Does the "three-ligament tenodesis" procedure restore carpal architecture in static chronic scapholunate dissociation?

The effect of the three-ligament tenodesis on the scapholunate angle and scapholunate gap was studied. A comparison was made between these angles preoperatively and postoperatively in 12 patients. There was a significant decrease in the scapholunate angle from 77 to 68 degrees, and the scapholunate gap was reduced from 4.25 mm to 3.29 mm. We also studied the correlation between scapholunate angle and scapholunate gap postoperatively in a cohort of 25 patients and found a significant correlation. This suggests that the principle of the procedure is correct, but the aims are not fully achieved, and that the procedure has a similar effect on SL gap and SL angle.
