The titanium version of the MILN (PRECICE<jats:sup>\u00ae<\/jats:sup>) has been in use since 2011 but had limitations (50\u201375 lb) in post-operative weight bearing. A new stainless-steel version of the MILN (STRYDE<jats:sup>\u00ae<\/jats:sup>) allows 150\u2013250 lb of post-operative weight bearing.<\/jats:p>\n                <jats:p>The aim is to compare the outcomes of using these two different MILNs for both unilateral and bilateral femoral lengthening.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>A single-center, retrospective cohort study was conducted in which patients\u2019 records were reviewed from the period from January 2017 to March 2020. A total of 66 femoral lengthening procedures were included in the study and were divided into two groups: STRYDE<jats:sup>\u00ae<\/jats:sup> group (30 femora) and PRECICE<jats:sup>\u00ae<\/jats:sup> group (36 femora). Outcomes assessed were the 6-months post-operative Limb Deformity-Scoliosis Research Society (LD-SRS) Score, adjacent joint range of motion (ROM), average distraction rate, bone healing index (BHI), and complications.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>No statistically significant difference was found between the two groups in regard to the (LD-SRS) score, hip ROM, or knee ROM. Statistically significant differences were found between the two groups in regard to BHI (average of 0.84 months\/cm and 0.67 months\/cm for STRYDE<jats:sup>\u00ae<\/jats:sup> and PRECICE<jats:sup>\u00ae<\/jats:sup>, respectively) and distraction rate (average of 0.6 mm\/day and 0.9 mm\/day for STRYDE<jats:sup>\u00ae<\/jats:sup> and PRECICE<jats:sup>\u00ae<\/jats:sup>, respectively).<\/jats:p>\n                <jats:p>No mechanical nail complications were reported in the STRYDE<jats:sup>\u00ae<\/jats:sup> group compared to three events of nail failure in the PRECICE<jats:sup>\u00ae<\/jats:sup> group. One femur in the PRECICE<jats:sup>\u00ae<\/jats:sup> group needed BMAC injection for delayed healing compared to four femurs in the STRYDE<jats:sup>\u00ae<\/jats:sup> group.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>The STRYDE<jats:sup>\u00ae<\/jats:sup> MILN yields comparable functional results to those of PRECICE<jats:sup>\u00ae<\/jats:sup> MILN and shows fewer mechanical nail complications.
