摘要

目的:本研究旨在比较EOS中TT-TG测量与MRI在儿科人群中的相对可靠性和准确性。方法:年龄在16岁以下的患者均接受了MRI和EOS扫描。两位作者在两个不同的时间点记录了每个模态的TT-TG距离。在EOS图像中,在水平二维平面上测量两点之间的距离。在MRI图像中,以股骨后髁轴为参考平面进行。评估了每个模式和模式之间的内部和内部可靠性。结果:纳入患者27例(30膝),男性14例,女性13例,平均年龄13岁(范围7-16岁)。EOS扫描和MRI扫描的TT-TG平均距离为14 mm。在观察者之间和观察者内部分析中,两种成像方式都具有出色的可靠性(EOS为0.97 ICC, MRI为0.98 ICC)和可重复性(EOS为0.98-0.99 ICC, MRI为0.99 ICC)。然而,在比较两种成像方式(EOS与MRI)时,ICC是公平的(等级1为0.56 ICC,等级2为0.65 ICC)。结论:虽然EOS TT-TG测量是精确的和可重复的,但它们与MRI TT-TG测量只有适度的可比性。因此,在没有确定EOS特异性TT-TG值(表明需要进行远端复位手术)的情况下,EOS TT-TG测量不应用于决策。证据等级:二级。

The tibial tubercle-trochlear groove distance: a comparison study between EOS and MRI in the paediatric population.

Objective: This study aims to compare the relative reliability and accuracy of TT-TG measurements in EOS with that of MRI in a paediatric population.

Methods: Patients were included if they underwent both an MRI and EOS scans and were under the age of 16. Two authors recorded the TT-TG distances on each modality at two separate time points. In the EOS images, the distance between the two points was measured in the horizontal 2D plane. In the MRI images, it was done in the plane referenced by posterior femoral condylar axis. The intra- and inter-rater reliability was assessed in each modality and between modalities.

Results: Twenty-seven patients (30 knees), 14 males, and 13 females with an average age of 13 years (range: 7-16 years) were included in the study. The mean TT-TG distance on EOS scan and MRI scan was 14 mm. On inter- and intra-observer analysis, both imaging modalities had excellent reliability (0.97 ICC for EOS and 0.98 ICC for MRI inter-observer) and repeatability (0.98-0.99 ICC for EOS and 0.99 ICC for MRI for intra-observer). However, on comparing the two imaging modalities (EOS vs MRI), the ICC was fair (0.56 ICC for rater 1 and 0.65 ICC for rater 2).

Conclusion: While the EOS TT-TG measurements were precise and reproducible, they were only moderately comparable to MRI TT-TG measurements. Consequently, EOS TT-TG measurements should not be used for decision-making without the development of EOS-specific TT-TG values that indicate the need for distal realignment surgery.

Level of evidence: Level II.

期刊介绍: Skeletal Radiology provides a forum for the dissemination of current knowledge and information dealing with disorders of the musculoskeletal system including the spine. While emphasizing the radiological aspects of the many varied skeletal abnormalities, the journal also adopts an interdisciplinary approach, reflecting the membership of the International Skeletal Society. Thus, the anatomical, pathological, physiological, clinical, metabolic and epidemiological aspects of the many entities affecting the skeleton receive appropriate consideration. This is the Journal of the International Skeletal Society and the Official Journal of the Society of Skeletal Radiology and the Australasian Musculoskelelal Imaging Group.
