本研究的目的是评价磁共振成像（MRI）结果在前移位复位（ADDR）和前移位不复位（ADDWR）之间的相关性。对200例有颞下颌关节紊乱病（TMD）症状的患者进行了临床检查。有130个关节ADDR和45个关节ADDWR; 88例患者根据临床和MRI诊断的两个观察者。对ADDR和ADDWR患者的MRI特征如位置、信号强度、椎间盘形态、退行性改变、积液、瘢痕组织、缺血性坏死和髁突过度活动进行评价。卡方检验用于确定ADDR和ADDWR中MRI特征之间的相关性。ADDR中退行性改变与信号强度增加、退行性改变与侧方移位、积液与椎间盘变形、积液与半脱位、信号强度增加与半脱位、伸长变形与信号强度增加、伸长变形与侧方移位之间存在显著相关性。ADDWR中椎间盘退变与积液、退变与信号强度降低、瘢痕组织与缺血性坏死、椎间盘变形与信号强度增高、椎间盘变形与信号强度降低之间存在显著相关性。这些MRI结果也与临床结果相关，然而，这种相关性似乎是一种协同模式，而不是一组明确的关系。这些MRI和不同的临床发现（如疼痛和功能障碍）之间的相关性也必须进行评估。在TMD的诊断和治疗计划中必须考虑存在的相关性，治疗后应监测TMD的体征和症状。
The aim of this study was to evaluate the correlations between magnetic resonance imaging (MRI) findings in anterior displacement with reduction (ADDR) and anterior displacement without reduction (ADDWR). Two hundred patients with temporomandibular disorder (TMD) symptoms were examined clinically by a clinician experienced with this disorder. There were 130 joints with ADDR and 45 joints with ADDWR; 88 patients were identified according to the clinical and MRI diagnoses of both observers. The MRI characteristics such as position, signal intensity, morphology of disc, degenerative changes, effusion, scar tissue, avascular necrosis, and condylar hypermobility were evaluated in the individual with ADDR and ADDWR. The Chi-square test was used to determine the correlation between MRI characteristics in the ADDR and the ADDWR. There were significant relationships between degenerative changes and increased signal intensity, degenerative changes and side-way displacement, effusion and the deformation of the disc, effusion and subluxation, increased signal intensity and subluxation, elongation deformation and increased signal intensity, and elongation deformation and side-way displacement in ADDR. There were significant relationships between degenerative changes and effusion, degenerative changes and decreased signal intensity, scar tissue and avascular necrosis, deformation of disc and increased signal intensity, as well as deformation of disc and decreased signal intensity in ADDWR. These MRI findings also correlated with the clinical findings, however, this correlation appears to be a synergistic pattern rather than a set of clear-cut relationships. The correlations between these MRIs and different clinical findings such as pain and dysfunction also must be evaluated. Existing correlations must be considered in the diagnosis and treatment planning of TMD, and signs and symptoms of TMD should be monitored after treatment.
