Comparison of postoperative radiographic parameters between the groups.

	Group A † (n = 18)	Group B ‡ (n = 72)	p-Value	Cohen’s d
UV at 2 weeks after surgery	2.0 ± 2.4	0.4 ± 2.3	0.010 *	0.690
UV at last follow-up	2.6 ± 3.0	0.6 ± 2.2	0.007 *	0.842
ΔUV (mm)	0.6 ± 1.2	0.5 ± 1.0	0.225	0.096
RI (°) at last follow-up	21.7 ± 3.1	24.4 ± 3.7	0.055	0.752
RL (mm) at last follow-up	10.3 ± 1.6	11.4 ± 1.7	0.113	0.654
VT (°) at last follow-up	6.6 ± 7.6	8.9 ± 6.5	0.195	0.341

UV—ulnar variance; ΔUV (mm), last UV—postop 2 weeks UV; RI—radial inclination; RL—radial length; VT—volar tilt, ^† Group A, patients who had ulnar-sided sclerotic lesions of lunate; ^‡ Group B, patients who had no sclerotic lesion of lunate. * Statistically significant (p < 0.05).
