“…The other form of stability for foot is provided by the presence of plantar aponeurosis, which takes up to 60% of the weight bearing and the action tie beam around 25% from the metatarsals. The toe extension during the normal gait cycle makes the plantar aponeurosis to become taut, thereby increasing the ability to withstand larger amount of stress [1,3].…”

“…The medial and lateral malleoli, talus, and tibial plafond make up the complicated joint of the ankle. The lateral ligaments, the deltoid ligament on the medial side, and the ligaments of the tibiofibular syndesmosis all work together to give ankle static stability in addition to the osseous architecture of the ankle mortise [2,3] . The primary ankle stabilizer is thought to be the deep deltoid ligament.…”

Background: Magnetic resonance image (MRI) was used with plain radiographic views for evaluation of bone and ligamentous injuries to detect any missing osteo-ligamentous injuries using single imaging modality. The purpose of this study was to ascertain the prevalence of associated ligamentous ankle injuries with an apparently isolated lateral malleolus fracture using MRI. Methods: This cross-sectional study was carried on 100 eligible patients with an acute isolated lateral malleolus closed fracture. Every patient underwent a history taking and clinical assessment (general and local assessment including inspection, palpation and neurovascular assessment of the affected lower limb) and full investigations. Imaging was done using Plain X-rays (anteroposterior, lateral, mortise and stress views) and MRI. Results: There was a significant relationship between the tenderness on medial side and Weber classification, Lauga Hansen classification and deltoid ligament injury (posterior tibiotalar ligament (PTTL), anterior tibiotalar ligament (ATTL) and tibiocalcaneal ligament (TCL)) (P value <0.001). There was an insignificant relation between radiographic anterior-posterior (AP) medial clear space (MCS) and (PTTL and ATTL), syndesmotic and Lateral collateral ligament injuries. There was a significant relationship between missed deltoid injuries with weber and Lauge. Hansen classification (P =0.005). Conclusions: MRI is valuable in the assessment of radiologically isolated lateral malleolus fracture cases. MCS in AP and stress views was insignificantly correlated to deltoid ligament injury, syndesmotic ligaments injury and lateral collateral ligaments injuries however, there was a strong link between syndesmotic ligaments injuries and both tibiofibular overlap (TFO) and tibiofibular clear space (TFCS) in AP and stress views.

“…Studying foot and ankle biomechanics is another major field in lower extremities research investigations which focuses on the function of the foot and ankle in the normative, pathologic, and clinically treated states ( Towers et al, 2003 ). Jiang et al developed a multi-rigid body modeling technique to analyze the kinetics and kinematics of the lower limb in the half-squat parachuting landing to evaluate the protective effects of an ankle brace.…”

Editorial on the Research Topic Advancements in biomechanical modeling of injuries, diseases, diagnoses, and treatments of lower extremitiesThe musculoskeletal system is a complex multi-articular structure which provides a relative range of motion for functional activities. It seems similarities between the joint biomechanics of the upper and the lower extremities. However, the upper extremity is more specialized for daily activities with greater ranges of motion, and the lower extremity structures are well prepared for locomotion and its weight-bearing (Yan et al., 2015). The basic principles of lower limb biomechanics focus on understanding the mechanical response and performance, the effect of injuries or diseases, and movement optimization in hope of finding effective rehabilitation procedures. Nevertheless, there is still a lack of knowledge in this research field, particularly at the level of injury risk factors, muscle functions, control, and instability. Hence, studying the biomechanical response of healthy, diseased, and treated lower extremities has been of great interest to clinicians and researchers. Numerous experimental, theoretical, as well as computational biomechanical studies have been conducted in the hope of understanding the underlying mechanisms involved in lower limb biomechanics. While some studies have been geared toward the prevention of injuries, others deal with more effective diagnostic and treatment modalities. Experimental clinical studies, using both in-vitro and in-vivo platforms, have the ability to provide relevant information regarding the biomechanical behavior and response of the lower extremities. Incidentally, these studies are essential but could be costly and limited by their inability to estimate the detailed microstructural phenomenon.In the past few decades, different mathematical and computational methodologies of modeling [such as musculoskeletal and finite element (FE) modeling] have emerged as powerful and practical tools for non-invasive biomechanical investigations. These modeling approaches can explore the various aspects of the lower extremities, from the response of the
