A 3D Geometric Morphometric Investigation of Relatedness in the Modern Human, Chimpanzee, and Homo naledi Postcranial Skeleton
… (first metacarpal (Mc1), proximal femur, talus, calcaneus, and navicular) from 187 individuals that were generated from surface scanners or downloaded from MorphoSource.</p><p>This dissertation employed a relatively new 3D geometric morphometric workflow that captures the entire shape of an …

Sex-Based Differences in Calcaneal Injury Tolerances Under High-Rate Loading
… were excised from the inferior surface of the calcaneus, and a small Dyna-Cast® pad was poured and sanded flat – interfacing with the exposed calcaneal surface. Each test specimen was mounted in a custom fixture and exposed once to high-rate axial loading characterized by a constant …

Insular adaptations in the appendicular skeleton of Sicilian and Maltese dwarf elephants
… morphology of the ankle-joint (especially the calcaneus' articular facet for the tibia). Furthermore, morphological similarities found between the femur of young continental elephants (P. antiquus and L. africana) and adult insular dwarfs (P. ex gr. P. falconeri and its probable ancestor …

Ontogeny and functional adaptation of trabecular bone in the human foot
… trabecular structure of the talus, calcaneus, and first metatarsal in samples from four archaeological populations. Trabecular structure is quantified in seventeen volumes of interest placed throughout the foot. Trabecular bone is influenced by a variety of factors including body …

Functional morphology of the anthropoid talocrural joint
… anteriorly oriented posterior talar facet on the calcaneus, have been hypothesized to reflect a greater emphasis on vertical climbing in anthropoids. This research evaluated these features in extant anthropoids, and compared them between pairs of taxa representing different emphases on climbing in …

Development and Application of a BioRobotic Simulation of Stance Phase Gait to Study Foot and Ankle Kinematics
… and translational and rotational data of the calcaneus, talus, and navicular from four cadaver specimens during stance phase gait. Specimens were mounted in the RTP with the tibia upright and foot flat on the baseplate. Passive loading applied a 5N ATL with no AT. Active ATLs were controlled …

Spatial mechanisms for modelling the human ankle passive motion
… structures of the ankle joint, namely the talus/calcaneus and the tibio/fibula bones at their interface, and the TiCaL and CaFiL ligaments. In order to show the accuracy of the models and the efficiency of the proposed procedure, these mechanisms are synthesized from experimental data and the …

Development Of Lower Extremity Injury Criteria And Biomechanical Surrogate To Evaluate Military Vehicle Occupant Injury During An Explosive Blast Event
… the 18 PMHS specimens sustained fractures of the calcaneus, talus, fibula and/or tibia. A tibia axial force of 2,650 N and impactor velocity of 8.2 m/s corresponds with a ten percent risk of an incapacitating injury. </p> <p>Currently available lower extremity biomechanical surrogates were shown …

Die Pilonfraktur : eine retrospektive Studie zur Erfassung von Spätresultaten nach operativer Versorgung
… Ruhigstellung und antiödematöse Therapie, die Calcaneusdrahtextension und der Fixateur-extern. 16 Patienten wurden primär definitiv osteosynthetisch versorgt, 67 in einem Intervall von durchschnittlich 15,9 Tagen, nach Weichteilkonsolidierung. 17 sehr weichteilkritischen Patienten, darunter 8 …

The role of external non-rigid ankle bracing in the prevention of inversion injuries
… thereby decreasing the rate at which the calcaneus inverts during a sudden inversion drop,3) to maintain this support, significantly, following sprinting and lateral movement exercise, and 4) to provide a relatively equal amount of ankle restriction of motion for both active males and …

A paleopathological and mortuary analysis of three Precontact burials from southern Saskatchewan
… and an abnormal peroneal process of the left calcaneus possibly related to an ankle injury such as a strain, and a possibly transacted fifth metacarpal. The association of the female and infant and the young age of the child may indicate that they both died due to obstetric problems, possible …

The design and cadaveric assessment of a new artifial first metatarsophalangeal joint replacement for the great toe
… plantar aponeurosis connect the hallux to the calcaneus. However, it is hypothesised that the particular orientation of the bones at the final stages of the stance phase is crucial to the weight-bearing functions of the FMTPJ. A specification for a new prosthesis was therefore developed in …

The Association between Bone Mineral Density, Lifestyle Factors, and Body Composition in a Fit College Population
… one standard deviation above young normal at the calcaneus and hip. There were significant gender and racial differences in baseline BMD at multiple skeletal sites. African American men had significantly higher hip, spine and heel BMD and greater tibial mineral content and cortical thickness than …

Bone turnover markers and prediction of bone loss in elderly women
Around 70,000 osteoporosis-related fractures occur in Sweden annually and approximately half of the women in western world will sustain a fragility fracture after the age of 50 years. Fracture preventive efforts require the identification of individuals who are at high risk. Biochemical markers of …
