ABSTRACT
SUMMARY

OBJECTIVE:

We conducted this study to define and measure the dorsal radial tilt, and to guide the reduction of distal radius fractures and the pre-bending of steel plates used in surgery.

METHODS:

The dorsal radial tilt was measured using both computed tomography (CT) and x-ray from both left and right side. The differences and correlations of the data measured by those two methods and from two sides were analyzed.

RESULTS:

The tilts measured by x-ray were significantly bigger than those measured by CT from the left side (t=55.51, p < 0.01) and from the right side (t=49.81, p < 0.01). The tilts measured by those two methods from the left and right sides were correlated (r=0.85, p < 0.01; r=0.81, p < 0.01). The dorsal radial tilts measured from the left side were not significantly different from those measured from the right side by CT (t=1.49, p > 0.05) and by x-ray (t=1.51, p > 0.05). The dorsal radial tilts measured from the left side by CT were significantly different from those measured from the right side by x-ray (t=43.07, p < 0.01), and these two sets of data were correlated (r=0.71, p < 0.01). The dorsal radial tilts measured from the left side by x-ray was significantly different from that measured from right side by CT (t=40.43, p < 0.01), and those two sets of data were also correlated (r=0.75, p < 0.01).

Conclusions:

The dorsal radial tilts measured from one side by one method can be used to estimate the tilts measured from the other side / the same side by the same method / the other method.
RESUMO
RESUMO

OBJETIVO:

Realizamos este estudo para definir e medir a inclinação radial dorsal, e para orientar a redução das fraturas do raio distal e a pré-flexão das chapas de aço utilizadas na cirurgia.

MÉTODOS:

A inclinação radial dorsal foi medida usando tomografia computadorizada (TC) e raios X dos lados esquerdo e direito. As diferenças e correlações dos dados medidos por esses dois métodos e de dois lados foram analisadas.

RESULTADOS:

As inclinações medidas por raios X foram significativamente maiores que as medidas pela TC do lado esquerdo (t=55,51, p<0,01) e do lado direito (t=49,81, p<0,01). As inclinações medidas por esses dois métodos dos lados esquerdo e direito foram correlacionadas (r=0,85, p<0,01; r=0,81, p<0,01). As inclinações radiais dorsais medidas a partir do lado esquerdo não foram significativamente diferentes das medidas do lado direito por CT (t=1,49, p>0,05) e por raios X (t=1,51, p>0,05). As inclinações radiais dorsais medidas a partir do lado esquerdo por TC foram significativamente diferentes das medidas a partir do lado direito por raios X (t=43,07, p<0,01), e esses dois conjuntos de dados foram correlacionados (r=0,71, p<0,01). As inclinações radiais dorsais medidas a partir do lado esquerdo por raios X foram significativamente diferentes das medidas do lado direito por CT (t=40,43, p<0,01), e esses dois conjuntos de dados também foram correlacionados (r=0,75, p<0,01).

CONCLUSÕES:

As inclinações radiais dorsais medidas de um lado por um método podem ser usadas para estimar as inclinações medidas do outro lado/o mesmo lado pelo mesmo método/o outro método.
