The surgical technique is analogous to radial polydactyly, in which the level of duplication and anatomical components should guide operative treatment. The pedicled ulnar extra digit can be removed by  suture ligation to devise the skin bridge of the newborn child. This might be easier than an excision of the extra digit when the child is 6 to 12 months old. Ligation occludes the vascular supply to the duplicated digit, resulting in dry gangrene and subsequent autoamputation. This must be done with consideration of the presence of a neurovascular bundle, even in very small skin bridges. When the ligation is done inappropriately it can give a residual nubbin. Also, a neuroma can develop in the area of the scar. An excision can prevent the development of a residual nubbin and the sensitivity due to a neuroma. For infants with ulnar type B polydactyly the recommended treatment is ligation in the neonatal nursery. Studies have shown that excision of the extra digit in the neonatal nursery is a safe and simple procedure with a good clinical and cosmetic outcome. Radial polydactyly
Because neither of the two thumb components is normal, a decision should be taken on combining which elements to create the best possible composite digit. Instead of amputating the most hypoplastic thumb, preservation of skin, nail, collateral ligaments and tendons is needed to augment the residual thumb. Surgery is recommended in the first year of life, generally between 9 and 15 months of age. Surgical options depend on type of polydactyly.
A nematode infection is a type of helminthiasis caused by organisms in the nematode phylum.An example is enterobiasis. Several antinematodal agents are available. References
