Surgical intracapsular concylar fractures were initiated on young monkeys followed by prolonged intermaxillary fixation in an effort to create facial asymmetry and induce temporomandibular joint ankylosis. Implanted head positioners and metallic bone markers were used to document developing facial asymmetry in all animals. Vertical opening capabilities were fully recovered and the procedures had no discernible functional impact. Slight limitation of movement persisted only in the translation of the damaged condyles. It was concluded that trauma followed by long term fixation had no effect in promoting ankylosis or significant limitation of jaw movement. It is suggested that when considering the role of trauma in the aetiology of ankylosis, attention be given to those factors which may complicate an existing trauma.
在幼年猴子身上制造髁状突囊内骨折，随后进行长时间的颌间固定，以造成面部不对称并诱发颞下颌关节强直。使用植入式头部定位器和金属骨标记物记录所有动物面部不对称的发展情况。垂直开口能力完全恢复，这些操作没有明显的功能影响。仅受损髁状突的平移存在轻微的运动受限。得出的结论是，创伤后长期固定对促进关节强直或显著限制下颌运动没有影响。建议在考虑创伤在关节强直病因中的作用时，应关注那些可能使现有创伤复杂化的因素。
