“…The CT scan was performed analogous to the protocol described by Beimers et al 46 Sagittal 1.0-mm slices were reformatted in two planes, because the lateral and medial talar facets have different anatomic orientations; one set of reconstructions was made parallel to the lateral talar facet and one set parallel to the medial talar facet. These sagittal planes were identified on the original axial scans and reformatted in a standardized fashion.…”

“…Analogous to the protocol as described previously, 46 a Philips MX8000 spiral CT scanner (Philips Medical Systems, Eindhoven, the Netherlands) was used with the following settings: tube voltage, 120 kV; tube current, 26 mAs; collimation, 2 ´ 0.5 mm; slice thickness, 0.6 mm; slice increment, 0.3 mm; voxel size, 0.3 ´ 0.3 ´ 0.3 mm; image matrix, 512 ´ 512 pixels; rotation time, 0.75 s; resolution, ultra high; kernel, D (sharp); and gantry tilt, 0. Th e examined volume included the distal tibia and the complete talus.…”

“…Variations in loading during inversion and eversion of the foot are commonly encountered and result in compensatory alterations in gait patterns in healthy subjects [9,10]. In addition, flat ground-loading models do not examine the foot and ankle complex in the frontal (coronal) plane where the subtalar joint contributes to maintain lower limb alignment with a loaded plantar foot position [5]. Subsequently, provocative loading conditions (inverted and everted orientations of the foot) are warranted to capture alterations in ankle biomechanics after arthrodesis of the hindfoot.…”

Background While successful subtalar joint arthrodesis provides pain relief, resultant alterations in ankle biomechanics need to be considered, as this procedure may predispose the remaining hindfoot and tibiotalar joint to accelerated degenerative changes. However, the biomechanical consequences of isolated subtalar joint arthrodesis and additive fusions of the Chopart's joints on tibiotalar joint biomechanics remain poorly understood. Questions/purposes We asked: What is the effect of isolated subtalar fusion and sequential Chopart's joint fusions of the talonavicular and calcaneocuboid joints on tibiotalar joint (1) mechanics and (2) kinematics during loading for neutral, inverted, and everted orientations of the foot? Methods We evaluated the total force, contact area, and the magnitude and distribution of the contact stress on the articular surface of the talar dome, while simultaneously tracking the position of the talus relative to the tibia during loading in seven fresh-frozen cadaver feet. Each foot was loaded in the unfused, intact control condition followed by three randomized simulated hindfoot arthrodesis modalities: subtalar, double (subtalar and talonavicular), and triple (subtalar, talonavicular, and calcaneocuboid) arthrodesis. The intact and arthrodesis conditions were tested in three alignments using a metallic wedge insert: neutral (flat), 10°i nverted, and 10°everted. Results Tibiotalar mechanics (total force and contact area) and kinematics (external rotation) differed owing to hindfoot arthrodeses.

Hindfoot arthrodesis also was associated with increased external rotation of the tibiotalar joint during loading: subtalar arthrodesis in the neutral loading position (3.3°± 1.6°; 95% CI, 2°-4.6°; p = 0.004) and everted loading position (4.8°± 2.6°; 95% CI, 2.7°-6.8°; p = 0.043); double arthrodesis in neutral (4.4°± 2°; 95% CI, 2.8°-6°; p = 0.003) and inverted positions (5.8°± 2.6°; 95% CI, 3.7°-7.9°; p = 0.002), and triple arthrodesis in all loaded orientations including neutral (4.5°±1.8°; 95% CI, 3.1°-5.9°; p = 0.002), inverted (6.4°± 3.5°; 95% CI, 3.6°-9.2°; p = 0.009), and everted (3.6°± 2°; 95% CI, 2°-5.2°; p = 0.053) positions.

“…Although previous studies [13][14][15][16][17] have measured hindfoot motion on live and cadaveric foot specimens three-dimensionally by using an externally applied goniometer, and based upon these data, have modeled hindfoot motion by using combinations of simple hinges, the lack of external land marks of the talus in combination with the subtalar joint geometry has made the subtalar joint kinematics difficult to investigate in living subjects [18]. Also, these models were less than satisfactory because they failed to adequately describe the complex multi-axial motion of the hindfoot [19].…”
