- Discussion:
   - injury must occur to both interosseous and capsular ligaments for rotational instability of the scaphoid to occur;
   - dorsal approach to the wrist:
   - reduce scaphoid into the extended position;
          - surgeons gloved finger presses the distsal pole of scaphoid into an extended position;
          - K wire is inserted across the scapho-capitate interval while the scaphoid is held in the extended position;
   - reduce lunate out of DISI position;
          - K wire can be directly inserted into the lunate (dorsal to volar direction);
          - K wire is then pulled dorsally and angled superiorly (which brings the lunate into a reduced position)
   - scapholunate interval is reduced;
          - tenaculum clamp is used to directly compress the scapholunate interval;
          - K wire is inserted across the scapholunate and SC intervals;

   - bone anchors insertion:
          - bone anchors are inserted into the distal aspect of the scaphoid and lunate;
   - SL ligament is repaired:
   - capsulodesis augmentation is added if needed
