“…Two correction surgeries of claw hallux including muscle transecting and interphalangeal joint fusion were simulated and compared using FE models. 37 The surgeries were demonstrated to restore hallux alignment, nevertheless, in some cases resulted in high pressure in metatarsal region.…”

“…37 A 3D FE model of the first metatarsophalangeal joint was developed and used to simulate suggested causes of hallux rigidus 27 including tendon and fascia tightness and bone geometry mismatch. The analysis showed that fascia tightness produced high stress on the articular cartilage which was demonstrated as a possible cause of hallux rigidus.…”

Complementary to experimental studies, computational biomechanics has become useful tool for the understanding of human foot biomechanics and pathomechanics. Its findings have been widely used for the evaluation of the effectiveness of surgical and conservative interventions. These models, however, were developed with a wide range of variations in terms of simplifications and assumptions on the representation of geometrical structures and material properties, as well as boundary and loading conditions. These variations may create differences in prediction accuracy, and restrict practical and clinical applications. This paper reviews the state-of-the-art technologies and challenges in computational model development, focusing on foot problem-specific models for the assessment of the effectiveness and accessibility of clinical treatments. The computational models have provided valuable biomechanical information for clinical applications but further investigations come with many challenges in terms of detailed and patient-specific models, accurate representations of tissue properties, and boundary and loading conditions. Multi-scale computational models are expected to be an efficient platform to fully address the biomechanical and biological concerns.

Flatfoot is a foot condition caused by the collapse of the medial arch of the foot, and it can result in problems such as severe pain, swelling, abnormal gait, and difficulty walking. Despite being a very common foot deformity, flatfoot is one of the least understood orthopaedic problems, and the opinions regarding its optimal treatment vary widely. In this paper, an FE model of a flatfoot is proposed that is based on CT measurements. Surface meshes of the bones and soft tissue were generated from CT images and then simplified to reduce the node density. A total of 62 ligaments, 9 tendons, and the plantar fascia were modeled manually. Volume meshes of the different components were generated and combined to form the completed flatfoot model. A dynamic FE formulation was derived, and a balanced standing simulation was performed. The model was validated by comparing stress distribution results from the simulation to experimental data.

“…Faculty of Health Sciences, Staffordshire University, Stoke-on-Trent, United Kingdom 30 can open the way for novel diagnostic techniques and novel methods for treatment 31 planning/optimisation which would significantly enhance clinical practice. Even though no integrated modelling system exists that could be directly used in the clinic 37 and considerable progress is still required, current literature includes a comprehensive 38 toolbox for future work towards clinically applicable finite element modelling.…”
