Outcomes of index finger pollicization in children using a modification of the Kozin, Mennen and Al-Qattan techniques

Our technique of pollicization incorporates that described by Kozin with modifications by Mennen and Al-Qattan. We studied the outcome of this technique using three different outcome scores. In total, 16 index finger pollicizations were assessed by the Reach Out! score, the Percival score and the Thumb Grasp and Pinch Assessment score. The mean Reach Out! score was 16 and the mean Percival and Thumb Grasp and Pinch Assessment scores were 18 and 43 respectively. Patients with radial longitudinal deficiencies had worse outcomes on the Percival score. The Blauth classification of thumb hypoplasia had no significant effect on the outcome scores. The three scores correlated well with each other. The age at pollicization showed a significant correlation with the Thumb Grasp and Pinch Assessment and Percival scores. The outcomes of our technique were good and similar to other techniques.<b>Level of evidence:</b> IV.
