摘　　要：髁突骨折对颞颌关节的影响有许多研究。但骨折后髁突骨密度及力学性能的变化尚未见报道。本文应用双能Ｘ线骨密度仪及生物力学方法观察了幼年期小型猪髁突纵行骨折对髁突的影响。结果显示：髁突纵行骨折引起髁突骨密度减低及生物力学性能下降。There were many reports on the effects of condylar fracture on TMJ, but no report about bone density and biomechanical changes of condyle after condylar fracture. In this study, the effects of longitudinal condylar fracture on TMJ in the childhood miniature pig were observed by using “DEXA” and “biological mechanics” methods. The results showed: longitudinal fractue apparently decreased the condylar bone density and mechanical function.
