Barton f.: an intraarticular fracture of the dorsal rim of the distal radius, usually resulting in subluxation of the radial carpal joint with the fracture site fragment.
chauffeur's f.: oblique fracture of the radial styloid caused by a twisting- or snapping-type injury; also called backfire f., Hutchinson f., and lorry driver's f.
chisel f.: incomplete, usually involving medial head of radius, with fracture line extending distally.
Colles f.: named prior to x-ray technology; implies a fracture of the distal radius, either articular or non-articular, with dorsal angulation of the distal fragment producing a silver fork deformity; generally associated with a fracture of the ulnar styloid.
Corner f.: a small bucket-handle-appearing fracture in the distal metaphyseal corner in a young child, often associated with child abuse.
de Quervain f.: combination of a wrist scaphoid fracture with volar dislocation of scaphoid fragment and lunate.
die-punch f.: an intraarticular fracture of the ulnar (volar) portion of the distal radius, usually caused by direct impaction of the lunate onto the lunate fossa of the distal radius.
Essex-Lopresti f.: a comminuted ¹radial head fracture with an injury to the ²distal radioulnar joint caused by disruption of the ³interosseous membrane, which can cause a proximal migration of the radius if the radial head is excised secondarily.
Galeazzi f.: typically a displaced fracture of the distal third or quarter of the radius with disruption of the distal radioulnar joint; called fracture of necessity because surgical fixation is required for reduction; also called a reverse Monteggia f., Dupuytren f., or Piedmont f.
Kocher f.: fracture of capitellum of distal humerus with possible displacement of fragment into joint.
Laugier f.: isolated fracture of the trochlea of the humerus at the elbow.
lead pipe f: typically in the forearm, a combination of greenstick fracture and torus fracture in the immature skeleton. Such fractures do not penetrate the entire shaft of the bone and have the appearance of a slightly bent lead pipe.
Lenteneur's f.: a distal radial fracture of the palmar rim, similar to Smith's type II fracture.
Monteggia f.: isolated fracture of proximal third of ulna, with anterior or posterior or lateral dislocation of radial head allowing angulation and overriding of ulnar fragments.
Moore f.: like a Colles f.; specifically, fracture of distal radius with dorsal displacement of ulnar styloid and impingement under annular ligament.
Mouchet f.: involves humeral capitellum.
Nightstick f.: undisplaced fracture of the ulnar shaft caused by a direct blow.
Piedmont f.: oblique f. usually at the proximal portion of distal third of the radius; obliquity runs from proximal ulnar to distal radial aspect, allowing distal fragments to be pulled into the ulna by the pronator quadratus muscle; fracture of necessity requiring
operative management.
Radial head f.: involves the most proximal part of the radius, a dish-shaped portion of bone.
radial styloid f.: involves distal radial tip of radius.
reverse Barton f.: dorsal displacement of carpus on radius, with associated fracture of dorsal articular surface of radius. The mechanism and appearance of this fracture are similar to those of a Colles f.
Skillern f.: open f. of distal radius associated with greenstick f. of distal ulna.
Smith f.: fracture of the distal radius in which the distal fragment is displaced volarly; also called reverse Colles f. This fracture was defined before the advent of radiography, and, classically, there are three types:
•Nonarticular
•Intraarticular; also called volar Barton f.
•Oblique nonarticular fracture near the joint line.
