Abstract：
UNASSIGNED: The objective of this study was to assess the long-term survival rate, complications, as well as the clinical and radiological outcomes of hemiarthroplasty and total hip arthroplasty using constrained polyethylene liners in patients with ischemic stroke.
UNASSIGNED: This study was a retrospective cohort study that included patients with ischemic stroke who underwent hip arthroplasty from March 2010 to September 2017. In the Constrained Acetabular Liners (CAL) group, patients received an uncemented acetabular shell with a constrained polyethylene liner. The Dual Mobility (DM) group underwent hemiarthroplasty (HA). Additionally, hip function, range of motion, quality of life, the incidence of clinical complications, and prosthesis stability were investigated.
UNASSIGNED: 96 patients with unilateral femoral neck fractures who underwent hip replacement with CAL were included in the CAL group, while 103 patients who underwent hip replacement with a dual mobility head were included in the DM group. VAS, and SF-36 data were available for both CAL and DM groups. At the 1-year postoperative follow-up, the HHS in the CAL group was significantly lower than that in the DM group (80.83 ± 3.91 vs. 83.17 ± 4.15, P < 0.05). The VAS score in the CAL group peaked at the 1-year follow-up (2.07 ± 0.91 vs. 1.49 ± 0.85, P < 0.05). However, there were no significant differences between the two groups in terms of HSS, VAS, and SF-36 at the last follow-up after surgery. Operative time and the amount of bleeding in the DM group were significantly lower than those in the CAL group (105.30 ± 29.68 vs. 94.85 ± 31.07; 355.11 ± 123.95 vs. 302.22 ± 107.68, P < 0.05). Additionally, there was no significant difference in the mean leg length discrepancy between the two groups.
UNASSIGNED: The clinical, imaging, and postoperative complications of the CAL and DM groups were analyzed. The prognosis for DM appears to be more beneficial for early patient recovery, but a higher likelihood of recurrent dislocation is observed. CAL offers excellent stability for primary THA in high-risk patients; however, attention should be given to preventing aseptic loosening.

摘要：
■这项研究的目的是评估长期生存率，并发症,以及缺血性卒中患者使用约束聚乙烯衬垫的半髋关节置换术和全髋关节置换术的临床和放射学结果。
本研究是一项回顾性队列研究，纳入了2010年3月至2017年9月接受髋关节置换术的缺血性卒中患者。在“约束髋臼衬垫(CAL)”组中，患者接受了带有约束聚乙烯衬里的非骨水泥髋臼壳。双流动性（DM）组行半髋关节置换术（HA）。此外,髋关节功能,运动范围,生活质量,临床并发症的发生率，和假体的稳定性进行了研究。
■96例单侧股骨颈骨折行CAL髋关节置换术的患者被纳入CAL组，而接受双动头髋关节置换术的103例患者被纳入DM组.VAS,和SF-36数据可用于CAL和DM组。术后1年随访,CAL组HHS明显低于DM组(80.83±3.91vs.83.17±4.15,P<0.05)。CAL组的VAS评分在1年随访时达到峰值（2.07±0.91vs.1.49±0.85,P<0.05)。然而,两组在HSS方面没有显着差异，VAS,和SF-36在手术后的最后一次随访。DM组的手术时间和出血量明显低于CAL组（105.30±29.68vs.94.85±31.07;355.11±123.95vs.302.22±107.68,P<0.05)。此外,两组之间的平均腿长差异没有显着差异。
■临床，成像,分析CAL组和DM组的术后并发症。DM的预后似乎更有利于患者的早期恢复，但是观察到复发性脱位的可能性更高。CAL为高危患者的原发性THA提供了出色的稳定性；然而，应注意防止无菌性松动。
