Open figure-of-8 configuration for traumatic posterior sternoclavicular joint dislocation of the shoulder: A novel technique

Abstract

Posterior dislocation of the sternoclavicular joint (SCJ) is a rare clinical condition requiring surgical management. Various surgical techniques have been described in the literature, but those involving bone tunnels carry an increased risk of residual instability and iatrogenic fractures. We present a novel surgical technique for the management of both acute and chronic posterior SCJ dislocations, based on a figure-of-eight configuration with autograft, which ensures joint stability while preserving its natural mobility. Furthermore, the use of a single clavicular tunnel oriented orthogonally to two sternal tunnels creates a highly stable three-dimensional construct and reduce iatrogenic fractures.
