中文摘要:
      目的 探讨EOSTM 3D影像系统诊断复发性髌骨脱位的可靠性和稳定性。方法 回顾性分析2022年3月至2023年3月西安交通大学附属红会医院运动医学中心收治的22例(26膝)复发性髌骨脱位病人的影像学资料,两位影像学医生同时使用EOSTM系统测量病人下肢力线,使用sterEOS软件对影像图片进行3D模型重建,并在三维模型中测量胫骨结节-股骨滑车沟(tibial tubercle-trochlear groove,TT-TG)间距,记录每次测量所需的时间和相关参数。所有病人同期进行常规膝关节CT扫描及三维重建。将EOSTM 3D影像和CT扫描测量的TT-TG数值进行比较,采用一致性检验研究和Bland-Altman分析图评价测量结果数据的可靠性和稳定性。结果 进行EOSTM下肢力线测量时,不同测量者间测量的股骨和胫骨长度、膝关节内外翻角度及股骨胫骨旋转角度之间差异无统计学意义(P>0.05)。病人常规下肢CT扫描及三维重建测量时间为(21.8±3.2) min(13~29 min),EOSTM 3D测量时间为(6.3±1.8) min(4~11 min),差异有统计学意义(t=12.693,P<0.001)。两位医生使用EOSTM 3D测量TT-TG值的组内相关系数为0.791,使用常规CT测量的组内相关系数为0.843,两种测量方法组内一致性均较好。Bland-Altman分析结果显示两位测量者分别有96.2%(25/26)、92.3%(24/26)的点位于±1.96标准差范围内,显示使用常规CT三维重建和EOSTM 3D测量TT-TG值具备较好的一致性和稳定性。结论 使用EOSTM 3D影像系统测量复发性髌骨脱位病人的TT-TG值,具有良好的可靠性及可重复性,具有检查时间短、辐射低等优势,是评估此类病人下肢力线数据的一种快捷、可靠及稳定的方法。
英文摘要:
      Objective To explore the reliability and stability of EOSTM 3D imaging system in diagnosing recurrent patellar dislocation. Methods The imaging data of 22 patients (26 knees) with recurrent patellar dislocation treated in Sports Medicine Center of Xi'an Jiaotong University Affiliated Honghui Hospital from March 2022 to March 2023 were retrospectively analyzed. Two radiologists simultaneously performed EOSTM to obtain the patient's force line measurement values of the lower extremities. The 3D model of the image images was reconstructed using sterEOS software, and the tibial tubercle trochlear groove (TT-TG) values were measured in the 3D model. The time and relevant parameters required for each measurement were recorded. All patients underwent routine knee CT scan and 3D reconstruction at the same time. The TT-TG values measured by EOSTM 3D image and CT scan were compared, and the reliability and stability of the measured data were studied by consistency check and Bland-Altman figure. Results There was no significant difference in the length of femur and tibia, the varus angle of knee joint and the rotation angle of femur and tibia between different measurers when measuring the lower limb force line of EOSTM in all patients (P>0.05). The measurement time of conventional lower limb CT scan and 3D reconstruction was (21.8±3.2) min (13-29 min), while the EOSTM 3D measurement time was (6.3±1.8) min (4-11 min), with statistically significant differences (t=12.693, P<0.001). The correlation coefficient of TT-TG measured by EOSTM 3D between the two doctors and conventional CT were 0.791, 0.843, and the consistency between the two methods was good. The Bland-Altman plot showed that 96.2% (25/26) and 92.3% (24/26) of the points of the two measurers were within the ±1.96 standard deviation range, respectively, indicating that the TT-TG values measured by conventional CT 3D reconstruction and EOSTM 3D had good agreement and stability. Conclusion The use of EOSTM 3D imaging system to measure TT-TG values in patients with recurrent patellar dislocation has good reliability and repeatability. Its advantages of short examination time and low radiation will provide a fast, reliable and stable method for clinicians to evaluate the lower limb force line data of such patients.
