Mayfield classification of carpal instability (perilunate instability)

Mayfield classification of carpal instability, also known as perilunate instability classification (carpal dislocations), describes carpal ligament injuries.  Instability has been divided into four stages 1-2: stage I: scapholunate dissociation (rotatory subluxation of the scaphoid) disruptio...

Scaphoid fracture

Scaphoid fractures (i.e. fractures through the scaphoid bone) are common, in some instances can be difficult to diagnose, and can result in significant functional impairment. Epidemiology Scaphoid fractures account for 70-80% of all carpal bone fractures 1. Although they occur essentially at a...

Palmer classification of TFCC abnormalities

Palmer classification for triangular fibrocartilage complex (TFCC) abnormalities is based on the cause, location and degree of injury 1: Class 1 - traumatic injury a: central perforation b: ulnar avulsion with or without distal ulnar fracture may involve the proximal or distal lamina (foveal...

Chauffeur fracture

Chauffeur fractures (also known as Hutchinson fractures or backfire fractures) are intra-articular fractures of the radial styloid process. The radial styloid is within the fracture fragment, although the fragment can vary markedly in size. Pathology Mechanism These injuries are sustained eit...
Article

Dorsal intercalated segment instability

Dorsal intercalated segment instability (DISI) is one of the types of instability involving the wrist. It occurs because of a disruption of the dorsal intercarpal ligament. It is more often encountered than volar intercalated segment instability (VISI). Pathology Aetiology wrist trauma, with ...

Ulnar impaction syndrome

Ulnar impaction syndrome, also known as ulnar abutment or ulnocarpal loading, is a degenerative wrist condition caused by the ulnar head impacting upon the ulnar-sided carpus with the injury to the triangular fibrocartilage complex (TFCC). Epidemiology Ulnar impaction syndrome most commonly pr...
Article

Ulnar impingement syndrome

Ulnar impingement syndrome is a wrist condition caused by a shortened distal ulna impinging on the distal radius proximal to the sigmoid notch. The syndrome is distinct from ulnar impaction syndrome, which typically occurs due to a long ulna (positive ulnar variance) impacting upon the triangula...
Article

Ulnar styloid impaction syndrome

Ulnar styloid impaction syndrome refers to wrist pain due to a long ulnar styloid process impacting upon the triquetral bone. Pathology An unlar styloid >6mm in length is commonly regarded as being long. Impaction results in chondromalacia of the opposing articular surfaces, i.e. the proximal ...

Ulnar-sided wrist impaction and impingement syndromes

There are several distinct ulnar-sided wrist impaction and impingement syndromes. Underlying anatomical causes exist for each syndrome, however, repetitive or excessive use of the forearm and wrist can also contribute. ulnar impaction syndrome: positive ulnar variance ulnar impingement syndrom...
