摘要: The hook (32) comprises a body (33) and laminar portion (37) which is suitably profiled adapted to penetrate foramen opening at the base of occiput against it bears. arranged receive an osteosynthesis rod or plate has plane symmetry (P). curvature thickness occipito-cervical shell inclined relative one side other (P) so as be adaptable anatomy edge in region foramen. This inclination may for example substantially 45°. asymmetry enables surgeon avoid having previously remove piece patient consequently damage occiput.
