“…It is well-accepted that the prevalence of the hallux valgus and atfoot deformity is higher in women [9][10][11][12][13][14] and increases with age [13]. While the mechanism underlying these foot disorders remains unclear, recent studies suggested that sex-and age-related differences in the calcaneus morphology is possibly linked to higher prevalence of foot disorders in women and elderly [15,16]. If this is true, it is expected that there also exists sex-and age-related differences of the articular morphology of the talus, which is the keystone of the foot.…”

Background The high prevalence of foot pathologies in women and the elderly is suggested to be linked to sex-and age-related differences in the calcaneal morphology. Given that, it is expected that there also exists sexand age-related differences of the articular morphology in the keystone of the foot, the talus. The present study investigated the orientation and curvature of the three articular surfaces of the talus in relation to sex and age based on computer tomography (CT). Methods The CT images of 56 feet were used in this study. The orientations of the talocrural, subtalar, and talonavicular joints were quanti ed three-dimensionally by calculating normal and principal axes of the articular surfaces de ned by planar approximation. The curvature radii of the articular surfaces were also quanti ed by cylindrical and spherical approximations. Results The talonavicular surface was signi cantly more twisted and less internally rotated in females than in males. With aging, the subtalar articular surface was signi cantly facing more posteriorly. Moreover, it was found that the curvature radii of the trochlea and navicular articular surfaces signi cantly increased with aging, indicating the attening of the articular surfaces. Conclusion The sex-and age-related differences in talar articular morphology were observed. The substantial degeneration pattern of the talar morphology with aging could potentially lead to a higher prevalence of foot disorders in the elderly.

“…Our findings showed higher hindfoot valgus values in females similar to other parameters found in the literature, including sagittal curvature of the femoral condyle, 6 external tibial rotation, trochlear groove orientation, 23 excessive eversion of the foot, pedobarographic findings, and foot disorders. 8,14 However, our methodology and samples do not allow us to investigate sex differences as a causative factor of valgus deformities.…”

Background: Previous studies focusing on the effects of knee surgery on hindfoot alignment have suggested some degree of compensation between the knee and the hindfoot. However, these studies did not investigate a preoperative relationship in patients without end-stage knee osteoarthritis using 3-dimensional (3D) biometrics. The purpose of this study was to investigate the relationship between knee and hindfoot alignment using 3D weightbearing imaging. Methods: This retrospective comparative study included 95 lower limbs with weightbearing computed tomography and low-dose biplanar radiograph investigations. Cases with a history that may have caused a change in lower limb alignment were excluded. Hindfoot and knee alignments were measured using foot ankle offset (FAO) and hip-knee-ankle (HKA) angle, respectively. Patients were separated into 3 groups according to the knee deformity to investigate the distribution of FAO in each group. Results: The mean (SD) FAO was 2% (7%) for the knee varus group, 1% (6%) for the neutral knee group, and 4% (5%) for the valgus knee group ( P = .12). Fifty-three percent of patients with knee valgus showed a pathological hindfoot valgus ( P = .04). We found a positive but moderate correlation between hindfoot valgus and HKA (ρ = 0.53; P = .01). Female sex was associated with higher FAO (3% ± 4% vs 0.6% ± 6%; P = .009). Conclusion: This feasibility study suggests a new opportunity using 3D biometrics to understand the relationship between knee and hindfoot alignment and to highlight different patterns of combined deformities in further investigations. Level of Evidence: Level III, comparative study.

“…Due to plantar fat pad, the infant's feet appear flat; this fatty pad disappears between 2 and 10 years of age after developmental changes in the medial arch [2]. The anatomical manifestations of flattening or lowering of medial foot-arch are ligamentous laxity, equinus deformity, torsional deformity, vertical talus, and tarsal coalition, caused by multifactorial variables like overweight, obesity, type of footwear's, weak muscles that support the arch, foot injury, and congenital deformations [3][4][5][6]. Besides, many authors claim that flatter foot structure among obese school-aged children might be due to fat feet rather than the structural lowering of the arch (flat feet) and emphasized the need to include a larger sample of normal weight control participants to explain the association in the absence of imaging outcome measures [7][8][9].…”

Flatfoot and associated factors among Ethiopian school children aged 11 to 15 years: A school-based study

et al. 2020

View full text Add to dashboard Cite

Background The Foot health of a child plays a pivotal role in their participation in play, locomotive activities, healthy lifestyle, somatic development, and weight management. The burden of flatfoot among children in Ethiopia is not known. The objective of this study was to analyze the structure of the medial foot arch using Staheli plantar arch index and investigate its associated factors among larger sample school children, aged 11-15 years in Ethiopia.
