Four adults who had symptomatic instability of the ankle had an associated os subfibulare. Operative exploration revealed the ossicle to represent a non-union of an avulsion fracture of the anterior talofibular ligament. These findings suggest that an os subfibulare represents an avulsion fracture that may or may not be associated with laxity of the anterior talofibular ligament, rather than being a normal variant.
四名有症状性踝关节不稳定的成年人伴有腓下骨。手术探查发现该小骨代表距腓前韧带撕脱骨折的不愈合。这些发现表明，腓下骨代表一种撕脱骨折，可能与距腓前韧带松弛有关，也可能无关，而不是一种正常变异。
