Functional evaluation was assessed through the Functional Independence Measure (FIM\u2122) instrument and Parker\u2019s New Mobility Score (NMS). Radiological follow-up included the degree of the reduction according to the Baumgartner criteria, the Tip-Apex Distance, and the shortening of the telescoping screws and its lateral protrusion.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Pre-operative mean FIM\u2122 and NMS were 4.3 (range 1\u20139) and 98.7 (range 22\u2013126), respectively. At the 12-month follow-up the average FIM\u2122 and NMS were 95.3 (range 22\u2013126) and 3.7 (range 1\u20139), respectively. Mean shortening of the lag screws was 4.3\u00a0mm (range 1\u20138) and mean lateral protrusion was 1.7\u00a0mm (range 0\u20133). 3 Cases (0.70%) of non-consolidation requiring reoperation were recorded. 1 Case (0.24%) of these cases was also characterized by nail breakage.
