We describe a modification of the technique for arthrodesis of the joints between the scaphoid, the trapezoid and the trapezium (the S-T-T joint) described by Sandow, that involves the en bloc resection of a cylinder of bone incorporating a portion of each of the scaphoid, trapezoid and the trapezium, using a hollow mill, and replacing it with a cylindrical graft of exactly the same size taken from the distal radius. The procedure is relatively quick and easy with a high rate of fusion and must be regarded as a preferable alternative to other, more complex procedures.
