The combined application of Titanium plates with stainless steel screws appeared interesting, making a more elastic plate available without the risk of screw fractures. 3 different combinations of Titanium und stainless steel implants were tested in the animal and on humans. A morphometric evaluation of the soft tissue (animal) gave similar good results for stainless steel implants as for the combination of Titanium and steel, while pure Titanium gave the best result. Atomic absorption tests (human) showed that in case of the Titanium/steel mixture only the stainless steel screws did corrode. Delayed fracture healing or mechanical instability always gave risk to more metal deposits in the soft tissue than primary bone healing. If the advantages of Titanium seem important and if the rigidity of stainless steel screws may not be missed, the combination of the two metals appears possible and without danger.
钛板与不锈钢螺钉的联合应用似乎很有意思，能制造出一种更具弹性的钢板，且不存在螺钉断裂的风险。在动物和人体上测试了3种不同的钛和不锈钢植入物组合。对软组织（动物）的形态测量评估显示，不锈钢植入物与钛钢组合的效果相似，而纯钛的效果最佳。原子吸收测试（人体）表明，在钛/钢混合物的情况下，只有不锈钢螺钉发生了腐蚀。延迟骨折愈合或机械不稳定总是比一期骨愈合更容易导致软组织中出现更多的金属沉积。如果钛的优势似乎很重要，且不锈钢螺钉的刚性不可或缺，那么这两种金属的组合似乎是可行的，且没有危险。
