Atypical cleft hand with complex syndactyly: An unusual form of hand oligodactyly

Abstract

Hand oligodactyly refers to a developmental defect which results in the presence of less than 5 digits on a hand. It presents as a component of 4 main categories of congenital upper limb malformations. Herein, we present a 50-year-old man with an unusual form of hand oligodactyly which is characterized by atypical cleft hand accompanied by complex syndactyly between the thumb and the index finger. Accurate characterization of hand oligodacticity can sometimes be challenging due to unusual phenotypic appearances accompanying the abnormality. Radiological evaluation is of great importance for correct identification and classification of such complex hand anomalies, and the treatment should be highly individualized in these patients.

The Surgical Closure of Neglected Ulnar Deficiency of the Hand; Unclassified Phenomenon “Ulnar Cleft Hand”

“…Since our case had an ulnar cleft hand, we applied a different intervention than the central cleft hand. Unlike the classical approach [23][24][25][26][27] due to the shifting of the ulnar row to ulnar side, we performed additional tenotomies and carpal fusion while centralizing the ulnar row.…”
