The Synergy stem is a third-generation proximal in-growth, tapered titanium alloy uncemented stem, with standard and high offset versions. Two hundred ten primary hip arthroplasties were performed using the Synergy stem in 193 patients. There were 124 males and 69 females with an average age of 58 years (range, 22-85 years). The average follow-up was 75 months (range, 60-96 years). Only 1 stem has required revision, for a stem survival rate of 99.5%. The overall incidence of thigh pain was 2.8%. Intraoperative undisplaced fractures of the proximal femur occurred in 3.3% of patients and were managed at the time with wiring, with no effect on outcome. Minor osteolysis was seen proximally in 10% of patients, but no osteolysis was seen distal to the porous coating.
Synergy股骨柄是第三代近端骨长入型、锥形钛合金非骨水泥股骨柄,有标准偏移和高偏移两种型号。在193例患者中使用Synergy股骨柄进行了210例初次髋关节置换术。其中男性124例,女性69例,平均年龄58岁(范围22 - 85岁)。平均随访75个月(范围60 - 96个月)。仅1例股骨柄需要翻修,股骨柄生存率为99.5%。大腿疼痛的总体发生率为2.8%。3.3%的患者术中发生股骨近端无移位骨折,当时采用钢丝固定处理,对预后无影响。10%的患者近端可见轻微骨溶解,但在多孔涂层远端未见骨溶解。
