Although modular head-neck combinations for femoral components are convenient and useful, theoretical concerns make them less attractive. In a consecutive series of 100 primary cementless total hip arthroplasties, the neck length chosen for the broach trial reduction was compared with the final neck length chosen after the actual femoral component had been impacted. In 19%, the neck length was changed after insertion of the femoral component. As a result, leg-length inequality or wastage of these femoral components would have resulted. For cementless femoral components, the ability to adjust neck length after component impaction remains important.
尽管用于股骨部件的模块化头颈组合方便且实用，但理论上的问题使其吸引力降低。在连续的100例初次非骨水泥型全髋关节置换术中，将用于扩髓试模复位时选择的颈长与实际股骨部件打入后最终选择的颈长进行了比较。19%的病例在股骨部件插入后颈长发生了改变。结果，将会导致肢体长度不等或这些股骨部件的浪费。对于非骨水泥型股骨部件，在部件打入后调整颈长的能力仍然很重要。
