From September 1980 to March 1985, 123 cementless, polyethylene Endler acetabular sockets of the threaded, tapered type were implanted in 115 patients at the department of orthopaedic surgery, Balgrist, University of Zurich. The first 102 Endler sockets, in combination with a Zweymüller femoral prosthesis, have been followed up till April 1988, this corresponding to an average observation period of 57.4 months. 12.8% of the total number of qualitative criteria and the Sutherland method, and further 20.6% of the cases were suspected of having loosened, so that a figure of 33.3% (34 loosened sockets) resulted. A definite correlation between loosening and the following factors were determined: females, limping, Trendelenburg sign, period of implantation and severe, continuous pain. No correlation was found between either tolerable pain, age, weight, or para-articular ossification, and loosening. The cementless artificial hip joint of Endler/Zweymüller combination led to a definite improvement of independency and living quality through increase in mobility and reduction of pain.
1980年9月至1985年3月期间，苏黎世大学巴尔格里斯特骨科对115例患者植入了123个螺纹锥形无骨水泥聚乙烯恩德勒髋臼杯。前102个恩德勒髋臼杯与茨韦米勒股骨假体配合使用，随访至1988年4月，平均观察期为57.4个月。根据定性标准和萨瑟兰方法，总数的12.8%以及另外20.6%的病例被怀疑出现松动，因此松动率为33.3%（34个髋臼杯松动）。确定了松动与以下因素之间存在明确关联：女性、跛行、臀中肌步态、植入时间以及严重持续疼痛。在可耐受疼痛、年龄、体重或关节周围骨化与松动之间未发现关联。恩德勒/茨韦米勒组合的无骨水泥人工髋关节通过提高活动能力和减轻疼痛，显著改善了患者的独立性和生活质量。
