چکیده
UNLABELLED To identify the mean normal length of the metatarsals and the most common metatarsal formulas through a simple measurement method, thereby providing surgeons with data for planning treatment on symptomatic individuals with biometric abnormalities of the foot. METHODS We evaluated and measured dorsoplantar weight-bearing radiographs of normal adult feet (83 males and 83 females). RESULTS We found relative mean lengths for metatarsus I of 125.4 mm for males and 115.1 mm for females; for metatarsus II, 127.8 mm for males and 117.3 mm for females; for metatarsus III, 123.4 mm for males and 113.5 mm for females; for metatarsus IV, 114.2 mm for males and 105.3 mm for females; for metatarsus V, 99.5 mm for males and 91.7 mm for females. The mean forefoot width was 87.1 mm for males and 80.8 mm for females. CONCLUSION Feet with index minus occurred most frequently in both sexes, although all three metatarsal formulas can be considered to be normal patterns. The mean normal pattern for males and females respectively was the following: metatarsus I 2.4 mm and 2.2 mm shorter than metatarsus II; metatarsus III 4.4 mm and 3.8 mm shorter than metatarsus II; metatarsus IV 9.2 mm and 8.2 mm shorter than metatarsus III; metatarsus V 14.7 mm and 13.6 mm shorter than metatarsus IV.

Comparison of ground reaction forces and the amount of load introduced during crossover landing in people with flat foot and healthy individuals
Introduction: Investigating the risk factors during single crossover landing in people with flat foot complication is unknown. Therefore, the aim of the present study is to compare the ground reaction forces and the amount of load introduced during crossover landing in people with flat foot and healthy individuals. Methods: The study method is descriptive-comparative. Twelve male subjects w...
متن کاملComparison of Plantar Force, Pressure and Impulse During Walking in Men and Women With Flat Feet
Objective: This study aims to compare the variables of plantar force, pressure and impulse during walking in men and women with flat feet. Methods: The study population consists of non-athlete students with and without flat feet. Of these, 48 (male and female) were selected as study samples. The peak pressure, force and impulse on the foot were measured during walking by a foot scanner at a sa...
متن کاملAnalysis of the plantar pressure distribution in children with foot deformities.
This paper describes the method of measuring and assessing the pressure distribution under typical feet and the feet of patients with deformities such as: planovalgus, clubfoot, and pes planus using a pedobarograph. Foot pressure distribution was measured during static and walking at individual normal walking speed. Time-series pressure measurements for all sensors were grouped into five anatom...
متن کاملNormal Values of Metatarsal Parabola Arch in Male and Female Feet
There is not any method to measure metatarsal protrusion in the whole metatarsal. The aim of this research is to know the normal metatarsal parabola in male and female feet. The system of measurement devised by Hardy and Clapham to evaluate the protrusion between metatarsals I and II was adapted to study the whole metatarsal parabola and applied to the five metatarsals of 169 normal feet, 72 fe...
