Postaxial Type-B Polydactyly. Prevalence and Treatment*†

  title={Postaxial Type-B Polydactyly. Prevalence and Treatment*†},
  author={Brent Thomas Watson and William L. Hennrikus},
  journal={The Journal of Bone \& Joint Surgery},
A prospective screening program of 11,161 newborns identified twenty-one infants who had postaxial type-B polydactyly (a prevalence of one in 531 live births). Sixteen infants (76 per cent) had bilateral postaxial type-B polydactyly. Eighteen infants (86 per cent) had a family history of the anomaly. The racial prevalence was one in 143 live births of black infants and one in 1339 live births of white infants. The duplicated small fingers were treated in the newborn nursery with suture ligation…

Postaxial Type B Polydactyly Treated by Excision in the Neonatal Nursery

For infants with postaxial type B polydactyly, excision of the extra digit in the neonatal nursery is a safe and simple procedure with a good clinical and cosmetic outcome.

Office-Based Post–Axial Polydactyly Excision in Neonates, Infants, and Children

A case series of successfully performed in-office surgical excision of the type B postaxial polydactylous digit in infants and children in an office setting with the use of lidocaine with epinephrine demonstrates excellent results with improved safety without sacrificing quality.

Ulnar Polydactyly

A retrospective review identified 231 hands with PAPD-B in 132 newborns treated with surgical clips between January 1, 1996, and November 30, 2010, having a minimum of 2 years of follow-up.

Parent Perspectives for Type B Ulnar Polydactyly Management.

Although the majority of parents remain extremely satisfied with their child's outcome regardless of management type, time to treatment plays a determinative role in parents opting for ligation rather than excision in the operating room.

Long-Term Outcomes After Treatment for Type B Ulnar Polydactyly

While ligation and surgical excision result in similar function and esthetics, patient satisfaction is higher after surgery, advising parents of patients with type B ulnar polydactyly should include these considerations to assist them in selecting the best treatment for their child.

Local Anesthesia Alone for Postaxial Polydactyly Surgery in Infants

Results suggest the approach is quick, economical, and avoids the risks of GA in early infancy, and significantly decreased cost, LOS, and time to discharge using LA alone for surgical excision of postaxial polydactyly type B.

Decision-making and Management of Ulnar Polydactyly of the Newborn: Outcomes and Satisfaction.

A majority of parents whose children are born with type B post-axial polydactyly prefer to have the deformity addressed immediately with excision under local anesthesia at the bedside, and this can be accomplished safely, with a satisfaction score of 9.8 out of 10 and no appreciable residual deformity.

Management of Postaxial Polydactyly in the Neonatal Unit

A newborn with bilateral postaxial type B polydactyly underwent suture ligation to remove the supernumerary digit, but multiple ligation attempts were required.



Polydactyly in American negroes and whites.

It is pointed out that even though the total incidence of congenital malformations may be relatively similar in all large world populations, there are differences among populations in the incidence of specific mal Formations.

Congenital Abnormalities in the African Newborn

As no figures were available on the incidence and type of congenital abnormalities in African peoples, 2,068 consecutive newborn babies were examined by us and the results are given in this paper.

The prevalence rates of some of the common birth defects have been ascertained in a Black population in South Africa and compared with those found in other population groups in South African and, in some cases, in other African countries and in Negro groups in the USA and Canada.

A and B Postaxial polydactyly in two members of the same family

Two cases of previously unreported simultaneous presence of A and B postaxial polydactyly in two brothers out of 12 affected members of a kindred are reported, consistent with the hypothesis that in this family A and A types of postaxials are caused by a single gene rather than by two different genes.
