Thumb Duplication - Simple Surgery for a Common Problem?[1]

Zusammenfassung

Polydaktylien gehören zu den häufigsten angeborenen Handfehlbildungen, und der Doppeldaumen ist ihre häufigste Manifestation. Dennoch sind die Ergebnisse der operativen Korrektur von Doppeldaumen oftmals so enttäuschend, so dass weitere Korrekturoperationen erforderlich werden, um vermeidbare postoperative Deformitäten zu beheben. Beispiele von Doppeldaumen, ihre charakteristische und vorhersehbare abnorme Anatomie und die anspruchsvolle Operationstechnik für die Reduktionsplastik von Doppeldaumen werden demonstriert.

Abstract

Polydactyly is one of the most common congenital anomalies of the hand, and thumb duplication the most common manifestation of polydactyly. Despite this, the results of surgical treatment for thumb duplication are frequently disappointing, and deformities secondary to improperly executed reduction procedures often make further corrective surgery necessary. Examples of thumb duplication, their characteristic abnormal anatomy, and the complexity of surgical reduction procedures are illustrated.
