Four-corner arthrodesis

The effect of lunate position on range of motion after a four-corner arthrodesis: A biomechanical simulation study

“…One of the surgical treatment options is the four-corner arthrodesis, where four carpal bones, i.e. lunate, capitate, triquetrum and hamate (LCTH), are fixed together and the scaphoid is excised from the wrist (Watson and Ballet, 1984;Cohen and Kozin, 2007;Shin, 2001;Kendall et al, 2005).…”

Management of Complications of Wrist Arthroplasty and Wrist Fusion

“…Thus, the use of Steinmann pins, Kirschner wires, screws and/or intramedullary rods have been advocated in these patients along with extensive synovectomy and ulnar head excision (53)(54)(55)(56). Similarly, the optimal construct for intercarpal fusions are less definitive, with variable results noted between pin and screw fixation versus circular compression plating (57)(58)(59).…”

“…Superficial infections occur far more frequently, with a rate of approximately 3%, versus deep infections at roughly 0.5% (46,48,57). Superficial infections often stem from wound issues, particularly caused by the thin skin that is present on the dorsum of the wrist in many patients (68) When deep infections occur, operative irrigation and debridement with removal of hardware is the treatment of choice, followed by a course of antibiotics tailored to cultures obtained from the site of infection (68).…”

Management of Scapholunate Advanced Collapse Pattern of Degenerative Arthritis of the Wrist

“…The average nonunion rate associated with use of pins, staples, or compression screws is approximately 3%. 12,13 The circular plate has been associated with a much higher nonunion rate of 26% 12 to 62%. 14 Claiming that the failures were technique dependent.…”
