The arthroscopic treatment of avascular necrosis of the proximal pole following scaphoid nonunion.

Journal Article (Journal Article)

The authors describe a technique of treating scaphoid nonunions with associated avascular necrosis consisting of arthroscopic resection of the distal pole of the scaphoid combined with radial styloidectomy. The results at 2-year follow-up showed all three patients to have complete relief of their mechanical pain and improvement in their range of motion as well as high satisfaction with the procedure. Modified Mayo Wrist Scores were a mean preoperatively of 60 and postoperatively of 88. Postoperative radiographs showed no increase in the scapholunate gap. However, the capitolunate angle increased from a mean of 3 degrees to 13 degrees . There was no progression of degenerative changes noted. The advantages of this technique include (1) minimal morbidity, (2) relief of mechanical pain, and (3) improved range of motion with no early degenerative changes. The rate and severity of degenerative change following this procedure remain unknown.
