Medidas do tendão do calcâneo no primeiro ano de vida

Abstract

OBJECTIVE: To determine the thickness and width of the calcaneal tendon (Achilles tendon) in both male and female, eutrophic children at 2, 6, 9 and 12 months of age. MATERIALS AND METHODS: The present prospective and descriptive study included 38 boys and 31 girls. Measurements of the tendons were performed by means of ultrasonography, with a linear, 14-MHz probe, at the level of the medial malleolus. RESULTS: Tendon thicknesses observed in the boys were 2.4 mm, 2.3 mm, 2.4 mm, and 2.4 mm, respectively at 2, 6, 9 and 12 months. Widths were, respectively, 6.0 mm, 6.4 mm, 6.7 mm and 7.1 mm. In the girls, the tendon thicknesses observed at 2, 6 and 9 months were 2.4 mm, and 2.5 mm at 12 months. Widths were, respectively, 5.7 mm, 6.2 mm, 6.5 mm and 6.5 mm. CONCLUSION: No difference was observed in the calcaneal tendon thickness between boys and girls along the first year of their lives; however, width measurements demonstrated differences.

MATERIAIS E MÉTODOS: Fizeram parte deste estudo prospectivo e descritivo 38 meninos e 31 meninas. As medidas dos tendões foram obtidas por meio de ultrassonografia, utilizando transdutor linear de 14 MHz, na altura do maléolo medial. RESULTA-DOS: Verificou-se que as espessuras dos tendões nos meninos foram de 2,4 mm, 2,3 mm, 2,4 mm e 2,4 mm, aos 2, 6, 9 e 12 meses, respectivamente. As larguras do tendão do calcâneo foram de 6,0 mm, 6,4 mm, 6,7 mm e 7,1 mm, respectivamente. Nas meninas, as espessuras obtidas aos 2, 6 e 9 meses foram de 2,4 mm, e aos 12 meses encontrou-se o valor de 2,5 mm. As quatro medidas da largura foram de 5,7 mm, 6,2 mm, 6,5 mm e 6,5 mm, respectivamente. CONCLUSÃO: Não houve diferença na espessura do tendão do calcâ-neo ao longo do primeiro ano de vida para ambos os gêneros, entretanto, houve diferença nas medidas da largura.

Tendão de Aquiles: curvas de normalidade em crianças como possível marcador para hipercolesterolemia familiar

“…With respect to the morphometric study of the Achilles tendon and its possible relation with familial hypercholesterolemia, and therefore increased risk for cardiovascular diseases, the study developed by Bezerra et al (8) , "Measurements of the calcaneal tendon in the first year of life", published in the present issue, justifies the research in the absence of normality curves by age, weight, length and gender in the childhood, which in many occasions, makes the early diagnosis of some diseases more difficult. The authors report that "No study was found in the literature that have measured thickness and width of the calcaneal tendon in children up to 12 months of age" and, in fact, as usual in the academic community, little research has been dedicated for defining normality standards and variations, emphasizing the investigation of the diseases, particularly in our specialty.…”
