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...
Article
Scapholunate dissociation
Scapholunate dissociation, also known as rotary subluxation of the scaphoid, refers to an abnormal orientation of the scaphoid relative to the lunate and implies severe injury to the scapholunate interosseous ligament and other stabilizing ligaments.
Carpal dissociation implies carpal instabili...
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...

Causes of abnormal lunate signal on MRI
There are several important causes of an abnormal lunate signal on MRI, the most frequent causes being Kienböck disease (25%), ulnar impaction syndrome (25%) and intraosseous ganglia (20%) 1. Appreciation of the pattern of bone signal change can often allow the correct diagnosis to be made.
