Review
Talar body fractures are uncommon fractures of the foot and its management results to be very hard due to retrograde vascularization and wide articular cartilage coverage of talar surface, which could easily lead to poor functional outcomes, avascular osteonecrosis and early post traumatic arthritis. We describe a case of displaced, vertical, talar body fracture in a 41-year-old patient treated with reduction and fixation by talar anteromedial approach coupled to medial malleolar osteotomy to better expose the fracture. Our literature review has found few studies, in addition with a low level of statistical evidence. We advocate for more studies with a bigger sample and with a design of randomized control trials.

BACKGROUND & PURPOSE
Afferent input from the sole affects postural stability. Cutaneous reflexes from the foot are important to posture and gait. Lower-limb afferents alone provide enough information to maintain upright stance and are critical in perceiving postural sway. Altered feedback from propreoceptive receptors alters gait and patterns of muscle activation. The position and posture of the foot and ankle may also play an important role in proprioceptive input.Therefore, the current research aims to compare static balance and ankle and knee proprioception in people with and without flexible flatfeet.
METHODOLOGY
91 female students between the ages of 18 and 25 voluntarily participated in this study, of which 24 were in the flexible flatfoot group and 67 were in the regular foot group after evaluating the longitudinal arch of the foot. The position sense of ankle and knee joints were measured using the active reconstruction test of the ankle and knee angle; Static balance was measured using the Sharpened Romberg test. Data were non-normally distributed. Accordingly, non-parametric tests were applied. The Kruskal-Wallis test was applied to compare differences between groups in variables.
RESULT
Kruskal-Wallis test showed a significant difference between two groups of flat feet and normal feet in the variables of static balance and position sense of ankle plantarflexion, ankle dorsiflexion, and knee flexion (p ≤ 0.05). A significant correlation was found between static balance and sense of ankle and knee position in the group with normal feet. The analysis of the regression line also showed that ankle and knee position sense could predict the static balance score in the regular foot group (ankle dorsiflexion position sense 17% (R = 0.17), ankle plantarflexion position sense 17% (R = 0.17) and knee flexion position sense 46% (R = 0.46) explain of changes in static balance).
DISCUSSION & CONCLUSION
Flexible flatfoot soles can cause loss of balance and sense of joint position; therefore, according to this preliminary study, clinicians must be aware and should take into account this possible deficit in the management of these patients.

Review
PURPOSE
Although flatfoot is a widespread human condition, historical medical texts and ancient illustrations on this deformity are extremely rare. Nowadays, doubts regarding its management remain unsolved. This historical review aims to identify the presence of pes planus since the prehistoric era and examine the treatments proposed over the centuries up to the present.
METHOD
For this propose, we performed an extensive electronic search of the relevant literature, complemented by a manual search of additional sources from archaeological to artistic, literary, historical, and scientific accounts, describing flatfoot and its treatment in different eras.
RESULTS
Flatfoot accompanied the evolutionary timeline of human species: from Lucy Australopithecus to Homo Sapiens. It was described among various diseases suffered by Tutankhamun (1343-1324 B.C.), while the first anatomical description dates to Emperor Trajan (53-117 A.D.) and the medical studies of Galen (129-201 A.D.). It was also represented in the anatomical drawings of Leonardo da Vinci (1452-1519) and Girolamo Fabrici d'Acquapendente (1533-1619). Historically, the conservative treatment by insoles was the only one proposed until the nineteenth century. Since then, the most popular surgical procedures performed for correction have been osteotomies, arthrodesis, arthrorisis, and tendon lengthening and transfer.
CONCLUSION
During the centuries, conservative therapeutic strategies have not radically changed in their substance, while operative ones have become the protagonists during the twentieth century up to the present. Nevertheless, after more than 2000 years of history, there is no consensus regarding the best indication for the flatfoot and if it really needs to be treated.

