This article presents the case of an 82-year-old male patient with an implanted spinal cord stimulation system, who presented to our premedication consultation for a planned knee joint replacement. Spinal anesthesia was preferred because of the previous illnesses. In accordance with the recommendation of the treating pain physician for the puncture site, an uncomplicated L4/5 puncture was performed, and the surgery was performed with the patient under adequate spinal anesthesia.

In contrast intramedullary nailing of distal tibia fractures is accompanied by problems like decreased biomechanical stability. Nevertheless the indications for intramedullary nailing have been extended to include even more distal fractures.

Methods: Eight pairs of fresh, frozen porcine tibiae were used for this study. The expert tibial nail (Synthes) was equipped with either conventional locking screws (CL) or the angle-stable locking system (AS).
The treatment of osteoporotic distal femur fractures is still an unsolved problem of trauma surgery. The poor bone stock often leads to secondary loss of reduction and implant failure. Therefore, the development of new implants and their biomechanical testing is essential.

Since human bones vary markedly in density and geometry their suitability for biomechanical testing is limited. In contrast artificial bones are of great uniformity and therefore appropriate for biomechanical testing.
