A sample of 91 patients who had suffered from condylar fractures in the years 1970-1977 could be followed up. The mean follow up period was 19.8 years. As a prognostic relevant parameter the patient's age at the time of the accident as well as the type of the fracture where taken into account. Clinically young (8-11 years at the time of the accident) patient's with no or low grade dislocation showed the best results. Almost 36% of the patients with high grade dislocation or luxation presented measurable pathological changes during function. The condylar movement was assessed by using 3D-optoelectronic measurement. Despite severe radiographic alterations and hindered condylar translation in cases with high grade dislocation or luxation, mouth opening was not restricted in the majority of the patients. It seems that the lack of condylar translation is compensated by extensive rotation.
对1970年至1977年间发生髁突骨折的91例患者进行了随访。平均随访时间为19.8年。将事故发生时患者的年龄以及骨折类型作为与预后相关的参数进行考虑。临床上，事故发生时年龄较小（8 - 11岁）且无脱位或轻度脱位的患者效果最佳。几乎36%的高度脱位或半脱位患者在功能期间出现了可测量的病理变化。通过三维光电测量评估髁突运动。尽管在高度脱位或半脱位的病例中存在严重的影像学改变和髁突平移受阻，但大多数患者的张口不受限。似乎髁突平移的缺乏通过广泛的旋转得到了补偿。
