The purpose of this study was retrospectively to analyze the risk factors for non-union in Anderson-D'Alonzo type III odontoid fractures with conservative treatment.
25 patients with type III fractures were analyzed. Coronal and sagittal tilt as well as sagittal and lateral mass gaps were measured by using computed tomography.
The non-union group had significantly higher age, greater coronal tilt and lateral mass gap. Especially, the lateral mass gap was >2 mm in all cases with non-union.
Higher age, coronal tilt, and lateral mass gap were significant risk factors for non-union.
本研究旨在回顾性分析采用保守治疗的Anderson-D’Alonzo III型齿状突骨折不愈合的危险因素。
对25例III型骨折患者进行分析。使用计算机断层扫描测量冠状面和矢状面倾斜度以及矢状面和侧块间隙。
不愈合组患者年龄显著更大,冠状面倾斜度和侧块间隙更大。特别是,所有不愈合病例的侧块间隙均>2 mm。
年龄较大、冠状面倾斜度和侧块间隙是不愈合的重要危险因素。
