The Monk hard-top hip prosthesis has an acetabular cup of polyethylene, covered by a metal cap. The femoral stem is of two types, for insertion with or without acrylic cement. One hundred and sixteen patients of an average age of 78.5 years, who has sustained intracapsular fractures of the femoral neck of Garden type 3 of 4, were treated by Monk hard-top arthroplasty. After a mean follow-up time of 23.9 months (range 9-47 months), 73 survivors were re-examined clinically and radiologically. Using Love's classification it was found that in 34 cases (48 per cent) the result was excellent and in 21 cases (30 per cent) it was good. In 12 cases (17 per cent) the result was fair and in 4 cases (5 per cent) it was poor. The poor result in this latter-mentioned group was mainly due to medical diseases that interfered with walking. There was clinical and radiological evidence of an increased tendency of loosening of the uncemented prosthesis. Our numbers were, however, too small to draw definite conclusions about this. Our experience with the Monk hard-top endoprosthesis is satisfactory, but a longer time of observation will be required to establish whether this prosthesis is better than the conventional type for intracapsular fractures of the femoral neck.
蒙克硬顶髋关节假体有一个由金属帽覆盖的聚乙烯髋臼杯。股骨干有两种类型，可带或不带骨水泥进行植入。116例平均年龄为78.5岁、发生Garden 3型或4型股骨颈囊内骨折的患者接受了蒙克硬顶关节成形术治疗。平均随访23.9个月（9 - 47个月）后，对73名存活患者进行了临床和放射学复查。采用洛夫分类法发现，34例（48%）结果为优，21例（30%）为良。12例（17%）结果为中，4例（5%）为差。后一组结果差主要是由于影响行走的内科疾病。有临床和放射学证据表明非骨水泥假体有松动增加的趋势。然而，我们的病例数太少，无法就此得出明确结论。我们使用蒙克硬顶假体的经验是令人满意的，但需要更长时间的观察来确定这种假体对于股骨颈囊内骨折是否优于传统类型。
