Types of bone fractures upper extremity

Chauffer Fracture (Hutchinson’s Fracture)

Oblique fracture of radial styloid

Boxer’s Fracture

Transverse fracture of head of 5th metacarpal with palmar angulation

Reverse Barton’s Fracture

includes volar rim of radius while conventional Barton fracture involves dorsal rim

Essex Lopresti Fracture

comminuted fracture of head of radius, associated with dislocation of distal ulnar joint-like Galeazzi fracture but radial fracture is comminuted and involves head

Skier’s thumb (Gamekeeper’s break, dancer’s thumb)

Injury involves ulnar collateral ligament of MCP joint of thumb

Chisel Fracture

incomplete fracture of head of radius-fracture line extends distally from center of articular surface, approximately one-half inch-in adults, most common fracture of elbow involves either head or neck of the radius

Jones fracture

“true jones” fracture occurs 1” distal to base of 5th metacarpal

Bennett’s Fracture

intra-articular fracture of base of 1st metacarpal- fracture must involve 1st carpometacarpal joint

Colles fracture

transverse fracture of distal radial metaphysis proximal to joint with dorsal displacement and angulation of distal fragment

Smith Fracture

transverse fracture of distal radial metaphysis with palmar displacement of distal fracture fragment-

if intra-articular, called reverse Barton fracture

Galeazzi fracture

fracture of shaft of radius associated with dislocation of distal radioulnar joint

Mallet finger

Baseball finger describes a flexion deformity of distal interphalangeal joint cause by extensor tendon separation from distal phalanx

Monteggia fracture

proximal ulnar fracture with anterior dislocation of radial head-due to forceful pronation injury of forearm

barton’s fracture

intra-articular fracture of dorsal margin of distal radius-

fracture line is oblique and extends to the radiocarpal joint

Nursemaid’s elbow

dislocation of the radial head caused by forceful pull on the forearm-

line parallel to the long axis of the shaft of the radius should always intersect the capitellu
