The os trigonum is one of the most frequent accessory bones of the foot. It is located dorsal of the talus. Os trigonum syndrome means a typical pain syndrome localized in the back-foot caused by this ossicle. This syndrome occurs mostly in man with sports activities accompanied with intensive stress to different parts of the foot. It can be caused particularly by standing on the toe in the "en-pointe-position" in ballet dancers when the flexor hallucis tendon is under maximal tension or by activities accompanied with maximal plan-tarflexion in soccer players for instance. Typical complaints, findings and different therapeutic procedures are demonstrated in two cases. Therapy includes different non-operative methods. Resistance to non-operative procedures is indication for operative therapy. Excision of this ossicle is surgical therapy of first choice.
三角骨是足部最常见的副骨之一。它位于距骨的背侧。三角骨综合征是指由这块小骨引起的、局限于后足的典型疼痛综合征。这种综合征大多发生在从事体育活动且足部不同部位承受高强度压力的男性身上。特别是芭蕾舞演员以“足尖站立姿势”踮脚尖时，拇长屈肌腱处于最大张力状态，或者例如足球运动员进行最大程度跖屈的活动时，都可能引发该综合征。通过两个病例展示了典型症状、检查结果及不同的治疗方法。治疗包括不同的非手术方法。对非手术治疗无反应是手术治疗的指征。切除这块小骨是首选的手术治疗方法。
