Four Fractures of the Wrist

Four Fractures of the Wrist

Rolando Fracture
  • Comminuted
  • Intra-articular
  • Fracture through base of thumb
  • Prognosis: worse than Bennett's fracture
    (difficult to reduce)

 

Bennett's Fracture
  • Intra-articular fracture/dislocation of base of 1st metacarpal
  • Small fragment of 1st metacarpal continues to articulate with trapezium
  • Lateral retraction of 1st metacarpal shaft by abductor pollicis longus
     

Barton's Fracture
  • Intra-articular fracture of the dorsal margin of the distal radius
  • Extends into radio-carpal joint
     

Colles' Fracture
  • Extra-articular fracture of the distal radius
  • Does not extend into joint space
  • Dorsal angulation with radial and dorsal displacement of distal fragment
  • Frequently associated with fracture of ulnar styloid
