Index finger pollicisation for a congenital thumb hypoplasia and aplasia-surgical techniques

ABSTRACT

Thumb hypoplasia and aplasia are disabling congenital deformities and in the more severe cases [Grades IV and V] the only possibility is pollicisation Some Grade III hypoplasia cases are more severe with absence of the trapezio-metacarpal joint and most of the first metacarpal. These cases are best treated by amputation and pollicisation. The authors describe in detail pollicisation of the index and its pitfalls
