IntroductionClubfoot, mainly CTEV, is a complex three-dimensional deformity challenging physicians from ancient times. Among a thousand babies born, one to six suffer from clubfoot deformity; that is, in India alone, around 35,000 need treatment for clubfoot annually. This review summarizes the various practices of clubfoot assessment, noninvasive treatment, and engineering aspects of clubfoot treatment. The shortcomings of assessment methods and challenges with implementation of treatment methods are also presented.MethodsA narrative review of all related research papers available to authors was carried out.ResultsVarious clubfoot assessment methods have been developed to help physicians understand the severity of the problem and predict treatment parameters. The Pirani score and Dimeglio score are used predominantly for the assessment of deformity. However, these methods suffer from implementation-related limitations. Noninvasive methods, namely, Kite's method, functional physiotherapy method, and Ponseti method, are used in practice for treatment. The Ponseti method is the most popular with parents and physicians and is considered the gold standard for the treatment of clubfoot. However, it also suffers from various implementation issues, like treatment cost and lack of experts, particularly in low- and middle-income countries (LMICs). Engineers are using various technologies like computer-aided design (CAD)/computer-aided engineering (CAE) and additive manufacturing for modeling and analysis of clubfoot. Engineers have also attempted to develop corrective and maintenance orthosis for CTEV treatment.ConclusionsBecause newer and newer technologies are becoming accessible for interdisciplinary use, there is a need to apply contemporary technologies, especially to develop a corrective orthosis so that the current challenges of clubfoot assessment and treatment are addressed. The corrective orthosis should be based on Dr Ponseti's insights into clubfoot biomechanics.Clinical RelevanceThere is a need to explore contemporary technologies like data acquisition and CAD/CAE to address CTEV assessment–related issues. A corrective orthosis based on the understanding of the foot biomechanics for treatment can solve the various implementation-related challenges of the Ponseti method, particularly in low-resource settings.

“…Finite element modeling can potentially be used in many experimental studies. At present, it is widely applied in various branches of medicine [11][12][13], including orthopedics, cardiovascular surgery, and dentistry [13]. For considering food-grade applications, a high-pressure extractor was designed and analyzed using FEA.…”

Finite Element Simulation Tests of the Structural Strength of the Molding Module for Burger Production from Vegetable Outgrades

The aim of the study was to assess the stresses of the structural materials of the forming module in the process of burger production from vegetable outgrades. The simulation research object was a virtual CAD 3D model of a device used for forming multi-vegetable products. Strength tests were performed on the computational model by applying the finite element method. The following were analyzed in the model: the forces exerted by the mixture of vegetables on the side walls of the tank and the dosing unit; the force from the servomotor resulting from the horizontal thickening of the vegetable mixture; the force from the servomotor resulting from the vertical mixing of the vegetable mixture; the force from the die assembly actuator; the force caused by punching the actuator from the die assembly. For evaluating the structure in the scope of the study, it was assumed that safely reduced stresses should be taken into account, with a safety factor equal to 1.1 of the yield strength of the parent material from which the structure was made (steel 1.4301 (304) with a yield stress Re0.2 of 230 MPa). For welds, safely reduced stresses should be taken into account, with a safety factor equal to 1.4 of the yield strength (Re0.2 of 230 MPa). Strength analyses confirmed that the permissible stress levels were not exceeded in the molding module.
