Fracture with a dorsal tilt. Dorsal is left, and volar is right in the image. There are a number of ways to classify distal radius fractures.Classifications systems are devised to describe patterns of injury which will behave in predictable ways, to distinguish between conditions which have different outcomes or which need different treatments.
It is an intra-articular fracture of the distal radius with dislocation of the radiocarpal joint. [2] There exist two types of Barton's fracture – dorsal [3] and palmar, the latter being more common. The Barton's fracture is caused by a fall on an extended and pronated wrist increasing carpal
Another line perpendicular to the longitudinal axis of the radius is drawn. The angle between the two lines is the angle of volar or dorsal tilt of the wrist. Measurement of volar or dorsal tilt should be made in true lateral view of the wrist because pronation of the forearm reduces the volar tilt and supination increases it. When dorsal tilt ...
A Smith's fracture, is a fracture of the distal radius. [1] Although it can also be caused by a direct blow to the dorsal forearm [2] or by a fall with the wrist flexed, the most common mechanism of injury for Smith's fracture occurs in a palmar fall with the wrist joint slightly dorsiflexed. [3] Smith's fractures are less common than Colles ...
The scapholunate ligament is an intraarticular ligament binding the scaphoid and lunate bones of the wrist together. It is divided into three areas, dorsal, proximal and palmar, with the dorsal segment being the strongest part. [3] It is the main stabilizer of the scaphoid. In contrast to the scapholunate ligament, the lunotriquetral ligament ...
The distal part of the palmar ligament, called the palmar plate, is 2 to 3 millimetres (0.079 to 0.118 in) thick and has a fibrocartilaginous structure. The presence of chondroitin and keratan sulfate in the dorsal and palmar plates is important in resisting compression forces against the condyles of the proximal phalanx. Together these ...
The volar forearm splint is best for temporary immobilization of forearm, wrist and hand fractures, including Colles fracture. [ citation needed ] There are several established instability criteria: [ citation needed ] dorsal tilt >20°, comminuted fracture, abruption of the ulnar styloid process, intraarticular displacement >1mm, loss of ...
Lister's tubercle is used as a useful landmark during wrist arthroscopy and other wrist surgery. [1] [6] It is palpable on the dorsum of the wrist. [1] It is often difficult to clearly distinguish with radiography. [1] Hyperextension of the wrist can lead to fracture of Lister's tubercle, as pressure is increased from the extensor pollicis ...
