The incidence of conjoined twins is not accurately known because most of them end in abortions or stillbirths and hence may not be recorded. The heteropagus types are rare, in which one member, the autosite, is normal or nearly so. This bears an incomplete member, the parasite, which is completely dependent upon it. This article describes a pair of heteropagus twins separated at the Ahmadu Bello University Teaching Hospital in Zaria, Nigeria. In this case, the history of twins in the families of both parents seems to be a contributory factor to the twinning process, though the mechanism of this predisposition is not explained. |
