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...

De Quervain tenosynovitis

De Quervain tenosynovitis, also known as washerwoman's sprain/strain, is a painful stenosing tenosynovitis involving the first extensor (dorsal) tendon compartment of the wrist (typically at the radial styloid). This compartment contains the abductor pollicis longus (APL) and extensor pollicis b...

Perilunate dislocation

Perilunate dislocations and perilunate fracture dislocations are potentially devastating closed wrist injuries that are often missed on initial imaging.  These injuries involve dislocation of the carpus relative to the lunate which remains in normal alignment with the distal radius. They should...
Article

Lunate dislocation

Lunate dislocations are an uncommon traumatic wrist injury that require prompt management and surgical repair. The lunate is displaced and rotated volarly. The rest of the carpal bones are in a normal anatomic position in relation to the radius. These should not be confused with perilunate disl...

Scapholunate dissociation

Scapholunate dissociation represents a significant ligamentous wrist injury that is important to identify on imaging. There is disruption of the scapholunate ligament with resultant instability. The condition may also be known as rotary subluxation of the scaphoid. Epidemiology Scapholunate di...
Article

Terry Thomas sign

The Terry Thomas sign refers to an increase in the scapholunate space on an AP radiograph of the wrist (or coronal CT). The increased distance indicates scapholunate dissociation (often with rotary subluxation of the scaphoid) due to ligamentous injury. There is no consensus as to what measureme...

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...
