Clinical evaluation included the Simple Shoulder Test, Constant score, pain score of 0 to 10, and satisfaction graded 0 (not satisfied) to 4 (very satisfied). Fourteen patients had complete outcome scores at the final follow-up. Nine patients underwent radiographic examination and were assessed for coracoclavicular distance, posterior acromioclavicular subluxation, arthritis, ossification, and hardware displacement by 3 observers.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      The respective mean preoperative, 2-year, 5-year, and 15-year outcome scores were as follows: 34.5 \u00b1 6.9, 94.3 \u00b1 3.2 (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; .05), 91.5 \u00b1 4.7, and 91.2 \u00b1 4.8 (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &gt; .05) for the Constant score; 2.8 \u00b1 2.1, 12.0 \u00b1 0 (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; .05), 11.8 \u00b1 0.5, and 11.7 \u00b1 0.4 (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &gt; .05) for Simple Shoulder Test; and 4.5 \u00b1 1.9, 0.3 \u00b1 0.5 (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; .05), 0.3 \u00b1 0.6, and 0.4 \u00b1 0.8 (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &gt; .05) for pain.
