Degenerative disorders of the wrist

Rotatory subluxation of the scaphoid in Kienböck’s disease is not a cause of scapholunate advanced collapse (SLAC) in the wrist

“…None of their previous studies, however, and no other reports have included patients with SLAC secondary to Kienböck's disease, [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] and there remains some doubt as to whether Kienböck's disease leads to SLAC wrist. We have investigated the long-term outcome of the conservative treatment of patients with Kienböck's disease associated with rotatory subluxation of the scaphoid.…”

“…This particular pattern of osteoarthritis of the wrist has become an established disorder. [1][2][3][4][5][6][7][8][9] They noted that the most common cause of SLAC wrist was rotatory subluxation of the scaphoid due to scapholunate dissociation and that it could also be secondary to nonunion of a fracture of the scaphoid, Kienböck's disease, fracture of the distal radius, Preiser's disease, and deposition of crystals of calcium pyrophosphate dihydrate. [4][5][6][7][8][9] They emphasised the need to avoid the development of SLAC secondary to rotatory subluxation of the scaphoid which accompanies advanced Kienböck's disease, [10][11][12][13] and advocated scaphotrapeziotrapezoid (STT) arthrodesis to prevent its inevitable development.…”

Die mediokarpale Teilarthrodese mit Entfernung des Skaphoids zur Behandlung des fortgeschrittenen karpalen Kollapses

“…Das Silikonmaterial war der starken Beanspruchung des Skaphoids jedoch nicht gewachsen, so dass durch Abrieb eine Silikonsynovialitis ausgelöst wurde. Zur Entlastung des Skaphoids wurde daraufhin die zentrale Säule des Handgelenks in Form einer kapitolunären Arthrodese stabilisiert, später zum besseren Durchbau die Arthrodese von Hamatum und Triquetrum hinzugefügt [9].…”

“…To decrease the pressure on the scaphoid, the central column of the wrist was stabilized by a capitolunate arthrodesis. Later on, an arthrodesis between hamate and triquetrum was added to achieve better consolidation [9].…”

Resection of the proximal row of the carpus. A review of 45 cases

“…Watson's classification [32] is used to define the stages of carpal instability associated with degenerative arthritis. He considered the scapho-lunate advanced collapse (SLAC) wrist to have three stages: Grade I Degenerative arthritis between the scaphoid and the radial styloid; Grade II Degenerative radio-scaphoid arthritis; Grade III Degenerative radio-scaphoid arthritis with osteoarthritic lesions between the head of the capitate and the lunate.…”
