Pollicisation of the index finger for absence or severe hypoplasia of the thumb has been reported as a good procedure to recreate a new "thumb" with good cosmesis and acceptable function. The purpose of this study is to evaluate the outcome of our series. Seventeen patients with 24 involved hands agreed to come back for evaluation. The mean age at operation was 12 months. In 8 hands there was a...
