BACKGROUND Patients undergoing primary total hip arthroplasty (THA) with prior lumbar spine fusion (LSF) are a high-risk group for instability with reported incidence of dislocation as high as 8.3% using fixed bearing femoral heads. Purpose of this study was to determine risk of post-operative instability in patients undergoing primary THA with a history of prior LSF using dual mobility acetabular cups. METHODS This was a multicenter retrospective study with 93 patients undergoing primary THA using a dual mobility cup with a prior history of instrumented LSF. There were 56 females and 47 males with an average age of 66 years (46-87) and average BMI of 30 with mean follow-up of 2.7 years (range 12-124 months). Surgical approach included posterior (63), direct lateral (15), anterior (11), and direct superior (4). Forty-four percent had one level lumbar fusion, 29% with two levels, and 15% with three or more levels fused. The primary outcome investigated was instability. RESULTS There were no cases of instability or prosthetic joint infection in this group of patients with prior lumbar spine fusion undergoing primary THA using a dual mobility cup. There was one intra-operative periprosthetic femur fracture and one case of aseptic acetabular cup loosening. CONCLUSION Patients undergoing THA with prior LSF are at increased risk for instability due to loss of normal spinopelvic relationship. The use of dual mobility cups in patients with prior LSF undergoing primary THA appears promising with no cases of instability in this high-risk group of patients.

在先行全髋关节置换合并先前腰椎融合的患者中使用双重活动杯。

背景技术接受原先腰椎融合术(LSF)的原发性全髋关节置换术(THA)的患者是不稳定的高危人群,据报道,使用固定式股骨头置换术的脱位发生率高达8.3%。这项研究的目的是确定使用双活动髋臼杯接受原发性LSF病史的原发性THA患者的术后不稳定风险。方法这是一项多中心回顾性研究,其中93例患者在使用双活动杯的情况下接受了原发性THA,并具有LSF的既往病史。有56位女性和47位男性,平均年龄为66岁(46-87岁),平均BMI为30,平均随访时间为2.7年(范围12-124个月)。手术方法包括后路(63),直接外侧(15),前侧(11)和直接上上方(4)。44%的患者进行一级腰椎融合术,29%的患者进行两级腰椎融合术,15%的患者进行三级或更多级融合术。研究的主要结果是不稳定。结果本组既往没有腰椎或人工关节感染的患者,既往有腰椎融合的患者使用双活动杯进行了原发性THA。术中股骨假体周围骨折1例,无菌髋臼杯松弛1例。结论接受THA合并LSF的患者由于失去正常的脊柱盆腔关系而增加了不稳定的风险。在先前接受过原发性THA的LSF患者中使用双重活动杯似乎很有希望,在这种高风险患者中没有不稳定的病例。研究的主要结果是不稳定。结果本组既往没有腰椎或人工关节感染的患者,既往腰椎融合术接受了双活动杯的原发性THA治疗。术中股骨假体周围骨折1例,无菌髋臼杯松弛1例。结论接受THA合并LSF的患者由于失去正常的脊柱盆腔关系而增加了不稳定的风险。在先前接受过原发性THA的LSF患者中使用双重活动杯似乎很有希望,在这种高风险患者中没有不稳定的病例。研究的主要结果是不稳定。结果本组既往没有腰椎或人工关节感染的患者,既往有腰椎融合的患者使用双活动杯进行了原发性THA。术中股骨假体周围骨折1例,无菌髋臼杯松弛1例。结论接受THA合并LSF的患者由于失去正常的脊柱盆腔关系而增加了不稳定的风险。在先前接受过原发性THA的LSF患者中使用双重活动杯似乎很有希望,在这种高风险患者中没有不稳定的病例。术中股骨假体周围骨折1例,无菌髋臼杯松弛1例。结论接受THA合并LSF的患者由于失去正常的脊柱盆腔关系而增加了不稳定的风险。在先前接受过原发性THA的LSF患者中使用双重活动杯似乎很有希望,在这种高风险患者中没有不稳定的病例。术中股骨假体周围骨折1例,无菌髋臼杯松弛1例。结论接受THA合并LSF的患者由于失去正常的脊柱盆腔关系而增加了不稳定的风险。在先前接受过原发性THA的LSF患者中使用双重活动杯似乎很有希望,在这种高风险患者中没有不稳定的病例。
