In surgery of fractured long bones, a patient suffering from osteoporosis represents constant challenge to a surgeon and applied material and instruments that need to destroy as little as possible of an already damaged bone. One potential way of increasing the contact surface between the implants and osteoporotic bone is injection of bone cement (methyl-metacrilat, Palakos) into a prepared scre...

have large errors, are in complete agreement with the physical-region plots obtained by other authors" as well as our own I Fig. 7(a)j. The results given here support the general validity of the Chew-Low technique. They illustrate the strong statistical requirements to which a meaningful application of this technique is subjected; they also show that pole effects seen in the physical region are...

The inhibitory effects of the dormant spores, the germinating spores, the sporoderm-broken germinating spores (SBGS), and the lipids extracted from the germinating spores of Ganoderma lucidum on the growth of mouse hepatoma, sarcoma S-180, and reticulocyte sarcoma L-II cells were investigated, respectively. The dormant spores could be activated by germination, and thus the bioactivities of the ...

  During fixation of a femoral neck fracture in a 23-year-old male patient with cannulated screws, a broken guide wire fragment inadvertently advanced through the hip joint and protruded into the pelvis. A second surgical approach was needed to remove the broken fragment from the pelvis. Awareness of such a potentially devastating complication will make surgeons more cautious during implementa...
