Scapho-trapezio-trapezoid arthrodesis for carpal instabilities and kienböck’s disease

Surgical Principles Limited wrist arthrodesis between scaphoid, trapezium and trapezoid after resection of articular surfaces and autogenous cancellous bone grafting. Prevention of rotatory scaphoid subluxation and subsequent carpal collapse; prevention of early radiocarpal arthrosis due to joint surface incongruency and, rerouting of transmitted forces across the proximal carpal row away from the lunate.
