The temporomandibular (TMJ) and hand joints of 64 patients with psoriatic arthritis (PA) were examined radiographically with panoramic tomography and dorsovolar projection. The associations between radiographic signs in the condyle of the TMJ and finger joints were analyzed with Pearson's product-moment correlation coefficient. Twenty-six patients (41%) had radiographic signs in their TMJs. Arthritic signs were seen in 14 (22%) and degenerative signs in 12 (19%) patients. Fifty-five patients (86%) had radiographic signs in their hands; 33 patients (52%) had arthritic and 22 (34%) degenerative signs. In the TMJ statistically significant correlations were found among erosion, flattening, and cortical sclerosis and also between osteophyte and cortical sclerosis. In the finger joints erosion correlated significantly with dislocation and loss of space. Erosion in the condyle of the TMJ was the only sign that correlated with changes in the finger joints such as erosion, dislocation, and ankylosis. Erosion in the TMJ also correlated with erosion in the metacarpophalangeal joint and wrist.
对64例银屑病关节炎（PA）患者的颞下颌关节（TMJ）和手部关节进行全景断层扫描和背腹位投照的X线检查。采用Pearson积差相关系数分析TMJ髁突和手指关节的X线征象之间的相关性。26例患者（41%）TMJ有X线征象。14例（22%）有关节炎征象，12例（19%）有退行性变征象。55例患者（86%）手部有X线征象；33例（52%）有关节炎征象，22例（34%）有退行性变征象。在TMJ中，发现侵蚀、扁平及皮质硬化之间存在统计学显著相关性，骨赘与皮质硬化之间也存在相关性。在手指关节中，侵蚀与脱位及间隙丧失显著相关。TMJ髁突的侵蚀是唯一与手指关节变化（如侵蚀、脱位和关节强直）相关的征象。TMJ的侵蚀也与掌指关节和腕关节的侵蚀相关。
