The authors have treated 14 cases of spontaneous rupture of extensor pollicis longus tendon after fractures of the distal end of the radius, most of which were undisplaced or only slightly displaced. A microvascular study on five cadavers revealed that this tendon is subject to mechanical bending and attrition, has no mesotenon and has a poorly vascularised portion about 5 mm in length, which may be a cause of spontaneous rupture of the tendon.
作者治疗了14例桡骨远端骨折后拇长伸肌腱自发性断裂的病例，其中大多数骨折无移位或仅轻微移位。对5具尸体进行的微血管研究表明，该肌腱受到机械性弯曲和磨损，没有腱系膜，且有一段约5毫米长的血管化不良区域，这可能是肌腱自发性断裂的一个原因。
