The LDTA was the angle between the long axis of the tibia and a line drawn across the most radiodense part of the tibial plafond. The paired t-test was used to compare the LDTA of the 2 measurements.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results.<\/jats:title>\n                    <jats:p>The mean LDTA on the 0\u00b0 orthogonal radiographs was 89\u00b0 (range, 87\u00b0-92\u00b0), whereas the mean LDTA on the 15\u00b0 craniocaudal radiographs was 79\u00b0 (range, 77\u00b0\u201381\u00b0). The mean difference was 10\u00b0 (range, 9\u00b0-12\u00b0; p&lt;0.0001). In the 15\u00b0 craniocaudal radiographs, the ankle joint appeared to have valgus malalignment.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion.<\/jats:title>\n                    <jats:p>During intramedullary nailing of the tibia, the knee is usually flexed and the image intensifier may not swing over far enough.