Lateral column (LC) instability occurs in adult acquired flatfoot deformity (AAFD). Differential ligament contribution to LC stability is unknown. The primary aim was to quantify this by using cadaver sectioning of lateral plantar ligaments. We also determined the relative contribution of each ligament to dorsal translation of the metatarsal head in the sagittal plane. 17 below-knee cadaveric specimens, preserved by vascular embalming method, were dissected to expose plantar fascia, long/short plantar ligaments (L/SPL), calcaneocuboid (CC) capsule and inferior 4th/5th tarsometatarsal (TMT) capsule. Dorsal forces of 0 N, 20 N and 40 N were applied to the plantar 5th metatarsal head after sequential ligament sectioning in different orders. Pins provided linear axes on each bone, allowing relative angular bone displacements to be calculated. Photography and ImageJ processing software were then used for analysis. The LPL (and CC capsule) had the greatest contribution to metatarsal head motion (107 mm) after isolated sectioning. In the absence of other ligaments, sectioning these resulted in significantly increased hindfoot-forefoot angulation (p ≤ 0.0003). Isolated TMT capsule sectioning demonstrated significant angular displacement even when other ligaments remained intact (with intact L/SPL, p = 0.0005). CC joint instability required both LPL and capsular sectioning for significant angulation to occur, whilst TMT joint stability was largely dependent on its capsule. The relative contribution of static restraints to the lateral arch has not yet been quantified. This study provides useful information on relative ligament contribution to both CC and TMT joint stability, which may in turn improve understanding of surgical interventions used to restore arch stability.

The Journal of Maternal-fetal &... Dec 2023This study aimed to analyze the ultrasound characteristics of fetal congenital vertical talus (CVT) to provide a detailed basis for the prenatal diagnosis of CVT.
OBJECTIVE
This study aimed to analyze the ultrasound characteristics of fetal congenital vertical talus (CVT) to provide a detailed basis for the prenatal diagnosis of CVT.
METHODS
We retrospectively analyzed the ultrasonographic findings of fetuses with CVT confirmed by X-ray, surgery, or autopsy from 2010 to 2020. Clinical characteristics and ultrasonographic findings of CVT, including foot morphology, ossification center of the calcaneus and talus, associated deformities, and chromosomal test results, were recorded.
RESULTS
Thirteen patients diagnosed with CVT by prenatal ultrasound were confirmed postpartum. Nine cases were bilateral, and four were unilateral. Under two-dimensional ultrasound, 13/13 cases had abnormal foot morphology, and 10 of 13 cases (76.9%) showed that the ossification center of the talus moved downward, and the calcaneus moved laterally. Under three-dimensional ultrasound, 11 cases (84.6%) presented a "rocking chair" appearance, and two cases did not obtain satisfactory three-dimensional image due to oligohydramnios and fetal position. In this group of cases, two cases (15.4%) were isolated CVT, and the other 11 cases (84.6%) were complicated with other abnormalities. Eleven cases of non-isolated CVT and 1 case of isolated CVT were induced, and another patient with isolated CVT had undergone postnatal surgery, which had been followed up for 8 years and recovered well.
CONCLUSIONS
The combination of fetal foot morphology, ossification center position of the calcaneus and talus, and three-dimensional ultrasound can provide a reliable diagnosis of CVT. Furthermore, we should pay more attention to the evaluation of other systemic and chromosomal abnormalities in CVT cases.

Progressive collapsing foot deformity (PCFD) is characterized by a progressive subluxation of the peritalar bones and respective joints. Two-dimensional conventional radiographs are limited in their ability to visualize the peritalar bones and joints with adequate detail to describe the complex three-dimensional deformity. An improved understanding of the relationship between joint coverage and deformity would allow clinicians to use coverage analysis to distinguish among the stages of PCFD. The aim of this study was to analyze the joint coverage of the six articular relationships within the talocrural, subtalar, and Chopart joints using weightbearing computed tomography (WBCT) scans. Ten individuals with a flexible hindfoot and ten individuals with a rigid hindfoot presentation of PCFD were compared to twenty-seven asymptomatic control individuals. The three most relevant findings are: (I) the anterior-medial facet of the subtalar joint contains the greatest reduction in coverage for patients with a rigid deformity, (II) an increase in talonavicular overlap (TNO) moderately correlated with a decreased coverage in the: tibiotalar, anterior-medial subtalar, talonavicular joints, and (III) the calcaneocuboid joint lacks radiographic values to adequately quantify alignment and coverage. To conclude, there were significant differences in coverage area of various articulating regions throughout the hind- and midfoot when comparing PCFD patients to asymptomatic control individuals. Relevant radiographic measures correlating to articular coverage areas of clinical interest were identified, possibly helping to better quantify PCFD in clinical practice.
