[Shortening of the radius]

This procedure provides mainly a widening of the lunate cavity and removes excessive stress. The resection performed through a dorso-lateral approach must be 3 to 5 millimeters wide. From our 17 cases, 12 results were excellent, 2 good, 1 fair and 2 bad. This procedure is particularly indicated when the ulnar variance is important but may also be used when it is normal. It's quite justified when the lunate sharpe is normal but considering the excellent results obtained even when the lunate is deformed we have extended its indications except in cases of additional arthritis.
