Which is true about shoulder dislocation?: (A) Anterior dislocation is common than posterior, (B) Fixed medial rotation in posterior dislocation, (C) Kocher's manoeuvre is effective in anterior dislocation, (D) All of the above
Answer is D. D i.e. All of the above - Anterior dislocation of humerus produces an impaction fracture (defect) in the posterolateral aspect of humeral head (k/ a Hill-Sachs lesion) whereas, recurrent posterior dislocation of humerus produces an impaction fracture (defect) in the anteromedial humeral head (k/a reverse Hill Sachs lesion or Trough sign).- Most of the traumatic dislocations heal and would never recurrQ.
