ABSTRACT

Traumatic hand lesions resulting in amputation always represent a surgical challenge because they disrupt daily function. This occurs particularly in thumb lesions, since the latter acts as a stable strut for the pincer in activities requiring skill and as a radial clamp for the cylindrical grip. Repair techniques aimed at reducing sequelae of thumb amputation that consist of pollicization of the index finger have been described. The term pollicization is used to describe the technique to replace a traumatized or absent thumb with the index finger, and it also refers to the complete reconstruction of a first ray which is absent. This study intends to assess the results of pollicization using the index finger to reconstruct the thumb with Ezaki’s technique. Special considerations for the procedure include sufficient length to allow for opposition and an appropriate pronation and abduction position in relation with the other fingers, stability and mobility, as well as an adequate motor strength of the pincer and, finally, sensibility.
