“…21 Computed tomography has been used to assess non-and partial weight bearing intertarsal relationship in flatfeet and normal feet; none of normal feet had subluxation, but subluxation increases on weight bearing in all flatfeet. 29 The AP-TC angle has weak correlation and thus is unreliable. 11 This angle is difficult to measure, as dorsoplantar radiographs are focused on the forefoot and exact bony axes are not clearly defined in AP radiographs.…”

purpose. To evaluate any correlation between various foot angles and their respective American Orthopaedic Foot and Ankle Society (AOFAS) scores for pain, and the effectiveness of a medial arch orthosis. Methods. 81 children with bilateral symptomatic flatfoot were randomised into orthosis (n=55) and control (n=26) groups. The orthosis group consisted of 33 male and 22 female patients aged 36 to 204 (mean, 99) months and they were given a medial arch support. The control group consisted of 15 male and 11 female patients aged 36 to 192 (mean, 100) months and they were managed with analgesics. Foot angles including anteroposterior (AP) and lateral talocalcaneal (TC) angles, AP and lateral talofirst metatarsal (TFM) angles, calcaneal pitch angle (in lateral plane), and talonavicular (TN) angle were measured, as were AOFAS scores for pain for the forefoot, midfoot, and hindfoot. improved significantly. In the controls, all AOFAS scores (except for the midfoot score) and only the AP-TFM angle improved significantly. In the orthosis group, the AOFAS hindfoot score correlated positively with the lateral TC angle of the left foot (r=0.345, p=0.010) and negatively with the calcaneal pitch angle of the right foot (r=-0.33, p=0.015). In the control group, the lateral TFM angle of the left foot correlated negatively with the AOFAS forefoot (r=-0.566, p=0.003) and midfoot scores (r=-0.497, p=0.001), whereas the calcaneal pitch angle of the left foot correlated positively with the AOFAS forefoot score (r=0.497, p=0.010). conclusion. Medial arch support orthosis significantly improved AOFAS scores and foot angles. Calcaneal pitch angle and lateral TC angle correlated well with AOFAS hindfoot scores.

“…Preoperative imaging evaluation has an important influence on surgeons' selection of the procedures. X-rays and computed tomography (CT) have been employed as the clinical image rating systems [5][6][7][8]. Radiographs taken under weight bearing have been reported to be useful for evaluation of stage II PTTD flatfoot deformity as well as preoperative planning of flatfoot corrective surgery [7,9].…”

“…Although previous studies have investigated internal arch height using radiography 7,21 and CT scans, 22 no studies could be located that have used ultrasonography as a noninvasive and inexpensive measurement tool for medial longitudinal arch height in either children or adults. The only published radiographic investigation of children's feet was a study of older children during weight bearing in which the obese participants displayed a lower internal arch height than their non-obese counterparts.…”

Are the feet of obese children fat or flat? Revisiting the debate

Objective: There is debate as to the effects of obesity on the developing feet of children. We aimed to determine whether the flatter foot structure characteristic of obese primary school-aged children was due to increased medial midfoot plantar fat pad thickness (fat feet) or due to structural lowering of the longitudinal arch (flat feet). Methods and procedures: Participants were 75 obese children (8.3±1.1 years, 26 boys, BMI 25.2±3.6 kg m À2 ) and 75 age-and sex-matched non-obese children (8.3 ± 0.9 years, BMI 15.9 ± 1.4 kg m À2 ). Height, weight and foot dimensions were measured with standard instrumentation. Medial midfoot plantar fat pad thickness and internal arch height were quantified using ultrasonography. Results: Obese children had significantly greater medial midfoot fat pad thickness relative to the leaner children during both non-weight bearing (5.4 and 4.6 mm, respectively; Po0.001) and weight bearing (4.7 and 4.3 mm, respectively; Po0.001). The obese children also displayed a lowered medial longitudinal arch height when compared to their leaner counterparts (23.5 and 24.5 mm, respectively; P ¼ 0.006). Conclusion: Obese children had significantly fatter and flatter feet compared to normal weight children. The functional and clinical relevance of the increased fatness and flatness values for the obese children remains unknown.
