt - 11-24 degrees (negative = dorsal angulation)
- Inclination - 19-25 degrees
- Radial height - 11-12mm
How is volar tilt measured?
- Lateral view
- Perpendicular to long axis of radius
- Tangent line along dorsal to palmar surface of radius
How is inclination measured of distal radius?
- PA view
- Line perpendicular to long axis of radius - along articular surface
- Another line drawn down from tip of styloid process (tip of radius)
- <15 = inclination for operative management
How is distal radius height measured?
- Distal ulna to styloid process space
- Often reduced in fractures
How does inclination, radial height and volar tilt aid management direction of distal radial#?
- Volar displaced # are unstable and often require open reduction and surgical fixation
- In over 65s, non-surgical management should be primary for dorsally displaced (unless NV compromise)
- Under 65s consider volar tilt, inclincation, radial height and intra-articular joint space
General management for distal radius #
- Traction and manipulation using local anaesthetic - haematoma block or Biers block (into vein with tourniquet on)
- THEN below the elbow backslab cast
- Rpt x-ray in one week: If significantly still displaced/unstable or radiocarpal distance >2mm - surgery (open reduction internal fixation)
What is used for ORIF?
- Locked volar plating
- K wires - Kirschner wire, these are recommended as they are cheaper and a quicker procedure with no difference in outcome
Acceptable values for post reduction volar tilt and inclination
- Radial length (>5mm)
- Radial angulation or tilt (< 15° dorsal or 20° volar)
- Radial inclination (>15°) are among the radiological markers for acceptable reduction
TEach me surgery diagnostic values for distal radial #
- Radial height less than 11mm
- Radial inclination less than 22 degrees
- Radial Volar tilt more than 11 degrees
Not sure about this compared to the other values I found
Complications of open reduction and internal fixation
- Infection
- Neurovascular injury
- Tendon rupture
- Stiffness
- Malunion/non-union
- Broken metal work
- Re-fracture
- Carpal tunnel
- Complex regional pain syndrome
- Anaesthetic risk
- PE/DVT
- Death
