Reverse Essex-Lopresti and Other Forms of Longitudinal Forearm Instability.

Abstract

Summary: Longitudinal forearm instability is a consequence of interosseous ligament complex disruption. Radiographic identifiers should alert the surgeon to the disrupted structures. Understanding the injury pattern can simplify the treatment process. The clinical presentation will vary based on the involved interosseous ligament components. The surgeon should aim to restore the anatomic radioulnar relationship and then address the remaining pathology as needed. The central band is the foundational structure that maintains this relationship and should be addressed in each injury pattern when disrupted. In this study, we describe rare forms of longitudinal forearm instability.
