“…Of note, there is a lack of prenatal screening for clubfoot in the Middle East as witnessed by the response of the POS, who are expected to be working in tertiary referral centers in their respective countries. Raising awareness about clubfeet among our colleagues gynecologists in the Middle East is still needed, especially that screening for clubfoot and possible associated conditions is feasible (4,52,53). Available evidence suggests that false positive rate can be lowered to around 10% if the diagnosis is performed in the second trimester (54,55).…”

“…This is of paramount importance as parents can be prepared for the diagnosis, and counselled for the disease, the presence (or not) of associated conditions and the path of the treatment, before birth of their awaited child (54,56). They will also be oriented to seek care as soon as possible after birth increasing the chance of presenting optimal care for their children (52,53,56). Much work is still to do on these aspects as people awareness on this condition is very poor (33).…”

Clubfoot is the most frequent congenital deformity involving the foot. Little is known about the management of this disease in the Middle East as sparse data is available in the literature. Through the last 5 decades, congenital clubfoot management in the Middle East went from manipulation through Kite's technique in the late seventies, to early primary surgical intervention in the late eighties and early nineties of the previous century, and then back to manipulation with Ponseti's technique and the French functional technique in the late nineties, with the latter falling out of favor with time. This is comparable to the evolution of management witnessed in the United States and in Europe, with 10 to 15 years of delay.The delay is getting shorter with time due to the easier access to published scientific data and the increasing number of fellows from Middle East travelling to referral centers in Europe and the USA. A survey was performed among pediatric orthopedic surgeons in the Middle East to assess their approach to clubfoot management. This is the first survey of its kind in the region. It showed a wide adoption (97.1%) of the Ponseti's technique with serial manipulation and casting, Achilles tenotomy followed by abduction bracing. Divergent practices were found concerning the upper age limit for Ponseti treatment and the setting of the Achilles tenotomy. Nevertheless, these subjects are still a matter of debate in the literature and international conferences. All in all, pediatric orthopedic surgeons in the Middle East are offering their patients the gold standard of care. However, lot of work is to be done in raising awareness for this disease in the community, and among our colleagues as prenatal screening for clubfoot in the Middle East is practically nonexistent.

“…The criteria for the diagnosis of clubfoot were established at the very beginning of the fetal ultrasound era, when Benacerraf and Frigoletto described five cases of prenatal ultrasound diagnosis of clubfoot in 1985 14 . Since then, numerous studies have clarified the significance of this anomaly as a possible tip of the iceberg for other more severe conditions: a recent statement from the Society for Maternal and Fetal Medicine has clearly summarized the state of the art 15 …”

Congenital isolated clubfoot: Correlation between prenatal assessment and postnatal degree of severity

et al. 2020

Objective: Since prenatal diagnosis of isolated clubfoot has a false positive rate (FP) of 10%-40%, fetal parameters that might correlate with post-natal confirmation and grade of severity were investigated. Method: Retrospective analysis (2013-2019) of cases analysed with threedimensional multiplanar view. The following data were recorded: the angle between the long axis of foot and lower leg; width, length and width-to-length ratio (W/L) of the foot; tibia length and calf width (T/C) ratio. Severity after birth was assessed using the Pirani classification. Results: Diagnosis was confirmed in 45/53 neonates (84.9%, FP 15%). Values were higher for both angle and W/L in true vs false positive cases (median angle 100.4 versus 69.55 , p <.000; median W/L 0.53 vs 0.45, p = .001), no difference for T/C (3.77 vs 3.48, p = .8). The area under the curve for angle was 0.98 (CI 0.94-1.00), with a diagnostic cutoff of 84.7 (PPV of 100%, NPV of 66.7%). Median Pirani score, available for 33 neonates (73.3%) was 3 (IQR 3-4): only angle correlated with Pirani score (Spearman coefficient 0.36, p = .04) Conclusion: Measuring the angle between the foot and lower leg can reduce the FP rate of prenatal congenital clubfoot diagnosis and better predict the need for postnatal treatment.

“…The footprint shows that most of the sole is in contact with the ground and the surface area is larger than the average value. The flat appearance of the group makes it easy to identify patients in this posture [28]. The flat metatarsal foot and the navicular bone extend from the top of the medial malleolus to the first metatarsal base.…”

The number of layers of deep learning (DL) increases, and following the performance of computing nodes improvement, the output accuracy of deep neural networks (DNN) faces a bottleneck problem. The resident network (RN) based DNN model was applied to address these issues recently. This paper improved the RN and developed a rectified linear unit (ReLU) based conditional generative adversarial nets (cGAN) to classify plantar pressure images. A foot scan system collected the plantar pressure images, in which normal (N), planus (PL), and talipes equinovarus feet (TE) data-sets were acquired subsequently. The 9-foot types named N, PL, TE, N-PL, N-TE, PL-N, PL-TE, TE-N, and TE-PL were classified using the proposed DNN models, named resident network-based conditional generative adversarial nets (RNcGAN). It improved the RN structure firstly and the cGAN system hereafter. In the classification of plantar pressure images, the pixel-level state matrix can be direct as an input, which is different from the previous image classification task with image reduction and feature extraction. cGAN can directly output the pixels of the image without any simplification. Finally, the model achieved better results in the evaluation indicators of accuracy (AC), sensitivity (SE), and F1-measurement (F1) by comparing to artificial neural networks (ANN), k-nearest neighbor (kNN), Fast Region-based Convolution Neural Network (Fast R-CNN), visual geometry group (VGG16), scaled-conjugate-gradient convolution neural networks (SCG-CNN), GoogleNet, AlexNet, ResNet-50-177, and Inception-v3. The final prediction of class accuracy is 95.17%. Foot type classification is vital for producing comfortable shoes in the industry.
