Aim: The literal knowledge about the configuration of the radial bone is rare. Radial bone is investigated anatomically by computerized tomographic methods in this study.

Patients and Methods: Twenty-one cleaned and dried cadaveric bones were used for this investigation. The measurements were done on the diaphyseal, proximal and distal metaphyseal CT sections of the bone. A tortional angle was defined. The repetetive measurements were done by two different researchers on the same sections in different times. The interclass and intraclass correlation coefficients were analysed.

Results: The mean measurement of the radial tortional angle was 73 degrees [between 59° to 86°]. The ICC value between the initial measurements of the observers was, 9990 and considered torsion to be significant. (p< 0.001)

The ICC value between the secondary measurements of the observers was,9980 and considered torsion to be significant. (p< 0.0001)

The ICC value between the both measurements of the first observer was,9975 and the found torsion to be significant. (p< 0.0001)

The ICC value between the both measurements of the second observer was,9956 and the found torsion to be significant. (p< 0.0001)

Conclusion: This method is useful for evaluating the rotational alignment of the radial bone and rotational motion restruction of the forearm after fracture healing. It can also be used to predict the potential of remodelling of the radial bone in pediatric forearm fractures.
