- Technique for Surgical Neck Frx:
    - use 2.5 mm terminally threaded AO Schanz pins;
    - following appropriate reduction, one pin is inserted thru lateral arm, at a point 8 cm distal to acromion in order to avoid
           axillary nerve;
    - second pin is inserted parallel to the first;
    - third pin is inserted to form a triangular configuration;
    - finally a fourth pin is inserted from greater tuberosity to medial humeral shaft;
