Neonatal accessory digits: a survey of practice amongst paediatricians and hand surgeons in the United Kingdom.
OBJECTIVE
To describe the management of neonatal accessory digits, comparing views of paediatricians with those of hand surgeons, giving particular emphasis to the form of partial, ulnar duplication of the little finger (ulnar or postaxial polydactyly type B) which has a narrow pedicle.


METHODS
Postal questionnaire of management preference using three photographs of ulnar accessory digits of varying complexity.


RESULTS
The response rate was 64% in 234 paediatricians and 25% in 260 surgeons. All respondents would intervene in cases of ulnar polydactyly type B with a narrow pedicle: 79% of paediatricians but only 67% of hand surgeons would recommend referral of these cases for specialist assessment, the remainder advocating ligation by the paediatrician in the nursery. Paediatricians and neonatologists working in regional centres or with an on-site specialist service were more likely to refer. There was almost unanimous agreement on the management of the most complex case, but no general consensus on that of the simplest form.


CONCLUSIONS
There is uncertainty and inequality in initial treatment decisions for infants with all but the most complex of accessory digits. Despite published evidence that ligation gives satisfactory results, most respondents in this survey advocate specialist referral, with evidence that the availability of specialist services influences decision making.
