“…How about a patient's ability to weight bear immediately after sustaining an ankle fracture? Chien et al 6 recently investigated whether a patient's self-reported ability to weight bear at time of ankle fracture was predictive of radiographic stability. Examining a cohort of 121 patients, the authors demonstrated that a patient who was able to bear weight immediately after injury was more than 8 times more likely to have a stable ankle fracture.…”

“…Ranges from 3 to 7 mm have been reported with 3 to 5 mm being the most common. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15] Moreover, the exact location of where the MCS is measured varies. 5,13,15 To further characterize the radiographic assessment of ankle alignment, we propose an additional radiographic parameter to evaluate talar position, specifically the lateral tibial line (LTL) and the relationship of this line to the superolateral talus.…”

“…Even small shifts in talar position after fibula fracture create large increases in contact pressures that may lead to cartilage degeneration. 1,2 Such subtle changes in alignment are likely due to the integrity of the deltoid ligament. Several criteria have been used to assess deltoid ligament competence.…”

Background: Although the medial clear space (MCS) is commonly used to assess talar alignment and ankle stability, its measurement is variable with multiple reported normal values. We have observed that the lateral tibial shaft is a reliable landmark to assess talar alignment. The objective of the current investigation was to determine the normal relationship of the lateral tibia to the superolateral talus using a tangent drawn inferiorly from the lateral tibial shaft, which we refer to as the “lateral tibial line” (LTL). Methods: The relationship of the LTL to the superolateral talus was assessed by three reviewers on 99 standing ankle mortise radiographs in uninjured patients. This relationship was quantified by measuring the distance (in millimeters) between the LTL and the superolateral talus. In addition, the interobserver reliability of the LTL measurement was recorded and compared with that of the MCS. Results: The median value for the distance between the superolateral talus and LTL was −0.50 mm with an interquartile range of −1.4 to 0.0 mm. The LTL was within 1 mm of the lateral talus in 176 of 297 reviewer measurements (59.3%). Moreover, it was either lateral to or at most 1 mm medial to the lateral talus in 90.9% of cases. The LTL measurement also demonstrated good interobserver reliability (0.764, 95% confidence interval, 0.670 to 0.834), similar to the measurement of MCS (0.742, 95% confidence interval, 0.539 to 0.846). Conclusions: The relationship between the LTL and superolateral talus is easily measured with good reliability for assessing the anatomic relationship of the tibia and talus. The LTL uncommonly fell more than 1 mm medial to the superolateral talus, as might be seen with displaced ankle fractures. These findings will hopefully serve as a basis for future studies evaluating its role in assessing lateral displacement and stability of isolated fibula fractures. Level of evidence: Level III, retrospective review.
