肩锁关节脱位的影像对比研究

目的探讨X线、CT及MR三种影像诊断技术对肩锁关节脱位的诊断价值。方法回顾性分析35例经手术或关节镜证实的肩锁关节脱位患者的X线平片、CT和MRI材料,按照Rockwood分型标准进行分型,对照手术或关节镜结果,比较三种影像学方法诊断肩锁关节脱位的准确率、漏诊率和误诊率。结果在本组35例肩锁关节脱位病例诊断中,X线平片诊断符合28例,占80.0%(28/35);漏诊3例,占8.6%(3/35);误诊4例,占11.4%(4/35)。CT诊断符合30例,占85.7%(30/35);漏诊2例,占5.7%(2/35);误诊3例,占8.6%(3/35)。MR诊断符合33例,占94.3%(33/35);漏诊1例,占2.85%(1/35);误诊1例,占2.85%(1/35)。结论 MRI能够更为精确地显示肩锁关节脱位的韧带损伤情况,为临床正确分型及确定治疗方案提供了可靠依据。

The Evaluation study on diagnostic value of X-ray, CT, MRI on acromioclavicular joint dislocation

Objective To evaluate the value of X-ray,CT and MR imaging in the diagnosis of acromioclavicular joint dislocation.Methods A retrospective study was performed to evaluate 35 acromioclavicular joint dislocations.Retrospective analysis of the X-ray,CT and MRI material of 35 cases which was confirmed by surgery or arthroscopic.According to Rockwood classification criteria,X-ray,CT and MRI were compared with surgery or arthroscopic result by the accuracy rate and missed diagnosis rate and misdiagnosis rate.Results X-ray diagnosis in 28 cases,accounting for 80.0%(28/35);missed in 3 cases,accounting for 8.6%(3/35);misdiagnosed in 4 cases,accounting for 11.4%(4/35).CT diagnosis in 30 cases,accounting for 85.7%(30/35);missed in 2 cases,accounting for 5.7%(2/35);misdiagnosed in 3 cases,accounting for 8.6%(3/35).MR diagnosis in 33 cases,accounting for 94.3%(33/35);missed in 1 case,accounting for 2.85%(1/35);misdiagnosed in 1 case,accounting for 2.85%(1/35).Conclusion MRI can help to detect the ligament injury of acromioclavicular joint dislocation and make accurate clinical classification in oder to determine the correct treatment program.
