在翻修关节成形术的嵌塞移植术中,松质骨理想地重建成一个新的连续晶格。然而,有时可以使用生物活性因子来增强融合。本研究的目的是确定只有近端或远端松质骨体积的一半被融合的股骨撞击移植物结构的稳定性。与融合远端半部分相比,融合近端半部分的冲击移植物体积可获得更高的股骨干稳定性。这种近端移植物融合也导致了与整个移植物融合相似的茎稳定性。这些结果强调了近端固定撞击移植物股骨干的重要性。
In impaction grafting for revision joint arthroplasty, the morselized cancellous bone ideally remodels into a new contiguous lattice. However, the use of biologically active factors may sometimes be indicated to enhance fusion. The purpose of this study was to determine the stability of femoral impaction-graft constructs for which either only the proximal or distal half of the morselized cancellous bone volume was modeled as fused. Fusing the proximal half of the impaction-graft volume resulted in a higher femoral stem stability than did fusing the distal half. This proximal graft fusion also resulted in a stem stability that was similar to that of fusing the entire graft. These results emphasize the importance of proximal fixation of an impaction-grafted femoral stem.
