| Abstract: | Prebend compression plate fixation was examined by projective amplifier and light-elastic mechine according to biomcch nical principles. Animal experiments and clinical trial in 8 patients have been performed. The straight compression plate has a inherent defect of eccentric compression, the pre-bend plate can overcome this defect because of its elastic deformity. We found that the optimum prebend angle is about 4 degrees associated with 40 to 60 kg. force of compression. With this method, the fractured bone ends can be contacted tightly and compressed evenly, so that the internl af ixation would be more stable and the fracture healing enhanced. A "direct bone healing" was gained in our animal experiments. The result of clinical trial was satisfactory as predicted. This study makes the compression plate method more reasonable biomechanically. It has been verified in clincal trial, and might be recommented. |
