An in-shoe gait analysis device to measure the maximum shear stresses at the first metatarsal head
Recent research indicates that the shear stresses acting on a diabetic's foot are one of the major mechanical contributors to the high incidence of ulceration experienced by these patients. These stresses together with direct pressure are thought to have an effect on blood flow occlusion elsewhere …

Variation in the Modified First Metatarsal of a Large Sample of <em>Tapirus polkensis</em> and the Functional Implications for Ceratomorphs.
… This paper deals with variation of the first metatarsal, which in tapirs was reduced as an early adaptation for running and then retrofitted to serve as a special origin for flexors and adductors of the proximal phalanges. The first metatarsal connects the medial ankle with a posterior process …

La protusión digital y metatarsal: comparación entre mediciones clínicas y radiológicas y su correlación con el soporte de cargas en el área plantar
… si la evaluación de las protrusiones digitales y metatarsales mediante procedimientos manuales presenta la misma fiabilidad que los procedimientos radiológicos de evaluación. Por otro lado, también hemos estudiado si la fórmula metatarsal influye en las presiones que soporta la planta del pie en …

An investigation into the effect of customised insoles on plantar pressures in people with diabetes
… varying two insole design features, metatarsal bar position and cushion material, on plantar pressures. In the final study, associations were investigated between changes in plantar pressure with different customised insole designs and specific structural and biomechanical foot …

Effect of restricted growth rate and elevated levels of minerals and vitamins on feet and leg characteristics, soundness scores and metacarpal and metatarsal characteristics of growing boars
… lesions, soundness scores and metacarpal and metatarsal characteristics of growing boars was studied. Boars assigned to the dietary treatments at 5 wk of age were serially necropsied beginning at 120 d of age. Foot and leg characterization was carried out at four periods (35, 122, 209 and 290 …

El tratamiento funcional de las fracturas del metatarso como alternativa a los métodos terapéuticos convencionales.
… is that functional treatment for first and fifth metatarsal fractures is effective and may replace the conventional treatments, conservative and surgical. Since the publication of previous studies where principles of the functional treatment for metatarsal fractures -consisting in a full and …

Finite element analysis of pin positioning in Lapidus procedure for treating Hallux Valgus
… with the bone joint consisting of first metatarsal and cuneiform along with the fixation device. The dimensions of the model are taken similar to a prototype model of the foot. Static analysis was done to find the displacement between the first metatarsal and cuneiform with the …

Pressure distribution beneath the foot in sideslope walking
… and similar increases beneath the central metatarsals with downslope placement. These features were not apparent in the profiles returned by the second platform. For both platforms, however, the first metatarsal showed increased pressures with downslope placement but decreased pressures …

Variations in the insertions of the tibialis posterior muscle and the structure of the medial longitudinal arch
… and the post-dissection method (talus-first metatarsal angle). The insertion data were then compared to the arch measurements, as well as foot side, age, sex, and population group. There was a weak negative correlation between the talus-first metatarsal angle measurement and the presence of …

Experimental Testing and Numerical Investigation of Materials with Embedded Systems during Indentation and Complex Loading Conditions
… stress level and rate of stress increase in the Metatarsals and the injury risk in the foot between forefoot strike (FS) and rearfoot (RS) is evaluated and discussed. A detailed full parametric FE foot model is developed and validated. The deformation and internal energy of the foot and stresses …

Foot Deformity and Bone Strength in Charcot Neuropathic Osteoarthropathy
… and geometric bone strength indices in human metatarsals, as well as an ex vivo validation of ultimate loading strength using cadaver samples. Results in Aim 1 showed that BMD and indices of compressive, bending, and buckling strength were strong correlates of metatarsal ultimate strength. Aim …

Taphonomy of a Lance Formation(Maastrichtian, WY) Dinosaur Bonebed with a Focus on Tooth Traces
… similar nearby bonebed contained a tyrannosaurid metatarsal (HRS13997)that possessed numerous scores on the posterolateral surface near its ventral end. The presence of a <em>Knethichnus parallelum </em>tooth trace, the first known on a tyrannosaurid bone, allows for us to measure the widths of …

The design and cadaveric assessment of a new artifial first metatarsophalangeal joint replacement for the great toe
… of rotation for the proximal end of the first metatarsal bone, tension in the plantar aponeurosis, mobile bones in the arch, and weight-bearing by the first metatarsal. Previous prostheses used in FMTPJ arthroplasty are believed to be inadequate in that they do not restore at least one of these …

Predictors of Hallux Valgus: a study of heritability
… metatarsophalangeal joint angle. pes planus. metatarsal formula, digital formula and first ray neutral position were explored through the statistical analysis of the data obtained from the sample. ‘The results of analyses suggest that all of these variables are gender influenced, …

The Effects of Fatigue on Biomechanics of Soccer Shooting
… the femur, medial malleolus, and base of fifth metatarsal. Each participant completed a fatigue protocol that was taken 90 seconds. Participants were asked to complete five shooting trials prior to the fatigue protocol as the baseline (Time 0) and then five more times after completion of each …

Two-channel surface stimulation for the correction of drop foot.
… of switches under the heel, 1st and 5th metatarsal heads was used to assess the degree of inversion/eversion during walking. A simple controller was implemented to link the two-channel stimulation system and the foot posture sensor, with the objective of maintaining a target foot posture …

The effect of dietary pH and phosphorus source on performance, gastrointestinal digesta, bone characteristics and body composition in weanling pigs
… metacarpal and specific gravity of the fourth metatarsal were increased (P < .01) for pigs fed the DCP compared with DFP diets. Neither dietary pH nor phosphorus source influenced backfat or loin muscle area. These results suggest that maintaining the acidifity of the diet during the first 3 wk …
