From: Relationship between distal radius fracture malunion and arm-related disability: A prospective population-based cohort study with 1-year follow-up

Variables Relative risk
(95% CI)
p-value
Malunion*:   
   Malunion I 2.5 (1.08 - 5.8) 0.033
   Malunion II 3.7 (1.5 - 9.1) 0.004
Age (year) 1.02 (1.00 - 1.03) 0.082
Sex (male) 0.43 (0.21 - 0.88) 0.020
Fracture AO type (A) 1.13 (0.75 - 1.7) 0.563

  1. *No malunion, dorsal tilt ≤ 10° and ulnar variance ≤ 0 mm; Malunion I, dorsal tilt > 10° or ulnar variance ≥ 1 mm; Malunion II (combined malunion), dorsal tilt > 10° and ulnar variance ≥ 1 mm
