Chauffeur's fracture, also known as Hutchinson fracture, is a type of intraarticular oblique fracture of the radial styloid process in the forearm. [1] The injury is typically caused by compression of the scaphoid bone of the hand against the styloid process of the distal radius. It can be caused by falling onto an outstretched hand.
Distal radius fractures typically occur with the wrist bent back from 60 to 90 degrees. [5] Radial styloid fracture would occur if the wrist is ulnar deviated and vice versa. If the wrist is bent back less, then proximal forearm fracture would occur, but if the bending back is more, then the carpal bones fracture would occur.
Breakage of the radius at the radial styloid is known as a Chauffeur's fracture; it is typically caused by compression of the scaphoid bone of the hand against the styloid. De Quervain syndrome causes pain over the styloid process of the radius.
The system that comes closest to directing treatment has been devised by Melone. This system breaks distal radius fractures down into 4 components: radial styloid, dorsal medial fragment, volar medial fragment, and radial shaft. The two medial fragments (which together create the lunate fossa) are grouped together as the medial complex. [8]
Wrist osteoarthritis is gradual loss of articular cartilage and hypertrophic bone changes (osteophytes). While in many joints this is part of normal aging (senescence), in the wrist osteoarthritis usually occurs over years to decades after scapholunate interosseous ligament rupture or an unhealed fracture of the scaphoid.
These ligaments arise from the distal radius medial border and insert on the ulna at two separate and distinct sites: the ulna styloid and the fovea (a groove that separates the ulnar styloid from the ulnar head). Each ligament consists of a superficial component and a deep component. The superficial components insert directly onto the ulna ...
A Colles' fracture is a type of fracture of the distal forearm in which the broken end of the radius is bent backwards. [2] Symptoms may include pain, swelling , deformity, and bruising . [ 2 ] Complications may include damage to the median nerve .
The radial collateral ligament (external lateral ligament, radial carpal collateral ligament) extends from the tip of the styloid process of the radius and attaches to the radial side of the scaphoid (formerly navicular bone of the hand), immediately adjacent to its proximal articular surface and some fibres extend to the lateral side of the trapezium (greater multangular bone).
