“…Statistics were not used to compare contributions of the subtalar and tibiotalar to the overall arc of motion at the ankle, but results from the feasibility study are comparable to the literature (S -Table 5) [12,15]. For the volunteer, the mean change in subtalar inversion/eversion during toe-off in our subject was approximately five times that of the tibiotalar joint (15.51±3.80° versus 3.82±1.28°), strengthening the belief that the subtalar joint is primarily responsible for this motion as previously postulated (e.g., Yamaguchi et al) [7,12]. Still, the tibiotalar joint M a n u s c r i p t 14 offered inversion/eversion, a phenomenon that will be explored in future studies.…”

“…Intra-cortical pins with reflective markers have independently tracked the tibia, talus, and calcaneus [4,5], but this approach is highly invasive. Other studies have used single plane fluoroscopy to study invivo motions of the ankle [6][7][8]. However, out-of-plane motions, such as axial rotation of the subtalar joint, cannot be accurately measured with single plane fluoroscopy [9].…”

Accuracy and feasibility of high-speed dual fluoroscopy and model-based tracking to measure in vivo ankle arthrokinematics

The relationship between altered tibiotalar and subtalar kinematics and development of ankle osteoarthritis is unknown, as skin marker motion analysis cannot measure articulations of each joint independently. Here, we quantified the accuracy and demonstrated the feasibility of high-speed dual fluoroscopy (DF) to measure and visualize the three-dimensional articulation (i.e., arthrokinematics) of the tibiotalar and subtalar joints. Metal beads were implanted in the tibia, talus and calcaneus of two cadavers. Three-dimensional surface models of the cadaver and volunteer bones were reconstructed from computed tomography images. A custom DF system was positioned adjacent to an instrumented treadmill. DF images of the cadavers were acquired during maximal rotation about three axes (dorsal-plantar flexion, inversion-eversion, internal-external rotation) and simulated gait (treadmill at 0.5 and 1.0 m/s). Positions of implanted beads were tracked using dynamic radiostereometric analysis (DRSA). Bead locations were also calculated using model-based markerless tracking (MBT) and compared, along with joint angles and translations, to DRSA results. The mean positional difference between DRSA and MBT for all frames defined bias; standard deviation of the difference defined precision. The volunteer was imaged with DF during treadmill gait. From these movements, joint kinematics and tibiotalar and subtalar bone-to-bone distance were calculated. The mean positional and rotational bias (±standard deviation) of MBT was 0.03±0.35 mm and 0.25±0.81°, respectively. Mean translational and rotational precision was 0.30±0.12 mm and 0.63±0.28°, respectively. With excellent measurement accuracy, DF and MBT may elucidate the kinematic pathways responsible for osteoarthritis of the tibiotalar and subtalar joints in living subjects.

“…A further explanation for this discrepancy may be due to the asymptomatic population used within the study. Symptomless individuals must possess at least 10 0 of ankle DF-ROM in order to walk, descend stairs or kneel (Crosbie et al, 1999), whilst at least 20 0 is needed for running (Yamaguchi et al, 2009). Indeed, the baseline characteristics of the participants were analogous to normative ranges in healthy adults (Hoch & McKeon, 2011b).…”

“…(While the examples discussed in this paper are foot specific, the principles apply to any joint in the body.) Methods include X-ray stereophotogrammetry [1,2], time sequence magnetic resonance imaging (MRI) [3], retro-reflective markers, placed either on the skin [4] or on bone pins [5], or recently, single [6] and biplane fluoroscopy [7,8]. Some of these methods involve ionizing radiation (X-ray stereophotogrammetry and fluoroscopy) or are highly invasive (X-ray stereophotogrammetry and bone pins), leaving time sequence MRI, and skin mounted markers as the safest methods.…”

We report an image segmentation and registration method for studying joint morphology and kinematics from in vivo magnetic resonance imaging (MRI) scans and its application to the analysis of foot and ankle joint motion. Using an MRI-compatible positioning device, a foot was scanned in a single neutral and seven other positions ranging from maximum plantar flexion, inversion, and internal rotation to maximum dorsiflexion, eversion, and external rotation. A segmentation method combining graph cuts and level set was developed. In the subsequent registration step, a separate rigid body transformation for each bone was obtained by registering the neutral position dataset to each of the other ones, which produced an accurate description of the motion between them. The segmentation algorithm allowed a user to interactively delineate 14 foot bones in the neutral position volume in less than 30 min total (user and computer processing unit [CPU]) time. Registration to the seven other positions took approximately 10 additional minutes of user time and 5.25 h of CPU time. For validation, our results were compared with those obtained from 3DViewnix, a semiautomatic segmentation program. We achieved excellent agreement, with volume overlap ratios greater than 88% for all bones excluding the intermediate cuneiform and the lesser metatarsals. For the registration of the neutral scan to the seven other positions, the average overlap ratio is 94.25%, while the minimum overlap ratio is 89.49% for the tibia between the neutral position and position 1, which might be due to different fields of view (FOV). To process a single foot in eight positions, our tool requires only minimal user interaction time (less than 30 min total), a level of improvement that has the potential to make joint motion analysis from MRI practical in research and clinical applications.
