title: Pollicization of the index finger requiring secondary fusion of the new metacarpophalangeal joint.
abstract: In children with absent thumbs, some authors have stated that 'relative' contraindications of pollicization include severe fixed flexion contracture and instability of the proximal interphalangeal joint of the index finger. The current author does not consider severe proximal interphalangeal joint deformities of the index finger as a contraindication to pollicization; and hence these children are offered the procedure. A literature review did not reveal any study that specifically documents the outcome of pollicization in these cases. The current series included five children: four with severe (over 80°) fixed flexion contracture of the proximal interphalangeal joint of the index finger and one with instability of the proximal interphalangeal joint. All children were initially assessed during infancy at their local hospitals and the parents were informed that a pollicization procedure would yield a poor outcome. Presentation to the author was relatively late at a mean of 9.3 years (range 2.5-12). All children underwent two surgical procedures: a pollicization followed by fusion of the new metacarpophalangeal joint. The overall early functional outcome was good and all children/parents were satisfied with the procedure. These encouraging results warrant a prospective long term study on various conditions that are considered as 'relative' contraindications to the pollicization procedure.Level evidence: IV Therapeutic (case series).
