In hadrontherapy, ion beams interacting with tissue-like materials undergo nuclear fragmentation processes. The experimental studies of the latter are fundamental for the optimization of the treatment planning systems (TPS). The interaction of the beam is modelled rescaling the data in water accordingly. This approximation might limit the accuracy of the TPS if the chemical composition of the traverse material differs significantly from water. For this reason, a dedicated study of the nuclear fragmentation processes of ${}^{12}$C ion beam interacting with bone target was performed. In this work, results on angular distributions and kinetic energy spectra of secondary fragments are presented.
