ABSTRACT
Abstract Objective The present study aims to describe a new weightbearing radiographic method to visualize the heads of the five metatarsals on the coronal plane, evaluating their accuracy through intraclass correlation coefficients. Methods The subjects were evaluated, with weightbearing, with the ankle at 20 degrees of plantar flexion and the metatarsophalangeal joints at 10 degrees of extension, positioned on a wooden device. Two independent foot and ankle surgeons evaluated the radiography, with one of them doing it twice, at different moments, achieving an inter and intraobserver correlation, with intraclass correlation coefficients. Results We radiographed 63 feet, achieving an interobserver correlation coefficient of the radiographic method for the metatarsal heads heights in the coronal plane of the 1st, 2nd, 3rd, 4th, and 5th metatarsals of, respectively, 0.90, 0.85, 0.86, 0.83, 0.89. The intraobserver correlation coefficient were, respectively, 0.95, 0.93, 0.93, 0.86, 0.92. Conclusion Those correlations demonstrate that the method is accurate and can be used to investigate metatarsal head misalignments in this plane.
Resumo Objetivo Este estudo tem como objetivo descrever um novo método radiográfico com carga fisiológica para visualizar as cabeças dos cinco metatarsos no plano coronal. Métodos Os indivíduos foram radiograficamente avaliados com carga, com o tornozelo a 20º de flexão plantar e as articulações metatarsofalângicas a 10º de extensão, posicionadas em um dispositivo de madeira. As medidas foram aferidas por dois avaliadores independentes, sendo que um deles mediu em dois momentos distintos, obtendo a correlação inter e intraobservador, com o coeficiente de correlação intraclasses. Resultados Examinamos 63 pés, obtendo um coeficiente de correlação interobservador do método radiográfico para as alturas das cabeças dos metatarsos no plano coronal do 1º, 2º, 3º, 4º e 5º metatarsos de, respectivamente, 0,90, 0,85, 0,86, 0,83, 0,89. O coeficiente de correlação intraobservador foi, respectivamente, 0,95, 0,93, 0,93, 0,86, 0,92. Conclusão Essas correlações demonstram que o método é preciso e pode ser usado para investigar os desalinhamentos de cabeça dos metatarsos nesse plano.

We report a case of neurolimoma at the forfoot developed to him depends of the dorsalis pedis nerve at one girl, 12 old years presented a masse at the dorsal face of the forfoot, without any neurological symptom. The standard radiography is normal, RMI showed the tumour a long the nerve, was easy to remove without affecting the nerve. The anatomopathologic exam confirms a diagnosis of the neurilemoma and no neurological alteration occurred at the postoperative period. We didn't recover publications retuning a similar case
