The temporomandibular joints of 64 patients and the hand joints of 62 patients with mandibular pain and/or dysfunction were exposed in oblique lateral transcranial, transmaxillary, and dorso-volar projections. The relationship between radiographic signs generally ascribed to osteoarthrosis was investigated. Indices were constructed to quantify the radiographic findings in the two joints. In the temporomandibular joint statistically significant age-independent correlations were found between flattening of the lateral part of the condyle, subcortical sclerosis of the condyle and reduced joint space. In the hand joints statistically significant age-independent correlations were found between osteophytes, subcortical sclerosis, eroded/absent cortical outlining, reduced/obliterated joint space and dislocations. No statistically significant correlation could be found between radiographic findings in the temporomandibular and hand joints. It is concluded that the radiographic signs in the temporomandibular joint of reduced joint space, subcortical sclerosis of the condyle and flattening of the lateral part of the condyle are interrelated and probably characteristic of osteoarthrosis, and that these relationships are similar to those that occur in the hand joints.
对64例患有下颌疼痛和/或功能障碍患者的颞下颌关节以及62例患者的手部关节，分别采用斜位经颅、经上颌和掌背位投照进行显像。研究了通常归因于骨关节炎的影像学征象之间的关系。构建指数以量化两个关节的影像学表现。在颞下颌关节中，发现髁突外侧部分变平、髁突皮质下硬化和关节间隙变窄之间存在与年龄无关的统计学显著相关性。在手部关节中，发现骨赘、皮质下硬化、皮质轮廓侵蚀/消失、关节间隙变窄/闭塞和脱位之间存在与年龄无关的统计学显著相关性。在颞下颌关节和手部关节的影像学表现之间未发现统计学显著相关性。结论是，颞下颌关节中关节间隙变窄、髁突皮质下硬化和髁突外侧部分变平的影像学征象相互关联，可能是骨关节炎的特征，并且这些关系与手部关节中出现的关系相似。
