Patients in the antegrade group achieved better outcomes than patients in the retrograde group for all clinical parameters at 3 months postoperatively ( ROM : antegrade median 80 [ range , 57-90 ] versus retrograde 69 [ range , 45-90 ] , difference of medians 11 , p < 0.001 ; VAS : antegrade median of 2 [ range , 0-5 ] versus retrograde 4 [ range , 0-7 ] , difference of medians 2 , p < 0.001 ; grip strength : antegrade median 81 % [ range , 60 % -100 % ] versus retrograde 71 % [ range , 49 % -98 % ] , differences of medians 10 % , p < 0.001 ; DASH : antegrade median 4.3 [ range , 0-15 .8 ] versus retrograde 10.3 [ range , 0-28 .4 ] , difference of medians 6 , p < 0.001 ) , but these differences , with the numbers available , were not observed at 6 months postoperatively for any clinical parameters ( ROM : antegrade median 88 [ range , 81-90 ] versus retrograde 87 [ range , 80-90 ] , difference of medians 1 , p = 0.35 ; VAS : antegrade median 1 [ range , 0-2 ] versus retrograde 1 [ range , 0-3 ] , difference of medians 0 , p = 0.67 ; grip strength : antegrade median 93 % [ range , 78 % -104 % ] versus retrograde 91 % [ range , 76 % -101 % ] , difference of medians 2 % , p = 0.41 ; DASH : antegrade median 3 [ range , 0-12 .5 ] versus retrograde of 4.3 [ range , 0-15 .8 ] , difference of medians 1.3 , p = 0.48 ) .
