24 patients underwent bilateral hip replacement, using the SROM modular system (Depuy Johnson & Johnson, MA, USA) with the porous-coated sleeve in one hip and an HA-coated sleeve in the other. 20 patients were followed for at least 4 years with clinical and radiographic evaluations. We found no difference between the two sides as regards the time of disappearance of thigh pain and hip scores. Radiographs showed a buttress sign in 18 HA-coated and 15 porous coated stems. There were no differences in the serial bone-remodeling pattern around the proximal sleeve and measurement of wear volume between the two groups. In the short- to medium-term, our findings support the view that the hydroxyapatite-coated femoral stem has no advantages over those with porous coating.
24例患者接受了双侧髋关节置换术，一侧使用SROM模块化系统（美国马萨诸塞州迪普伊强生公司）的多孔涂层套筒，另一侧使用羟基磷灰石涂层套筒。20例患者接受了至少4年的临床和影像学评估。我们发现，在大腿疼痛消失时间和髋关节评分方面，两侧没有差异。X线片显示，18个羟基磷灰石涂层柄和15个多孔涂层柄出现了支撑征。两组近端套筒周围的系列骨重塑模式和磨损量测量没有差异。在短期至中期，我们的研究结果支持以下观点：羟基磷灰石涂层股骨干相对于多孔涂层股骨干没有优势。
