We reviewed 78 patients with Hylamer acetabular liners (DePuy-Dupont Orthopedics, Warsaw, IN), with a mean follow-up of 3.8 years (range, 2-6 years), for signs of osteolysis secondary to polyethylene wear. Nine patients (11.5%) showed osteolysis greater than 1 cm2. One patient had a greater trochanter fracture through a lytic area, one patient required a revision at 4 years for severe acetabular and femoral lysis with lesser trochanter fracture, and a second patient is awaiting revision.
我们回顾了78例使用Hylamer髋臼内衬（美国印第安纳州华沙市迪普伊-杜邦骨科公司）的患者，平均随访3.8年（范围为2至6年），以观察聚乙烯磨损继发骨溶解的迹象。9例患者（11.5%）出现骨溶解面积大于1平方厘米。1例患者通过溶骨区域发生大转子骨折，1例患者在4年时因严重髋臼和股骨骨溶解伴小转子骨折而需要翻修，另1例患者正在等待翻修。
