The Monk Duopleet femoral interlocking uncemented two-component endoprosthesis consists of a polyethylene cup covered by a metal cap and an Austin-Moore type stem. Seventy-two patients (average age, 71 years) were treated by this arthroplasty: 27 for subcapital femoral neck fracture, 36 for osteoarthritis, and nine as an exchange operation. Three patients died following operation. After a mean follow-up time of 50 months, 47 patients were reexamined clinically and radiographically. Because of loosening, four patients had the prosthesis removed. Twenty-six patients were classified as excellent, 12 as good, six as fair, and three as poor. There were no cases of acetabular intrusion. The Monk Duopleet prosthesis may solve the problem of the loosening that had been associated with femoral component alone. The long-term results are promising and appear to be better than the results of the standard Moore prosthesis. The Monk Duopleet prosthesis is an alternative to other two-component endoprostheses for the treatment of subcapital hip fractures and in the group of patients suffering from osteoarthritis, where an arthroplasty with a cemented prosthesis may be considered hazardous because of age or general disease.
蒙克双叶型非骨水泥型股骨双组件髋关节假体由一个覆盖有金属帽的聚乙烯髋臼杯和一个奥斯汀-摩尔型股骨柄组成。72例患者（平均年龄71岁）接受了这种关节置换术：27例为股骨颈头下型骨折，36例为骨关节炎，9例为翻修手术。3例患者术后死亡。平均随访50个月后，对47例患者进行了临床和影像学复查。因松动，4例患者取出了假体。26例患者评定为优，12例为良，6例为中，3例为差。无髋臼内陷病例。蒙克双叶型假体可能解决了仅与股骨组件相关的松动问题。长期结果令人满意，似乎优于标准摩尔假体的结果。对于股骨颈头下型骨折的治疗以及骨关节炎患者群体，蒙克双叶型假体是其他双组件假体的一种替代选择，在这些患者中，由于年龄或全身疾病，采用骨水泥型假体进行关节置换术可能被认为具有风险。
