The test conditions included: intact, 30% glenoid defect, and reconstruction of the defect with the classic and congruent Latarjets. The Latarjet techniques were randomly ordered, with the outcome variables being anterior dislocation, glenohumeral translation, rotational range of motion, and joint stiffness.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      All 8 specimens dislocated after creation of a 30% glenoid defect. The classic Latarjet stabilized 7 of 8 specimens, whereas the congruent\u2010arc modification stabilized all specimens (8\/8). In abduction neutral rotation, there was no difference in joint translation between techniques (\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .613). In abduction external rotation, there was significantly greater anterior humeral head translation after the congruent technique than after the classic (9.9 and 6.5 mm, respectively,\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .013). Rotational range of motion was significantly reduced after classic (\u221225.8\u00b0) and congruent (\u221222.2\u00b0) transfers as compared with the 30% defect (\n                      <jats:italic>P<\/jats:italic>\n                      \u2264 .041). Joint stiffness in the abducted, externally rotated position was significantly reduced in the 30% defect as compared with intact (\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .012), congruent (\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .015), and classic (\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .001) conditions.

The techniques do not substantially differ in rotational range of motion or joint stiffness. The congruent\u2010arc technique, however, does result in significantly greater anterior humeral head translation, as compared with the classic technique, before reaching a stable non\u2010dislocated endpoint.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Clinical Relevance<\/jats:title>\n                    <jats:p>On the basis of this biomechanical model, both the classic and congruent\u2010arc Latarjet techniques can be used to stabilize a shoulder with substantial glenoid bone loss.
