为了评价股骨部件使用的不同材料和涂层的中期影响，我们前瞻性地使用2个几何形状相同的解剖型股骨柄进行了21例一期双侧全髋关节置换术，随机分配至两侧。一个股骨柄由Ti6Al4V合金制成，近端喷砂表面上有羟基磷灰石涂层，另一个股骨柄由TMZF™合金制成，除了电弧沉积钛表面涂层外，近端还有羟基磷灰石涂层。尽管我们发现7个喷砂股骨柄的涂层表面存在不透射线线延伸，而我们在弧形沉积钛股骨柄的情况下没有发现不透射线线延伸，但所有髋关节均显示出良好的临床和放射学结局，如最终随访时（平均术后5.5年）的X线片和骨矿物质密度所示。
To evaluate the mid-term effects of different materials and coatings used for femoral components, we prospectively performed 21 one-stage bilateral total hip arthroplasties using 2 anatomical stems which have identical geometries, randomized to side. One stem was made of Ti6Al4V alloy and had a hydroxyapatite coating on grit-blasted surface proximally, and the other was made of TMZF™ alloy and had a proximal coating of hydroxyapatite in addition to an arc-deposited titanium surface coating. Although we found extensions of radiopaque lines to the surface of coatings of seven grit-blasted stems whereas we found none in the case of the arc-deposited titanium stems, all hips showed excellent clinical and radiological outcomes as shown by radiographs and bone mineral density at the final follow-up, average 5.5 years postoperatively.
