All patients had a union in 14 (12\u201318) weeks. The mean NSA is 135\u00b0 (112\u2013155\u00b0). One hundred and thirteen patients with an NSA of &gt;120\u00b0 had a good functional outcome. Fourteen patients with NSA \u2264120\u00b0 had shoulder abduction &lt;90\u00b0. The mean GT to AS distance is 7.2 mm (\u22122 to 16). The superior displacement of GT above AS is associated with abduction of &lt;90\u00b0 (16 patients). The mean medial gap is 3 mm (0\u201317). In 14 patients with a medial gap of &gt;4 mm and without calcar screw, varus collapse is observed. All patients had a good outcome on DASH score and 122 patients had good to excellent outcome on C-M score. Five patients with poor outcome on C-M score had NSA &lt;120\u00b0 and displacement of GT above AS.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Radiographic indicators for poor outcome are varus angulation with NSA &lt;120\u00b0, superior displacement of GT above AS, the presence of medial gap &gt;4 mm, and absence of calcar specific screw.
