These bone degenerations were found to be correlated with those on the other side of the ankle t, the medial margin of the talar trochlea and the lateral articular surface of the talus, respectively. In contrast, the amount of bone depression on the plafond was smaller than ly anticipated. Such quantitative information about stereotypical patterns of bone degeneration in ankle OA would contribute to better understanding of the development of ankle OA and possible therapeutic interventions.

Ankle osteoarthritis OA is a common progressive disease characterized by destruction of articular cartilage and bony degeneration around the tibiotalar t 1. In addition, coronal-plane varus malalignment at the level of the tibiotalar t is often observed in ankle OA 2. studies have examined the morphological characteristics of the distal tibia in varus ankle OA using plain radiographs and reported that varus tilt of the tibia, Free Connecticut sex classified opening of the plafond, and distal opening of the articular surface of the medial malleolus 345 were the main morphological manifestations in ankle OA.

However, two-dimensional assessment based on a plain radiograph is not sufficient to capture the complex morphology of osteophyte formation and bone resorption in ankle OA, which is essentially three-dimensional. A few published studies have assessed the three-dimensional morphology of the ankle mortise in ankle OA using computed tomography CT. Wiewiorski et al.

Similarly, Schaefer et al. However, to the best of authors' knowledge, those are the only studies published so far. Detailed assessment and quantification of the pattern of the morphological degeneration of the ankle t formed by the tibia, fibula, and talus have not been ly attempted due to difficulties associated with the large inter-individual variations in the size and shape of these ankle bones.

Therefore, quantitative information about degenerative patterns of osteophyte formation or bone resorption of the ankle bones due to ankle OA has been largely unexplored. Given this situation, we recently proposed a method to quantify and visualize stereotypical patterns of bone degeneration occurring in OA tali 8. In that study, we suggested that left—right comparison of ankle bones in patients with unilateral ankle OA allows quantification and visualization of the patterns of bone degeneration occurring in ankle OA because the effect of the large inter-individual variabilities in the bone morphology can be eliminated, since left and right tali of healthy human are basically symmetrical 9.

By applying this method, the study successfully visualized and quantified the stereotypical patterns of degeneration occurring in OA tali. However, in our study, the degenerative patterns of the distal tibias and fibulas in ankle OA were not investigated.

In the present study, therefore, the aim was to visualize and quantify three-dimensionally the patterns of morphological degeneration of the distal tibia and fibula in patients with varus ankle OA by the left—right comparison of the bones in patients with unilateral ankle OA. Specifically, we tested if the left—right surface deviations of the tibia and fibula Free Connecticut sex classified unilateral varus ankle OA patients are ificantly larger than those of healthy humans. It has been reported that there is a slight left—right asymmetry in the human tibia and fibula 10but if the surface deviations in the unilateral varus ankle OA patients are ificantly larger than the surface deviations due to this inherent asymmetry in healthy humans, we can firmly conclude that the extracted surface deviations in the patients are due to degeneration in ankle OA.

Based on the plain radiographs, 22 patients in the OA group were found to be in stage 3a, 3b, or 4 on the OA side and in stage 1 or less on the opposite non-OA side, according to the Takakura classification. The s of patients classified into each stage were five, eleven, and six, respectively. Free Connecticut sex classified patients in the control group were not diagnosed as having ankle OA based on the CT findings. There were no ificant differences between the two groups in age and the sex ratio. Figure 1 shows the deviation color maps of two exemplary subjects within the control group.

Introduction

See text for more details. Three OA groups 3a, 3b, and 4 were pooled for statistical comparisons with the corresponding control. The amount of surface depression on the medial malleolus regions 4 and 5 was the largest, with a mean deviation of more than 2. Although the surface elevations on the anterior apophysis of the distal tibia regions 7 and 8 were large, with a mean deviation of more than 2 mm in severe varus ankle OA, the surface depression of the plafond except for the anterior area was relatively small, with mean deviation of less than 0.

The mean amounts of surface elevation on the anterior borders of the lateral malleolus and the distal tibiofibular t were approximately 1 to 2 mm in varus ankle OA with stage 3b and 4 regions 18, 19, 23, and 25 Figs. The amounts of left—right surface deviations in the OA and control groups at 26 regions of interest See Table 1 and Fig. Error bars indicate standard deviations.

The deviations are positive if the surface of the OA or right surface is outside the opposite non-OA or left surface, and negative if the surface is inside. The color map of the mean surface deviation in the OA group at the 26 regions of interest See Table 1. It was found that the surface depressions on the articular surface of the medial malleolus regions 4 and 5 were ificantly correlated with the surface depressions on the medial margin of the talar trochlea regions 2 in Seki et al.

Furthermore, there was a ificant correlation between the surface elevations on the anterior apophysis of the distal tibia regions 7 and 8 and the anterior margin of the talar trochlea region 4 in Seki et al. In addition, the surface elevations on the anterior edge and articular surface of the lateral malleolus region 18, 19, and 21 and the anterior edge of the distal tibiofibular articular surface region 23 and 25 were ificantly correlated with the surface elevation on the lateral articular surface of the talus region 11 in Seki et al.

studies have compared the morphological characteristics of the distal tibia and fibula between patients with varus ankle OA and healthy subjects by approximating the articular surface with a line on plain radiographs to quantify the inclination angles of lines 345 or with a circle on CT images to calculate the radii of circles 67. However, the extracted differences in these studies were not confined to true degeneration of the bones due to ankle OA, but they included possible morphological differences due to congenital inter-individual variations in size and shape of the bones.

