Abstract: An underride protection device for passenger vehicles, in particular all-terrain vehicles, which is placed below longitudinal chassis beams and in front of a sub-frame or cross member as an additional crash plane, includes a two-dimensionally extensive element delimiting the vehicle towards the ground, at least one member extending in a transverse direction of the vehicle and two lateral members extending in a lengthwise direction of the vehicle, first coupling elements for connecting interior portions of the two-dimensionally extensive element to the sub-frame or cross member, and second coupling elements for rigidly connecting exterior portions of the two-dimensionally extensive element to the longitudinal chassis beams. In vehicles whose longitudinal chassis beams are arranged at a high level, the underride protection device with its integrated crash beam provides a compatibility of the impact zones for protecting the occupants of a struck vehicle.

Abstract: The invention relates to use of ibandronic acid (1-hydroxy-3-(N-methyl-N-pentyl)aminopropyl-1,1-diphosphonic acid) or physiologically compatible salts or esters thereof for improving the osseointegration of cement-free anchored endoprostheses. Ibandronate or salts thereof is applied for a short time immediately after insertion of an endoprosthesis, with the surprising result that secondary stability of the implant is obtained in only 5 weeks or less after the operation.
