An Alternative Surgical Approach to Pseudoainhum: A Case Report.

Abstract

Pseudoainhum is a disorder of unknown etiology that is usually congenital and nonprogressive. One theory states it is caused by amnion band constriction in utero. These constriction bands lead, not only to a less cosmetically appealing foot, but also to long-term neurovascular compromise, resulting in amputation of the digit. The described surgical approaches have been limited within published data. The 2 procedures that have been described are either a Z-plasty or amputation, depending on the degree of the deformity. The present case report provides an alternative surgical approach to a pseudoainhum deformity of a third digit.
