Heterotopic ossification following an uncemented total hip arthroplasty should theoretically demonstrate a higher incidence than a cemented arthroplasty. This is due to increased production of bone debris following vigorous femoral canal and pelvic reaming, which should provide increased stimulatory factors for ectopic bone production. The authors examined 196 consecutive primary total hip arthroplasties prospectively for 1 year. The overall incidence of heterotopic ossification was 26% with only one patient having a Grade III (severe) amount of ectopic bone. This incidence is consistent with those reported in cemented total hip arthroplasties. This paper does not support Puzas et al theory of bone dust providing a stimulatory factor for the production of heterotopic bone.
理论上，非骨水泥型全髋关节置换术后的异位骨化发生率应高于骨水泥型关节置换术。这是因为在进行股骨骨髓腔和骨盆扩髓时会产生更多的骨碎屑，这应为异位骨生成提供更多的刺激因素。作者对196例连续的初次全髋关节置换术患者进行了为期1年的前瞻性研究。异位骨化的总体发生率为26%，只有1例患者出现III级（严重）异位骨量。该发生率与骨水泥型全髋关节置换术的报道一致。本文不支持普扎斯等人提出的骨屑为异位骨生成提供刺激因素的理论。
