Abstract

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°, 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.
