摘要

计算机导航在全髋关节置换术（THA）中的应用正在上升。计算机导航有两种常用的模式，无图像（ILCN）和基于图像（IBCN）。本研究的目的是比较在同一THA病例中使用ILCN和IBCN的倾斜度和前倾度测量。方法选取100例同时使用ILCN和IBCN的后路tha。术中记录ILCN和IBCN髋臼成分倾斜和前倾测量。比较了脑内ILCN和IBCN的平均倾斜和前倾测量值。记录不一致病例（>；5°差异）；线性回归用于确定是否有任何混杂因素与不一致风险增加有关。结果ILCN与IBCN的平均倾斜度和前倾度无显著差异。然而，在21%和32%的病例中，ILCN和IBCN之间的倾斜度和前倾度测量分别不一致。体重指数（P = .007）和既往腰椎融合（P = .012）与前倾不一致性增加相关。不一致与脱位率之间无关联。结论：病例内ILCN和IBCN的比较表明，在超过20%的病例中，两种技术之间的测量结果不一致。不协调的危险因素包括腰椎融合和体重指数升高。

Imageless vs Image-Based Computer Navigation in Total Hip Arthroplasty: An Intracase Comparison Shows Variability Between Technologies

Background

The use of computer navigation in total hip arthroplasty (THA) is on the rise. Computer navigation has 2 commonly utilized modalities, imageless (ILCN) and image-based (IBCN). The aim of this study was to compare ILCN and IBCN inclination and anteversion measurements when utilized in the same THA case.

Methods

One-hundred consecutive primary or revision posterior THAs in which both ILCN and IBCN were utilized in the same case were included. Intraoperative ILCN and IBCN acetabular component inclination and anteversion measurements were recorded. Mean inclination and anteversion measurements from intracase ILCN and IBCN were compared. Discordant cases (>5° differences) were recorded; linear regression was used to determine if any confounding factors were associated with an increased risk of discordance.

Results

There was no significant difference in mean inclination or anteversion between ILCN and IBCN. However, in 21% and 32% of cases, inclination and anteversion measurements, respectively, were discordant between ILCN and IBCN. Body mass index (P = .007) and prior lumbar spine fusion (P = .012) were correlated with increased discordance of anteversion. There was no association between discordance and dislocation rate.

Conclusions

This intracase comparison of ILCN and IBCN demonstrates that in over 20% of cases, measurements between the 2 technologies are discordant. Risk factors for discordance include lumbar spine fusion and increased body mass index.

期刊介绍： Arthroplasty Today is a companion journal to the Journal of Arthroplasty. The journal Arthroplasty Today brings together the clinical and scientific foundations for joint replacement of the hip and knee in an open-access, online format. Arthroplasty Today solicits manuscripts of the highest quality from all areas of scientific endeavor that relate to joint replacement or the treatment of its complications, including those dealing with patient outcomes, economic and policy issues, prosthetic design, biomechanics, biomaterials, and biologic response to arthroplasty. The journal focuses on case reports. It is the purpose of Arthroplasty Today to present material to practicing orthopaedic surgeons that will keep them abreast of developments in the field, prove useful in the care of patients, and aid in understanding the scientific foundation of this subspecialty area of joint replacement. The international members of the Editorial Board provide a worldwide perspective for the journal''s area of interest. Their participation ensures that each issue of Arthroplasty Today provides the reader with timely, peer-reviewed articles of the highest quality.
