摘要

背景和目的:多项研究报告了基于聚乙二醇/聚对苯二甲酸丁二醇酯(PEG/PBT)的股骨骨水泥限制器周围的骨溶解情况。我们的目标是评估和比较三种不同塞子设计的溶骨情况:慢速生物降解 PEG/PBT 骨水泥限制器、快速生物降解明胶骨水泥限制器和不可生物降解聚乙烯塞子:在一项回顾性多中心队列研究中,提取了2008年至2012年间接受全髋关节置换术的患者的病历数据。共纳入了 961 例髋关节。在术后常规随访中测量了塞子中心内皮质和外皮质之间的皮质比率。三家医院的中位随访时间均为 3.5 年(1.4-7.3 年)。主要结果是最终随访时的前正位(AP)X光片上的骨溶解证据(即皮质比率[CR]的差异):结果:在PEG/PBT骨水泥限制器周围发现了进行性骨溶解,表现为皮质比率显著增加(ΔCR 0.067 (95% CI, 0.063-0.071))。从顶端假体到塞子的距离和塞子的大小是预测皮质比率增加的独立因素:我们的多中心队列显示,PEG/PBT 骨水泥限制器周围的皮质比率会随着时间的推移而增加。医生应该意识到这一事实,并建议加强对接受这种骨水泥限制器的患者的随访。

Comparison of osteolysis around 3 different cement restrictors in total hip arthroplasty.

Background and aim: Several studies reported osteolysis around polyethylene glycol/polybutylene terephthalate (PEG/PBT) based femoral cement restrictors. Our goal was to evaluate and compare osteolysis around 3 different plug designs: the slow biodegradable PEG/PBT cement restrictor; the fast biodegradable gelatin cement restrictor; and the non-biodegradable polyethylene plug.

Patients and methods: In a retrospective multicentre cohort study chart data were extracted of patients who received a total hip arthroplasty between 2008 and 2012. A total of 961 hips were included. Cortical ratio between inner and outer cortices at the centre of the plug was measured on routine postoperative follow-up moments. Median follow up of all 3 hospitals was 3.5 years (1.4-7.3). The primary outcome was evidence of osteolysis (i.e. the difference in cortical ratio [CR]) on anteroposterior (AP) radiographs at final follow-up.

Results: Progressive osteolysis was found around the PEG/PBT cement restrictor represented by a significantly increasing cortical ratio (ΔCR 0.067 (95% CI, 0.063-0.071). Distance from tip prosthesis to plug and size of the plug were found to be independent factors in predicting increased cortical ratio.

Conclusions: Our multicentre cohort shows increase of cortical ratio around the PEG/PBT cement restrictor which progresses over time. Physicians should be aware of this fact and are advised to intensify follow-up of patients who received this cement restrictor.

期刊介绍: HIP International is the official journal of the European Hip Society. It is the only international, peer-reviewed, bi-monthly journal dedicated to diseases of the hip. HIP International considers contributions relating to hip surgery, traumatology of the hip, prosthetic surgery, biomechanics, and basic sciences relating to the hip. HIP International invites reviews from leading specialists with the aim of informing its readers of current evidence-based best practice. The journal also publishes supplements containing proceedings of symposia, special meetings or articles of special educational merit. HIP International is divided into six independent sections led by editors of the highest scientific merit. These sections are: • Biomaterials • Biomechanics • Conservative Hip Surgery • Paediatrics • Primary and Revision Hip Arthroplasty • Traumatology
