Syndactyly can be classified as simple when it involves soft tissues only and as complex when it involves the bone or nail of adjacent fingers. Syndactyly is a condition wherein two or more digits are fused together. 21 Heritable forms of syndactyly are transmitted in an autosomal-dominant pattern with variable In syndactyly, the extent and intensity of digital union is variable, which guides the classification scheme. Syndactyly Classification Finally, syndactyly is a very relevant model to study the interaction of genetic mechanisms, epigenetic events, pleiotropy and stochastic factors, which generate extreme clinical heterogeneity in affected subjects and families. Two types. The differentiation into complete syndactyly includes the fingertips and partial syndactyly with a web space that can reach anywhere between a normal web space and the fingertips can describe all forms of syndactyly.

Apr 27, 2022 · The classification system of Temtamy and McKusick for non-syndromic syndactyly is largely based on the phenotypic appearance (nature or site of affected limbs), along with segregation of the disorder in affected families . Summary of nonsyndromic and selected syndromic syndactyly with their known causal genes. The classification system of Temtamy and McKusick provided the basis for the latest modern classification system, which Syndactyly is a condition well documented in current literature due to it being the most common congenital hand defect, with a large aesthetic and functional significance. First, the majority of The classification system of Temtamy and McKusick for non-syndromic syndactyly is largely based on the phenotypic appearance (nature or site of affected limbs), along with segregation of the disorder in affected families . 19,20 Unilateral presentation is equally as common as bilateral presentation. This condition can occur in both the upper and lower extremities, creating the appearance of "webbed" or "super" digits, depending on the degree of fusion. Currently, there is a paucity of knowledge regarding the exact developmental mechanism leading to this condition. if soft 1 Classification. 28 Subtype 1 (Weidenreich type or zygodactyly) accounts for 70% of nonsyndromic Syndactyly.
