“…Type classification by the number of TAT fiber bundles has long been reported in many cadaveric studies [8,[11][12][13][14][15][16]. For Type I, Olewnik et al [12] examined the attachment site area of the TAT using 100 fixed Caucasian cadavers and reported that 32 cadavers (32%) showed a single bundle of fibers.…”

“…The anatomy of the TAT has long been reported in previous studies using cadavers. Regarding the attachment of the TAT to bone, types with one, two, and three fiber bundles have been reported [8,[11][12][13][14][15][16], with the two-bundle type reported as the most frequent [8,11,12,14,15]. Regarding the type with a single bundle of fibers, Musial et al [14] and Willegger et al [8] found no types with a single fiber bundle in their studies of 122 and 41 fixed cadavers, respectively.…”

“…In addition, Olewnik et al [12] suggested that TAT attachment types may vary by ethnicity. Further, very few studies have examined the footprint (attachment site area) of the TAT, and most studies are limited to examinations of the width and thickness of the TAT and the shape of the footprint [8,[11][12][13][14][15][16]. A previous study [8] examining the footprint of the TAT reported that the mean attachment site area to MCB was 71.5 mm2 (range, 20.1-151.0 mm2) and that to 1MB was 48.1 mm2 (range, 18.5-97.0 mm2) for the type with two bundles of the TAT.…”

The purpose of this study was to clarify the attachment types of the tibialis anterior tendon (TAT) in Japanese fixed cadavers and to determine the attachment site area in three dimensions. We examined 100 feet from 50 Japanese cadavers. The TAT was classified according to differences in the number of fiber bundles as: Type I, with one fiber bundle; Type II, with two fiber bundles; and Type III, with three fiber bundles. The attachment site area of the TAT was measured using a three-dimensional scanner. Cases were Type II in 95% and Type III in 5%, with no cases of Type I identified. In Type II, mean attachment site areas were 85.2 ± 18.2 mm2 for the medial cuneiform bone (MCB) and 72.4 ± 19.0 mm2 for the first metatarsal bone (1MB), showing a significantly larger area for MCB than for 1MB. These findings suggest the possibility of ethnic differences in TAT attachment types and suggest that TAT attachments in Japanese individuals are highly likely to be Type II, with rare cases of Type III. Accurate measurement of attachment site areas is possible with appropriate three-dimensional measurements.

Sensitivity of musculoskeletal models to variation in muscle architecture parameters

et al. 2022

Musculoskeletal models, like all theoretical models of physical processes, depend on the assumptions needed to construct the model. For musculoskeletal models, these assumptions include, among other things, the kinematic data, the kinetic data, and the muscle parameters. The former (dynamic) data can be acquired relatively easily from living subjects, but the latter are usually based on limited information, frequently determined from cadaver studies performed on elderly individuals. Previously, we determined the sensitivity of forces to dynamic differences among ten humans walking in a straight path. Here, we assess the sensitivity of the muscle and joint reaction forces developed in human walking to variable muscle parameters obtained from ten living adults, whose data were recently reported, and compared the results to the values from a standard model that depends on cadaveric data. We found that, while the force patterns across the stance cycle were similar among muscle parameter models, differences of as much as 15% in the force magnitude were produced. Whether or not the variation between the standard model and other muscle parameters is important depends on why the forces are required.
