  Asymmetric bilateral hip dislocations with an associated unstable pelvic ring injury: A Case Report

  Jacob Shermetaro, Jourdan Gard, and Kelley Brossy

  Publication Date: 5-2022

  Introduction • Asymmetric bilateral hip dislocations are rare injuries with one hip dislocating posteriorly while the contralateral hip dislocates anteriorly • .01%-0.02% of all joint dislocations1 • Even fewer of these injuries have been reported with an associated unstable pelvic ring injury • We report a case of asymmetric bilateral hip dislocations with an associated unstable pelvic ring injury and femoral head fracture

  An Irreducible Posterior Shoulder Fracture-Dislocation: A Case Report

  Josiah Valk, Jacob Shermetaro, David Sosnoski, and Kelley Brossy

  Publication Date: 5-2022

  Introduction • The shoulder is the most frequently dislocated joint in the body, but most commonly dislocated anteriorly • Posterior fracture-dislocations of the shoulder are exceedingly rare orthopedic injuries that only account for 2-5% of traumatic shoulder dislocations • These injuries have a reported annual prevalence of 0.6/100,0001 • Most commonly they are a result of high energy trauma, electrocution, or seizures caused by forced flexion, adduction and internal rotation of the shoulder • Timely diagnosis is critical for appropriate early treatment in order to help prevent complications such as avascular necrosis • Thorough physical and radiographic examination are needed to confirm diagnosis which may be missed or delayed in up to 79% of cases.
