We report functional and cosmetic outcomes in 14 patients (six bilateral and eight unilateral) with type IV radial longitudinal deficiency who underwent radialization. Follow-up ranged from 5 to 19 years. Outcome measures were grip and pinch strengths, Percival and Sykes score, Vilkki score, Cattaneo grading, and a questionnaire to patients. Radiological assessment included the hand-forearm angle, the hand-forearm position, and ulna length and width. At final follow-up, the length of the affected ulna was 56% of the length of the normal ulna. The distal ulna hypertrophied to 97% of the opposite distal radius and a median loss of correction of hand-forearm angle was 9°. All hands improved on Vilkki severity grade and on the Cattaneo functional and aesthetic grading. We conclude that radialization is an effective procedure in these cases, but secondary procedures may be required for the long-term maintenance of wrist alignment and hand function. Level of evidence: IV.
