Sauve-Kapandji Procedure

Distal radioulnar joint (DRUJ) arthritis from degenerative joint disease (DJD), inflammatory disease, or trauma

No need to dissect the sixth extensor compartment from the ulnar head if the extensor carpi ulnaris (ECU) tendon is not subluxated.

Create an ulnar-based rectangular DRUJ capsular flap (Fig. 19-1).
Insert two parallel guide wires through the ulnar head into the radius across the DRUJ (Fig. 19-2).
Back up the guide pins into the ulnar head.
Prepare mating surfaces of the ulnar head and sigmoid notch down to cancellous bone (Fig. 19-3).
