title: [A new reduction technique for posterior locked shoulder dislocation. Case report and technique description].
abstract: The case of a 61-year-old male with posterior dislocation of the right shoulder joint is presented and a new technique for closed reduction of posterior locked shoulder dislocation is described. The technique involves four steps: in step 1 a constant traction is applied on the injured arm, in step 2 the arm is internally rotated and in steps 3 and 4  the second arm of the physician is used as a lever arm to lateralize and ventralize the shoulder. Lateralization and ventralization of the humeral head are essential to engage the humeral head and to pass it around the glenoid during reduction. Steps 3 and 4 are performed simultaneously. In the presented case the patient suffered a traumatic shoulder dislocation with a rim fracture of the glenoid. After reduction the shoulder was stable and conservative treatment was performed. A 2 year follow-up examination revealed a pain-free and stable shoulder with free range of motion and an Oxford instability score of 48 points. The described reduction technique for posterior locked shoulder dislocation is a simple and gentle technique, which can be performed easily by one person.Presentation of a reduction technique for locked posterior shoulder dislocation. Constant traction and internal rotation is performed for engaging the locked humeral head. After disengaging the humeral head the reduction is performed by using the arm of the physician as a lever arm.
