The aim of this study was to analyze the survival of the Echelon® femoral stems in revision hip surgeries in patients with Paprosky I-IIIA femoral defects.
Sixty-six patients (70 hips) who underwent revision hip surgery with at least 3 years of follow-up data were included in the study between 2000 and 2013. The mean patient age was 64.5 (32-83) years, and the mean follow-up period was 93 (45-206) months. The reasons for revision were aseptic loosening in 55 (78.6%) patients, periprosthetic joint infection in 9 (12.9%) patients, periprosthetic fracture in 4 (5.7%) patients, and stem fracture in 2 (2.9%) patients. The preoperative and postoperative follow-up X-rays and functional scores were evaluated.
Five patients died in an average of 70 (45-86) months after surgery due to non-related diseases. We encountered sciatic nerve palsy in two patients and early hip dislocation in two patients, whereas 54 patients were able to walk without any assistive device. The remaining 12 patients required an assistive device to walk. The mean Harris hip score significantly increased from 34 (7-63) preoperatively to 72 (43-96) postoperatively. Aseptic loosening was observed in one patient. The survival of the porous-coated anatomical uncemented femoral stem was 98.4% over 10 years.
This study showed that good clinical outcomes and survival can be obtained when using porous-coated anatomical uncemented femoral stems.
本研究的目的是分析在患有Paprosky I-IIIA型股骨缺损的患者进行髋关节翻修手术时，Echelon®股骨柄的生存率。
2000年至2013年间，66例患者（70髋）接受了髋关节翻修手术，且有至少3年的随访数据纳入本研究。患者平均年龄为64.5（32-83）岁，平均随访期为93（45-206）个月。翻修原因包括55例（78.6%）患者为无菌性松动，9例（12.9%）患者为假体周围关节感染，4例（5.7%）患者为假体周围骨折，2例（2.9%）患者为柄部骨折。对术前和术后随访的X线片及功能评分进行了评估。
5例患者在术后平均70（45-86）个月因非相关疾病死亡。我们遇到2例坐骨神经麻痹和2例早期髋关节脱位，而54例患者能够无需任何辅助装置行走。其余12例患者行走需要辅助装置。Harris髋关节平均评分从术前的34（7-63）显著提高到术后的72（43-96）。观察到1例患者出现无菌性松动。多孔涂层解剖型非骨水泥股骨柄10年生存率为98.4%。
本研究表明，使用多孔涂层解剖型非骨水泥股骨柄可获得良好的临床效果和生存率。
