“…[17,19] It may be explained why AITFL is injured more than the other ligaments in the ankle under external rotation load. Our findings in this study showed that talus instability and talus displacement may occur in AITFL injuries of the ankle.…”

“…This situation constitutes ankle stability and some patients may experience ankle pain while walking and doing some activity. [7,17] Post traumatic anterolateral instability due to an injured and torn AITFL results in anterolateral extorsion of the talar dome, and it may cause impingement syndromes of the ankle. Unstable ankles may lead to the formation of fibrosis granulation tissue.…”

“…Recently, the prediction of in vivo ankle strains was documented using a computational model driven by laboratory motion capture data. 27 The results of this study could potentially enable consideration of temporal torque-time data as a function of turf and shoe design as they relate to potential injury with respect to the ankle and knee.…”

Excessive rotational traction between the foot and the playing surface has been shown to increase the risk of athletic injuries to ligaments in the knee and ankle. It is not currently feasible to accurately determine the free torque generated at the shoe-surface interface utilizing live participants without an embedded force plate. The goal of the current research was to predict the free torques that developed at the shoe-surface interface during voluntary internal and external rotations of the body relative to a planted foot using an insole pressure measurement system. Six participants fitted with a shoe containing an insole pressure measurement device performed trials on an embedded force plate. A pressure sensor mask of specific sensors was determined based on the degree of linear correlation between sensor pressure and the free torque. Linear regression analyses were utilized to develop a General Linear Regression Model and Participant-Specific Linear Regression Models. The results of this study indicated that insole pressure technology, in conjunction with linear regression models, can be utilized to predict free torques generated at the shoe-surface interface during isolated rotational motions of the body with respect to a planted foot. Furthermore, Participant-Specific Linear Regression models may be more accurate in these predictions than a general model, based on a group of participants. When used with computational modeling, this technique might allow the investigation of strains produced in ligaments of the ankle and knee that are generated during internal and external rotations of the body with a planted foot on various turf surfaces outside a laboratory setting.

The paper presents the analysis of the load of lower limbs of occupants in the armoured military vehicle, which has been destroyed by detonation of the Improvised Explosive Device (IED) charge under the vehicle. A simplified model of the human lower limb focused on upper ankle joint was developed in order to determine the reaction forces in joints and load in particular segments during the blast load. The model of upper ankle joint, include a tibia and an ankle bone with corresponding articular cartilage, has been developed. An analysis of the stress distribution under the influence of forces applied at different angles to the biomechanical axis of a limb has been performed. We analyzed the case of the lower limb of a sitting man leaning his feet on the floor. It has been shown that during a foot pronation induced by a knee outward deviation, the axial load on the foot causes significantly greater tension in the tibia. At the same time it has been shown that within the medial malleolus, tensile stresses occur on the surface of the bone which may lead to fracture of the medial malleolus. It is a common case of injuries caused by loads on foot of passengers in armored vehicles during a mine or IED load under the vehicle. It was shown that the outward deviation of the knee increases the risk of the foot injury within the ankle joint.Keywords: Large deformation, Finite element modeling, lower limb injury, upper ankle joint, military vehicle, explosion W artykule przedstawiono analizę MES obciążenia kończyn dolnych osób w opancerzonym pojeździe wojskowym, który został zniszczony przez zaimprowizowaną detonację ładunku wybuchowego (IED) pod pojazdem. W uproszczonym modelu dolnej kończyny ludzkiej skoncentrowano się na górnej części stawu skokowego. Model opracowany został w celu określenia siły reakcji w stawach i obciążenia w poszczególnych segmentach podczas obciążenia wybuchowego. Model górnego stawu skokowego, obejmuje kość piszczelową oraz kości stawu skokowego z odpowiadającymi chrząstkami stawowymi. Przeprowadzono analizę rozkładu naprężeń pod wpływem sił wywieranych pod różnymi kątami w stosunku do osi biomechanicznej kończyny. Przeanalizowano przypadek kończyny dolnej siedzącego mężczyzny z nogą opartą na podłodze. Wykazano, że podczas skręcenia stopy indukowanego przez odwiedzenie kolana na zewnątrz, siła osiowa na stopie powoduje znacznie większe naprężenie rozciągające w kości piszczelowej. Jednocześnie wykazano, że w kostce przyśrodkowej, naprężenia rozciągające występują na powierzchni kości, co może prowadzić do wystąpienia złamania kostki przyśrodkowej. Jest to częsty przypadek obrażeń spowodowanych obciążeniami stóp pasażerów pojazdów pancernych podczas eksplozji miny lub wybuchu ładunku ( IED) pod pojazdem. Wykazano, że odchylenie kolana zwiększa ryzyko obrażeń stopy w stawie skokowym.
