Abstract: Within the framework of self-consistent cranked Hartree-Fock-Bogoliubov theory (one dimensional) we predict a second backbend in the yrast line of ${}^{182}\mathrm{Os}$ at $I\ensuremath{\approx}40\ensuremath{\Elzxh}$, which is even sharper than the first one observed experimentally at $I\ensuremath{\approx}14\ensuremath{\Elzxh}$. Around such a high spin the structure becomes multiquasiparticle type, but the main source of this strong discontinuity is a sudden large alignment of ${i}_{13/2}$ proton orbitals along the rotation axis followed soon by the alignment of ${j}_{15/2}$ neutron orbitals. This leads to drastic structural changes at such high spins. When experimentally confirmed, this will be observed for the first time in this mass region, and will be at the highest spin so far.
