Fractures of the occipital condyle are rare; 32 cases have been reported in the literature. Here, the authors describe four additional cases of occipital condylar fracture. Anderson's classification is used: type I fracture: comminution of the condyle without significant displacement; type II: basilar fracture extending into the condyle; type III: condylar avulsion. The possible mechanisms are identified. Computed tomography proved essential in diagnosing these fractures; coronal reconstructions together with axial scans are particularly helpful. Three-dimensional reconstruction did not prove essential in diagnosing these fractures.
枕髁骨折较为罕见；文献中已报道32例。在此，作者描述另外4例枕髁骨折病例。采用安德森分类法：I型骨折：髁粉碎但无明显移位；II型：基底骨折延伸至髁；III型：髁撕脱。确定了可能的机制。计算机断层扫描在诊断这些骨折中被证明至关重要；冠状位重建结合轴位扫描特别有帮助。三维重建在诊断这些骨折中并非必不可少。
