Abstract

Post-traumatic posterior sternoclavicular dislocation is a rare injury that typically occurs in young men following high-energy trauma. It can cause potentially life-threatening complications due to compression of mediastinal structures and therefore requires treatment that achieves a stable reduction. Computed tomography (CT) plays a crucial diagnostic role, determining the type and degree of displacement and the anatomical relationship with mediastinal and cervical structures. We present the case of a 25-yearold man with post-traumatic posterior sternoclavicular dislocation who underwent ligament reconstruction using a modification of the classic figure-of-8 technique with a palmaris longus autograft.
