Digital constriction bands in pseudoainhum: morphological radiographic, and histological analysis.

Abstract

Pseudoainhum is a rare condition of unknown etiology that produces digital constricting rings, most commonly on the small fingers. A thorough discussion of pseudoainhum in the plastic surgical literature is apparently lacking at this time. The authors describe the gross morphology, radiographic and laboratory features, and surgical pathology of the disease, and provide well-defined guidelines for its treatment.
