摘要

目的：评价超高分子量聚乙烯（UHMWPE）原型材料在髋关节置换术中的可行性。材料和方法：我们使用了34个超高分子量聚乙烯试样进行测试，并制定了一个测试程序，包括试样几何参数的输入控制、摩擦技术测试、衬垫表面状况和圆度偏差的评估。结果：标本几何参数输入控制呈现异质性。具有负值（Dc-Dh）的超高分子量聚乙烯试样摩擦学试验失败。值（Dc-Dh）在0.6 ~ 0.8 mm范围内的试件T矩值较其他试件低。结论：75%的UHMWPE原型衬垫适合于关节置换术。

[Testing of friction node simulators for hip prostheses].

Objective: To estimate advisability of prototypes of ultra-high molecular weight polyethylene (UHMWPE) in hip arthroplasty.

Material and methods: We used 34 UHMWPE specimens for tests and developed a test program consisting of incoming control of specimen geometrical parameters, tribotechnical tests, assessment of liner surface condition and deviation from roundness.

Results: Input control of geometrical parameters of specimens showed their heterogeneity. UHMWPE specimens with negative value (D_c-D_h) failed tribotechnical tests. Specimens with value (D_c-D_h) within 0.6-0.8 mm demonstrated lower value of T moment compared to other specimens.

Conclusion: About 75% of UHMWPE prototype liners are suitable for arthroplasty.
