Posterior Shoulder Dislocation due to an Unusual Injury Mechanism

We present a case of a 21-year-old male who sustained a posterior dislocation of his dominant shoulder following poor weightlifting technique. His shoulder was highly unstable following the injury. The shoulder dislocation was initially reduced by an Orthopaedic surgeon using closed technique in the emergency department. The shoulder was immobilised in an abduction, external rotation brace, and Orthopaedic Trauma clinic follow up was arranged. Ongoing symptomatic instability warranted operative stabilisation. We present this case with its previously undocumented mechanism, to highlight the injury to frontline emergency medical teams, create awareness of its presentation and to discuss its potential mechanism and treatment.
