Limited triscaphoid intercarpal arthrodesis for rotatory subluxation of the scaphoid

Triscaphoid arthrodesis and its complications

Carpal instability and/or arthrosis of the scaphotrapezial joint were treated with scaphotrapezio-trapezoid arthrodesis in 19 hands. Healing failed primarily in five hands as determined by conventional or computed tomography. No correlation was found to surgical methods or immobilization time. Surgical revision had to be done for four of the nonunions. These complications do not correspond to those described in the literature but draw attention to some adversities encountered in the use of this method.
