The Migration of a Broken Pin Following Fixation of the Acromioclavicular Joint: A Case Report and Review of the Literature

Abstract

The use of smooth and threaded pins for internal fixation is often complicated by component migration, especially when employed about the acromioclavicular joint. A case report of pin breakage with subsequent migration is presented. This phenomenon occurred despite efforts to stabilize the pin corroborating the potential hazards and unpredictability of these implants. A protocol for the management of these devices, before and after component failure, is presented.
