First of all, a reduction of the glenohumeral dislocation should be performed. In cases of undisrupted periosteal sleeves, this might be done in a closed manner (as illustrated). If the periosteal sleeve is disrupted, an open reduction of the glenohumeral dislocation becomes more likely. In these cases, it might become necessary to perform an arthrotomy to the glenohumeral joint via either an osteotomy of the lesser tuberosity or tenotomy of the subscapularis tendon.
Use a deltopectoral approach.
With longitudinal traction applied to the arm, the dislocated humeral head may be reduced using direct digital pressure pushing it back into position.
Option: bone hook
A bone hook can be placed carefully around the calcar avoiding damage to the articular cartilage. The head can then be pulled laterally and guided into position. Note: avoid neurovascular injury.