In addition, these methods approximating the articular surface with a line or a circle are too crude to express complex, uneven patterns of bony degeneration, such as osteophytes and surface depressions observed in ankle OA. In the present study, surface deviations of the left and right ankle bones in patients with varus ankle OA 8 were quantified three-dimensionally to successfully extract and separate genuine patterns of morphological degeneration of the distal tibia and fibula. The present study Free Connecticut sex classified that there exists a characteristic pattern of bone degeneration of the distal tibia and fibula in varus ankle OA, which has not been ly described based on plain radiographs.

Specifically, surface depressions on the anterocentral area of the articular surface of the medial malleolus and surface elevations on the anterior edge of the lateral malleolus were observed in varus ankle OA, but such bone degeneration was not observed in the control group.

Although these bony degenerations have been empirically observed during surgery, this study offered, for the first time, quantitative evidence showing that such stereotypical patterns of bone degeneration actually occurring in the distal tibia and fibula in patients with varus ankle OA. Understanding the pattern of the bone degeneration in ankle OA may contribute to clarifying the mechanism underlying the abnormality of ankle t kinematics in ankle OA. In the present study, the largest bone degeneration surface depression was found to occur on the articular surface of the medial malleolus in varus ankle OA.

In addition, this was found to be correlated with the bone degeneration of the medial margin of the talar trochlea. This fact possibly indicates that large repetitive stress had been concentratively applied to this region in patients with varus ankle OA causing deterioration and erosion of the t surface and development of OA If the t erosion happened, the corresponding t space width would increase and the stability of the talar mortise would decrease.

Axial loading of the human foot is known to result in eversion of the calcaneus and inertial rotation of the talus and tibia due to innate mobility of the human foot so-called tibio-calcaneal coupling 1213 If the t space width of the ankle mortise got larger, the talus would rotate larger in the direction of Free Connecticut sex classified rotation.

Several studies using weight-bearing CT have reported that the abnormal internal rotation of the talus in the axial plane was a characteristic pathological feature of varus ankle OA 15 The more internally rotated posture of the talus in varus ankle OA was possibly due to the characteristic pattern of surface depression of the articular surface of the medial malleolus. The present color map analysis also showed that surface depressions in the anterocentral area of the plafond occurred in varus ankle OA.

This is consistent with the report that the angle between the tibial shaft and the distal t surface plafond on the sagittal plane i. The present study also observed that surface elevations were produced on the anterior apophysis of the distal tibia, along with the surface elevation on the anterior area of the talar trochlea in ankle OA.

In patients with varus ankle OA, the talus is reportedly subluxated anteriorly by anterior shear force induced by dysfunction of the anterior talofibular ligament 3 These surface elevations, which may be attributed to osteophyte formations on the anterior apophysis of the distal tibia and on the anterior surface of the talar trochlea are likely produced by accumulation of large loading stress acting on the anterocentral talocrural articular surface as a result of the subluxation of the talus in varus ankle OA It must be noted, however, that this osteophyte formation, if marginal, may contribute to stabilizing the ankle t with antero-posterior hypermobility 19 The present study also demonstrated surface elevations on the anterior borders of Free Connecticut sex classified lateral malleolus and the distal tibiofibular articular surface in ankle OA.

This deviation corroborates our study showing that surface elevations were also produced on the lateral articular surface of the talus 8. Larger loading stress is possibly accumulated to the lateral side, but not the medial side of the trochlea in ankle OA during standing and walking, possibly to reduce pain due to damage to cartilage and subchondral bone on the anteromedial side of the talar trochlea 8.

The surface elevations might also be associated with abnormal distal tibiofibular t mobility in ankle OA. A CT study proposed that the fibula was more externally rotated in severe ankle OA 21possibly due to instability of the talus in the ankle mortise in the axial plane. The fibula rotates externally and the anterior width of t space is widened during external rotation of the talus at the distal tibiofibular syndesmosis 22 The overload of the syndesmosis due to excessive internal—external mobility may cause the osteophyte formation on the anterior borders of the distal tibiofibular t.

This should be confirmed in future research by comparative evaluation of the position of the fibula with respect to the tibia in ankle OA using weight-bearing CT This analysis has some limitations. The method in this study can be applied only to patients with unilateral ankle OA, not to patients with bilateral ankle OA, since comparison with the non-OA side was performed for quantification of degeneration of the distal tibia and fibula.

However, this is indispensable to visualize and quantify the pattern of morphological degeneration of the distal tibia and fibula while eliminating the effects of the large inter-individual variabilities of bone morphology. Secondly, the bone model reconstructed from CT scan should ideally have a better accuracy. However, the resolution of the CT scan in the present study is nearly the highest we can get if both feet are scanned at one time to minimize doses of Free Connecticut sex classified using a conventional medical CT scanner.

Therefore, this limitation should not have a major effect on the current. Thirdly, the subjects in this study include more females than males, although there was no ificant difference in the ratio of male to female between the control and the OA groups. Several studies have reported sex-related morphological variations in the tibia and talus 25 Imbalance in the of female and male participants may have influenced the outcome of this study. However, we believe that such effect of gender should be minor.
