摘要
目的：比较使用标准和高偏移柄进行THA手术的倾向匹配患者五年后的临床和放射学结果：作者回顾性分析了2015年9月1日至2017年12月31日期间使用全羟基磷灰石涂层带环柄、标准偏移量（n = 365）或高偏移量（n = 110）的连续系列初次THA手术。收集的结果包括：改良哈里斯髋关节评分（mHHS）、牛津髋关节评分（OHS）、遗忘关节评分（FJS），以及包括肢长差异（LLD）、茎杆下沉和茎杆放射状突起在内的放射学测量结果：倾向评分匹配结果显示每组有80个髋关节。术前，患者的人口统计学、手术数据和放射学测量结果无明显差异，但标准偏移组的股骨明显较小（40.0 ± 7.5 vs 48.4 ± 6.2，P 结论：标准偏移组的股骨较小（40.0 ± 7.5 vs 48.4 ± 6.2，P本匹配队列研究发现，就五年后的临床和放射学结果而言，标准偏移量与高偏移量直型全羟基磷灰石涂层骨圈柄在初级 THA 中没有明显差异。这些研究结果可能表明，与非骨水泥胶合的标准偏移基台相比，非骨水泥胶合的高偏移基台不会增加发生放射性损伤和松动的风险。
No differences in clinical and radiographic outcomes between standard versus high offset collared stems for primary total hip arthroplasty at five years follow-up.
Purpose: To compare clinical and radiographic outcomes of propensity-matched patients undergoing THA using standard versus high offset stems at five years.
Methods: The authors retrospectively reviewed a consecutive series of primary THAs performed between 01/09/2015-31/12/2017 using a fully-hydroxyapatite coated collared stem, with either a standard (n = 365) or high (n = 110) offset. Outcomes collected included: modified Harris Hip Score (mHHS), Oxford Hip Score (OHS), Forgotten Joint Score (FJS), and radiographic measurements including limb length discrepancy (LLD), stem subsidence, and stem radiolucencies.
Results: Propensity score matching resulted in 80 hips per group. Preoperatively there were no significant differences in patient demographics, surgical data and radiographic measurements, except the standard offset group had significantly smaller femoral (40.0 ± 7.5 vs 48.4 ± 6.2, p < 0.001), acetabular (92. ± 6.3 vs 94.8 ± 7.3, p = 0.011) and global (132.0 ± 10.3 vs 143.2 ± 8.2, p < 0.001) offsets compared to the high offset group. At a minimum five years follow-up, there were no significant differences in mHHS (93.2 ± 11.0 vs 93.1 ± 10.6, p = 0.553), OHS (45.1 ± 4.1 vs 45.3 ± 4.6, p = 0.623), and FJS (85.1 ± 19.3 vs 82.7 ± 23.0, p = 0.910). There were also no differences in radiographic measurements, including LLD (1.5 ± 4.8 vs 1.1 ± 3.5, p = 0.537), stem subsidence (0% vs 0%, p = 1.000), and stem radiolucencies (severe: 6% vs 1%, p = 0.152).
Conclusion: The present matched-cohort study found no significant differences between standard versus high offset straight fully-hydroxyapatite coated collared stems for primary THA in terms of clinical and radiographic outcomes at five years. These findings may suggest that uncemented collared high offset stems are not associated with an increased risk of radiolucencies and loosening compared to uncemented collared standard offset stems.
期刊介绍：
International Orthopaedics, the Official Journal of the Société Internationale de Chirurgie Orthopédique et de Traumatologie (SICOT) , publishes original papers from all over the world. The articles deal with clinical orthopaedic surgery or basic research directly connected with orthopaedic surgery. International Orthopaedics will also link all the members of SICOT by means of an insert that will be concerned with SICOT matters.
Finally, it is expected that news and information regarding all aspects of orthopaedic surgery, including meetings, panels, instructional courses, etc. will be brought to the attention of the readers.
Manuscripts submitted for publication must contain a statement to the effect that all human studies have been approved by the appropriate ethics committee and have therefore been performed in accordance with the ethical standards laid down in the 1964 Declaration of Helsinki. It should also be stated clearly in the text that all persons gave their informed consent prior to their inclusion in the study. Details that might disclose the identity of the subjects under study should be omitted.
Reports of animal experiments must state that the "Principles of laboratory animal care" (NIH publication No. 85-23, revised 1985) were followed, as well as specific national laws (e.g. the current version of the German Law on the Protection of Animals) where applicable.
The editors reserve the right to reject manuscripts that do not comply with the above-mentioned requirements. The author will be held responsible for false statements or for failure to fulfil the above-mentioned requirements.
