CMN lag screw was placed in \u201cdynamic\u201d mode to allow for controlled collapse, or screw \u201cslide.\u201d Screw slide was defined as the difference in lateral prominence of the lag screw at latest follow up compared to its initial position. Patients were grouped based on the amount of screw slide (&lt;5\u2009mm, 5\u201315\u2009mm, &gt;15\u2009mm) and correlation analysis was performed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      614 intertrochanteric hip fracture patients were identified (mean age 80.76\u2009years; 72.3% female) with mean 6.2\u2009months follow-up. Mean amount of slide was 3.77\u2009\u00b1\u20094.79\u2009mm. 66.3% of patients had &lt;5\u2009mm of slide, while 31.3% had 5\u201315\u2009mm and 2.4% had &gt;15\u2009mm.
