Outcomes measurements after pollicization remains difficult due to the lack of a standardized assessment protocol. This study reports our experience of a global assessment of pollicized thumbs that includes a specific questionnaire for subjective evaluation, a detailed clinical assessment focused on functional outcomes incorporating function and usage of the pollicized thumb. Twenty-seven patients completed the questionnaire, and nine hands were clinically evaluated by a multidisciplinary team composed of hand surgeons and occupational therapists. Subjective evaluations revealed that 24 patients would recommend pollicization. Clinical evaluations revealed that only four out of nine patients properly integrated their pollicized thumb during bimanual activities; however, occupational therapy input allowed the children to compensate for the lack of strength and other difficulties. We propose the use of this global assessment package to analyse function and usage at various capacities, which can be useful for the surgeon, child and parents.Level of evidence: IV.
