Partial or total hip replacement is the method of choice for displaced femoral neck fractures (FNF) treatment. Dislocation is a major complication, accounting for about 3.8% of cases for hemiarthroplasty (HA) and 10% for total hip arthroplasty (THA). Dual-mobility (DM) socket in total hip arthroplasty showed a very low rate of dislocation in both primary and revision setting THA. Some literature reports show good results with low dislocation rates also in FNF treatment at short term follow-up. Aim of the study was to evaluate clinical and radiographic results of DM-THA in FNF treatment at mid-term follow up.
Study population counted 31 implants in 30 patients treated with DM-THA for FNF between January 2010 and December 2012. Dislocation rate was identified, and HHS and OHS were completed. Twenty-four patients underwent also radiographic evaluation to assess cup integration and sings of loosening.
No episodes of hip dislocation nor intraprosthetic dislocation were found. Other postoperative complications were recorded in 9,67%. HHS and OHS showed a mean value of 81,22 and 37,37, respectively. There were no cases of clinical and radiographic signs of implant loosening.
The present study confirms the good clinical results, low complications and very low dislocation rate with DM THA for FNF treatment.
部分或全髋关节置换术是治疗移位型股骨颈骨折（FNF）的首选方法。脱位是一种主要并发症，在半髋关节置换术（HA）中约占病例的3.8%，在全髋关节置换术（THA）中占10%。全髋关节置换术中的双动（DM）髋臼杯在初次和翻修THA中均显示出极低的脱位率。一些文献报道显示，在短期随访的FNF治疗中，脱位率低也取得了良好的效果。本研究的目的是评估中期随访时DM-THA治疗FNF的临床和影像学结果。
研究人群包括2010年1月至2012年12月期间30例接受DM-THA治疗FNF的患者中的31个植入物。确定脱位率，并完成髋关节 Harris 评分（HHS）和牛津髋关节评分（OHS）。24例患者还接受了影像学评估，以评估髋臼杯的整合情况和松动迹象。
未发现髋关节脱位或假体内部脱位事件。其他术后并发症发生率为9.67%。HHS和OHS的平均值分别为81.22和37.37。没有植入物松动的临床和影像学迹象病例。
本研究证实了DM THA治疗FNF具有良好的临床效果、低并发症和极低的脱位率。
