“…McDermott et al 12 also could not find anatomical differences of the ATFL in healthy subjects or those with CAI on MRIs or on anatomical dissection. However, our values are in accordance with measurements of the lateral and medial malleolar lengths in healthy subjects as shown by Fessy and Mariani: the lateral malleolus was 24–29 mm, the medial malleolus was 13–13.4 mm 7 13. The distance from the tip of the fibula to the talar centre of rotation was significantly smaller by 3 mm in patients with CAI (table 2).…”

“…Although the ankle joint also exhibits a slight inversion/eversion of 5° in normal gait, the frontal curvature of the talus was not measured yet 7 9 10. The current results show that a deeper froCu can facilitate inversion injury.…”

“…The aim of this study was to describe characteristics of the osseous ankle configuration in the frontal plane as well as to determine further characteristics in the sagittal plane according to biomechanical considerations 6 7. The hypotheses of this study were that (a) a deeper curvature of the talus in the frontal plane facilitates inversion injuries; (b) the lateral malleolus would be longer in CAI, causing a less parallel position of the ATFL to an antero-inferior-orientated luxation force; (c) the talar centre of rotation is not exactly in the tibial axis as has been assumed4 6; and (d) the lateral tibial surface angle would be smaller in CAI.…”

“…It is therefore possible to postulate significant differences in distal tibial dimensions. Such differences in the dimensions of the distal tibia have been reported for the fibular incisura, the medial malleolus and the tibial plafond [4]. Due to populational differences exhibited by osteometric dimensions, formula derived for a particular population is not applicable to other populations [5].…”

Background: In forensic analysis, the estimation of the stature is key in identification of an individual. The stature of an individual can be estimated from long bones especially the tibia and the femur as these have direct correlation to the height of an individual. The tibia is ideal in this application as it resists erosion and keeps its anatomical shape for long even after burial. Mechanical loading is especially high in the distal ends of long bones of the lower limb and as such they display significant inter-individual differences. The use of distal dimensions in estimation of the length of the tibia from skeletal remains has not been reported.Materials and methods: 150 dry and processed tibias irrespective of side, grossly normal and complete were randomly collected from a medical college of south India. Unossified bones, bones with diseases and injuries have been excluded.Results: In our study, the mean and standard deviation was calculated for each of the dimensions. The results were analysed with simple regression analysis. Pearson's coefficient determined for each parameter and tabulated. Simple linear regression equations were then deduced from the obtained data which would predict the expected maximum length of the bone from its various other parameters.Conclusion: Simple regression equations are deducted from the obtained data, which would predict the expected maximum length of the tibia from its various parameters.

“…Computerized Tomography (CT) scans can be used to obtain more accurate morphological data of the ankle bones [20] than those obtained from 2D images [4,21]. However, since CT scans are expensive and involve relatively high radiation dosage, 2D imaging is still in use clinically for evaluating the ankle and selecting the size of the prosthesis.…”

BackgroundMeasurements of the morphology of the ankle joint, performed mostly for surgical planning of total ankle arthroplasty and for collecting data for total ankle prosthesis design, are often made on planar radiographs, and therefore can be very sensitive to the positioning of the joint during imaging. The current study aimed to compare ankle morphological measurements using CT-generated 2D images with gold standard values obtained from 3D CT data; to determine the sensitivity of the 2D measurements to mal-positioning of the ankle during imaging; and to quantify the repeatability of the 2D measurements under simulated positioning conditions involving random errors.MethodFifty-eight cadaveric ankles fixed in the neutral joint position (standard pose) were CT scanned, and the data were used to simulate lateral and frontal radiographs under various positioning conditions using digitally reconstructed radiographs (DRR).Results and discussionIn the standard pose for imaging, most ankle morphometric parameters measured using 2D images were highly correlated (R > 0.8) to the gold standard values defined by the 3D CT data. For measurements made on the lateral views, the only parameters sensitive to rotational pose errors were longitudinal distances between the most anterior and the most posterior points of the tibial mortise and the tibial profile, which have important implications for determining the optimal cutting level of the bone during arthroplasty. Measurements of the trochlea tali width on the frontal views underestimated the standard values by up to 31.2%, with only a moderate reliability, suggesting that pre-surgical evaluations based on the trochlea tali width should be made with caution in order to avoid inappropriate selection of prosthesis sizes.ConclusionsWhile highly correlated with 3D morphological measurements, some 2D measurements were affected by the bone poses in space during imaging, which may affect surgical decision-making in total ankle arthroplasty, including the amount of bone resection and the selection of the implant sizes. The linear regression equations for the relationship between 2D and 3D measurements will be helpful for correcting the errors in 2D morphometric measurements for clinical applications.
