Upper limb fractures Flashcards
How do scaphoid fractures typically occur?
FOOSH (fall onto outstretched hand)
Contact sports
What is the presentation of a scaphoid fracture?
Pain along the radial aspect of the wrist, at the base of the thumb
Loss of grip/pinch strength
What are the signs of scaphoid fracture on examination?
Tenderness over the anatomical snuffbox
Wrist joint effusion
Pain elicited by telescoping of the thumb
Pain on ulnar deviation of the wrist
What initial investigations are used to diagnose scaphoid fracture?
Plain film radiographs of the wrist in anterior-posterior view and lateral view
What further investigations may be used to diagnose scaphoid fracture?
CT scan can give a more detailed view of the wrist bones if XR is inconclusive
What is the initial management of a scaphoid fracture?
Immobilisation with futuro splint or standard below-elbow backslab
Referral to orthopaedics
What is the orthopaedic management of a scaphoid fracture?
Undisplaced fracture

- Surgical fixation
Proximal scaphoid pole fracture
- Requires surgical fixation
What are the complications of scaphoid fracture?
Non-union - can lead to pain and early osteoarthritis
Avascular necrosis
What is the blood supply to the scaphoid bone?
Retrograde blood supply - blood vessels supply the bone from only one direction
